Getting a BWSSB Water Connection in Bangalore: Every Charge Explained

Getting piped Cauvery water to a new home in Bangalore means paying the city's water board a bundle of separate fees. What the owner pays turns on three things: how much is built, what the building is used for and whether it belongs to the belt of 110 villages absorbed by the city in 2007. The notes below take each item in turn, then list the checks worth making before money changes hands. For the wider Bangalore context, the city page is a good starting point.

Flat Buyers and House Owners Pay Differently

In a housing society, the builder normally takes a single common water line for all the flats together. That expense is spread into the price, or appears as its own line when keys are handed over. A flat buyer rarely sees a water board demand note in their own name.

An independent house is another story. The owner applies, receives the demand note and clears every head on it. Anyone buying a house, or a site they intend to build on, should count these fees among the costs of settling in.

Applying and Waiting

Applications go through the board's portal or one of its offices. Papers usually asked for are a copy of the sale deed, the khata, the approved plan and the owner's photos. A building of 1,200 square feet or more must also show that rainwater harvesting is installed, and earlier payment receipts help if any exist.

An engineer then visits the site, and the board raises a demand note. When the sum is paid, the pipe is connected and a meter is fitted. The board aims to finish a home connection in two weeks and a commercial or high-rise one in six, although delays do happen.

The Items on a Demand Note

These amounts come from the 2025 schedule for residential applicants, and the board revises them from time to time. Each appears on its own line.

The application fee is Rs. 100 for every kind of connection, and the connection charge is between Rs. 25 and Rs. 100 depending on pipe size. Inspection costs Rs. 250, and apartment complexes pay a higher rate. A half-inch mechanical meter starts at Rs. 965, with larger ones priced higher.

For a home with five sanitary points or fewer, a sewer connection is Rs. 600. The board also collects a minimum three-month deposit, from Rs. 315 for a standard 15 mm household pipe. The two big items are the pro-rata charge and, in the former villages, the beneficiary contribution, covered next.

Understanding the Pro-Rata Charge

For most owners this is the largest line. It is Rs. 400 for each square metre of built-up area, or Rs. 600 where the building is not residential. It is paid once, with no refund.

A house is liable once the plot reaches 1,200 square feet and the building has at least three units or kitchens. Tall residential blocks, commercial premises and schools or colleges pay whatever the plot size.

Because the charge follows total built-up area, a multi-storey block pays more than a one-floor house on the same land. Take a house with 2,400 square feet of built-up space, which is about 223 square metres. The fee works out to roughly Rs. 89,000.

The 110 Villages and the Extra Contribution

Properties in those former villages pay one extra contribution, once only. It helps fund the local pipes that bring water from the Cauvery Stage V scheme, which began supplying in October 2024. For homes, the 2025 schedule scales with size.

A small home of up to 600 square feet pays Rs. 5,000, and one between 600 and 1,200 square feet pays Rs. 10,000. Between 1,200 and 2,400 square feet the amount doubles to Rs. 20,000. Anything larger pays Rs. 30,000.

Kengeri and the seven areas that once had their own city municipal councils were served by an earlier scheme, so a different fee covers them. An owner there should ask the board which of the two is due.

Monthly Bills Once Water Flows

After the connection, billing follows consumption slabs, with a sanitary charge added. The board revised its rates in April 2025, the first change in more than ten years. From 1 April 2026 the tariff rises automatically by 3% a year, so a household budget should allow for small annual increases.

Even so, Cauvery water on a meter is far cheaper than tanker supply. A working connection also helps at resale, since the next buyer will ask where the water comes from.

Six Checks Before Paying

A fee is money well spent only if a tap will really run. These checks protect against paying for a dry connection:

• Check that a board main runs along the street in front of the property
• Establish whether the property is in the 110 villages or the former municipal areas
• Read each line of the demand note and sort the refundable deposit from the one-time fees
• For a flat, ask whether the society's main connection is sanctioned and how each flat's share is billed
• In a resale, make sure the present connection has nothing outstanding before the sale is registered
• Keep all receipts, since a later name transfer or alteration will call for them

These fees look minor against the price of a home, yet they slip out of many budgets. Reach our team through the contact page to learn which of them matter for a project on the shortlist.
