Washing a car with Cauvery water costs 5,000 rupees. The board fined 22 households in the first two weeks, and the AI meters promised alongside the ban are still a 2,000-connection pilot.

As the water crisis peaked in March 2024 the board cut supply to bulk users by 20% and banned Cauvery drinking water for car washing, gardening, construction and fountains, with a 5,000-rupee fine and 500 rupees a day for repeat offences; apartment complexes above twenty units must already treat and reuse their own sewage. The board reissued the ban in July 2026, extended it to swimming pools and gave buildings until 31 July to fit tap aerators — the equivalent 2024 deadline had been pushed back. The promised AI water meters remain a 2,000-connection pilot.
📊 Impact
The water board counted 22 households fined 5,000 rupees each, 1.1 lakh rupees in all, in the first two weeks of enforcement of the March 2024 ban. The substitute it points people to is thinly plumbed: only one in five homes have rainwater harvesting, the board sold 163.28 million litres of treated water in February 2025 and collected 59,28,839 rupees for it, and the smallest quantity it offers is 6,000 litres. The AI meters announced in December 2024 remain a 2,000-connection pilot for bulk consumers — commercial users are about 10% of connections and take around 41% of the Cauvery supply — against roughly 1.09 million consumers already metered mechanically at the tap.
🎓 Lesson
The city has a price signal and has forbidden itself from using it. A 2020 regulation makes internal water meters compulsory in every flat of an apartment block above a size threshold, but only from a date the state government never notified, with no penalty attached — and the regulation says in terms that those readings may not be used to calculate the board's bills. The meter measures and the bill is still split evenly. What is left to shape demand is prohibition: 5,000 rupees for washing a car, 500 a day for repeating it, and up to half the supply cut off. The reuse rules ran the same way. Since 2016 apartments above twenty units on the sewer network have had to build their own treatment plant or pay a levy of a quarter and then half of the monthly bill, and by December that year around 1,900 of the 3,348 such blocks had been billed the levy. Underneath all of it sits an arithmetic no fine reaches: the city draws about 1,372 million litres a day of groundwater on top of 1,460 from the Cauvery, against natural recharge estimated as low as 148.
