    A software engineer is offering guidance to anyone seeking to set up a low-cost rainwater harvesting system

    Sriram Vasudevan, a software engineer, uses his free time for work involving hardware. Not the hardware you associate with computers. He’s working with PVC pipes, L-joints and valves and other material necessary to build rainwater harvesting (RWH) systems. Having set up a self-designed, cost-effective RWH structure at his house in Ramapuram, he is helping others install such structures at theirs.

    He had been researching intensely on how to install cost-effective RWH structures before devising such a model himself. He says this work is motivated by a desire to solve water-related problems in the city. Sometime ago, he posted an announcement on Facebook, expressing his desire to guide anyone who wants to install such an RWH structure. “My friend Balaji set up an RWH structure at his house recently and I was greatly inspired by it. I believe a good RWH structure in each house will help solve many water-related problems in the city,” he says. Here’s how this model works.

    “The rainwater that gets collected in someone’s terrace should be directed to their borewell, well or sump,” he explains. In regular RWH systems, the collected rainwater is directed to a rainwater harvesting pit dug near the house. This pit has a layer of coarse pebbles to help filter impurities and channel the water underground directly. In a variation of this model, Sriram suggests that a valve be placed in the RWH pipes.

    This valve is capable of clearing out the impurities, thereby helping bypass the need for a rainwater harvesting pit.

    Sriram says channeling the collected rainwater directly to the borewell will help improve water quality.

    “There will be a evident change in water quality and taste, post-monsoon,” he says.

    He points out that in case of any overflow in the collection system, an extra tank can always be set up to store excess water.

    Sriram has already helped two residents set up RWH structures at their houses.
