Naya Bans traders work below cramped living floors, and the small plastic terrace tank up top greens quickly because light passes through its walls. KaamGenie cleans it gently, hygienic and photographed. From ₹699.
Naya Bans is a wholesale lane in the Sadar Bazar cluster, crowded with spice, dry-fruit and general-goods traders who live in quarters above their old shopfronts. The rooftop store here is a small Sintex or plastic tank, and it sits exposed under the thick market dust despite the piped DJB supply. Because Sintex plastic is translucent, terrace sun passes through the wall and warms the water, giving algae and biofilm the heat to establish. Fine spice-market grit drifts in past worn lids and settles on the tank floor. A concrete store would block that light, but a plastic one lets it in, so the inside greens up before the traders upstairs notice. Reached only up steep, goods-choked staircases, these tanks are routinely postponed for months.
On these cramped terraces we keep it gentle: check the plastic body and lid, drain the tank, hand-scoop the slimy sediment, wet-vacuum the base and jet-wash at a plastic-safe pressure. We work the algae film off with soft pads instead of wire brushes and finish with an anti-bacterial disinfectant wash, then send before and after photos. If the building's ground sump or an RCC tank also needs cleaning, see our full water tank cleaning in Naya Bans. This page is specifically about Sintex and plastic tanks.
The plastic wall lets light in. A Sintex tank on a Naya Bans terrace is translucent, so market-lane sun passes through and warms the water, and that warmth is the condition algae and biofilm need to bloom. A concrete tank keeps the light and heat out, so it stays clearer, but the exposed plastic tank warms and greens. On the same DJB supply, that difference is why the plastic tanks here need cleaning more often than owners assume.
Then the spice-market dust piles on. Naya Bans air is thick with grit that drifts into the tank through loose lids and settles as a rough film on the plastic floor. Algae grips that deposit and holds far harder than it would on clean plastic, so the coating thickens fast. Because the tanks sit above busy godowns and can only be reached up narrow, stock-packed stairs, cleaning is deferred for long stretches, and the sediment and film build well past the point most traders realise.

“Can you clean the terrace tank on a Naya Bans trading house?” Yes, that is a routine walled-city job for us. A small Sintex on the roof of a spice or dry-fruit shop with living floors above is cleaned in one visit, checked, drained, scooped and disinfected.
“The market throws up a lot of dust, how often should I clean?” Because Naya Bans air is so dusty, we suggest cleaning a plastic tank here every three to four months. Regular clearing stops the gritty base from building and keeps the algae film from getting a firm hold.
“What is the cost for the small tank on my shop roof?” A Sintex up to 500 litres starts at ₹699 and a standard 1000L is ₹899. Bigger 1000 to 2000L tanks are ₹1,299 to ₹1,499, and multiple plastic tanks on one building get a bulk per-tank rate.
“Will your cleaning damage an older plastic tank?” No. We set the jet pressure for plastic so it lifts grit and biofilm without cracking the wall, and we scrub with soft pads, never wire brushes, so the plastic is not scratched. Older tanks are cleaned the same careful way.
“Can you work before the godown opens for trade?” Yes. Many traders book an early slot so the roof is free before business starts, and we fit the drain and clean to your water-supply timing so the tank is full again by mid-morning.
