Bangalore Water Supply & Sewerage Board [Bwssb] — Sewage flowing inside parking

Dear Sir,
We at Aroma Apartment yesterday faced issue at opposite to our building which entered our car parking causing health hazard.
1. Please do the needful and clean the gutter cleaning with JCB
2. Please increase the height of gutter and put concrete to increase the size
3. Need to replace cement pipeline to this guttter
4. It turned out the next street water entering through small gutter

Not sure why are we paying property tax and income tax... If we have to do everything ourself. Almost 100 - 150 families in this street

Aroma apartment, Old Mangammanpalya Road, next to eucharist church, ward no. 190, Yellukkutte village, Bommanahalli -560068
