Professional underground RCC and overhead plastic tank cleaning across all Gulshan-e-Maymar sectors. Certified team, WHO-approved disinfectants, transparent pricing — same-day slots available 7 days a week.
Gulshan-e-Maymar is one of Karachi's largest planned residential townships, stretching along the Hub River Road corridor in the north of the city. Developed across more than a dozen lettered sectors — from Sector R in the older parts of the township to the newer Sector BB and CC — it is home to hundreds of thousands of residents living in a mix of single-storey bungalows, double-storey homes, and increasingly, multi-storey apartment buildings.
Water supply in Gulshan-e-Maymar is primarily dependent on KWSB tanker deliveries and intermittent municipal supply lines, which means underground storage tanks here bear a heavier load than in most other Karachi neighbourhoods. Tanks are frequently filled from water that has already travelled long distances through ageing infrastructure — arriving with suspended sediment, residual chlorine, and in some cases low-level bacterial contamination. When that water sits in an uncleaned tank for 6–12 months, the sediment accumulates at the base, biofilm forms on the walls, and by the time discolouration or smell is noticed, the contamination is already significant.
Our team operates across all sectors of Gulshan-e-Maymar regularly and understands the specific tank configurations common here — predominantly large-capacity underground RCC tanks serving full-floor families, and overhead plastic tanks mounted on rooftops of bungalows and low-rise buildings. We clean both types, issue a service certificate on completion, and use only food-safe disinfectants approved by the WHO.
These are the warning signs Maymar residents most commonly report before calling us. Don't wait for your family to fall sick.
A foul odour in running water means active bacterial contamination in your tank. This is the one sign that requires a same-day response — do not delay.
Contaminated tank water is one of the leading causes of typhoid and gastroenteritis in Karachi. If multiple family members are repeatedly falling sick, the tank is the first place to check.
Discolouration indicates sediment, algae, or rust particles sitting in your underground tank. The problem is in your storage, not the supply line.
In Gulshan-e-Maymar, where tanker water is the primary fill source for many households, sediment builds up faster than in areas with direct KWSB line supply. A 12-month gap is already overdue.
Algae or mould growth is visible when your tank is opened. This is a clear sign of biological contamination that needs professional scrubbing and disinfection immediately.
Even if water looks and smells fine, bacterial loads can build up without visible signs. Six months is the recommended cleaning cycle — don't wait for symptoms.
Karachi's monsoon season brings surface water ingress into underground tanks, especially in low-lying Maymar sectors. Clean your tank before and after the monsoon each year.

Different parts of Maymar have different housing types, tank sizes, and water supply conditions. Our team understands these differences.
These are the original lettered sectors of Gulshan-e-Maymar where most plots were developed in the 1990s and early 2000s. Housing is predominantly single and double-storey bungalows with large underground RCC storage tanks — many installed 15–20 years ago. The older cement tanks in this zone are more prone to cracking and calcium build-up on the walls, making periodic professional cleaning essential. Our team brings the right tools for heavily soiled RCC tanks and can also advise on any visible structural concerns.
Older RCC tanks — heavy sediment commonThese sectors represent the bulk of Gulshan-e-Maymar's dense residential population. The housing mix is more varied here — bungalows, row houses, and a growing number of 4–6 storey apartment buildings. Many of the newer apartment structures have large shared underground tanks serving 8–16 flats, which require coordinated cleaning with building management. Overhead plastic tanks are common in older bungalows in this zone. We handle both configurations and have ongoing relationships with several building managers in these sectors.
Apartments & bungalows — mixed tank typesThe newer sectors of Gulshan-e-Maymar are undergoing rapid residential development, with freshly built bungalows and multi-storey buildings on recently allotted plots. Even in newer constructions, water tanks need cleaning within the first 1–2 years of use — construction debris, dust, and paint residue from the building process frequently enters tanks during installation. First-time cleaning after construction is especially important to establish a clean baseline before regular maintenance cycles begin.
New construction — post-build cleaning neededEvery service includes a free inspection, WHO-approved disinfection, and a completion certificate.

Real feedback from real Maymar residents and property managers.
"Our underground tank in Sector T had not been properly cleaned in years — the water had a faint smell and there was visible sludge at the base when we finally opened it. The team from Karachi Tank Cleaning drained it completely, scrubbed the walls, and disinfected everything. Water has been perfectly clear and odour-free since. Will call them again in six months."
"We manage a 5-storey building in Sector X with a large shared underground tank. These are always tricky to coordinate with so many families involved. Karachi Tank Cleaning handled the job professionally — came early morning before residents needed water, completed the job in 4 hours, and provided a proper certificate. Already booked them for our next cycle."
"Called on a Saturday after noticing yellowish water from the taps — a sign I had seen before and kept ignoring. They came the same afternoon. The tank had heavy sediment and algae on the walls. After the cleaning, the difference was immediate. The technician also told me about the crack at one corner — something I hadn't noticed. Genuinely professional service."
