Water Tank Cleaning in Rawalpindi

Water Tank Cleaning in Rawalpindi

Rawalpindi water supply situation varies considerably by area. Central areas including Saddar and Cantt receive municipal supply through older infrastructure that carries more sediment. Bahria Town Rawalpindi has its own water treatment plant which generally delivers cleaner water but still requires tank maintenance.

Many Rawalpindi households receive water by tanker — particularly in areas where municipal supply is insufficient or unreliable. Tanker water quality varies significantly by supplier and the cleanliness of the tanker itself, which means tank sediment buildup is often faster for tanker-supplied households. We recommend cleaning every 4 months for households primarily on tanker supply.

Overhead rooftop tanks in Rawalpindi are exposed to intense summer heat — temperatures inside a plastic rooftop tank in July can exceed 60°C, which accelerates biofilm growth considerably. Tanks in direct sun should be cleaned every 3 to 4 months during the hotter part of the year.

What Happens If a Tank Is Not Cleaned?

Symptoms that suggest the tank needs urgent cleaning: water that smells earthy or musty, visible sediment at the tap, or unexplained stomach issues in household members. Any of these warrant cleaning within the week rather than at the next scheduled interval.

• Sediment accumulates at the tank base and eventually enters the plumbing, clogging fixtures and filters
• Biofilm on tank walls produces compounds that cause odor and taste changes in water
• Pathogenic bacteria can colonize the biofilm and contaminate drinking water supply
• Algae growth in tanks exposed to light produces toxins and changes water color
• Float valve and inlet mechanisms can clog with sediment, affecting tank refill
