Water Supply

Provision of safe, adequate water is a basic necessity for the healthy living of a community. In this section, demand of potable water in the New Capital City Area has been dealt with. On the basis of the total water demand in different design years, identification of the water source, requirement of treatment
plant, and storage reservoirs have been estimated. Presently, the area is rural with ponds, small reservoirs and canals. It is also dotted with small to very
large water tanks, which are used by the villagers for ablutions, washing cattle and for irrigation. The Mahanadi Main Canal that runs along the western bank of the river principally feeds the extensive canal network in the New Capital City region.

10.1.1 Water Supply Norms Prescribed By CPHEEO

The per capita domestic requirements as per norms prescribed by Central Public Health and Environmental Engineering Organization (CPHEEO), Ministry of Urban Development, and Govt. of India are as under:

WATER SUPPLY NORMS FOR NAYA RAIPUR

Capture29

Considering recommendations of CPHEEO Manual for Water Supply, Master Plan for Delhi 2001 and
Raipur Development Plan 2005, the following water supply norms have been adopted for the Naya
Raipur City:
Residential areas 150 litres per capita per day
Commercial areas and Government Offices 70 litres per employee per day
Hotels 180 litres per bed per day
Hospital
a. With beds more than 100 450 litres per bed per day
b. With beds less than 100 340 litres per bed per day
Institutional/ Industrial and Other areas 45,000 litres per hectare per day
Unaccounted Water 15% of total
Fire fighting demand 1% of total demand

10.1.2 Population Forecast

The population forecast for the years 2011, 2021 and 2031 have been shown in the table below:

Capture30

10.1.3 Water Demand

Based on the above norms, the water demand for the Naya Raipur has been worked out. For Phase-wise
demand of water supply refer to table 10.3.

Capture31

10.1.4 Water resources and availability

Following surface water resources are available in the area:
− Seonath River
− Mahanadi river
− Mahanadi Canal
Seonath River being seasonal is not considered as a dependable source.
Mahanadi River and Mahanadi Main Canal have perennial flow of water and are dependable sources.
− For the first phase requirement of water, Mahanadi Main Canal intake or Annicut construction
on Mahanadi River can be considered.
− For the water requirement in the second and the third phases, new barrage near Rajim may be
the source.

10.1.5 Water Treatment Plant

The canal water or water available from the proposed barrage on the Mahanadi River, after treatment, will be supplied to the city. The treatment will include screening, sedimentation, filtration, and disinfection, the level of treatment depending on quality of available water and permissible drinking water quality standards as specified by CHPEEO or WHO. Table 10.4 gives capacity of water treatment at different phases of development. It is suggested to construct the Water Treatment Plant (WTP) in different modules. Based on availability of water, location of WTP can be arranged in such a way that the cost of distribution system would be the least. The best location for WTP considering the general topography of the area lies near upstream side (near Khandwa dam, South Side of Naya Raipur), which has a high elevation. (Refer map 10.1)

Capture32

10.1.6 Water transmission, Storage Reservoirs, and Distribution

The proposed water transmission system (raw as well as treated) is proposed to be operated for 20 hours in a day. The MBR at WTP is proposed to be of 6 hour capacity where as the sumps at individual pumping stations are proposed to be of 4 hours duration. The total system basically consists of two
parts:
1. Conveyance of raw water from the source to the proposed water treatment plants:
The raw water is proposed to be conveyed from the source to the proposed WTP through pumping
main, by locating head work and pumping station at suitable location..
2. Water from WTP after proper treatment will be supplied to different zones, for which the following
two systems are required:
• Transmission system from WTP to Various storage reservoirs
• Distribution system for various zones.
As per ascetic and landscape profile of the City it is proposed to use underground storage reservoirs and from these Under-Ground Reservoirs (UGR), Booster Pumping Stations can supply the water to distribution network. The concept of providing UGRs and BPS is a recent one and is in use in many metropolitan cities. The system has some obvious merits over the Over-head Tank (OHT) system as discussed under:
i. Economical in cost, construction in easy, requires low capital investments as compared to OHT systems.
ii. Space requirement is less as compared to OHT systems.
iii. Booster pumps can maintain uniform pressure in the distribution system.
iv. Water main need not be designed for excessive residual pressure as compared to OHT system.
v. This system is free of visual obstructions.
vi. These systems are entirely dependent on electricity. In Chhattisgarh has good power availability.However, the treated water sump in WTP is proposed at higher elevation in order to achieve water supply to various nodal points (reservoir locations) under gravity, gravity flow to the extent possible. However, where the minimum terminal pressure can not be met, combined pumping station(s) are proposed to supply treated water to the area through a pumping network. The diameter of pipe lines range between 300 mm. to 1500 mm. DI-k9 type pipes are proposed for dia upto 1000 m & MS pipes are proposed for higher dia.

