The Water Connection ID (also known as Consumer Number, K Number, or RR Number) is a unique reference number assigned to a property by the municipal corporation or water supply board (like DJB, BWSSB, CMWSSB). It is used to identify the water connection for billing, meter reading, and tax collection purposes.
Just like electricity, water is a metered (or sometimes flat-rate) utility in urban India. To pay your water bill online via Paytm, PhonePe, or the official Jal Board website, this Connection ID is mandatory.
What Does Water Connection ID Mean
It represents your legal right to access the municipal water supply. In Delhi (DJB), it is often a 10-digit K NO. In Bangalore (BWSSB), it is an RR Number (Revenue Register Number).
Why Water Connection ID is Important
- Bill Payment: Essential for clearing dues.
- Proof of Address: A water bill with this ID is a valid address proof for Aadhaar or Passport updates.
- Grievance: Required to complain about water contamination or shortage.
Where is Water Connection ID Used
It is printed on the physical water bill delivered to your home. It is also required when applying for a sewerage connection.
How to Find or Check Water Connection ID
- Look at the Bill: Top right corner usually.
- Door Sticker: In some cities, meter readers stick a QR code or ID on the gate.
- Online Search: Use the “Search by Name” feature on your municipal website.
Example of Water Connection ID
K No: 9876543210 (Delhi)
RR No: E-123456 (Bangalore)
Common Problems or Errors
- Old vs New ID: Municipalities often migrate data. Ensure you are using the new “Digital” Consumer Number if the system has been updated.
Important Things to Remember
- Water bills often come quarterly or bimonthly.
- Check Electricity CA Number as both bills often require similar payment steps.
- Check Bill Cycle.
- Check Consumer ID.
For issues, visit your municipal board office.
