1) School Details

The Kariammana Agrahara Government School, Kadubeesanahalli is a single storey building, which stands on an open site, a short drive from Outer Ring Road. The day school employs 2 teachers and offers classes for 113 students from 1st to 5th standard.

2) Overview of Existing Infrastructure

The school does not have a BWSSB connection and the nearby bore well is the only source, it is yielding sufficiently, but is only available when there is power to run the pump. The bore well water is used for drinking as well as washing utensils.

When power is available the containers are filled up using the activity room supply. The school consumes 400 litres a day out of which 120 litres is consumed and the rest is used to wash utensils.

Nearby Community Borewell

Tap and filter in the corner of activity room Water container, used to store drinking water






Plumbing from the borewell to sump, to activity room, and to bathrooms is already available.

The functionality of the existing plumbing to the sump needs to be verified after sump cleaning, other lines are in working condition.

Plumbing from Borewell to activity room, bathroom and sump






A sump tank of 3375 litres capacity (1.5m*1.5m*1.5m) is located in front of the toilets. The sump has not been used due to lack of maintenance and requires cleaning before resuming any operation.

Dirt and debris in sump






The school is equipped with 2 toilets. Presently, the toilets receive intermittent supply from the bore-well depending on the availability of electrical power. The toilets do not have taps and urinals are absent.

Toilets (outside and inside view)






The terrace surface has recently received a fresh layer of concrete with the slope being directed towards the rear. The openings for rainwater down pipes have been provided as well.

Assuming 970mm of rainfall annually and 30mm as average rainfall event, the total rainwater harvested by the 1650 square foot terrace, works out to about 1.48 lakh litres and 4600 litres respectively.

Terrace (30 feet*55 feet)






3) Water Issues
