Water Tank Cleaning & Disinfection in Nairobi
Safe, clean stored water with sludge removal, disinfection, and inspection, plus scheduled contracts for landlords and institutions.
Stored water collects sediment, rust, algae, and sometimes dead insects or rodents. Over time this causes odour, discoloured water, blocked taps, and health risks, especially in schools, hospitals, and food businesses. Our team drains the tank, removes sludge, scrubs and disinfects the walls, flushes the lines, and inspects the tank for leaks and damage before refilling.
What we do
Drain & desludge
Pump out remaining water and remove sediment and sludge without damaging the tank.
Scrub & disinfect
Scrub the walls and floor and disinfect with approved, food-safe chlorine solutions.
Inspect & report
Check for cracks, UV damage, rust, faulty floats, and missing lids, with a written report.
Flush & refill
Flush the outlet lines, refill, and confirm the water is clear and odour-free.
Water quality testing
Optional testing for chlorine residual, turbidity, and bacteria, for compliance records.
Scheduled contracts
Quarterly or six-monthly cleaning for apartments, schools, hospitals, hotels, and estates.
