Sainik Farms — sprawling farmhouses and kothis on large plots south of Khanpur, almost entirely borewell-fed. Big underground sumps, hard water, heavy scale. Starting ₹699.
Sainik Farms is a low-rise spread of large farmhouses and independent kothis on generous plots, with very little piped DJB reach — homes run almost entirely on borewell and stored water. That means big underground sumps feeding rooftop tanks, often 2,000L and up. The borewell water here is distinctly hard, so we routinely open tanks with thick mineral crust on the walls and a heavy sludge layer at the sump floor. Where the sump has sat uncleaned for a year or more, the sediment can be several centimetres deep.
Because these homes store a lot of water for garden pumps, staff quarters and the main house, the sumps rarely run empty, so sediment keeps accumulating undisturbed at the bottom. Summer draws down the tanks harder and concentrates minerals further. We handle the large overhead tanks plus the underground sumps with full confined-space safety gear. On borewell-heavy plots like these, a proper sump clean every six months and overhead cleaning every two to three months keeps the water usable.
For a standard 1000-litre overhead tank, the whole job takes about 90 minutes from doorbell to pack-up. Underground sumps take longer — usually 2 to 2.5 hours depending on sludge. You don’t need to provide anything: we bring our own water for the rinse, vacuums, jet pumps, food-grade disinfectant and gloves, and send before/after photos on WhatsApp.
Almost every home here stores borewell water in a large underground sump before pumping it up, and that sump is where months of sediment quietly settle. Cleaning it is confined-space work: we run a gas-meter check before anyone enters, use a harness and hard hat, and keep a standby crew member outside whose only job is to monitor. We never enter a sump without this. Sump cleaning runs ₹1,500–2,500 depending on size; the larger farmhouse sumps sit at the upper end.
With no reliable DJB line, Sainik Farms depends on borewell water that carries heavy dissolved minerals, so the rooftop tanks scale up fast and thick. On plots this size the overhead tanks are often 1,500–3,000L, which we price at ₹1,299–1,499 for the 1,001–2,000L range. Cleaning includes a food-safe descaling step before chlorine disinfection, because a plain wash cannot shift a hardened crust. We photograph the before-and-after and flag any cracked fittings or worn lids we find.
“Do you clean large farmhouse sumps here?” Yes, that’s a big part of our Sainik Farms work. Underground sump cleaning is ₹1,500–2,500 depending on size, done with full confined-space safety — gas check, harness and a standby crew member. A large sump plus overhead tanks usually takes two to three hours total.
“My whole house runs on borewell — how often should I clean?” On pure borewell supply we suggest the underground sump every six months and rooftop tanks every two to three months, because hard-water scale returns quickly. We can set you up on an annual plan covering both at a discount over one-off visits, with reminders so it doesn’t slip.
“Is there an extra charge for the Sainik Farms area?” No area surcharge. Pricing is the same as anywhere in Delhi — overhead tanks from ₹699, sumps ₹1,500–2,500. We can usually come same-day if you call before 10 AM, Sundays included, and larger multi-tank plots we quote up front on the phone.