10.2 Sewerage System

10.2.1 Sewage Generation

The sewage generation is approximately assumed to be 80 % of total net water supply has been considered out of which water supplied for green areas, washing streets, Horticulture, Fire fighting would cover the ground water infiltration. Refer to table 10.6 for phase-wise sewage generation in Naya
Raipur.

Capture35

Considering the topography, the project area is proposed to be divided into two drainage districts, southern zone & northern zone, each of which is proposed to have an independent sewer network, pumping station & sewage treatment plant. The overall sewerage system is proposed as follows:

Southern Zone:

This zone is proposed to cater for 60 % of the total sewage generated in the project area; one STP is to be located at the lowest spot of southern zone. The exact location shall be determined by NRDA after conducting a feasibility study.

Northern zone:

This zone is proposed to cater for 40 % of the total sewage generated in the project area, with proposed STP located in the area marked ‘zone I’as it is the lowest spot in the southern zone. An intermediate sewage pumping station is proposed in the area marked ‘planning unit II’, which would pump the sewage of about 50% of the northern zone into the trunk sewer leading to the STP. The diameter of branch sewers, trunk sewers, interceptiong sewers & outfall range between 450 mm to 1800 mm & the material proposed is RCNPIII. The rising main proposed is of DI-k9 type.

10.2.2 Sewage Pumping Stations

For sewerage system, Sewage Pumping Stations (SPS) are required where depth of excavation go beyond 6.5 m, based on the Natural contour and investigation made on general topography intermediate pumping stations are required for efficient and economical considerations.

Capture36

10.2.3 Sewage Treatment

Sewage Treatment shall be done through Sewage Treatment Plant. The treatment based on Activated Sludge Process to be adopted. Two STPs of total 155 MLD capacity are proposed for Naya Raipur. The STPs shall be developed in modules in three phases. (Refer table 10.8). One STP shall be located in the north and the other in the southern zone outside the city boundary. (Refer map 10.2).

Capture37

10.2.4 Disposal Options

The treated effluent shall be utilized in any of the following uses so as to conserve and minimize the overall water requirement viz., Irrigation, Horticulture, Ground water recharge. Three alternatives for the disposal of treated effluent are suggested as follows:
i. Kulhannala
ii. 50% down stream of Mahanadi Main canal running parallel and in the ridge line and 50% to
Kulhan nala.
iii. Other alternative is to reuse water for irrigation purposes for the downstream area so that net water requirement for irrigation canal (Mahanadi Main Canal) can be reduced. This is best possible alternative for efficient use of wastewater.
iv. Sewage after proper treatment and disinfections (not generally used for sewage treatment but required for effluent discharge Standards and DBU ‘Designated Best Use’ of Mahanadi Main Canal point of view) can be discharged to Mahanadi Main Canal. The Sewage treatment will be such that quality of water in Mahanadi Main Canal and treated sewage may not differ so much. In this case, a Pumping Station will be required to pump the treated sewage to Mahanadi Main Canal at suitable location to be decided after detail investigations.

10.3 Storm Water Drainage

Storm runoff is that portion of precipitation, which drains over ground surface. Estimation of such run off reaching storm water drainage system is therefore dependant on intensity and duration of precipitation, which again depends upon status of development of the area, soil and topographical characteristics and time required to reach the disposal points from the farthest points.
Drains are generally aligned along the valley lines between ridges. Only when natural drainage is not possible, drains are taken across the valley. The curves developed on rainfall intensity versus time of concentration showing 2-year frequency, 5-year frequency 10 year frequency and 50 year frequency in
the new capital is shown in Fig 10.1.

