From plumbers: Is Bengaluru’s RWH law working?

The demand for installing RWH system has shot up from the last two years as people are now aware of the rainwater harvesting law and the grim water situation.

With the city’s growing water woes, rainwater harvesting has come into focus time and again. It was also made compulsory in Bangalore by law.

The BWSSB (Amendment) Act passed in August 2009, states that every owner or occupier of a building having a sital area of 2,400 sqft and above, or every owner who proposes to construct a building on a sital area of 1,200 sqft and above, should install rainwater harvesting structures.

Following the law and various awareness exercises conducted in the city, it appears that RWH installation pace has picked up much more compared to earlier years. The people who are where the rubber really hits the road are the plumbers.

This is a short four-minute citizen-shot video of one conversation with an experienced Bengaluru plumber, Pradeep Kumar. Listen to his on-the-ground perspective on RWH, the law and Bangalore.

Kumar is from Orissa who has been working in Bangalore for seven years now. He says that the rainwater harvesting projects have increased greatly from the last two years, which proves that the law has kicked in and people are aware of it. “I get around 100 small RWH projects and two to three big RWH projects every month. I also get maintenance calls – typically to clean the filter”, he says.

Pradeep makes one more interesting point. He feels the unreliability of BWSSB or Cauvery water even in areas with water connections is driving up the interest in RWH installations. Kumar feels everyone should practice RWH to cut down on the dependency on piped water.

When asked about where people usually store rainwater, he says, ”They either store it in a tank and use it directly or recharge it using a recharge well of about 20 feet deep”.

Installing a Rainwater harvesting system ranges anywhere between Rs 10,000 to Rs 50,000 depending on the size of the pipe and area he says.

Kumar’s team comprises 30 people and he adds, “There are easily thousand other plumbers who do this like us”, in Bengaluru.

Why concrete lakes are pushing away Bengaluru’s waterbirds

As natural shorelines vanish and extensive restoration destroys habitats, city lakes see a sharp decline in special wetland bird species.

Since Bengaluru’s lakes were formed by damming water flowing down valleys, they are typically wedge-shaped, with a gentle slope and a deep basin towards the embankment. This promotes the growth of diverse vegetation and animals, each adapted to a particular water depth. The result is a natural zonation – reedbeds and shoreline vegetation at the edges, floating and submerged vegetation in the middle, and open water at the deepest end. During the Open City biodiversity datajam held in December 2025, our group examined the ecological trends around Bengaluru’s lakes. In an earlier article, we examined how migrant and resident waterbirds…

Can cool roofs beat Chennai’s heatwaves? A look inside the state’s Green Schools push

Amid heatwaves, the cool roof initiative is being implemented across Chennai schools. But experts warn that it cannot be the single solution for urban heat.

Over the past few years, maths teacher Usha found her classroom sweltering during her usual 12.50–1.50 pm period, on the second floor of Perunthalaivar Kamarajar Government Girls Higher Secondary School. “It was so difficult to take class during the peak hours,” she says. But this year, she mentions that it feels slightly bearable, and attributes this to the shade of the trees, the wind blowing through the building, and the latest addition — solar-reflective paint on the roof. Data from a state government and UNEP Cooling pilot project at the Ambattur school shows that reflective coating brought the classroom’s internal…
