Water tank cleaning in Al Wahah Jeddah

Al Wahah is a relatively newly built villa district extending east of Haramain Road and north of Palestine Road, laid out to a regular plan with villas, apartment buildings and commercial strips. Subdivisions under construction and active excavation around the district mean tanks receive dust from building sites, and incoming water may carry fine sand from the new supply network.

Potable-rated materials

Linings and disinfectants cleared for drinking water tanks, not general-purpose products.
You get the downtime first

How many hours the tank is out of service, told before we start rather than after we finish.
A first-draw flush

We run the first draw off after refilling, and the tank is not handed back until the water runs clear.

Villas, apartment blocks and premises that need a written record of each visit.

Why the job is different in Al Wahah

Tanks here receive water from a relatively new network, but active building sites nearby release dust that may enter the tank through ventilation openings. The method is set out in full on Water tank cleaning in detail.

The first reason

Subdivisions under construction around the district provide a continuous dust source

Land surrounding Al Wahah still sees active construction, and excavations and building work release fine dust. Tanks may receive building dust through vent openings and damaged lid seals.

The second reason

A relatively young water network may still carry commissioning residue

The network in a new district like Al Wahah may still contain sediment from initial system flushing. New pipes may not have settled yet and may release trace metals.

The third reason

The growing new district and surroundings create increasing network pressure

Al Wahah is expanding fast and adjacent districts like Al Nakhil and Al Rehab are growing too. Pressure on the network may increase as the population grows, causing water pressure fluctuations.

The character of Al Wahah

Villa district: private plots, gardens and a boundary wall to every house

A relatively newly built villa district surrounded by subdivisions under construction means tanks face a temporary burden from dust and an emerging network. The problem is not permanent but may take years to fully resolve as the district grows and the water network stabilises.

Before treatment

The condition of the tank decides the method

A relatively newly established villa district extending east of Haramain Road and north of Palestine Road, with planned layout including villas, apartment buildings and commercial streets, with Al Wahah Park, neighbourhood mosques and private schools, adjoining Al Nakhil and Al Rehab.

Fine brown sediment beneath shallow water

The layer on the floor

Sediment from surrounding construction dust is fine sand and clay, settling fast but easily resuspended by flow changes.

Light and algae

Algae is rare now because of stable usage and a new environment, but may grow if chlorine levels drop.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Wall deposits contain fine sand and traces from the new network, and washing reveals sediment stuck to the surfaces.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Hairline cracks in relatively new tanks are still small but widen with use and pressure changes.

The lid and the access hatch

Lid seals may be in good condition but wear from pressure changes as the population grows.

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 Umm Al Salam Sub-Municipality

The Umm Al Salam sub municipality covers the east and south east of Jeddah along the Old Makkah Road and the Haramain Road. It pairs recently planned districts such as Al Wahah, Al Nakhil and Al Shuruq with popular districts that grew outside formal planning, including Al Harazat, Al Mahamid and Umm Al Salam. The older areas have ageing drainage, unpaved streets and vacant plots where building waste collects, conditions that suit rodents, cockroaches and ants. The newer areas are ringed by half built subdivisions and open excavations.

Questions about this district

Does dust from construction sites adjacent to the district enter tanks?

Yes, especially on humid days or after rain when dust is heavy. Loose openings allow fine dust to enter the tank.

Why is water cloudy again shortly after cleaning?

The new network may still contain residue from initial commissioning work. Fine sand from building sites may enter the tank.

Will these problems disappear when construction around the district ends?

Yes, when new subdivisions finish building and the network settles, problems will decrease. But it may take years for the environment to fully stabilise.

Should we add filters to the incoming water line?

Yes, it can help. A simple filter may reduce dust and fine sand entry. The filter needs regular cleaning.

Does water pressure drop at peak usage times?

Yes. The new district is expanding fast and the network may fall short during peak usage periods.

Do we need more frequent cleaning than in established districts?

Yes. You may need cleaning every six months until the surrounding districts and network fully settle.

How much does water tank cleaning in Al Wahah 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 Wahah.
