Water conservation through rainwater harvesting RV College of
Engineering, Bangalore, has over the past year collected and
used close to 17 lakh litres of rainwater. This is the result of
a project undertaken alongwith Bangalore based Biome
Environmental, which is engaged in ecological architecture and
responsible water practices, to store the rooftop rainwater and
use it in day to day activities including drinking. The only
source of water for RV College of Engineering (RVCE) was
borewells. This was not found sustainable. In general,
groundwater has many quality issues – it is a little too hard
which means there are excess minerals especially in the form of
carbonates. In order to make the groundwater suitable for
drinking, the water from the borewells had to be passed through
a six stage purification process which included “softening” as
well as reverse osmosis. Since both the issues of quantity and
quality had to be addressed, the college decided to go for
rainwater harvesting taking help from Biome Enviro
