Water tank cleaning and sterilising in Al Qawzain, Jeddah

Al Qawzain is a small seaside village on the southern corniche with rest houses and an open beach near a sewage treatment works and an iron factory. Tanks here face a two front salt and humidity assault compounded by trace industrial air: salt air drives accelerated corrosion while constant humidity speeds algae proliferation.

Why a clean tank matters for your water supply

A coastal strip on the southern corniche near an industrial area, with seaside rest houses and public beach access, exposed to year-round high humidity and salt air.

Seasonal maintenance before peak use

Sediment in coastal tanks mixes with algae and salt deposits, making tank bottom cleaning complex and requiring careful scrubbing technique.
After a long property vacancy

After the rest house or seaside property stands empty for a time, the tank may be thick with algae and water will emerge green or brown in colour.
Visible discolouration or unusual taste

Before the holiday season and entertaining guests, tank cleaning is essential to welcome visitors with confidence in water safety.
Landlord or building inspection requirements

Environmental regulations may require regular tank inspection in coastal areas because of proximity to the sea and industrial activity.

What changes about water tank cleaning and sterilising in Al Qawzain

Coastal tanks in Al Qawzain rust visibly on the outside quickly, and algae grows in varying colours depending on species, giving water an unusual colour. For the whole method, see our water tank cleaning and sterilising service.

The first reason
Salt air corrodes tank covers and metal fast

Strong salt air at Al Qawzain causes very rapid rust on tank metal and covers. Metal support structures can weaken noticeably in a short time, and the cover may fail to seal properly after even brief exposure.
The second reason
High humidity and summer heat fuel algae blooms

Constant coastal humidity combined with intense summer heat create perfect conditions for algae in multiple species. Algae can appear red, green or brown depending on conditions and dominant species.
The third reason
Nearby factory and treatment works affect air quality

Proximity to an iron factory and sewage treatment station may mean the air carries trace contaminants. Although the distance is short, this can influence the quality of air surrounding the tank.

What you have when the work is done

Interior walls free of scale

The scrubbing stage removes deposited minerals and biofilm from every reachable surface.

Sterilant applied and flushed out

A drinking-water-safe sterilising solution is applied to all interior surfaces and then fully flushed before the hatch is sealed.

Hatch secured and sealed

The hatch is resealed after the final flush to prevent airborne dust and insects from entering the tank.

What is different about South Jeddah

South Jeddah is the working end of the city: the Islamic Port, the industrial city with its warehouses and workshops, and behind them older low rise districts such as Ghulail and Al Khumrah. The roads are built for lorries, and port and factory traffic runs through the night, so the dust that settles here is grey with diesel and metal filings rather than pale sand. Buildings are mostly older concrete with flat roofs and open stairwells that collect it. Sea humidity keeps it damp, and in summer it sets hard on ledges and cladding.

Questions worth asking first

Does port traffic directly affect water quality in Al Qawzain?

The port is relatively distant, but general industrial activity may affect air. Tanks need careful maintenance to prevent contaminants entering.

Does the salt content in the air enter the tank directly?

Seawater does not enter directly, but salt and spray deposit on covers and fittings. Cleaning and sterilisation ensure salt does not accumulate.

Does algae grow faster in Al Qawzain than in other districts?

Yes, humidity and heat combined accelerate algae growth noticeably. Coastal tanks need much more frequent cleaning than inland neighbourhoods.

Does high humidity from port proximity speed up algae growth?

Yes, constant humidity is the primary driver of algae. Coastal tanks should be cleaned every two months at minimum.

Do rest houses increase water demand and pollution load?

Rest houses may increase use especially during holidays and occasions. Higher consumption can accelerate sediment accumulation.

Is a new tank cover sufficient to protect water from surrounding pollutants?

A new cover reduces entry but does not prevent it entirely, especially with salt and humidity. Regular cleaning remains essential even with a tight seal.
