Overview of the existing infrastructure and water supply
● The school gets its water supply from the Panchayat borewell to their sump
● The water is pumped to the OHT from the sump
● From the OHT it is distributed to the hand wash station, toilets, etc.
● There is one drinking water filter but currently not being used
● Anganwadi is in the adjacent campus and receives water from the Panchayat
Issues observed
● Lack of water supply - the quantity of water supplied is not enough for all daily
needs
● Sump size is not adequate
● Anganwadi faces immense water scarcity. Water for cooking is also not available
adequately
● Toilets are newly constructed by Rotary and plumbing has been done, but water
availability is sketchy
2. Existing water supply infrastructure and design
Proposed design solution
Cleaning and reviving the existing rainwater tank in the school
Constructing a ferrocement filter on top of the tank
Connecting the downtake pipe with an appropriate first rain separator (FRS) to the ferrocement filter
Outlet from the filter to be connected to rainwater tank
Provision of taps and plates washing area near this tank
Connecting the rooftop downtake pipes of roof 2 and roof 3
Constructing a ferrocement filter
Connecting the downpipes with appropriate first rain separator (FRS) with the ferrocement filter
Outlet from the filter to be connected to the existing sump in the school
From the sump, the connections already exist to the toilet and hand wash station
3. The work was taken up in the latter half of 2017 with funding support from Ittiam Systems Pvt Ltd.
