In Sunder Nagari’s Nand Nagri belt, very hard borewell scales the small plastic tanks fast and drops a fine grit in the base. KaamGenie cleans them gently, hygienic and photographed. From ₹699.
Sunder Nagari is a resettlement colony in the Nand Nagri belt of North-East Delhi, dense EWS rows and small workshop units on the Mandoli edge. The interior supply leans on borewell that runs very hard, so small Sintex and plastic tanks scale up quickly and the base fills with a fine grit. On the translucent plastic the sun then grows algae, because light passes through the wall and warms the water on top of the mineral scale. Buildings here are compact, with owner-built cisterns and modest overhead tanks, and cleaning is rarely on any schedule. Left between cleanings, the hard-water scale hardens onto the plastic floor and the grit clouds the first draw, so the water turns before most families think to look inside.
KaamGenie cleans Sintex and plastic tanks across Sunder Nagari and the Nand Nagri edge. We check the tank and lid, drain it, scoop out the gritty settled layer, wet-vacuum the base, jet-wash at a plastic-safe pressure to lift the scale without harming the wall, then finish with an anti-bacterial disinfectant wash and before and after photos. To include an owner-built cistern in the visit, see our full water tank cleaning in Sunder Nagari. This page focuses specifically on Sintex and plastic tanks.
Sunder Nagari’s borewell runs very hard, and that is the main reason the small plastic tanks here scale so fast. Calcium settles as a white crust on the plastic floor and around the outlet, and a fine grit collects in the base within a few months. On a translucent Sintex tank the sun compounds it, letting light through the wall to warm the water and grow an algae film over the scale. A concrete tank blocks that light, so the same hard water leaves less of a green film in an RCC store than in the plastic tanks common here.
The tanks in Sunder Nagari are small and often owner-built alongside modest cisterns, and cleaning is rarely scheduled, so the hard-water scale is left to harden onto the walls. A first deep-clean here usually clears a crust that has set over years. High household density on each plot keeps the tank filling and draining, stirring the grit back into the water, and the loose lids on the compact roofs let workshop dust in from the Mandoli edge. Together the scale, grit and film cloud the water well before anyone opens the tank.
No travel charge anywhere in Sunder Nagari. The final price is confirmed on the call before we come — it depends only on tank size and access.

“Do you clean the small plastic tanks in Sunder Nagari?” Yes. The modest Sintex and plastic overhead tanks common across the Nand Nagri rows and the Mandoli edge are exactly what we clean here. Whether it is a single owner-built tank or a couple of tanks on one plot, our crew reaches you with plastic-safe cleaning throughout.
“The borewell here is very hard. Can you remove the scale?” Yes. We drain the tank, scoop and wet-vacuum the gritty base, then jet-wash the walls at a pressure set for plastic so it lifts the hard-water scale without cracking the Sintex. A first deep-clean clears the crust that has built up, and regular cleaning after that keeps it from setting hard again.
“How much to clean a small Sintex tank here?” A tank up to 500 litres starts at ₹699, which covers most of the small tanks in Sunder Nagari, and a standard 1000L is ₹899. If several tanks on a plot or block are done together, we apply a bulk rate on four or more, bringing the per-tank cost down.
“Why does my plastic tank scale so fast?” Because Sunder Nagari’s borewell is very hard, so calcium settles as a crust on the plastic floor and outlet within months, and the sun through the translucent wall grows algae over it. A concrete tank blocks the light and shows less green, but the scale still needs regular cleaning wherever the water is this hard.
“Will jet-washing crack an owner-built plastic tank?” No. We set the jet pressure specifically for plastic, so it lifts scale and grit without gouging or cracking the wall, and we hand-scrub stubborn crust with soft pads rather than wire brushes. Wire brushes scratch the plastic and let scale and algae grip faster, so we avoid them on every tank in Sunder Nagari.
