Our Gulshan-e-Iqbal branch

Water tank cleaning in Gulshan & Jauhar

Most buildings here share one tank between dozens of flats. We quote the whole building once, invoice the society, and give the committee a report they can put on the noticeboard.

Why shared tanks are the harder problem

Gulshan and Jauhar are apartment territory, and a shared tank behaves nothing like a household one. A single underground tank feeding forty flats is drawn down and refilled several times a day. That constant movement keeps sediment in suspension instead of letting it settle harmlessly at the bottom, and it means any contamination reaches every flat in the building at the same moment. Shared tanks need cleaning more often than single-family ones, not less.

The obstacle is almost never money. Split across the flats, a building clean is small money per household — usually far less than residents assume before anyone checks. The real obstacle is that no single resident has the authority to book it. Everyone can see the problem, nobody owns it, and it sits in the building WhatsApp group for another year.

If you are on the committee, the thing that actually moves it is a written quote addressed to the society with a date on it. That turns a group conversation into a decision somebody can approve or decline. We will give you that in writing, with the per-flat figure worked out, so you are not the one doing the arithmetic in a meeting.

One practical thing specific to this area: roof access and hatch sizes vary enormously between blocks. Some older buildings in Gulshan and Nazimabad have overhead tank openings too narrow for standard equipment. We check that on the survey rather than discovering it on the day with the building's water already drained — which is exactly how a job stalls halfway and residents end up with no supply for an evening.

Apartment blocks and societies

Shared underground and overhead tanks on a six-monthly cycle. One quote for the building, one invoice to the society, and a dated report the committee can circulate as proof the work was done.

Nazimabad and Federal B Area houses

Older properties where the underground tank is often original to the building and has frequently never been fully emptied. These take longer than a routine clean, and we quote them honestly rather than discovering it halfway.

SITE and Landhi industrial units

Factory and warehouse storage, scheduled around your shutdown rather than ours. Documented procedure and a compliance report for your audit file.

Pricing

Water tank cleaning price in Gulshan & Jauhar

You should not have to phone a company to learn a price. Ours is on the site.

See the price before you call

House prices are published: a 120 sq yd house with both tanks is Rs 4,500 and 240 sq yd is Rs 5,000. For a building, we survey free and give the committee a written total with the per-flat figure worked out — that number is usually what settles the decision.

Registrations

What you can ask us to produce

If you are approving this on behalf of a society, these are the documents to ask any contractor for. We would rather you did.

ISO 9001

Quality management. Every job follows the same documented procedure and is signed off at handover.

ISO 45001

Occupational health and safety — the standard that covers our crews entering a sealed underground tank.

SRB registered

FBR registered

Federal Board of Revenue. A numbered invoice that survives an audit.

How the job runs

How we clean tanks in Gulshan and Jauhar

Price or free survey. The tank is drained with a sludge pump, with nothing pushed back into your supply line. Underground tanks are ventilated before anyone goes in, and a second worker stays at the opening. The sludge is taken off the property, the walls are washed and scrubbed — at low pressure on fiber tanks — then disinfected with chlorine and rinsed. You check the tank before you pay, and buildings get one tax invoice made out to the society.

Questions

Tank cleaning in Gulshan & Jauhar: common questions

Who is responsible for cleaning the tank in an apartment building?
Legally it sits with whoever controls the common area — in practice the building committee or the society office, not the individual flat. That is precisely why these tanks go uncleaned for years: every resident assumes someone else owns the problem. If you are a resident, the useful move is not to argue in the WhatsApp group but to get a written quote addressed to the society with a date on it, so the committee has something to approve rather than something to discuss.
How much does it cost per flat?
Split across a building it is usually small money per household — far less than most residents expect. Shared building tanks are priced after a free survey, and we give the committee a written figure with the per-flat amount worked out. For a house, see the rates on our price page or call 0340 2717530.
Our building has one underground tank for forty flats. Is that different?
Yes, and it is worse than a household tank, not better. A shared tank is drawn down and refilled several times a day, which keeps sediment in motion rather than letting it settle harmlessly at the bottom. It also means any contamination reaches every flat in the building at the same time. Shared tanks need cleaning more often than single-family ones, not less.
The hatch on our overhead tank is very narrow. Can you still do it?
Usually yes, but we check on the survey rather than finding out on the day with your water already drained. Hatch sizes and roof access vary a lot between blocks in Gulshan and Jauhar — some older buildings have openings too narrow for standard equipment, and we carry alternatives for those. Tell us the building when you call and we will know most of them.
How quickly can you reach Gulshan, Jauhar or Nazimabad?
This branch is at Suite-203, Mumtaz Manzil, Block 16, so Gulshan, Jauhar, Nazimabad and Federal B Area are our shortest runs. For urgent jobs we can usually be on site the same day. Call 0340 2717530 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 bad air, not dirt. The tank is ventilated before entry and a second worker stays at the opening the whole time someone is inside. Large tanks also get air testing, a harness and a tripod. Most informal cleaners in this area only service accessible rooftop tanks, which is why the underground tank in an older Nazimabad or Federal B Area building has often never been fully emptied. More on safety.
Will residents lose their water supply, and for how long?
Only while the tank is drained and refilled. A rooftop tank takes two to four hours; a shared underground tank takes four to eight. We schedule around the building supply timing so the gap falls where it inconveniences residents least, and we give the committee a window they can post on the noticeboard in advance.
Can you invoice the society rather than individual residents?
Yes, and that is how most buildings here do it. We are registered with the Sindh Revenue Board and the Federal Board of Revenue, so the society gets one numbered tax invoice for the whole job, plus a dated report the committee can circulate to residents as proof the work was done.
