Sintex and plastic tanks are the standard store in Madanpur Khadar, and on the khadar edge they silt up and grow biofilm fast. KaamGenie cleans them with a plastic-safe soft wash and anti-bacterial disinfection. From ₹699.
Madanpur Khadar is a dense mix of resettlement blocks, JJ-colony pockets and newer builder floors on the Yamuna floodplain edge near Kalindi Kunj and Sarita Vihar. Piped DJB supply is irregular, so many buildings lean on borewells and tankers, giving hard, high-TDS water. Rooftop Sintex and plastic overhead tanks with ground-level sumps dominate, and because the plastic walls let light through, algae and a slimy biofilm build up faster than they would in concrete.
The sandy khadar groundwater and frequent tanker top-ups mean silt and mineral scale accumulate quickly, and a warm, light-fed plastic tank turns that into green growth between refills. A plastic-safe clean clears the slime and the silt together, and it works alongside our full water tank cleaning in Madanpur Khadar so both your sump and rooftop tank are covered.
The floodplain groundwater here is sandy and mineral-heavy, so a Sintex tank fed by borewell or tanker water quickly collects a layer of silt at the base. Because the tank walls are translucent, sunlight reaches the water and feeds algae on top of that silt, and the combination becomes a thick slimy film. Irregular refilling means the tank rarely empties fully, so the biofilm just keeps building.
Our crew drains the tank, scoops the sandy sediment out by hand, then soft jet-washes at plastic-safe pressure so the walls are cleaned without being gouged or cracked. We hand-scrub the algae with soft pads, apply a anti-bacterial disinfectant, and reseat the lid and check the overflow so light and dust cannot restart the growth. You receive photos and a sanitisation quality report.
No travel charge anywhere in Madanpur Khadar. The final price is confirmed on the call before we come — it depends only on tank size and access.

“Do you clean Sintex tanks in the JJ Colony pockets of Madanpur Khadar?” Yes, we cover the resettlement blocks and the JJ-colony pockets as well as the newer builder floors. We carry our own soft-wash pump and water, so patchy DJB pressure is not a problem. A single rooftop Sintex tank is normally done in about an hour with photos to follow.
“My tanker-filled plastic tank has sludgy sediment at the bottom. Can you remove it?” Yes, that sandy sludge is typical here because the khadar groundwater and tankers carry a lot of silt. We drain the tank and scoop the sediment out by hand before washing, so it is physically removed, not just stirred around. Then we disinfect so the water is safe to store again.
“Will the wash crack my plastic tank?” No. We use a soft jet at plastic-safe pressure and soft pads instead of wire brushes, so the tank is never gouged or cracked. This is important for the thinner plastic tanks common in the Block A and Block B lanes. The tank is cleaned thoroughly and left intact.
“What is the price for a 1000L Sintex tank here?” It starts from ₹699 for a standard Sintex or plastic overhead tank, and a 1000L unit falls in that range. If you want the ground sump done too, we quote a combined rate for the same visit. The price is confirmed upfront with no hidden charges.
“Can you come same day to the Sarita Vihar side?” Usually yes, depending on slots. We serve the Sarita Vihar and Kalindi Kunj side of Madanpur Khadar daily, so same-day or next-morning visits are normally possible. Share your block and tank size and we will confirm.
