Now, BWSSB to desilt only 15,000 manholes

According to BWSSB officials, the Board has already completed work in 8,000 manholes mainly in the low lying areas and will be finishing work in 7,000 manholes in the coming days.  

An official said that there was no need to clean all 50,000 manholes, as problem occurs mainly in manholes that are located in lower gradient areas, where the silt from the stormwater drains easily enters the manholes. Complaints related to overflowing of manholes mainly come from these areas.

Around 300 manholes are desilted in a day on an average. BWSSB does not have any record of the quantity of silt being removed. Besides paying for transporting silt, no other payment is made by the Board.

Work on cleaning up sewer lines and desilting was launched after the City experienced large-scale waterlogging during rain in the third week of April. Following the chief minister’s intervention, an action plan was drawn up by Bruhat Bangalore Mahanagara Palike (BBMP), Bangalore Development Authority (BDA) and BWSSB. As part of the action plan, BWSSB took up desilting of the manholes.

The Board has 76 jetting machines to declog the water and sanitary pipelines. An additional 50 machines will be bought by the Board to cater to the problems in the coming monsoon.
