Power Scenario in Delhi
The development of land in Delhi is governed by Master plan prepared by Delhi Development Authority (DDA). In addition, other agencies like MCD, CPWD, PWD,DSIIDC, NDMC and HUDCO also take up the development of land of residential, commercial and industrial purposes. DVB’s (Delhi Vidyut Board) development activities are dependent on the programmes and policies of such local bodies , since arrangements have to be made for meeting the requirements of such developments, as also the natural increase in demand for power in the whole of the National Capital Territory of Delhi, since DVB is the licensee for power supply in Delhi.
Power Demand of Industrial Complex
DVB has made following norms for load demand of industrial units of different size of plots in Mangolpuri Industrial Area.
|S. No.||Plotted Area||Load Norms|
|1.||100 sq. yds.||18 HP|
|2.||150 sq. yds.||20 HP|
|3.||200 sq. yds.||22.6 HP|
|4.||400 sq. yds.||35 HP|
|5.||600 sq. yds.||40 HP|
|6.||1/4 Acre||45 HP|
|7.||1/2 Acre||60 HP|
|8.||1 Acre||70 HP|
|9.||2 Acre||115 HP|
|Method of Electrification
The electrification of the project will be done by DSIIDC by awarding to a private/Public sector agency on BOOT basis. The entire cost of providing power will be Charged to the project and cost recovered from allottees.
The propose 755 Ha. of industrial complex at Bawana and Holambi Kalan , is surrounded by 100, 80, and 60 m wide Master Plan road. In addition to the above roads, there will be roads sizes 40,24, 18, 15 and 12 m. Besides these roads, there is provision of 4m wide cycle track with 7m wide green belt on either side in various sectores in the layout plan.
Ministry of Surface Transport (MOST) and CPWD specifications are proposed to be adopted. Scheme estimates have been prepared and based on this estimate, it has been assessed that the average embankment height for formation of roads will be varying between 0.5 to 1.0 m.
Delhi Water Supply ScenarioSources of Water of Delhi Jal Board
The original source of water for Delhi has been river Jamuna but because of extensive use of river water for irrigation purposes by Haryana and U.P., availabilioty of water for Delhi from Jamuna river has been restricted. Delhi has become totally dependent on neighbouring states for its requirement of water for drinking as well as other uses.
Delhi Jal Board is equipped at present to produce 580 MGD of potable water from the various Water Treatments Plants, Ranney Wells and Tube Wells as per details below:
|S. No.||Name of the Plant||Capacity (MGD)||Source|
|3.||Haiderpur||200||Western Jamuna Canel|
|4.||Bhagirathi||100||Through Murad Nagar offtake from upper Ganga Canal, U.P. Govt.|
|5.||Ranney wells and Tube wells||70||Under ground water|
| ||Total||580|| |
Water Demand for the Bawana industrial Complex
The water supply scheme for Bawana Industrial Complex having a scheme area of 755 has been worked out considering water demand for industries, water sources, topography of area, etc.
The total water demand for the Industrial complex is based on the number of industries, commercial centres, public and semi-public utilities / facilities, green belt etc. Calculation of water demand is based on:
- Total land acquired by DSIIDC at Bawana and Holambi Kalan
- Structural plan area which excludes the roads and its adjoining green belts
Norms of Water Supply
Water Demand for the Industrial Complex
a) As Per Delhi Master Plan 2001 and Water Supply Manual :
The water requirement norms are as follows
|Industrial, commercial, Public and Semi-Public|
(Industrial area exclusive of the green belt and residential)
|Residential Complex||150 lt/capia./day|
|Green Belt||67,000 lt./ha/day|
|Fire Fighting||1% of total water demand|
The total water demand is as follows
|Description||Capacity in MLD|
The water supply for the industrial complex is proposed to be restricted to a rate of 5 litres/ sq. m. For any additional water requirement for the industries units the unit owners will have to make necessary arrangement individuallly.
Water Supply Source
There are three sources of water supply for the complex :
From Western Jamuna Canal
The Western Jamuna Canal,
which runs on the northern side of the Project area supplies water to Delhi. Permission to get
water supply from this Source, will have to be negotiated by the Government of Delhi with the
Govt. of Haryana and this may take a long time for finalisation.
From Delhi Jal Board
Again the DJB is not able to supply the full requirement of Delhi. This source will also be on a long term basis only.
From Ground Water Sources
The only immediate option is to tab the underground sources by drilling bore-wells and extract ground water. Provision has been made in the estimate for drilling bore-wells and treat the water by having a Water Treatment Plant.
Reliance has been placed on borewells for the entire requirement of water for the Project.
The total scheme area of the proposed Industrial Complex is 755 Ha, inclusive of structural plan roads and green belt. However, for the design of sewerage system, the total area for the industries is considered as 564 Ha, which excludes the structural plan roads and its adjoining green belt.
