Underground Sump Cleaning in Preet Vihar

Underground sumps in Preet Vihar

One of East Delhi's more affluent addresses, Preet Vihar is a grid of independent kothis and premium builder floors flanking Vikas Marg, with the commercial spine gathered around the metro. The larger houses hold sizeable underground sumps that store DJB supply before pumps push it to individual rooftop overhead tanks. Owners here expect a proper, recorded clean rather than a quick rinse, and the hard supply leaves scale on the sump floor that only a physical scrub removes. On the bigger plots the sump can hold several thousand litres, enough that neglect shows quickly in taste.

We ventilate and air-test the sump, pump it down to the sludge, remove silt by hand and wet-vacuum, then jet-wash and sanitise before refilling, with before and after photos sent on WhatsApp. Households that also want the rooftop tank serviced can add our water tank cleaning in Preet Vihar. This page is about the buried reservoir that takes the first fill.

Why the large sumps in Preet Vihar need a documented clean

Because every drop the house uses passes through the sump first, sand and grit from the DJB line settle there before cleaner water is lifted to the roof. On the bigger kothi plots the reservoir is large and low-turnover, so water can sit for spells and let fine sediment and biofilm settle undisturbed on the floor. Hard supply adds a chalky scale that thickens on the walls over the years.

These sumps sit sealed under the driveway or car porch, off the household maintenance list until the water tastes flat. Older ones may not have been opened since the house was built, and can carry hairline cracks that admit seepage. For owner-occupiers who care about the water reaching their kitchen, a scheduled drain, scrub, disinfect and written record is worth far more than a surface rinse.

How we do it — our 6-step process

• 1. Drainage We open and ventilate the sump, then pump out the standing water down to the sediment layer.
• 2. Sludge Removal Years of settled silt, sand and sludge are scooped and cleared out manually.
• 3. Vacuum Cleaning Industrial wet-vacuums clean the loosened dirt from the floor and corners.
• 4. High-Pressure Jet A high-pressure jet wash lifts caked mud, scale and biofilm off the walls and floor.
• 5. Anti-Bacterial Wash A disinfectant wash sanitises the sump before it refills.
• 6. Quality Report Before and after photos are sent to you on WhatsApp.

Common questions from Preet Vihar customers

“We want a proper record of the sump clean, not just a verbal all-clear. Do you provide that?” Yes. Every Preet Vihar job comes with dated before and after photos and a short written note on the WhatsApp report, including any wall cracks or seepage we spot. Owner-occupiers here usually want exactly that documentation.

“How much for a large kothi sump on Vikas Marg?” Pricing runs by capacity from ₹1,499 for up to 1,000 litres. A 2,001 to 5,000 litre kothi reservoir typically falls in the ₹2,500 to 3,500 band, confirmed once we see the tank. Larger plots are quoted on the day.

“Our sump has not been opened since the house was built. Is that a problem?” It is common on the older plots and no obstacle. We open it carefully, ventilate and air-test before entry, and expect a heavier scale and sediment load on a first clean. We also check the ageing RCC for cracks while inside.

“Can you clean the sump without disrupting the whole day's supply?” Yes. We drain and clean while the rooftop tank keeps the taps running, and refill the sump once it is sanitised, so the household barely notices. A full-size kothi sump is usually done within a few hours.

“Do you descale the sump walls or only remove the sludge?” Both. We wet-vacuum the settled silt from the floor and separately work the chalky scale off the walls that Preet Vihar's hard supply leaves, then disinfect the cleaned surfaces before refill.