10.3.1 Storm Water Drainage For New Capital City

10.3.1.1 Issues and observations

Generally, the main issues on Storm Water drainage of this region are:
i. Inadequate provision of storm water drainage system.
ii. Lack of maintenance of existing drains and nallahs etc.
iii. Development process not compatible with drainage pattern.
The project area is traversed by four major streams thereby dividing the entire area into four catchment zones. All these streams are proposed to be preserved by carrying out rehabilitation/ improvements etc. All the proposed road side drains are proposed to convey the run off generated from the corresponding road and ultimately discharge the same into the corresponding nallahs / streams. Hence the proposed storm water drainage system for project area consists basically of two systems i.e.
i. Construction of Road side drains,
ii. Improvement or rehabilitation of existing Natural streams channels /nallahs.

• Road side Drains:

It is proposed to provide drains on both sides of the roads. Table 10.9 gives the length of various types of Roads suggested for New Capital city of Chhattisgarh. The storm water roads drains should as per guidelines mention in previous section. (Refer map 10.3).Rectangular concrete drains are proposed on either side of the road.

Capture40

• Improvement of natural streams:

By the development of urban area, the coefficient of runoff will increase; hence, the existing section of streams will not be sufficient to cater the increased runoff resulting form Rainfall of selected frequency of occurrence. It is suggested to rehabilitate the existing drainage channel of new capital city of Chhattisgarh. 5 years Maximum rainfall intensity should be taken for design of system, similar to cities of international standards. Additionally cross drainage works are proposed at the road crossings.

10.3.1.2 Policy

The following policies are to be adopted:
i. Develop a storm water management system that manages the quality and quantity of storm water runoff of the region avoiding any water logging in the area.
ii. Recognize the need for public ownership and operation of storm water management practices such as rainwater harvesting.
iii. Prepare and adopt erosion and sediment control guidelines of the region.

Capture41

10.3.2 Rain-Water Harvesting

Special emphasis is to be given to rainwater harvesting, in urban areas. Appropriate methods for recharging the ground water should be considered and adopted. Roof top rainwater harvesting at the individual as well as community level shall also be considered. Rain water storage, into dug up or natural lakes/ depressions, from the storm water drainage system shall be proposed, which will also help in environmental improvement as well as recreational uses.

10.3.2.1 Rain Water Harvesting for New Capital City

The principle of rainwater harvesting is to conserve and use precipitation in the same area where it occurs for greater ground water recharge and later use. The methods are site specific and may depend upon local conditions like check dams, roof top collection, aquifers recharge, storage in soil profile, creation of small basins in rural areas, contour binding, percolation tanks etc. due to urbanization in cities, the paved / impervious areas get increased resulting in reduced ground water recharge. Fig 10.2 shows common methods of Rainwater harvesting, which can be used in Naya Raipur. Rain Water Harvesting is mandatory at individual development level.

10.3.2.2 Storage Of Rainwater:

This can be achieved by following small-scale measures:
i. Recharge Pits for recharging the aquifers. These are generally 1 m wide and 2 to 3 m deep back filled with boulders, gravels and coarse sand.
ii. Trenches: Usually constructed when permeable strata are available at shallow depths. Trenches may be 0.5 m to 1 m wide and 1 to 1.5 m deep, 10 to 15 m long depending upon availability of water. These are back filled with filter material.
iii. Dug Wells: Existing dug wells can be utilized as recharge structures and water made to pass through filter media before putting into dug wells.
iv. Recharge wells: Recharge wells of 100 mm to 300 mm diameter are constructed for recharging the deeper aquifers and water is passed through filter media to avoid chock age of recharge well.
v. Roof top rain water: In big cities, roof top rainwater recharge has been recommended. Local authorities, communities need to be encouraged, can take up all these methods. Considering only 100 sqkm of area water harvesting and assuming average rainfall 1000 mm and assuming only 40 % average runoff to be retained by soil, the quantity of water that can possible be recharged may be around 40 Mcum.

Telecommunication

The Communication system is planned for both wired and wireless services for voice, data and VAS. It is proposed to have an Overlay Area Network (OAN) in the city having 4 loops to cover the total area with optical fiber connectivity with redundancy. This will provide as backbone for the modern communication and data transmission with in the city of Naya Raipur.
 
Besides, backbone infrastructures such as ducts are to be provided for the city level telecom network for the wired broadband and Value Added Services (VAS). It is also proposed to develop the passive infrastructure in the entire city for the wireless services which may cater for GSM/CDMA and other modern services such as 3G/WIMAX etc.
 
The above infrastructure is to be developed by any service provider, licensed to do so by the DOT, Govt. of India, in collaboration with NRDA.

