PECHS — Pakistan Employees Cooperative Housing Society — is one of Karachi's most established middle-to-upper-middle-class residential neighbourhoods, laid out in a planned grid of numbered blocks between Tariq Road to the north and Tipu Sultan Road and Shaheed-e-Millat Road to the south. It sits between Bahadurabad, PECHS Society, and the Nursery area, and is characterised by a mix of traditional bungalows, increasingly converted apartment buildings, and a dense commercial strip along its boundary roads.
The defining tank challenge in PECHS is the area's transition from a bungalow-dominant neighbourhood to one with a growing number of multi-storey apartment constructions. Many PECHS bungalows — particularly on 200 to 400 sq yard plots in Blocks 2, 3, and 6 — have large underground RCC tanks built 20 to 35 years ago that have rarely if ever been professionally cleaned. These tanks, combined with one or two overhead plastic tanks, are the standard residential setup here, and the combined cleaning package is by far our most common booking in PECHS.
Water quality in PECHS benefits from its relatively central location in Karachi's supply network, but the sediment and bacteria load in municipal supply is still significant enough to cause rapid buildup in uncleaned tanks. Families that have not cleaned in over a year are typically living with water that fails basic cleanliness standards — even when the water looks and smells acceptable to the naked eye.
PECHS bungalows and apartments are often on the same water tank for years without a proper clean. These are the warning signs you should never ignore.
Active bacterial or algae contamination already in your water supply. In a PECHS bungalow with a large underground RCC tank, this can affect an entire household. Call for same-day emergency service — don't use the water.
Typhoid, gastroenteritis, and skin infections from contaminated tank water are common in Karachi. If your family has had recurring illness with no other obvious cause, your underground tank is the first place to check.
Visible discoloration almost always points to sediment buildup in the underground tank rather than the supply line. In older PECHS bungalows where tanks haven't been high-pressure washed in years, this is the most common symptom we see.
Any visible growth around the tank opening or on interior walls means contamination is established. Overhead plastic tanks in PECHS rooftops exposed to sunlight are particularly prone to algae growth — often developing within 3–4 months of the last clean.
Sediment accumulation at the base of an underground tank restricts flow through the outlet pipe. This is commonly misread as a pump problem in PECHS homes — but draining and cleaning the tank usually resolves it without any pump work needed.
For most PECHS residential properties, 6 months is the maximum safe interval — even when water appears clear and odourless. Underground RCC tanks in particular accumulate biofilm on their walls long before visible symptoms appear. Book a preventive clean before you need an emergency one.
Every tank type found across PECHS's bungalows, apartment buildings, and commercial properties — handled by experienced, fully equipped technicians.
Full drain, high-pressure jet wash, manual scrubbing, and WHO-grade disinfection of underground RCC tanks. The standard setup in PECHS bungalows is a brick-reinforced concrete underground tank ranging from 800 to 3,000 gallons. Many of these have not been professionally cleaned in years and require intensive treatment — our team is equipped for it.

PECHS is not uniform. The tank situation in a Block 2 bungalow is completely different from a converted Block 6 apartment or a Tipu Sultan Road commercial unit. Here's what we typically encounter across the area.
Blocks 2 and 3 are PECHS at its most traditional — planned bungalow plots from 120 to 400 sq yards, with most properties having a dedicated underground RCC tank plus one or two overhead plastic tanks. Many of these underground tanks were constructed in the 1980s and early 1990s and have been in continuous use since. The combined cleaning package is the standard here, and the underground tank inspection on first service frequently reveals years of accumulated sediment and algae that the owner was entirely unaware of.
🧮 Instant estimate available onlineBlock 6 is where PECHS's transition is most visible — original bungalows sitting alongside newly built 4 to 8-storey apartment blocks. The apartment buildings typically have large shared underground tanks serving all floors, and these are almost always commercial-size jobs that need a site survey before quoting. For original bungalows in Block 6, the same combined underground + overhead service applies. We see both property types weekly in this block.
🔍 Apartments need survey firstTipu Sultan Road is PECHS's main commercial and institutional artery — lined with private hospitals, clinics, schools, banks, restaurants, and offices. Commercial properties here are legally required to maintain clean water storage for staff and patients, and health department compliance is a real concern for medical facilities in particular. We service several Tipu Sultan Road businesses on regular cleaning contracts. All commercial tanks require a free site survey before quoting.
🔍 Commercial survey requiredThe Nursery area and the Shaheed-e-Millat Road corridor form PECHS's southern and south-eastern boundary, with a mix of residential side streets and a commercial strip. Properties here are a combination of older homes, newer constructions, and converted commercial units. Overhead tanks in this zone are often exposed to the full afternoon sun, which accelerates algae growth in summer — particularly in south-facing plastic tanks that heat up significantly. We recommend more frequent cleaning (every 4–5 months) for rooftop tanks with heavy sun exposure.
⚠️ Sun-exposed tanks need more frequent cleaningWe've been operating in Karachi since 2007. Here's what distinguishes a professional service from the informal options you'll find on a WhatsApp group.

A legitimate, documented company that provides proper tax invoices. Essential for PECHS commercial clients — clinics, schools, restaurants, and offices — who need documented maintenance records for compliance or audits.
Technician inspects your tank thoroughly before starting work. Identifies the actual condition, confirms what needs to be done, and quotes the final price. No obligation to proceed if you're not comfortable with the assessment.
Real feedback from PECHS residents and businesses who have used our service.
"We have a 240 sq yard bungalow in PECHS Block 2 with a large underground RCC tank. First time getting it professionally cleaned in over 10 years — the team drained it and showed us the state of the inside before cleaning. Couldn't believe what we'd been drinking. Excellent, thorough work."
"We run a private clinic on Tipu Sultan Road and use Karachi Tank Cleaning every 6 months. They provide a proper invoice for our compliance records and the team is always professional and punctual. For a medical facility, water hygiene is non-negotiable — these people take it as seriously as we do."
"Called them on a Saturday morning for an emergency — water had turned yellowish in Block 6. They arrived within 3 hours, found a completely sludge-filled underground tank, cleaned it properly, and the water was clear again by evening. Excellent response time and the team was polite and professional throughout."
