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

Al Andalus is a prominent central northern district on the Corniche, with spacious villas, upmarket apartments, a general hospital and international schools. Tanks here run deeper than in other areas because large villas consume more water for use and garden irrigation. High coastal humidity and salt air cause rapid algae growth and sticky biofilm on the interior walls. A team here must understand the depth of cleaning required for large villa tanks exposed to constant sea humidity.
Large villa tanks in Al Andalus run deeper and hold heavier sediment than apartment tanks, and coastal algae grows rapidly on interior walls because high humidity and warmth combine to create ideal conditions. For the method itself, see how we approach water tank cleaning.
Al Andalus villas are spacious with extensive outdoor areas and large gardens, requiring considerable water for irrigation and household use. Tanks here are deeper and larger, and cleaning needs stronger equipment and a larger team. Sediment on the floor is heavier, walls are taller, and scrubbing takes longer throughout.
Villas on the Corniche with high humidity and salt air create perfect conditions for dark green algae growth. Large quiet tanks may hold a thick algal layer on the walls where light and warmth reach. Full cleaning needs deep scrubbing and strong disinfection to remove algae completely and prevent rapid regrowth.
Upmarket villas have large gardens, fountains and continuous irrigation systems, and spray water may enter the tank through ventilation openings or shared irrigation lines. The tank may hold leaves and garden debris. Inspecting pipes and ventilation before cleaning is essential.
Al Andalus sits on Andalus Road close to the Corniche itself, with spacious villas on private plots and large gardens. High coastal humidity and salt-laden sea air accelerate the buildup of algae and minerals in large storage tanks.
In a villa district on the Corniche, the tank may hold thick green algae and salt deposits together, so we inspect closely with strong light and measure the depth of algal growth.
Draining a large villa tank requires strong equipment and safe disposal without disturbing neighbouring villas, so we manage the operation carefully.
Sediment removal from the deep tank floor takes considerable time because deposits are heavy and sand and salt are compacted deep on the bottom.
Scrubbing the walls and corners takes considerable time because the tank is deep and algae is rooted deep in the internal coating or concrete surface.
Strong disinfection is essential here because the warm humid coastal environment has created diverse bacteria and algae, so we use certified disinfectant approved for drinking water.
The final rinse takes a very long time because we must ensure no algae residue, no salt taste, no smell and no cloudiness remains before handover.
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.
Villa district: private plots, gardens and a boundary wall to every house
The villa character in Al Andalus means large outdoor spaces, gardens, swimming pools and complex irrigation systems. Large tanks may contain water from garden runoff or irrigation leakage, and high coastal humidity causes algae to form rapidly.

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.
Andalus Road and King Fahd General Hospital mark the district location clearly within the upmarket area, and when we schedule your appointment we use these landmarks to guide the team accurately to the villa within this extended district.
We provide these in Al Andalus too, and more than one can share a single visit.
