Water sits, sediment settles
Intermittent supply means water stands for hours — chlorine fades, silt drops and biofilm forms on the walls.
Treated at the source, but only as clean as your tank.
Intermittent supply means water stands for hours — chlorine fades, silt drops and biofilm forms on the walls.
Below ground, it collects the heaviest silt and monsoon seepage — cleaning only the top tank just recycles the muck.
Blending DJB with borewell adds hard-water scale and mineral sludge, so mixed-supply tanks need cleaning sooner.
Homes and DDA flats: every 3–6 months. Big societies: quarterly. Can’t recall the last clean? You’re overdue.
Date, capacity and before-after photos in a folder answer any resident or inspector who asks when it was last done.
Food-grade process timed around your DJB hours — drained, cleaned and refilled with a service record.
