1)School Details
The Kariammana Agrahara Government School, Kadubeesanahalli is a single storey

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.

 No water storage for long term use as the sump has not been maintained
 Insufficient water pressure, renders the existing water filter useless
 No urinals in the bathroom