AVAILABILITY OF WATER RESOURCES
Following surface water resources are available in the surrounding area
of Naya Raipur :
1. River Kharoon 2.River Mahanadi
River Kharoon
This was also a consideration being at almost equal distance but the
river is not perennial and already catering the need of Raipur city
supplemented by Ravishanker reservoir and hence can not be
considered as a dependable source of Water Supply for this Project.
River Mahanadi
River Mahanadi being perennial in nature is also reinforced with
water from Pairi and Sukha and has the capacity to discharge the
requisite amount of water for the proposed Naya Raipur. Hence it is
decided to construct an anicut across river mahanadi near Village
Tila, about 25 kms from the proposed capital city.
The state water utilization committee under chairmanship of the Chief  Secretary, Government of Chhattisgarh has given his consent vide letter  No. 5013/13/WRD/TS/IWS/01/D-4/Raipur dated 05/9/2006, to reserve 1.80  TMC of water, for water supply of proposed new capital of Chhattisgarh
state, for the year 2040 for the excepted population of 5.45 lakhs. Copy of
the said letter is annexured.
The Water resources department has already proposed an Anicut on  Mahanadi river for water supply to Naya Raipur city hence the
construction of an Anicut shall not be required under this project to fulfill
the intermediate need. It is proposed to construct an Anicut on upstream
side of Tila village ( i.e. Raur) which will also be constructed by
WRD for further requirement of Naya Raipur city.
PROPOSED COMPONENTS FOR WATER SUPPLY PROJECT
It is proposed to construct Intake well of 16 m Dia to be constructed on  the left bank of Mahanadi river on approximately 300 m up stream of  proposed.Anicut near village TILA( to be constructed by WRD under  state plan) with pump house to accommodate raw water pumps. The  power would be made available by constructing indoor electric sub  station of 2000 KVA near the pumping station. Then it is proposed to  convey the raw water by a raw water pumping main of 1000 mm Dia
mild steel pipeline 23.00 km in length to the conventional water
treatment plant of 52 mld capacity against a demand of 77 mld, near
village Pacheda inside the area of Naya Raipur. The clear water
pumping station with indoor electric sub station of 750 KVA shall be
erected near the water treatment plant to fulfill the demand of
intermediate stage year 2026. The treated water thus would be
conveyed to 29 nos. under ground service reservoirs located at various
sectors in the capital city by means of clear water pumping main &
clear water gravity mains. The entrepreneurs would then lift the water
for distribution purpose from UGR’s to the respective sectors that they
would be developing with complete infrastructure.
The above components are elaborated in detail as below:
Preliminary Survey  The preliminary survey has been
carried out from head works to water treatment plant and to other
required destinations including taking levels cross sections at nodal and  salient points. Details of the survey have been plotted and L-section  and lay out plan have been prepared. For network of clear water  pumping main & UGR’s the contour map of, NRDA has been referred.
No any amount has been approved under this item by CPHEEO while  appraising the water supply project.
RCC Anicut  The Anicut will be constructed by Water Resources Department near  village Tila across mahanadi river.The length of the proposed  anicut will be 11 m
and 3.60 m in height. The salient features as proposed by WRD are given in

 Transport System

 NRDA has constructed 75 KM of 4 lane / 6 lane city level road network and additional 60 KM of roadwork is under construction

The sub-regional transport system, covering NRDA area, mainly consists of the road network system. In Raipur District, apart from the two national highways, a state highway connects Raipur with Baloda Bazar. Another state highway on the southern side takes off from NH-43 at Abhanpur and connects to Rajim. From Rajim, a Major District Road (MDR) connects to Mahasamund on NH-6. The Master Plan for State Roads Development has proposed upgradation of Nawapara (on Raipur-Rajim SH) – Arang (on NH-6) road as a MDR. The Arang-Nawapara-Abhanpur road link connects NH-6 and NH-43 and will function as a bypass road for Naya Raipur. As part of sub-regional plan it is proposed to connect all the villages by an all-weather village road so that they are all connected to a higher order road either directly or through another village settlement.

9.3.3 Naya Raipur City Transport System

Intra-city transport system requires huge investment for their development, maintenance, operation and management. In terms of land use, ‘transportation’ accounts for 12.55 % (1005.77 Ha) of the gross area of Naya Raipur.

9.3.3.1 Road Network

The Road Network, which is the most important component of the city transport system, integrates three conceptual forms – linear, cruciform and grid thus providing a basic skeleton around which various activities are dispersed and interlinked. Naya Raipur road network extends over a total length of 117.86
km and accounts for 843.97 ha of land.

