Professional underground RCC & overhead plastic tank cleaning across all Landhi sectors — from Landhi Colony to Quaidabad, Bhains Colony, and the industrial zone. Certified team, WHO-approved disinfectants, transparent pricing — same-day slots available 7 days a week.
Landhi is one of Karachi's largest and most densely populated districts, stretching across a vast area in the city's east that includes Landhi Colony's many sectors, the sprawling Quaidabad settlement, Bhains Colony, Sharafi Goth, and one of the country's most significant industrial corridors. The sheer variety of property types here — from compact katchi abadi homes to large factory premises and multi-storey colony apartments — means water tank maintenance needs are equally diverse and often more urgent than in other parts of Karachi.
Water supply to much of Landhi comes via long distribution lines that carry elevated sediment loads by the time they reach storage tanks. In Landhi Colony's residential sectors, underground RCC tanks are the norm and frequently suffer from years of accumulated sludge, bacterial biofilm, and calcium deposits from Karachi's hard water. For homes near the industrial areas of Landhi and Korangi, there is an additional risk: airborne particulates from nearby factories settle into uncovered or poorly sealed overhead tanks, adding industrial dust and contaminants to the usual biological growth.
We have been serving Landhi consistently since 2007. Our teams are familiar with the locality's layout, its tank construction standards, and the specific water quality concerns affecting different pockets of the area — from the older housing blocks of Landhi Colony to the newer construction in Quaidabad.
Landhi's industrial environment and long water supply lines create specific contamination risks. Know when to act.
In Landhi, a chemical or sewage odour from taps can indicate either bacterial contamination inside your tank or industrial particulate contamination of an overhead tank. Either way, stop using the water and call us immediately.
🚨 UrgentDiscoloured water coming from taps in Landhi homes is almost always sediment disturbed from the bottom of an underground RCC tank. Heavy sediment at this level means serious buildup — clean immediately.
🚨 UrgentTyphoid, gastroenteritis, and waterborne illness is a persistent risk in high-density areas of Landhi. If members of your household have recurring stomach complaints, contaminated tank water is a primary suspect.
🚨 UrgentProperties near Landhi and Korangi industrial areas often find fine dust and grit in their rooftop plastic tanks — especially in the dry winter months when industrial particulates are higher. Inspect and clean your overhead tank if you notice sandy residue from taps.
⚠️ WarningAlgae visible on the inner walls of your overhead tank when you open the lid is a clear sign of overdue cleaning. Algae in your water supply is a direct health risk — do not delay.
⚠️ WarningIn Landhi, where water supply sediment levels are higher than in many other Karachi areas, annual cleaning is the absolute minimum. If it's been longer, the sediment and bacterial load in your tank is almost certainly at a hazardous level.
⚠️ WarningKarachi's monsoon flushes elevated sediment and contaminants into the water supply. In Landhi, where the water table is also affected by nearby industrial discharge, post-monsoon tank inspection is strongly recommended every year.
👁 WatchWhen taking a new property in Landhi Colony, Quaidabad, or Bhains Colony, you have no history of the previous occupant's tank maintenance. Start clean — an inspection and cleaning before moving in is essential.
👁 WatchAn unusual taste in your water — metallic, earthy, or musty — separate from typical KW&SB supply characteristics often indicates biofilm developing inside the tank. This is the stage before smell, and the ideal time to clean before conditions worsen.
👁 WatchComplete water tank cleaning for every property type in Landhi — from colony homes to factories and apartment blocks.
Underground reinforced concrete tanks dominate Landhi Colony's older residential sectors. We drain the tank completely, manually scrub all concrete surfaces to remove sludge, sediment, and biofilm, apply high-pressure jet washing, disinfect with WHO-approved chemicals, rinse thoroughly, and issue a completion certificate. We handle tanks from 500 to 5,000+ gallons in Landhi's diverse housing stock.
Rooftop plastic tanks in Landhi face a dual threat — summer sun accelerates algae growth, while proximity to the industrial zone means dust and particulate contamination of uncovered or poorly sealed tanks. We clean all sizes of overhead tanks, scrubbing internal walls, removing algae and grit, and disinfecting completely. Particularly important for homes near the Landhi and Korangi industrial corridors.
