BWSSB New Water Connection Charges in Bangalore: What a House or Flat Owner Pays
A new water connection from the Bangalore Water Supply and Sewerage Board (BWSSB) is billed as a set of separate charges, not one fee. The total depends on the built-up area, the type of building and whether the property is in one of the villages added to Bangalore in 2007. This guide lists each charge, how it applies to a flat buyer and to a house or site owner, and the checks to make before paying.
Who Pays for the Connection?
The answer depends on the kind of property. In an apartment complex, the developer applies for one bulk connection for the whole project and pays the charges for it. That cost usually reaches buyers through the sale price or a separate line in the cost sheet at possession.
The owner of an independent house or a building on a private site applies directly and pays every head on the demand note. For a buyer of a new house or a site that will be built on, the full set of charges below is part of the cost of moving in.
The Main Charge Heads
BWSSB raises a demand note after an engineer inspects the property, and that note lists each charge separately. The heads and amounts below follow the board's schedule as published in 2025, and they are revised from time to time. A residential applicant will typically see these charges:
| Charge | Residential amount | Notes |
|---|---|---|
| Application fee | Rs. 100 | Same for all connection types |
| Pro-rata charge | Rs. 400 per sq m of built-up area | Rs. 600 per sq m for non-residential buildings |
| Beneficiary contribution | Rs. 5,000 to Rs. 30,000 | Only in the 110 villages, by built-up area |
| Connection charge | Rs. 25 to Rs. 100 | Depends on pipe size |
| Inspection charge | Rs. 250 | Higher for apartment complexes |
| Water meter | From Rs. 965 | Half-inch mechanical meter; larger meters cost more |
| Sewer connection | Rs. 600 | Domestic, up to five sanitary points |
| Three-month minimum deposit | From Rs. 315 | For a 15 mm domestic line |
How the Pro-Rata Charge Works
The pro-rata charge is usually the largest single item, and it is paid once and not refunded. For houses, it applies when the plot is 1,200 sq ft or more and the building has three or more units or kitchens. High-rise buildings, commercial buildings and educational institutions pay it whatever the plot size.
The charge is worked out on the total built-up area, so a taller building pays more than a single-floor house on the same plot. As an illustration, a house with 3,600 sq ft of built-up area across three floors works out to about 334 sq m. At Rs. 400 per sq m, the pro-rata charge comes to about Rs. 1.34 Lakhs.
Extra Charges in the 110 Villages
Properties in the 110 villages that joined the city in 2007 pay a one-time beneficiary contribution charge. It helps fund the local pipe network that carries water from Cauvery Stage V, which was commissioned in October 2024. For a domestic property, the 2025 schedule set the amounts by built-up area:
- Up to 600 sq ft: Rs. 5,000.
- 600 to 1,200 sq ft: Rs. 10,000.
- 1,200 to 2,400 sq ft: Rs. 20,000.
- Above 2,400 sq ft: Rs. 30,000.
A separate fee applies in the seven former city municipal council areas and Kengeri, which were covered by an earlier water project. A property in any of these areas should check which of the two applies before paying.
How to Apply
Applications are made online on the BWSSB portal or at a BWSSB office. The usual documents are the sale deed, the khata certificate, the approved building plan and photographs of the owner. Properties of 1,200 sq ft and above also need proof that rainwater harvesting is in place, along with receipts for any earlier charges paid.
After the application, an engineer inspects the site and BWSSB issues the demand note. Once the amount is paid, the connection and meter are fitted. The board's target is 14 days for a residential connection and 42 days for commercial or high-rise buildings, though some cases take longer.
What Water Costs After the Connection
Once a connection is live, the monthly bill follows a slab tariff based on the water used, plus a sanitary charge. BWSSB revised its tariffs in April 2025 for the first time in over a decade. From 1 April 2026, the board raises tariffs automatically by 3% every year, so the monthly bill should be budgeted to rise a little each year.
Even with these increases, metered Cauvery water costs far less than tanker water. A connection that works is also worth more at resale, because the next buyer will check the water source as well.
Checks Before Paying the Charges
The charges are worth paying only when water can actually reach the property. These checks help avoid paying for a connection that stays dry:
- Confirm that a BWSSB line runs on the street itself, not only somewhere in the ward or village.
- Find out whether the property falls in the 110 villages or the former municipal council areas.
- Read the demand note line by line and separate the refundable deposit from one-time charges.
- For an apartment, ask whether the bulk connection is sanctioned and how each flat's share is billed.
- For a resale home, check that the existing connection has no unpaid dues before registration.
- Keep every receipt, as they are needed later for a name transfer or a change in the building.
Water charges are small next to the price of a home, but they are easy to miss in a budget. Our team can help a buyer work out which charges apply to a shortlisted project, and the contact page lists how to reach us.