1. Hierarchy

The envisaged hierarchy of roads, by right of way is as under (Refer map 9.2):
 City Arterial Roads (100 m/60 m)
 Intra-Sectoral Roads (24 m/18 m /12 m)

2. Road Link Identification

A unique numbering system is adopted to identify the links and nodes (intersections) of the road network system. All north-south roads are given alphabetical identification like AA, BB, CC roads, etc, starting from the west moving towards the east. All east west roads are given numbers like 11, 22, 33 etc. starting from the south and moving towards the north. With this all nodes (intersections) get an alpha-numeric identification like A1, B2, K13 etc. and the links in turn get identified by the node numbers at its ends like A1-A2, H3-H5, etc. (Refer map 9.3) for link and node identification.

3. Development Phasing

The road network is proposed to be developed in three phases as stated below:

Phase I

The phase I shall establish the basic core network thus initiating the further development. The sequence of development would be generally from the basic core towards all directions with adjustment of priority developments (Refer map 17.2).

Phase II & III

The core network shall be further extended in all directions, as per requirement to complete the network.

1. Road Cross Sections

The road cross-sections provide ways for general traffic, exclusive ways for public mass transport (bus) system, pedestrian paths and ways, cycle tracks, utility corridors and green strip. The phase I cross – section details shall be as indicated in drawing 9.1 and 9.2. The major roads shall be free of service lanes so that no abutting property/activity gets a direct access from the main road. An internal road system linked to the main roads at defined locations shall provide access to all the activities

2. Pavement

It is recommended that in the initial period, flexible pavement be constructed to allow for consolidation and settling of base. IRC Guidelines for the Design of Flexible Pavement (IRC:37-2001) and other relevant codes shall be followed. Cement concrete pavements may be constructed in the later phases
along roads that carry higher volumes of traffic.

3. Intersections

All intersections shall be designed and developed as roundabouts. The diameter of the central rotary should be more than the carriageway widths of links meeting at the intersection. The roundabouts need to be landscaped. Different thematic motifs could be adopted for the different roundabouts representing the wide variety of flora and fauna of the state of Chhattisgarh. Maintenance of roundabouts could be enabled through participation by industrial and trade houses.

4. Geometric Design of Links and Nodes

The geometric design of all links and nodes to be carried out in accordance with the manuals and guidelines and in conformity with standards and specifications prescribed by the authorities and professional bodies like MoUD / MoRTH, GoI, Indian Roads Congress, Institute of Town Planners (India), Institute of Urban Transport (India), Bureau of Indian Standards.

5. Utility Lines

All utility lines (electricity, telephone, cable, water supply, sewerage, drainage, etc.) shall be laid below ground level. Ducts shall be provided along and across the roads to lay the utility lines. Major trunk (water/sewerage) lines are to be laid along the utility corridor.

6. Street Lighting

Street lighting needs to be of high quality. The light poles and other fixtures need to be aesthetically designed. Sodium vapour lights along city network system shall be provided. High intensity, high mast lights to be installed at intersections, bus stops and major pedestrian movement areas. The specifications
and guidelines prescribed by the Bureau of Indian Standards and/or other relevant Professional Institute to be followed.

Capture22

7. Drainage

Road drainage needs to be given close attention to enable quick runoff of surface water and prevent water logging. The road level shall be kept at least 0.5 to 1.0 m above the observed high flood level (HFL) at any location. The road drainage system of Naya Raipur needs shall be planned and designed as an integral part of the road network system planning and design. The Guidelines on Urban Drainage, IRC: SP-50 shall be followed.

8. Fencing

To prevent unauthorized ribbon development along and control access to the city peripheral roads, it is recommended that fencing along the outer edge of the road right of way may be carried out. Also, the design of longitudinal drain along the edge of the roads may be availed to act as a barrier for such development/access.

9. Traffic Signs and Lane Markings

Traffic signs of different types, as prescribed in IRC: 67-2001 to be installed along the road network. Overhead gantry signs to be provided at suitable locations to guide traffic. Lane markings along the roads, at intersections and at all pedestrian crossings to be provided as per specifications and guidelines in IRC: 35-1997.

