Eta is a settled plotted pocket of Greater Noida — rows of independent kothis on generous plots, most with a sizeable underground sump and a rooftop overhead tank. We clean both, on the big independent houses of Eta, Greater Noida, from ₹699 onwards.
Eta sits in the planned-city grid of Greater Noida as a largely plotted residential pocket, its wide roads lined with established independent kothis rather than apartment towers. These are family homes on generous plots, and most run a roomy underground sump at ground level paired with one or more overhead tanks on the roof. Water arrives on piped Ganga supply with borewell backup, and on a big plot the storage capacity is large — which means more water sitting still between fills and more surface for sediment to settle on. The borewell groundwater runs hard here too, so a chalky scale builds on the walls on top of the usual silt.
The catch in a roomy kothi is that the bigger the sump, the easier it is to put off cleaning — it feels like a major job, so it waits, sometimes for years. All the while sediment, biofilm and mineral scale collect on the floor and walls, and because the overhead tank is filled from that sump, the grime travels up to the taps of an otherwise immaculate house. We do the full job on an Eta kothi: the large underground sump and the rooftop overhead tank together, so the whole line is genuinely clean. On a big plot the sump is the part that pays off most to do properly, and you see the before-and-after on both.
On an Eta plot the real clean is two parts — the big underground sump and the roof overhead tank. We drain the sump, scrub the walls and floor by hand to lift the settled silt and the hard-water scale a large sump always holds, then vacuum out the loosened sludge, disinfect with food-grade chlorine and rinse. We do the overhead tank the same way, so nothing dirty carries up the line into the house. On generous plots there is more surface and more sediment, so the thorough method matters. You see clear before-and-after on both tanks before we finish.
An individual overhead tank starts at ₹699 and takes about 90 minutes; a large sump on a roomy plot is a bigger job, priced by size and how much sludge has built up. We quote on sight before any work begins, so there is no guesswork. Doing the sump and tank together in one visit is the sensible way to handle a big Eta kothi, and the crew comes uniformed with its own pump and vacuum gear.
Standard Eta tank: about 90 minutes door-to-door for an overhead tank, 2-3 hours for a combined sump + overhead, and longer for high-rise society reservoirs. We bring everything — vacuums, jet pumps, food-grade chlorine disinfectant, scrubbing brushes, rinse water. After cleaning, before-and-after WhatsApp photos and a GST invoice.
"Our Eta kothi has a large sump that hasn’t been cleaned in years — can you handle it?" Yes, and on the big plots in Eta that is common, because a roomy sump feels like a major job and gets put off. Years of silt, sludge and hard-water scale settle on the floor, and since the overhead tank fills from it, that grime reaches your taps. We drain, scrub, vacuum the sludge and disinfect with food-grade chlorine, then show before-and-after. A large sump is priced higher than an overhead tank by size, quoted on sight. Call 95603 66362.
"Should the overhead tank and sump be cleaned together?" On an Eta plot, yes — it is the sensible way. The overhead tank is filled from the sump, so cleaning one without the other leaves half the line dirty. Done together in one visit it is cheaper than two separate trips. The overhead tank is from ₹699 and the sump is priced by size and sludge. We show before-and-after on both so you can see the job was done properly. Call 95603 66362.
"How soon can you reach Eta in Greater Noida?" Usually same-day if you call before noon, as Eta is easy for our crews to get to on the planned-city roads. A single overhead tank is about 90 minutes from ₹699; a large sump-and-tank job on a big plot runs longer and we give you the window when you book. Call 95603 66362 for a realistic time.
