The right gear for drinking water
Pumps to clear sludge, scrubbing to remove biofilm, and disinfectant meant for potable storage.

Al Rayyan is an east Jeddah district far from the sea with apartment blocks sitting on wide streets marked by ongoing sewage and water infrastructure work not yet finished. Water carries grey dust from road and pipe digging, and the tank itself fills with fine sand and grit from the open ground.
Tanks in Al Rayyan receive fine heavy sand from ongoing excavation, and grey sediment heavier than in coastal areas settles and coats the tank bottom. For the method itself, see our guide to water tank cleaning.
Ongoing infrastructure work raises heavy grey dust that enters through ventilation points and small cracks. The dust mixes with air moisture and creates thick grey sediment in the tank. Suctioning grey deposits needs strong power because they are heavy and not oily.
Tanks on open roofs in a district under construction hold wind blown sand and building dust. This settles at the tank bottom and leaves a grey film in any tap or basin. Full draining and vacuuming clean the tank, and fresh water will not leave grey stains.
Infrastructure work cuts or damages pipes, and pressure may drop. A tank full of heavy sediment may add to the weakness because sediment clogs the outlet openings. Full cleaning removes the sediment and improves water flow.
A district in east Jeddah far from the coast and close to open ground and hills, apartment blocks on wide streets, and ongoing sanitation and infrastructure work with roads left open and trenches still being cut.
The tank may hold a thick grey layer from ongoing excavation, and we inspect it first to assess the depth of grey sediment.
Draining in a district under construction means we may need to dispose of grey water safely away from active digging sites.
Suction needs extra power to shift sand and grit that is heavy and does not spread like oily sediment.
Hand scrubbing removes the grey film from tank walls, and may take time because sandy deposits are hard.
Disinfection kills bacteria in sandy sediment, and needs time to spread fully through the tank.
Final rinsing removes remaining fine sand and disinfectant, and lid check confirms it is sealed tight against fresh dust from ongoing work.
The supply into the tank is shut and the tank is drained completely.
The sludge on the floor is scooped and pumped out first.
The biofilm on the walls is physically scrubbed off.
With the walls and floor clean, a disinfectant made for drinking-water storage is applied and given time to act on every surface.
The disinfectant and any loosened residue are rinsed down and pumped out, so the first tank of water after us is not carrying it.
We check the cover seal and inlet before refilling, so dust and insects stay out, then start the refill while you watch it run clear.
The Air Base Bridge marks Al Rayyan clearly, and Al Thuraya Scheme and Al Sultan Scheme divide the district into recognisable areas, making it easy for our team to reach sites and coordinate with residents at times when digging and heavy traffic are at their quietest.
Pumps to clear sludge, scrubbing to remove biofilm, and disinfectant meant for potable storage.
We send a team, not one person, so a tank is drained, cleaned, disinfected and refilled in a single visit rather than left open for days.
We look at the lid seal and inlet, because a tank that got dirty fast usually has a way in.
Nothing is closed until the tank is refilling and you have seen the water run clean.

The commitment is simple enough to actually keep: we do not leave until the tank is disinfected, refilling, and you have seen it for yourself.
East Jeddah lies furthest from the sea and closest to the open ground and hills beyond the ring roads, so the air is drier and the dust is coarser and paler than on the coast. It comes in under doors and settles on every flat surface overnight, making sofas, mattresses and curtains the heaviest part of the routine. Floors are mostly ceramic tile in the apartment districts and marble in the villa areas, both scratched by grit that is mopped rather than swept. Roof tank water leaves a grey film of sediment in baths and basins.
We provide these in Al Rayyan too, and more than one can share a single visit.