10. Pedestrian Paths

Pedestrians shall be given priority attention in detailing the transport system. The components include:
 Footpaths
 Pedestrian ways and corridor
 Pedestrian plazas
 Other facilities

Footpaths

Well-lit and smooth surfaced footpaths, of minimum 2.0 m width, on both sides of all roads shall be provided for. Interlocking tiles provide opportunity to create interesting and attractive designs.

Pedestrian ways

Pedestrian ways are proposed along the ‘Green strip cum Utility corridor’ along the right of way of the major roads (100 m/60m). This shall be incorporated as part of the proposed landscape plan of the green strip.

Pedestrian Corridor

A major ‘Pedestrian Corridor’ has been proposed from the southern end to the northern end along the‘Public facilities cum Green Corridor’ (Refer map 9.4). This corridor passes through the central park, the cultural complex and the CBD. It needs to be sensitively designed to make it attractive and safe. Its width may vary from 3m – 5 m and could be combined with cycle tracks. The proposed pedestrian corridor primarily runs along the green strips. However it needs to cross the major roads at a few locations. In the initial phases these crossings could be at grade with clear markings, adequate signage and good lighting. However in the long run, they need to be grade separated with convenience accorded to the pedestrians.

Capture23

Capture24

The detailed layout of residential sectors, envisages the concept of axial green strips, interlinking with the green strips of adjoining sectors that result in a large number of continuous green paths along the length and breadth of Naya Raipur. Pedestrian paths shall be included as a part of the landscape plan for
these green strips

Pedestrian Plazas

In the preparation of detail plans of activity areas like CBD, Govt office Complex, Institutional areas, etc, pedestrian plazas shall be incorporated as part of the integrated design.

11. Cycle Tracks

Cycle Tracks, of minimum 3 m width, are to be included as part of the integrated design of the green and pedestrian corridors and ways.

12. Hoardings

Hoardings along the roads, which distract the attention of drivers and degrade the aesthetic quality, shall be strictly prohibited. At certain locations specially designed wall spaces may be provided for advertisement/information. Bus shelters shall be designed to provide for controlled advertisement space.

13. Public Conveniences and Dhalaos

Public conveniences and Dhalaos are provided generally in the ROW of roads. Apart from the need for good design and proper maintenance, they can also be major source of income generation by providing space for commercial advertisement. They shall be so located as to ensure that they do not adversely affect the geometrics of road system in terms of sight distance, obstruction, etc.

9.4 Public Mass Transport System

The economy of Naya Raipur is envisaged to be high. Proportion of middle and high income groups is expected to be higher than those observed in other cities. Hence motor vehicle ownership by households is estimated to be high, possibly nearer to 2 per household in the long range. The road network system is
planned and designed to enable efficient and safe movement of motorized traffic. However it is prudent to minimize usage of personalized modes, particularly for mandatory trips like work and education, by providing a highly attractive, convenient and efficient public mass transport system. The linear form of the city is conducive to public mass transport (LRTS). The grid iron form provides flexibility in provision of services (Buses & ITPs). It is important that a high quality public mass transport service, be operated from the earlier stages in order to mould the travel behaviour of the residents of Naya Raipur in favour of public transport.
The public mass transport of Naya Raipur would include:
A. Bus system (common carrier)
B. IPT modes and
C. Rail based LRT System

A. The Bus System

The bus system is the most important component of the proposed inter-modal city public transport system. In order to provide a high frequency service operation, the use of mini buses is recommended. The average load factor shall be limited to 0.7 by operating more buses for a high degree of comfort. CNG based or preferably, battery operated buses are recommended in order to maintain the environmental quality of the city.

1. Bus Depots

A requirement of 160 to 180 buses is estimated for the new city. Two depots, each of 2.5 Ha, are proposed in the service industry area.

2. Bus Terminals

Bus terminals are important to facilitate convenient interchange amongst modes and passengers. They are also prominent elements of the urbanscape providing orientation and identity. They need to be designed sensitively and managed efficiently.

i. Inter-City Bus Terminal

An inter-city bus terminal is proposed at the ‘Transport Hub’ area, on the northern side that helps integrate the rail station, intra-city bus terminal and IPT modes. An extent of 2 Ha for the terminal has been reserved for the same.

ii. Intra-city Bus Terminals

A total number of 5 nodal intra-city bus terminals have been proposed at the following locations –
1. Transport Hub in the north
2. Railway Station/University Area in
the south
3. CBD (Central node)
4. Software Technology
Park/Exhibition Grounds in the west
5. Government offices area in the east

An area of 1 Ha has been reserved for intra-city bus terminals at each of these locations. The north, central and south nodal terminals shall be integrated with the proposed LRT system. These nodal terminals shall be planned and developed as multi-use complexes and their development and management shall be entrusted to the private sector, through BOT route, under the PPP model.