The total water supply demand for the proposed industrial area is 28 MLD of which 25 MLD of water shall be supplied for industrial, residential and commercial units and the balance 3 MLD of water required for horticulture and fire water requirement shall be provided by recycling the treated effluent. The basis for the water demand of 28 MLD is given below:
|Total water demend for the industrial area|
( exclusive of structural plan green belts and circulation)
|Amount of waste water generated from the industrial |
and commercial units ( 80% of the total water supplied)
|Total length of the sewer||275000 m (approx.)|
|Total no. of manholes ( @ 30 m c/c )||9167|
|Infiltration in the sewers||2 MLD|
|Total quantity of waste water generated due to|
industrial and commercial units and due to sub soil infiltration
Keeping in view the flat terrain of the industrial area, pumping of sewage through intermediate pumping stations to the site of common effluent treatment plant is considered necessary. With a view to restrict the maximum depth of waste water line, preliminary designs have been worked out with pumping stations.
The waste from Bawana area shall be collected from the individual industrial and commercial units at pumping stations located in the sectors II and IV and for Holambi Kalan area at pumping station located at sector V through pipes having sizes varying from 250 mm to 600 mm. The minimum surface cushion for the pipes provided shall be 1.0 meter below the existing ground level. Manholes at every 30 m centre to centre shall be provided fro proper maintenance of the waste water lines.
Storm Water Management
The proposed Industrial Area is spread over a total scheme area of 7555 HA. This total area has been divided into two parts by Western Jamuna Canel (WJC).
A storm water drain, Bawana Escape is passing through the Industrial Area. The drain originates from villages Harewali and Daryapur. The drain is an escape provided to WJC by Haryana Irrigation Department in order to maintain water level in the WJC.
The area South East of western Jamuna Canal is served by two drains namely Bawana Escape and Ghogna drain. The total area under the command of these two drains combined together and the expected storm water run off are as under:
|Description of the area||Discharge|
| Area North West of WJC||19.00 cumecs|
|Area under the command of Ghoghna Drain|
(1256.15 Ha, @ 0.11 cumecs/sq.km)
|Area under residential / industrial Ghoghna Drain|
(510 Ha, @ 3.5 cumecs/sq.km)
|Artea under lake and ESS|
( 175 Ha, @ 0.11 cumecs/ sq.km )
|Total Discharge||38.40 cumecs|
The areas above, which are primarily rural areas are being presently served by Bawana Escape having a bed width of 4.6 m and a water depth of 1.5 m.
Extensive desk research and industrial survey have been conducted for assessing the different kinds of solid waste that are expected to be generated from various industrial, commercial and human activities. The methodology adopted for assessment is as follows :
Records Review :The concerned Government departments viz. MCD, NDMC, MOEF, DPCC, MNES, HUDCO and CPCB were contracted to collect relevant information related to solid waste generation , collection, handling, transportation and disposal practices adopted by such type of industrial estates in India.
Survey of Industries :To quantity and characterise the solid waste expected to be generated by the estate, around four hundred industries were visited out of which two hundred and forty industries responsed. Out of these eighty-one were found responsive. The industrial survey was conducted in arpound Delhi and the information was collected through a questionnaire for which response was sought.
Solid Waste Generated From Human and Commercial Activities
|S.No.||Description||Population||Total waste generation @ 0.4 Kg/capita/day
|3.||Utilities / Facilities||11,887||4754.8|
|4.||Commercial, public & Semi- public||21,386||8554.4|
Water demand for fire fighting purposes is calculated based on the asumption that 1 unit of 250 sq.m. is on fire and 5 lpm water is required for controlling the fire for a period of 3 hours.
Area under fire = 250 sq.m. Area under influence of fire= 3 adjacent units of 250 sq.m.
Water requirement = 250*4*5*180=900000 litres
Total water storage 900,000 litres
Capacities of each underground fire water storage tanks provided :
- Sector - I = 2,80,000 litres
- Sector - II = 2,80,000 litres
- Sector - III = 2,80,000 litres
- Sector - IV = 2,00,000 litres
- Sector - V = 2,00,000 litres
Total storage capacity provided is 14,00,000 litres which is adequate to provide sufficent quantity of water in the event of fire breakout.
Fire Fighting Facilities - Follow up Action On Proposed Project / sector Plans
Pedestrain pathway adjoining parking and unloading area within the cluster - should be widened and ahall be motorable to facilitate approach to the building in case of an emergency.
The ESS (Electric Substations ) which are actually Switch / Panel Board Stations shall be termed as substations. The fire service does not allow substation close by to the hazards.
- All pedistrain pathways within the clusters shall be at least 6m wide and motorable.
- It is preferable to have basement sprinkler.
It is advised that DSIIDC while sanctioning, architecture plans of industry ensure that there are two exits from a basement.
All partition walls between plots shall be at least "9" thick brick masonry and plastered on both sides.
At least one Firewater reservoir of adequate capacity to be provided for each sector besides one in each of the proposed fire station.
Horticulture & Landscapping
The development of horticulture activities will aim at improving the quality of life. This is based on understand the significant releationship between people, cities, open space and urban form. The following have been kept in mind while designing the Horticulture and Landscaping Schemes :
- Emphasis human development, social welfare and community integration
People should have access to activities and facilities, regardless of intrest, age, sex, income, culture, background, housing environment or handicap.
Public recreation should be coordinated with other public services such as education, health and transportation.
- Facilities should be adaptable to meet future requirements
- Facilities and programs should be financially feasible at all stages of development.
Facilities should make the most efficient use of land and should provide convenience, health, safety, pleasure, energy, energy conservation, etc.
