How Often Should You Clean Your Water Tank?

Ber Sarai’s student-rental buildings run their Sintex tanks hard, and constant turnover plus light through the plastic walls means algae builds up fast. KaamGenie drains, scrubs and disinfects your Sintex / plastic tank properly. From ₹699.
Ber Sarai is a compact urban village beside JNU and IIT Delhi, dominated by tall student-rental buildings, PG accommodation and older houses. Supply is a mix of DJB pipeline water and supplementary borewells, and heavy tenant occupancy means constant storage demand. Rooftop overhead tanks plus underground sumps and booster pumps are standard, and where those tanks are Sintex or plastic the light passing through the walls, combined with borewell sediment and high daily turnover, lets algae and biofilm form quickly.
We service the whole village — the main market lanes, the JNU and IIT gate sides, and the Katwaria Sarai and Kishangarh borders — cleaning plastic tanks the safe way plus sumps and boosters where needed. For sump and concrete-tank work, see our full water tank cleaning in Ber Sarai service. PG and building owners can book a whole-block clean in one visit.
The translucent walls of a Sintex tank let light in, and light plus warmth is what algae needs to bloom into a slimy green film. In Ber Sarai the borewell water adds sediment and nutrients, so the biofilm returns quickly even after a rinse. Wire-brushing it off would only scratch the plastic and give the next bloom more grip.
Heavy PG and student occupancy means tanks are drawn down and refilled constantly, churning up sediment and keeping the water warm and moving through the day. Booster pumps pull that disturbed water and sediment straight into the supply line. We scrub the walls with soft pads, disinfect with a food-grade solution, and reseat the lid so light and dust are shut out.
No travel charge anywhere in Ber Sarai. The final price is confirmed on the call before we come — it depends only on tank size and access.

We reach every pocket of Ber Sarai — and there’s no travel charge to any of them:
“Do you clean Sintex tanks for PG buildings near the JNU side of Ber Sarai?” Yes, we regularly clean tanks for PGs and rental buildings on the JNU and IIT gate sides and around the main market. With heavy tenant turnover we can schedule the clean for a low-use time so tenants are not left without water. Whole-block jobs with several rooftop tanks and a sump are handled in one visit. Share the building details and number of tanks when booking.
“Tenants say the Sintex water looks green — what causes it?” That green tint is algae growing on the inside walls, which happens fast in Ber Sarai because the plastic tanks let light through and the water turns over constantly. It is not safe to drink once it reaches that stage and can smell off. We drain the tank, hand-scrub every wall with soft pads, and disinfect with a food-grade solution so the green is gone. Reseating the lid keeps sunlight from feeding a new bloom.
“Will jet washing damage the plastic tanks on our rental building?” No. We use a soft jet at plastic-safe pressure that lifts sediment without gouging the walls, then hand-scrub the algae film with soft pads rather than wire brushes. That keeps the tank walls and joints intact, which matters on buildings where tanks are refilled and stressed daily. Smooth walls also mean algae has less to cling to afterwards.
“What does a 1000L Sintex tank clean cost in Ber Sarai?” A single 1000L Sintex or plastic overhead tank starts from ₹699, including drain, scoop, soft jet wash, hand-scrub, disinfection, photos and a certificate. For a PG or building with multiple rooftop tanks plus a sump, we give a combined price on a quick call. There are no hidden add-ons once we start.
“Can you come same-day, and why are there black flakes in the supply?” Same-day is often possible in Ber Sarai if you call early, which suits PGs that cannot afford downtime. The black flakes are usually decayed algae and borewell sediment stirred up by constant tenant use and pulled through by the booster pump. A full drain, scoop and disinfection removes them, and reseating the lid stops fresh dust and light restarting the cycle.