Capture25

iii. Sub-Terminals

In all activity areas, the Local Area Plans (LAPs) shall make suitable provision for terminal facilities for the buses serving these areas.

3. Bus Routes

The flexible road network provides a variety of options for planning the bus route system. The nodes and residential as well as other activity areas shall have a ‘hub and spoke’ relationship where the nodes provide the direct services and the other activity areas provide subsidiary services to each other. The grid network enables planning of route services on random transfer basis.

4. Bus Ways

Exclusive bus ways shall be developed in a phased manner along the major road corridors (100m/60mrow).

5. Bus Stops

Bus stops need to be located providing easy access to a maximum number of people and activities. Bus stops along the proposed LRTS corridor to be located such that they integrate with the future LRTS stations.

6. Bus Recess/Bays

During the early phases when buses operate in mixed traffic, bus recess/bays shall be provided as per
standard design.

7. Bus Shelters

Bus Shelters are important to provide convenience and shelter to bus passengers. They are also conspicuous elements in the streetscape and need to be designed and maintained well. The bus shelter designs need to be modern and also to incorporate the cultural themes and motifs of Chhattisgarh. Bus stops also need to include other facilities like telephone booth, drinking water, etc. Bus stops could be a source of resource generation to the operating system by incorporating space for commercial advertisement. With a common design, they may also be constructed and maintained by private parties under concession.

B. Intermediate Public Transport

Intermediate Public Transport modes are an important component of an urban public transport system. They bring in private sector initiative, investments and management with least cost to the public exchequer. In a city like Naya Raipur a large number of floating population for business and other purpose is expected. It is prudent to facilitate entry and operation of a good, technologically modern, energy efficient and environment friendly mode(s) to provide the much needed service. To facilitate the service, physical space for parking and other needs of the operators are to be provided as part of the Local Area Plans.

C. Rail Transit System,/

A rail based urban transit system, to be part of the Public Mass Transport System of Naya Raipur, has been proposed. It runs along the central axial corridor between the two inter-city rail station complexes (Refer map 9.5). The alignment interlinks a large number of activity areas with the residential areas. The system could be Light Rail Transit (LRTS) or mono-rail, to be selected based on detailed studies. The corridor length is about 15.5 km and shall have 12 intermediate stations. The system is proposed to run on elevated way. It will run underground for a short stretch to cross the City Park and 100 m east west central vista road. The rail based system plays an important role in enhancing the image of the city and providing high degree of accessibility and high quality service to the people. It would also help in promoting safety and enhancing environment quality of the city. The system could be made financially viable through a well designed public private partnership package. The city should raise the capital cost through a charge on land/floor space development. The
system would enhance the realty values and measures for value capture to be set in from the start itself. Given careful planning, design and operation with financial prudence and sound management, the urban rail based public mass transport systems could be viable. Naya Raipur is expected to be a technologically modern, world-class city. It is important that the public mass transport of the city is modern, efficient and attractive.

D. Parking

Demand for parking of private, public and commercial modes will be high in Naya Raipur and adequate provision shall be made to cater to the parking needs. A comprehensive Parking Policy needs to be formulated to address this demand. The components would include:
 Parking norms
 Space standards
 Pricing
 Institutional arrangements
Parking Norms and Space Standards
Please refer section 18.6.2.2.

Pricing

A policy of pricing all parking areas anywhere in the town needs to be adopted from the very beginning. Differential pricing, by use area and by hour of day, needs to be included. The objective of pricing is to regulate demand. However this policy needs to be supplemented by a good public transport service.

Municipalisation of Parking Areas

The concept of municipalisation of parking areas needs to be adopted. In CBD and other commercial areas major part of parking should be under public control and management. Compounding fee, in lieu of parking space, to be charged and public off street parking space developed out of the income generated.

Institutional Arrangements

An institutional arrangement needs to be established for the Management (Operation and maintenance) of parking spaces. It could be either a departmental unit, a special parking agency or outsourced to a private agency.

