Solar Energy based Dual Pump Mini Piped Water Supply Schemes 

These schemes are implemented since the year 2009-10 as per the Govt. GR No. Grapapu-5310/ Pra. Kra.217/ Papu-15, Dated 21/08/2010 & revised Govt. GR NO Grapapu-5310/ Pra. Kra.217/ Papu -15, Dated 29/12/2011 & Corrigendum Dated 17/10/2012.In this scheme, 1 HP solar submersible pump is fitted along with the existing hand pump in the bore well having minimum yield 2000 liters per hour.The water is collected in the 5000 liters capacity storage tank & it is then supplied to 30-40  households through tap water connections / public stand posts. The rain water harvesting structure for the bore well recharge is also included in the scheme. This scheme has maximum expenditure limit of Rs.5.10 Lakhs each. Since the year 2009-10 to 2016-17, the total 3935 No. of schemes are completed so far.  

                               

 Use Of Solar Energy For Dual Pump Scheme A Boon For Women

More than 75 percent of India’s population lives in rural areas and 85 percent of the rural water supply is ground water based. Hence bore wells with India Mark II hand pumps are the most important elements of rural water supply. However, it is also a well-known fact that during summer when the water levels deplete, accessing water becomes much more difficult. If pumping levels deplete below the lifting capacity of the hand pump, 36 meters, it stops working and water scarcity is declared in that area despite water being present in the bore well. In rural areas, generally, women have to face all these problems. The patriarchal society holds women responsible for such routine tasks hence these women crave for a tap water supply.The Groundwater Surveys and Development Agency (GSDA) of the Water Supply and Sanitation Department of the Government of Maharashtra realized the plight of rural women and came forward with an innovative solution called dual Pump Scheme. In this scheme, a single phase 1 HP powered submersible pump is installed in the existing high yielding bore well having a hand pump. Pumped water is stored in a 5,000-litre tank and water supply is provided to each house through a tap. Roof top rainwater harvesting is mandatory to make the scheme sustainable. Hence, water supply is restored by either one of the pumps.The scheme comprises five major components: i) high yielding bore well/tube well (yield not less than 2,000 liters per hour); ii) installation of solar energy powered submersible pump with required photovoltaic panels. iii) HDPE storage tank of 5,000 liter capacity and arrangement for elevating it to 3-meter height to give sufficient head for the distribution system; iv) distribution system for 30 houses with individual tap connections; and v) rainwater harvesting structure.As on today 1860 Solar energy based dual pump piped water supply schemes have been completed in small habitations in the state under the technical guidance of GSDA.

The scheme comprises five major components

 i) high yielding bore well/tube well (yield not less than 2,000 liters per hour);

ii)  Installation of solar energy powered submersible pump with required photovoltaic panels.

iii) HDPE storage tank of 5,000 liter capacity and arrangement for elevating it to 3-meter height to give sufficient head for the distribution system;

iv)  Steel structure - 3 Mar. Height for mounting HDPE Water Tank.

v)   Distribution system for 30 houses with individual tap connections

            1.Name of the village-  Pavimuranda, Taluka- Chamorshi, District- Gadchiroli

Pavimuranda is a tribal and Naxal affected village, located in Chamorshi Tahsil of Gadchiroli District.The village is located about 42 Kms away from the district headquarter Gadchiroli. It is surrounded by the forest,

Households-50 households

Population- 630 souls.

Community- Tribal (S.T.). 

Existing Water resources

 There are 3 dug wells and 4 hand pumps for drinking water supply in the village. Dug wells within the vicinity of the village have no water in summer, and source well is located at about 400 meters away from the locality. Fetching water from this distant source was the tremendous laborious and time-consuming task for the villagers especially for women, in the summer season. There was no piped water supply scheme in the village.Under such circumstances solar based dual pump water supply scheme was executed  in the year 2012 under National Rural Drinking Water Project (NRDWP)   Pavimuranda is a tribal and naxal affected village, located in Chamorshi Tahsil of Gadchiroli District.

Scheme Details

Bore well is fitted with 1 HP (900 WATT) solar photovoltaic submersible pump along with existing India Mark II  hand pump Solar panels of 675 watt are provided with the system. These panels can be easily cleaned by local peoples. Scheme consists of 5000 liters HDDE water storage tank mounted on 3 meter high fabricated steel structure. Distribution system with four public stand posts is provided in the village. Household connections are also provided for 30 houses. Water is made available round the clock, i.e. continuous during day time by solar pumps & from storage tank at night. Hand pump is available as secondary device. The cost of the scheme is Rs.5.10 lakhs. Popular contribution is 5 percent as per Govt. norms.The villagers are very happy with the scheme and also with reduced time and labour of working women

Households-246 households (SC HHS- 58, ST HHS- 39)

Population- 1364 souls.

Community- S.C.& Tribal (S.T.).

 Existing Water resources

There are 11 hand pumps for drinking water supply in the village. Dug wells in the vicinity of village are of seasonal nature and runs dry in summer. Water table in bore wells fitted with hand pumps depleted in summer and thus requires tremendous physical efforts to operate the hand pump. Fetching water in summer is a hectic for villagers particularly for women. There was no piped water supply scheme in the village.Under such circumstances solar based dual pump water supply scheme was executed here on  11/04 2012 under National Rural Drinking Water Project (NRDWP)

Technical support provided and  funds are made available by Govt. of Maharashtra though Ground Water Survey and Development Agency. Villagers are satisfied & facilitated by the benefits of this hygienic,  eco friendly, economic, cost effective, low maintenance water supply scheme.  It is really a boon for rural women

                                                                                                     

Spring Based Mini Piped Water Supply Schemes

In the hilly & far flung habitations where the natural springs are available nearby the habitations, such schemes are implemented for the water supply of the habitations. In this scheme, water of the spring is collected in the chamber and then it is taken in the water storage tank in the habitations through pipeline. Then it is distributed through tap connections / public stand posts. These schemes are implemented since the year 2009-10 as per the Govt. GR No. Apana-1010/ Pra. Kra.50/ Papu-15, Dated 20/02/2010 & Corrigendum Dated 17/10/2012 in the hilly habitations of Sahyadri Ranges in Konkan & Pune region. This scheme has maximum expenditure limit of Rs.10 Lakhs each.  Since the year 2009-10 the total 129 No. of  schemes are completed so far.
