Poor families in Bengaluru are spending about ₹3,000 a month on drinking water bought from private tankers, according to preliminary findings of a household survey by the Water Satyagraha campaign, The Hindu reported.
"Poor families spend around ₹3,000 a month on drinking water, which is higher than the ₹2,000 monthly assistance provided to women under the Gruha Lakshmi scheme of the government of Karnataka," said Syed Ahmed Hussain, the campaign's convenor and a vice-president of the Karnataka Pradesh Congress Committee (KPCC). Some middle-class families spend as much as ₹54,000 a year on drinking water alone, the survey found.
The findings come with a crisis expected next summer after a 43% deficit in the south-west monsoon. These are the campaign's own preliminary figures, not an official audit; volunteers aim to survey three lakh households by March 2027 and submit a report to the state government.
What the survey found
- Bengaluru gets about 1,470 million litres a day (MLD) of Cauvery water against an estimated daily demand of more than 2,100 MLD; the campaign predicts a shortfall of over 600 MLD.
- The city produces about 2,120 MLD of sewage a day and treats 1,348 MLD, leaving 772 MLD untreated.
- Every taluk in Bengaluru Urban district is classed as over-exploited for groundwater, and the city draws groundwater at nearly twice the rate it is recharged, Mr Hussain said.
- The city loses about 400 million litres of piped water a day, and nearly 27% of piped water goes to leaks, theft and unbilled use.
- The Bangalore Water Supply and Sewerage Board (BWSSB) has no power to regulate what private tankers charge.
Mr Hussain also alleged that the BWSSB tests 80 to 150 water samples a day but does not publish ward-wise data on contamination and pipeline leaks. No response from the board is reported. Across Karnataka, 226 of 240 taluks have been declared drought-hit this year, he said.
Background
Tanker prices have been a sore point before. In the 2024 crisis, a standard 12,000-litre tanker cost between ₹1,200 and ₹3,000 depending on urgency and location, with prices rising in the dry season or when BWSSB supply was disrupted, Down To Earth reported at the time.