Landhi's industrial area is home to textile factories, food processing plants, and large manufacturing facilities — all of which require clean water storage for operations and staff welfare. We clean industrial-scale concrete sumps, rooftop tanks, and large water storage units. Service certificates are provided for health department, EOBI, and factory compliance. A free site survey is required before quoting for industrial jobs — call 0313-2796778.

Landhi is not one neighbourhood — it's a patchwork of colonies, goths, and industrial zones, each with different tank types and water challenges.
Landhi Colony is the heart of the area — a planned residential settlement with numbered sectors (1 through 6 and beyond) that was developed for factory workers originally employed in the adjacent industrial zone. The housing stock is predominantly low-to-mid-rise buildings from the 1960s through 1990s, with underground RCC tanks that are now decades old. Many of these tanks have not been properly cleaned in years and contain heavy sediment accumulation and bacterial contamination. Our teams are experienced with the compact plot sizes and alley access patterns common in Landhi Colony, allowing efficient deployment even in tightly built sectors.
🔧 Deep-clean RCC specialistsQuaidabad is one of the largest and most densely populated localities adjacent to Landhi, with a mix of katchi abadi settlements and more organised residential blocks. Water pressure in Quaidabad is frequently low, meaning tanks are often emptied to low levels before refilling — concentrating sediment at the bottom with every cycle. This accelerates contamination buildup significantly compared to areas with better pressure. Residents here particularly benefit from the 6-month cleaning schedule rather than annual — the sediment cycling in low-pressure zones creates conditions for rapid bacterial growth.
⚠️ Bi-annual cleaning recommendedBhains Colony — Karachi's main urban dairy farming area — presents unique water quality challenges. The area's proximity to livestock and the specific waste profile of a working dairy colony means groundwater contamination risk is higher than in purely residential zones. Residents here should ensure their underground tanks are well-sealed and cleaned regularly. Our team is experienced with the types of tanks commonly found in Bhains Colony and approaches each job with the additional care warranted by the area's environmental conditions.
🔒 Sealed-tank inspection includedThe Landhi–Korangi industrial corridor is home to hundreds of textile mills, food factories, pharmaceutical plants, and light manufacturing units. Industrial facilities require water storage cleaning for multiple purposes: drinking water tanks for workers, process water tanks, and fire suppression reserves. Compliance documentation is frequently required for EOBI inspections, health department visits, and factory audits. We provide full service certificates for industrial clients and have the capacity to clean large-volume industrial tanks that typical residential tank cleaners cannot handle. Contact us for a free site survey.
📋 Factory compliance certificates issuedThe same rigorous process on every Landhi job. No shortcuts on any step.
Our technician inspects your tank — assesses condition, measures capacity, identifies structural issues or contamination severity. Final price confirmed with you before any work starts.
Tank is fully drained using our pump equipment. Complete drainage is non-negotiable — partial draining leaves sediment behind and prevents proper wall scrubbing.
All internal surfaces — walls, floor, corners, and ceiling where accessible — are manually scrubbed to remove sludge, sediment, biofilm, algae, and mineral deposits. No machine substitute for this step.
High-pressure jet washing flushes all loosened debris out of the tank. WHO-approved disinfectant is then applied to all surfaces and held for the correct contact time before final rinse.
Tank is refilled and a service completion certificate issued — documenting date, tank size, chemicals used, and technician. Valid for factory audits, health department visits, and building management records.
Pricing depends on your tank size, type, and the number of tanks at your Landhi property. Use the online calculator for an instant residential estimate. For industrial or commercial tanks in Landhi's factory zone, call us for a free site survey.

Real feedback from Landhi residents, building managers, and factory owners.
"Our underground tank in Landhi Colony Sector 3 hadn't been touched in two years. When they drained it, the sludge at the bottom was almost ankle-deep. The team scrubbed it clean, used proper disinfectant, and gave us a certificate. Water quality improved immediately. Will book every 6 months going forward."
"We run a garments factory in Landhi Industrial Area and needed our worker drinking water tanks cleaned for a compliance inspection. Karachi Tank Cleaning arrived on time, cleaned four tanks in a single day, and gave us the service certificate we needed. Inspectors were satisfied. Highly recommend for industrial clients."
"Called on Saturday morning — water from our taps in Quaidabad had gone brown. They responded within 3 hours, found serious sediment in the RCC tank, cleaned it completely. Honest about what they found, no price changes from the initial quote. That kind of reliability is rare in this area."
