Dear @nirmal707
For a serious issue with sewage water affecting your Kaveri water pipe, I recommend filing a complaint with the Bruhat Bengaluru Mahanagara Palike (BBMP).
For water supply and sewerage issues, call the water helpline number 1916 or email to Bangalore Water Supply and Sewerage Board (BWSSB) at callcenter@bwssb.gov.in.
You can call the BBMP helpline at 1533 / 80-22660000 or send an email to comm@bbmp.gov.in with the details of your complaint and your contact information.
You can also file a complaint online through the BBMP website. Follow the instructions provided to submit your complaint.
Still, have questions? Ask by replying to us.
