Water tank cleaning and sterilising in Al Qaws, Jeddah

Al Qaws is an eastern district situated on the course of Wadi Al Qaws, which was the main source of Jeddah's notable 2009 flood.

Why a clean tank matters for your water supply

The district lies on the course of Wadi Al Qaws in east Jeddah near Mareekh Mountains, within a region of hills and valleys away from the coast.

Seasonal maintenance before peak use

Al Qaws accumulates heavy clay sediment from the wadi especially; cleaning focuses on deep removal of clay from the tank floor.
After a long property vacancy

After a seasonal closure, the tank may remain exposed to moisture and clay seepage from the wadi that runs beside the district.
Visible discolouration or unusual taste

Seasonal absence may leave the tank unchecked for long periods, so inspection before reoccupancy is wise, especially after the rainy season.
Landlord or building inspection requirements

Before Ramadan and the entertaining season, tank cleaning removes heavy clay and ensures safe water free from unusual taste and smell.

What changes about water tank cleaning and sterilising in Al Qaws

Tanks in Al Qaws need specialised cleaning to remove heavy clay sediment that deposits rapidly from wadi water. For the whole method, see the full water tank cleaning and sterilising page.

The first reason
Wadi Al Qaws carries heavy clay during seasonal rains

The wadi that gave the district its name was the source of the famous flood. Moisture and clay enter tanks through roof seepage and foundation cracks during rainfall.
The second reason
Nearby hills and mountains raise fine dust clouds

The Mareekh Mountains raise fine dust during strong wind. Fine particles enter tanks through vents and loose covers.
The third reason
Relatively old district with aged roofs and covers

Al Qaws is among the older neighbourhoods in east Jeddah, with older roofs and covers that are less tightly sealed. Water and dust enter easily.

The character of Al Qaws

Mixed district: shops at street level with homes above them

In a district on a historic wadi course, the tank faces unique challenges from clay sediment and potential flooding. Regular inspection and preventive maintenance are essential, especially before the rainy season.

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.

Questions worth asking first

Does Wadi Al Qaws flood the tanks during heavy rain?

In severe rainfall, wadi water may seep into tanks from below. Regular inspection and testing catch early seepage.

Does wadi clay affect the taste of the water?

Yes, heavy clay settles on the tank bottom and leaves a strange taste and grey colour. Full cleaning removes accumulated clay.

When should the tank be cleaned after the rainy season?

Right after rains end, the tank should be inspected. If clay sediment is present, urgent cleaning is necessary.

Do the nearby Mareekh Mountains affect water quality?

Mountains raise fine dust in the wind, especially in spring and autumn. This dust enters the tank through vents.

Do old roofs in this district cause water leaks into the tank?

Yes, old roofs and covers may leak water directly into the tank. Maintenance and repair are necessary.

Does regular cleaning reduce the risk of wadi flooding the tank?

Regular cleaning does not prevent flooding, but it removes accumulated sediment and allows fresh water to flow more easily after rains end.
