Why the job is different in Al Safrah

Tanks here are very far apart and water sits for long periods in long pipes. The soil is damp and the water table is high, so water may seep into the tank from below. The method is set out in full on how we approach Water tank cleaning.

The first reason

Nearby wadis, flooding and standing water

Wadis nearby carry water in winter and flooding may reach near tanks. Stagnant water in wadis causes high humidity and many insects around the tank.

The second reason

High water table and seepage from below

Soil here is damp and ground water sits close to the surface. Water may leak from the tank bottom in wet seasons or polluted water may seep into the tank from the earth.

The third reason

Long pipes and stagnant water growing anaerobic bacteria

Tanks are far apart so pipes are very long. Water sits in pipes for extended periods and anaerobic bacteria grow, producing strange smells and gases.

The character of Al Safrah

Rural area: farms, open ground and scattered homes

Rural areas mean isolated tanks and stagnant water and pollution from nature not people. Ground water, wadis, insects and rodents are the main threats, not human consumption.

Before treatment

The condition of the tank decides the method

A small rural area on the city edge with farms and open ground and very scattered houses, nearby wadis and damp soil, high water table.

Fine brown sediment beneath shallow water

The layer on the floor

The floor layer is brown and mixed, drawing from ground water and wadi silt. Removal is hard because sediment clings and water tends to sit.

Light and algae

Black algae and fungi grow fast from continuous damp and standing water. Low light favours fungal growth.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Wall coating is thick and mixed with organic sediment and fungal film. Cleaning needs special technique to clear odours.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Lining may crack from pressure caused by ground water rising below. Cracks allow dirty water from earth to seep in.

The lid of a water tank on a building roof

The lid and the access hatch

Lids and openings may lack tight protection in rural areas. Insects and rodents from wadis enter easily.

A plastic pipe leaving the exterior wall of a building

The vent and the overflow pipe

Air vents and overflow pipe may clog with dust and insects from wadis and open land.

How we work

1
Inspect before the drain

Tank type and material, the condition of the lining, the depth of the sediment, the lid and the vent, and where the drained water will go. We agree the window without supply before anything is opened.
2
Drain, then lift the sludge

The water leaves through the outlet, then the layer beneath it is taken out by hand and by suction. That layer is the reason for the visit, not the water that ran out ahead of it.
3
High pressure wash

Walls, floor and the joint where they meet, with a brush wherever the film resists, then the wash water is taken out completely so nothing we lifted settles again.
4
Disinfect and put back in service

Disinfectant over every internal surface, left for its contact time and then rinsed out, followed by the refill, a first draw off at the taps, and a report on what was inside the tank.

What water tank cleaning includes

An inspection before the valve

Tank type, lining condition, depth of sediment, lid and vent, recorded before any water leaves.
Full drain and sediment removal

The water through the outlet, and the layer below it by hand and by suction until the floor itself is showing.
Pressure washing walls and floor

High pressure across the surfaces and corners, and a brush on anything water alone will not lift.
Disinfection after the wash

A disinfectant intended for drinking water tanks, named to you before it is used, left for its contact time and then rinsed out.
Refill and the first draw off

We refill, run the taps so the new water moves through the pipework, and tell you when it is ready to use.
A report and the next date

What was inside the tank, anything on the lid or the lining that needs repair, and a sensible date for the next clean.

What is different about Al Aziziyah (Makkah) Sub-Municipality

Al Aziziyah sub municipality runs from the Bin Dawood markets to the Al Hada road and carries pilgrim traffic to Mina. Hotel towers and furnished apartment blocks fill and empty with the Hajj and Ramadan seasons, and the kitchens, restaurants and markets along Al Masjid Al Haram Road and King Abdulaziz Road leave food waste at every peak. Southwards the fabric loosens into villas and planned streets in An Naseem and Al Awali, then Al Abidiyah's campus and the old farms of Al Husayniyah, where Wadi Uranah holds water after rain and farm enclosures shelter rodents and reptiles.

Questions about this district

Is water leaking from below the tank a sign that the water table has risen?

Yes. In winter and heavy rains the water table rises and may seep into the tank from below or cause leaks.

Does the strange smell from a rural tank come from old water sitting in long pipes?

Yes. Long pipes hold old water for extended periods. Anaerobic bacteria grow and produce foul smell.

Do insects from nearby wadis enter the tank more easily than in crowded quarters?

Yes. A remote rural tank may lack tight protection. Insects from wadis and open land enter easily.

Will cleaning the tank fix the problem of leaks from below in damp soil?

Cleaning removes bacteria and sediment. Leaks from below need external tank sealing or ground water management.

Do wadis affect tank water quality directly or only through the water table?

Wadis mainly act through raising the water table during flooding. They may affect directly if very close to the tank.

How often must a rural tank be cleaned?

A rural tank needs cleaning at least every three months because water sits long and pollution from ground water and wadis is continuous.

How much does water tank cleaning in Al Safrah cost?

It is set after the inspection, because the price follows the type of infestation, the size of the space, how far it has spread and the number of visits it needs. Send a photo and a description on WhatsApp and we will give you an estimate before we reach Al Safrah.
