Our DHA Phase 2 branch

Water tank cleaning in DHA & Clifton

Underground RCC cisterns are what most homes here actually run on, and they are the tank most cleaners cannot enter. That is the job this branch is built around.

What tanks are actually like in DHA and Clifton

Housing here is built around large underground RCC cisterns. A bungalow on a 500-square-yard plot commonly holds five to ten thousand gallons below ground, feeding a much smaller rooftop tank. The underground tank is where sediment settles and where biofilm has the most surface to grow on — and it is the one that quietly gets skipped, because entering it needs ventilation equipment and confined-space training that most operators do not have.

This is why so many households in DHA and Clifton have their rooftop tank cleaned, see no lasting improvement, and conclude that tank cleaning does not work. It does. It was just done on the wrong tank. Water leaving a dirty underground cistern re-contaminates a spotless rooftop tank within days.

Proximity to the sea matters more than people expect. Salt-laden air corrodes tank lids, hinges and inspection covers faster in Clifton, Gizri and Seaview than further inland. A cover that no longer seats properly is the single most common way dust, insects and rainwater get into a sealed tank — and it will undo a clean in weeks. We check the lid on every job in this area and write it into the report.

Supply timing across the Phases adds one more thing. Most households run the underground tank low and then refill hard when supply arrives. That surge stirs settled sediment back into suspension right before it is pumped upstairs, which is why water often looks worse immediately after a fill rather than better. Clearing the underground tank properly fixes a problem people usually blame on the rooftop one.

Bungalows and large plots

Dual-tank setups: a large underground RCC cistern plus a smaller rooftop tank. Both get done in one visit. Cleaning only the overhead tank achieves very little, and we will say so rather than take the easier job.

Clifton apartment blocks

Shared underground storage for the whole building, usually arranged through the society. One quote, one invoice, and a report the committee can circulate to residents.

Korangi and Landhi industrial units

Large-capacity and multi-tank sites, scheduled around your shutdown. Documented procedure and a compliance report for your audit file.

How the job runs

The short version

Survey and written quote. Controlled drainage, with nothing pushed back into your supply line. Forced ventilation and a gas test before anyone enters a sealed tank. Jet washing at 3,000+ PSI to break the biofilm, at reduced pressure on fiber surfaces. All sludge vacuumed out and removed from the property. Silver-stabilised hydrogen peroxide at full contact time. Rinse until clear. Then a dated report with the photographs, and a numbered SRB/FBR invoice.

Questions

Before you book

How much does water tank cleaning cost in DHA or Clifton?
Use the calculator on our instant price page. Pick the property type, say whether the tank is underground, overhead or both, and give the size in gallons or plot square yards — you get the figure straight away. Most DHA bungalows have a dual setup, so price both tanks together rather than the rooftop one alone. Larger or unusual properties get a free survey first, and the quote you are given is the price you pay.
My rooftop tank was cleaned recently but the water still looks bad. Why?
Almost always because the underground tank was not touched. In DHA and Clifton the underground RCC cistern is usually several times larger than the rooftop tank, and it feeds it. Cleaning the small tank downstream of a dirty large one buys you a few days. Ask whoever cleaned it whether they entered the underground tank — if they did not have ventilation equipment, they did not.
How quickly can you reach DHA or Clifton?
This branch is at Office-6, Plot-6-C, Phase 2, so DHA, Clifton, Gizri and Saddar are our shortest runs. For urgent jobs we can usually be on site the same day. Call 0333 0293174 and we will give you an honest arrival window rather than a hopeful one.
Do you clean underground RCC tanks, and is it safe?
Yes, and it is the part of this job that actually matters. An underground tank is a confined space — the real hazard is oxygen depletion, not dirt. We run forced ventilation, gas test the atmosphere before entry, use a harness and tripod, and keep an attendant at the hatch for the whole time someone is inside. Most informal cleaners in Karachi only service accessible rooftop tanks, which is why underground tanks in this area routinely go years without a proper clean.
Will my water be cut off, and for how long?
Only while the tank is drained and refilled. A rooftop tank takes two to four hours. A large underground RCC cistern takes four to eight. We schedule around your supply timing so the gap falls where it costs you least — for most DHA households that means starting early on a non-supply day.
Can you check the tank lid and cover while you are there?
We check it on every job here and note it in the report. Sea air corrodes lids, hinges and inspection covers faster in DHA, Clifton and Seaview than further inland, and a lid that no longer seats properly is the most common route for dust, insects and rainwater to get into a tank you just paid to clean. If yours needs replacing we will tell you — we do not sell them.
Do you invoice properly for a building or a company?
Yes. We are registered with the Sindh Revenue Board and the Federal Board of Revenue, so you get a numbered tax invoice. Clifton apartment societies, Korangi factories and Saddar commercial buildings use it directly in their accounts.
