• Haryana Urban Development Authority (HUDA) new city of Gurgaon.

• While Haryana State Industrial and Infrastructure Development Corporation (HSIIDC), Public Limited Company owned by the Government of Haryana – in Manesar.

Waste water

Recycled water

Fresh source of water

Untreated water

Now • GMDA (Gurugram Metropolitan Development Authority) supplies in GMUC area • HSIIDC is responsible for industrial demand of water

Guidelines Water Consumption scenerios in Gurugram According to GMDA : • •

• • • • • • •

Current demand for water in the city - 400 MLD per day Expected to increase four times by 2031 — 1,650 MLD (increase population and construction activities in GMUC area) Only 30% out of 400 MLD is used for Kitchen purpose which requires potable water RO wastes three litres of water for every litre that it purifies Only 7 per cent of the total waste water is being recycled (as of 2011) 25% of the demand through recycled water by 2031 is planned Recycled water usage for construction activities –compulsion by HUDA from 2014 to 2018, the groundwater table fell by 3 metres in Gurugram city.

Current Capacity of water treatment plant is 126 MGD.

BACKGROUND :

MGD)

•The prospective total water demand of Gurugram Development Plan area excluding Manesar is projected .

•Water distribution in Gurugram is divided into spread across sectors 1 to 115.

•Zone-I to III refers to sectors 1 to 57 and is supplied to VI refers to new sectors 58 to 80 and Zone-VII This area of Zone-IV-VI covering sectors 58 to located at distance of 22-25 km from WTP Chandu Budhera 25-30 m.

•One intermediate boosting station on second water supply with sufficient pressure.

Gurugram Manesar Urban Complex–2031A.D. (GMUC projected as 368 million gallons per day (MGD) into eight planning zones i.e. Zone-I to Zone-VI supplied with water from WTP Basai while Zone-IV VII to VIII refers to new sectors 81 to 115. to 67, 68 to 80 and 37C, 37D (thirty one sectors) Chandu Budhera and having elevation difference rising main in Sector-72 is required to provide water supply with sufficient pressure.

MAP -1

MAP - 2

Inferences : 1. MAP – 1 denotes the water distribution across different sectors, further divided into zones, where few zones such as Zone 1-3 and Zone 9 covers larger land area, thereby covering good network of water distribution .

2. Map -2 locates the different water supply systems existing in Gurugram. Water Treatment plants are : HUDA/ Basai WTP and Chandu Budhera/ 66 MGD WTP. HUDA WTP being located in northern peripehral road, supplying water to major sectors. Gurugram has two boosting stations and tubewell supply areas being 4 in number near Sihi villiage.

3. From both the maps, we infer that, though Gurugram has good water supply in major portions of the city specially in the North and NEastern part , supply network needs to be framed out for sectors in New Gurugram area.

ANALYSING PERFOMANCE • • •

Domestic water consumption is 200 per day (MLD).

This caters to per capita average of 89L a day for an estimated population - 18 lakhs (as per CMP)

•

Per capita per day = Domestic water consumption per day population

•

Per capita per day = 200 MLD (200 X 10,00,000 Litres) 18 Lakh

•

Per capita per day = 111.1 lpcd

Recycling of waste water in Gurugram

There is no facility to recycle the waste water and supply it for agricultural purposes. Future water demand for Gurugram city cannot be satisfied, unless large scale planned recycling of wastewater is carried out by establishing such facility. Worldwide several cities have developed water recycling facilities to utilize the waste water resources. In such recycling plans, all the treatment facilities are generated within the cities and all water quality parameters are analyzed for wastewater recycling. The major aim of such recycling plants is to create and nurture the water cycle and ensure the constant supply of water for irrigational and industrial purposes.

Conclusion

According to LEED

Hence, per capita water consumption of Gurugram is less than the standards of 135 LPCD. And with increase in population and demand of water with limited source of fresh water, it is necessary to have an integrated water network. Potable water should only be used for drinking and cooking and for other activities like flushing, washing, etc which accounts to 70% of potable water usage should be replaced by recycled water, therefore Gurugram needs to be focused more on waste water management.

The Water Performance Score rates the city or community on per capita domestic water consumption in the city compared to the per capita domestic water consumption by comparable cities and communities. Lesser the amount of per capita domestic water consumption, the higher the score will be.

•Water supply and demand gap is invariably satisfying, though with demand of 135 LPCD and supply of potable water being 111 LPCD , where we do have a margin of requirement of 24 LPD in Gurgaon.

• The GMDA supplies water in regular hours in many sectors of Gurgaon, one being in 9-11 am in the morning and 7-9pm in the late evening.

• Dependency of water on tanks : Most of the Northern and eastern part of Gurugram is dependent largely on water tanks supply water from GMDA. •The gap between official demand and supply is estimated to be about 42 per cent in coming years.