General Parking Areas

Generation of parking spaces in individual building units through building bylaws needs to be supplemented extensively by generation of public parking spaces in development areas. Special provisions shall be incorporated in the zoning regulations to mandate generation of parking areas as part of Area Development Plans. Area and use based norms to be framed in addition to floor space based norms. Parking solutions shall be more land area based rather than building space based.

Equitable access to all

The transport system plan aspires to provide equal and safe mobility to all. Hence, in accordance with this goal, the design of all roads and transport facilities shall be non-discriminative with respect to physically challenged persons. They shall be in accordance with “The Persons with Disabilities (Equal Opportunities, Protection of Rights and Full Participation) Act, 1995 (No 1 of 1996)”, rules framed there under and other acts, rules and guidelines as relevant.

9.5 Phasing and Cost Estimation

10.5 Power

Naya Raipur city for 5.6 lakh population is proposed to be developed in three phases. The estimated power requirement by the completion of phase III will be 565 MVA. The calculation is based on :
 Average Power Demand of 2 KW per household
 Rate of growth of Power demand @ 6.49 % per annum
 Power Factor – 0.9
 Plant/Substation Load Factor – 0.8
 Diversity Factor – 0.6

10.5.1 Development of Power Supply in Phase-I

The estimated power requirement in this phase will be 95 MVA. The power demand can be met by importing power at 33kV voltage level from the nearby sources. 5 nos. 33/11kV substations of capacity 20MVA are to be built in or around the town.

10.5.2 Development of Power Supply in Phase-II

The estimated power requirement for this phase will be 130 MVA. The demand of the already developed Phase-I of the city will increase by 61MVA by the end of completion of Phase-II. The total increase of load by the end of completion Phase-II will be 191 MVA. Total load at the end of Phase-II development will be 286MVA.
It is proposed to build a dedicated 132/33 kV grid substation of capacity 200MVA for the proposed city. Power at 132 kV from National Grid/Chhattisgarh Electricity Board grid will be received at the grid substation and stepped down to 33kV which will further be transmitted to various Sector substations (33/11 kV). 10 number of 33/11kV substations in addition to the already built 5 number in Phase –I will have to be built to cater this increase of load.

10.5.3 Development of Power Supply in Phase-III

The estimated power requirement in this phase will be 155 MVA. The demand of the already developed Phase-I and Phase -II of the city will increase by 124MVA by the end of completion of Phase-III. The total increase of load by the end of completion Phase-III will be 279 MVA. Total load at the end of Phase-III development will be 565MVA.
14 numbers of 33/11kV substations in addition to the already built 15 numbers in Phase –I and Phase-II will have to be built to cater this increase of load.
Therefore the total estimated requirement for the completely developed city will be 565 MVA. Two more 132/33kV grid substation in addition to the one already built Phase-II will have to be built in this Phase of development.

10.5.5 General Recommendations for setting up modern Electrical Power Transmission and Distribution system

The following steps are recommended for improvement in Transmission and Distribution of Power Supply.
i. Power supply for up to 33 kV voltage should be taken through underground distribution system. The cables can be taken through underground duct or simply buried in the ground.
ii. The Proposed Grid stations should preferably be built around outskirts of the city. Power supply at 132kV or above voltage level can be taken through overhead system.
iii. To ensure minimum interruption of Power Supply, 11kV underground distribution system can be connected in Ring Main. It will ensure alternate source of power supply for all substations connected to the Ring Main.
iv. Wherever it is necessary to use overhead transmission (Outside city limit), LT Arial Bunch cables can be used to check power theft.
v. 11/0.433kV substations can be indoor or outdoor type.
vi. Wherever there is space constraints in congested areas, Modern compact packaged outdoor
substations can be used. This type of modern outdoor substation contains Transformer, RMU,
Capacitor and all the Switchgear arrangement in a single compartment. Space requirement for this
type of substation is only 5m x 5m x 4m.
vii. The main receiving stations (Grid Stations) should have the SCADA (Supervisory Control and Data Acquisition) facility to ensure on line monitoring and control of power supply. All substations and distribution stations will be interconnected with controlling stations by using modern methods e.g. Fibre optics. viii.As far as the usage of power is concerned, it is proposed to use energy efficient electrical light fittings and lamps e.g. low power ballasts, low consumption high power luminaries, lux level limiters and timers for street lighting etc. Non-conventional source of energy e.g. solar heaters are
proposed for heating. High masts will be used at road junctions, stadiums, transport hubs, parks and for area lighting. All consumers domestic, commercial, government organisations will be metered.
