KPMG, as a part of its Corporate Social Responsibility program identified RVCE for implementation of a rainwater harvesting system. The first phase of this project was executed way back in 2010 with design inputs from Biome The rooftops of three blocks were tapped and directed to a 150 KL sump. This system helped the college in harvesting close to 3 million litres of rooftop runoff annually. Additionally, the overflow from the sump was fed to a recharge well which helped in replenishing the ground water table.
Buoyed by the success of the first phase, the second phase was planned with the intent to increase the quantum of rainwater harvested. This involved tapping rooftops of two hostel blocks (Chamundi and New
MV Block) adding up to an area of 2439 sq m. The runoff is directed to
two brick masonry filters, whose output is led to a new 50 KL sump. A 3
HP centrifual pump does duty to pump the water from this sump to one of
the colleges’ existing sump.
The complete system was inaugarated by officials from KPMG on the 23rd October, 2013.
This system has the potential to harvest around 1.6 million litres a year.
The open well in the campus gets the surface runoff of the campus
that flows in the storm water drains. Consequently, the well is filled
with all kinds of debris and is a picture of neglect in its current
state. It is high time that the cleaning up and maintenance of the well
is taken up as one of the main action items for the next phase of the
rain water harvesting initiative in the college.
