Why Regular Water Tank Cleaning is Essential in Bengaluru
Bengaluru tanks build up three kinds of contamination. Sediment, rust, sand and minerals settle into a sludge layer at the bottom. Algae grow on walls exposed to light, adding a musty taste and feeding bacteria. Biofilm, a thin bacterial layer on the walls, recontaminates even fresh water. Borewell water speeds all of this up. A tank uncleaned for over 12 months is almost certainly contaminated, even if the water looks clear.
Most Bengaluru homes store water in two stages: it fills the underground sump, gets pumped to the overhead tank, then flows to your taps. Clean only the overhead tank and the dirty sump keeps pumping contamination back up, so the cycle never breaks. Cleaning both together is the only way to get clean water through the whole system. KBS cleans tank and sump on the same visit.
Borewell water carries far more minerals, sediment and bacteria than treated Cauvery water, and its quality changes with depth and season. In the monsoon, surface water can seep in through poorly sealed caps, carrying bacteria and pesticides. Borewell homes should clean their tanks every 4 to 6 months, not yearly. A periodic water test alongside the clean is the only sure way to know it is safe to drink.
After scrubbing, the tank is disinfected to kill bacteria and leftover biofilm. Potassium permanganate is the government-recommended disinfectant for water tanks: food-safe, broad-spectrum and residue-free after rinsing. Bleach, the cheaper option, can corrode plastic walls and leave chlorine in the first few batches of water. KBS uses potassium permanganate at the right strength followed by a full rinse, the process the Bureau of Indian Standards recommends.
Some signs mean your tank needs cleaning now: brown or yellow water (rust or sediment), a musty smell (algae or bacteria), slippery walls (biofilm), stomach upsets from home water, heavy scale after boiling, or floating particles. If you see any of these, don't wait for the yearly clean. Call KBS, most of Bengaluru is covered within 24 hours.
