BWSSB — The pipe connecting two manholes broken

Address: Bangalore, Karnataka

Website: MYBWSSB.ORG

PF Layout Vijaynagar. The pipe connecting two manholes is broken and hence blocking our toilets.My house is in 2nd main road PF layout. Near the Ward office.Each time we complain, BWSSB does a temporary work and again after few days the problem resurfaces. Since its the main pipe which is the problem, I expect BWSSB to relay with new ones at no cost..What is the process.There is no respite from toilet bloackages due to this issue.
