Where Does the Water Come From? Borewell Permits and Charges for Bangalore Flats
A flat that looks perfect on the day of the visit can run short of water in March. Borewells feed a large share of apartment buildings in Bangalore, and since 2025 Karnataka has regulated them more strictly. What follows explains the new permit rule, what compliance costs a society and which questions a buyer can put to the builder or the association.
Water Questions Worth Asking First
Water supply deserves the same attention as price and title. At a project in Bangalore, begin with these:
- Which share of daily demand is met by Cauvery pipes, which by borewells and which by tankers?
- How many borewells are on the site, and what does each yield in the dry months?
- Does a groundwater NOC exist for the project, and who holds it?
- Are meters fitted to the borewells, and who files the returns?
- Does recycled water from the sewage plant go to flushing and landscaping?
- What capacity do the rainwater storage and recharge works have?
- How much of each flat's monthly maintenance bill goes to water?
The association's accounts will answer most of this in a completed building. For one still being built, ask the builder for written replies and have the sale agreement list the water sources.
The Permit Rule Explained
Societies running apartments or group housing may take 20,000 litres (20 cubic metres) of groundwater in a day for domestic and drinking purposes without a permit. A bigger draw needs a No Objection Certificate, or NOC, issued by the state's Ground Water Authority. A householder using a borewell only for the family's own needs is exempt, and so are farmers.
Private tankers that sell groundwater in bulk now fall under the NOC requirement as well. The government may also notify charges for groundwater used in commerce, industry, mining, infrastructure projects and bulk supply.
How the Law Got Here
A state statute of 2011 first governed groundwater. It created the Authority and gave it control over permits, meters, inspections and closures, yet the permit rule applied only in those localities the Authority had notified.
An amendment placed before the Assembly in 2025 and notified by September 2025 spread the rule across the whole state. It adopts central groundwater guidelines and fulfils a budget announcement for 2025-26. The list of exempt users was redrawn at the same time, which is the source of the apartment figure.
Turning the Limit Into Homes
Planning norms assume 135 litres per person each day, so a household of four uses 540 litres. Divide the permitted 20,000 litres by that number and about 37 homes result, if borewells provide everything.
The count doubles to about 74 homes when borewells give only half the supply and Cauvery connections give the rest. Several hundred flats running mostly on borewells would pass the limit easily and would require the certificate.
The certificate and its conditions
Each NOC sets the volume a project may extract and attaches conditions. These conditions, drawn from central norms that the state now adopts, relate to meters, regular reports of quantities taken and rainwater recharge within the plot. After handover the association should keep the certificate in its name and watch for the renewal date.
Fines and Meters
An older provision lets the Authority order a meter on any borewell. A user who has not installed one after 30 days risks having it fitted by the Authority at the user's expense. Inspectors may also look at wells and records, and may close a borewell that is illegal.
The amendment adds firmer penalties:
- A penalty of Rs. 50,000 at most where information or returns are refused or falsified
- A running penalty, never more than Rs. 1,000 a day, while the failure lasts
- Further penalties, at rates the government notifies, for taking water with no valid NOC or outside its terms
An association is a shared body, so any fine or closure order is passed on to every flat owner. They feel it through maintenance dues or through the price of tankers.
What Compliance Adds to Monthly Dues
For a society, groundwater was once cheap, with power for pumps and repairs as the main costs. A project over the exempt limit can now expect extra items:
- Meters on all borewells plus equipment that reports readings
- Charges on extracted volume, wherever notified rates reach the project
- Application and renewal costs for the NOC, often with consultant fees
- Upkeep of recharge wells and rain collection systems
Compared with tanker water the sums are modest, but they recur monthly. Recycling treated water for flushing and landscaping lowers extraction and trims these costs.
Cauvery connection alongside borewells
A sanctioned BWSSB connection lowers dependence on borewells, although big projects frequently run both. Check the connection papers and supply hours next to the groundwater permit.
Steps for Current Residents
Associations can begin with a water audit. Meter readings over a month show whether the borewells go past the exempt limit. If so, apply for the NOC, install meters and keep a file of returns.
Saving water usually costs less than paying for extra extraction. Fixing leaks, adding aerators, reusing treated water and putting rain back underground all shrink the draw. Anyone thinking of moving to a locality with a steadier supply may write to our team via the contact page.
