Orangi Town is one of the largest urban settlements in the world by population, stretching across more than 20 sectors in north-western Karachi. With an estimated population of well over two million people living in densely packed residential streets, water supply is one of the most critical daily concerns — and water storage hygiene is directly tied to the health of every household that depends on stored tank water.
Unlike more centrally served areas of Karachi, many parts of Orangi Town rely heavily on tanker water supply during dry periods, storing large volumes in underground RCC tanks before pumping to overhead plastic tanks. This frequent cycling of water — drawn from tankers, stored underground, pumped up, and held in rooftop tanks — creates multiple points where sediment, bacteria, and algae can accumulate. Tanks that aren't cleaned every 6 months become a direct source of waterborne illness, including typhoid and dysentery, which are preventable with regular professional cleaning.
Our team covers all of Orangi Town — from the inner sectors near Banaras Chowk to the outer sectors bordering Baldia Town and North Karachi. We handle everything from a single 200-gallon overhead plastic tank in a row house to large shared underground tanks in multi-storey buildings across Mominabad and Qasba Colony.
In Orangi Town, where tanker water supply is common and tanks cycle frequently, contamination can develop faster than you'd expect. Watch for these signs.
Active bacterial or algae contamination in your underground or overhead tank. In Orangi Town's high-usage tanks, this can develop quickly. Call for same-day emergency service — do not delay.
Typhoid and gastroenteritis from contaminated stored water are a known health risk in densely populated areas. If multiple family members keep falling ill, your tank should be the first thing inspected.
Sediment and rust from tanker water that has settled in the bottom of your underground tank. Common in Orangi Town properties that receive irregular tanker supply — the tank needs draining and scrubbing.
Algae growth on the tank walls or around the lid means the problem is well established. Overhead plastic tanks left in direct sunlight in Orangi's rooftop conditions are especially vulnerable to this.
Heavy sludge at the bottom of the underground tank or a blocked outflow pipe reduces pressure throughout the house. This is one of the earliest warning signs before water visibly changes colour or smell.
For Orangi Town households — particularly those receiving tanker water — 6 months is the maximum safe interval. Tanker water often carries more sediment and particulate matter than municipal line supply, accelerating buildup inside the tank even when the water appears clean at the tap.
Every tank type found across Orangi Town's sectors — handled by trained, fully equipped technicians.
Complete drain, high-pressure jet wash, manual scrubbing, and WHO-grade disinfection of underground RCC and cement tanks. The primary storage unit across most Orangi Town properties — and the one most prone to sediment accumulation when tanker water is the main supply source.

Orangi Town spans a vast area with varied housing types and water supply situations. Here's what we encounter across the main zones.
The inner sectors near Banaras Chowk and the old Orangi town centre are among the most densely settled, with tightly packed row houses built on narrow plots. Underground RCC tanks here are typically older, with porous brick-and-mortar walls that harbour biofilm more readily than newer smooth-finish concrete. Many of these tanks were built by the households themselves during the 1960s and 70s and have rarely been professionally cleaned. The sludge buildup we find in these tanks is often severe — hardened sediment layers at the bottom and dark algae on all four walls. We bring specialist scraping tools for these jobs.
⚠️ Recommend cleaning every 4–6 monthsThe mid-belt of Orangi Town sees a mix of older row houses and newer three-to-four-storey apartment buildings. Shared underground tanks in these apartment structures — typically serving 4 to 12 households — are the most common service request in this zone. Building owners often have these tanks cleaned only when there's a visible problem, by which time the contamination is significant. We recommend scheduling regular bi-annual cleaning with building management rather than waiting for complaints, and offer discounted rates for repeat-schedule bookings.
🔍 Free survey for apartment buildingsScattered across several inner and mid sectors of Orangi Town are small textile workshops, dyeing units, garment factories, and other small-scale industrial premises. These facilities often have dedicated water storage for production processes separate from the domestic supply. Industrial water tanks — used for cooling, dyeing, or washing — require cleaning on a different schedule to residential tanks, and the process differs based on what the water is used for. We assess each industrial tank on a free site survey before quoting or starting work.
🔍 Industrial survey requiredMominabad and Qasba Colony have historically experienced more irregular municipal water supply than the inner sectors, making tanker water a regular supplement for thousands of households. Tanker water carries significantly more sediment than treated municipal supply — visible as a fine brown or grey layer that settles quickly to the bottom of the underground tank. Properties in these areas that rely on tanker water should clean their underground tanks every 4–5 months rather than waiting the full 6, as the sediment accumulation rate is noticeably higher.

Real feedback from Orangi Town households and property owners.
"We've been getting tanker water for years and never cleaned the underground tank — I didn't realise how bad it had gotten until the team opened it and showed me. The sludge was almost 6 inches deep. They cleaned it completely in under 4 hours. Water quality is noticeably better now."
"I manage a 5-storey building in Mominabad. The shared underground tank serves 18 families. Karachi Tank Cleaning handled the whole job professionally — came early morning, finished before noon, gave us a proper certificate. The building committee is very satisfied. We've booked them for every 6 months."
"Called them for an emergency — smell from the tap on a Friday evening. They were at our home in Qasba Colony within 3 hours. Found algae contamination in both the underground and overhead tanks, cleaned and disinfected everything that night. Fair price and no drama. Highly recommended."
