Cauvery or borewell: the water question nobody asks

When you view a flat you ask about the rent, the deposit, maybe the parking. Almost nobody asks the question that decides a real slice of the monthly cost and a lot of the daily aggravation: where does the water actually come from?

There are broadly two answers. Cauvery, the piped city supply, metered and fairly predictable. Or a borewell, topped up by tanker trucks when it cannot keep up. Plenty of buildings run on a mix. A tanker-dependent summer costs real money and real planning, and the people paying for it are the residents, through maintenance.

Ask the block, not the area

The trap is treating water as a fact about a neighbourhood. It is not. The Cauvery line reaches some streets of an area and skips others. Two buildings a hundred metres apart can have completely different water situations. So the question has to be asked of the building, not the pin code.

• Ask directly: Cauvery, borewell or both, and on how many days a week?
• Ask what a summer month costs. If the owner shrugs, ask the security guard, who watches the tankers arrive.
• Check the sump and the overhead tank. Good storage smooths over a lot of supply trouble.

Borewell water is not a dealbreaker. Whole lovely neighbourhoods run on it. The point is to know the cost and the reliability before you sign, instead of discovering them in your first dry season. The feed asks this in every area, and the answers come from people actually paying the tanker bills.

Water is not a fact about the area. It is a fact about the block.
