Why the job is different in Tarwiyah

Water in Tarwiyah carries moisture from Wadi Mudarraja and fine silt hours after rain, a pattern distinct from districts far from seasonal watercourses. The method is set out in full on what Water tank cleaning involves.

The first reason

Wadi Mudarraja and seasonal moisture

Wadi Mudarraja flows from the north east and carries flash floods after rain, then dries to leave moisture and silt behind. Your tanks sit close to the wadi channel itself, meaning continuous humidity and silt hours after every rain.

The second reason

The Sports City and heavy water use

King Abdulaziz Sports City to the north means heavy water consumption from this zone. Water cycles through faster, sediment builds up quicker, and more frequent cleaning is essential because demand is continuous.

The third reason

New tanks and ongoing building pressure

Most Tarwiyah tanks are very new and construction around them may continue for years. Vibration and dust from sites cause small cracks, so regular inspection matters more than in settled districts.

The character of Tarwiyah

New development: ongoing construction and vacant plots between the homes

New tanks in Tarwiyah face different pressures from continuous moisture and nearby construction. Cleaning must focus on inspection for small cracks and mould under seals, not just sediment removal.

Before treatment

The condition of the tank decides the method

A recent district on a new grid between Al Sharai and Al Rashidiyah south of King Faisal Road, with new villas and apartments and wide vacant plots, Wadi Mudarraja running along the eastern edge.

Fine brown sediment beneath shallow water

The layer on the floor

The moisture and sand layer on the floor builds up from Wadi Mudarraja, requiring full drainage rather than surface cleaning to lift it completely.

Light and algae

Algae grows fast because of continuous moisture from the wadi, especially after seasonal rain. Cleaning intervals shorter than three months work better here.

A damp concrete wall carrying a dark deposit

The deposit on the wall

The wall layer is fine sand mixed with mould from persistent moisture, and pressure washing clears it, but mould returns because humidity stays high.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Hairline cracks may appear from building vibrations nearby and constant moisture stress. Regular inspection for small cracks matters after construction activity and the first rain.

The lid of a water tank on a building roof

The lid and the access hatch

Covers and hatches need strong sealing against moisture. Old seals need regular replacement to stop moisture and insects entering from damp ground nearby.

A plastic pipe leaving the exterior wall of a building

The vent and the overflow pipe

Ventilation openings and overflow pipes can worsen moisture and sand ingress from Wadi Mudarraja. A strong filter on the vent is necessary, and the overflow may need separate cleaning.

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 Sharai Sub-Municipality

Al Sharai is the eastern growth front of Makkah along King Faisal Road and the Taif road. Settled quarters sit beside recently renamed schemes where plots are still vacant and buildings are going up, so construction sites, fill and open excavations lie next to occupied homes. Wadi channels such as Wadi Mudarraja, Wadi Al Sharai and Wadi Al Mughammas carry flash floods after rain and dry out to damp silt, while dust blows off the open hills. Roadside shops, restaurants and warehouses line the Taif road, and to the east the area shades into villages, palm farms and springs.

Questions about this district

New house water goes cloudy hours after rain here, does it come from the wadi?

Wadi Mudarraja nearby sends moisture and silt when rain falls. Water may run cloudy for days, and cleaning after heavy rain is wiser than waiting for it to clear.

Humidity around the new tank is very high even on dry days?

Wadi Mudarraja dries slowly and leaves high moisture in the soil. Good ventilation around the tank matters, and cleaning must include checking for mould under the cover.

Green algae grows fast despite regular cleaning in Tarwiyah?

Moisture from the nearby wadi encourages rapid algae growth. Two monthly cleaning beats three monthly intervals, especially after seasonal rain.

Does building activity around the new tank weaken it or is it strong enough?

New tanks are strong, but vibration from nearby construction may cause small cracks around corners. Inspection after major digging and the first rain is safer than assuming strength alone.

New tank water is slightly yellow from copper pipes or iron in the metal?

Fresh Tarwiyah pipework releases iron and copper particles at first. The yellow tint fades with time, and draining the first water from taps helps reduce it.

Water holds fine sand weeks after tank cleaning was completed recently?

Wadi Mudarraja sends fine sand with moisture that may return from the soil. Sand may also blow in from the air. Extra filters are necessary in Tarwiyah.

How much does water tank cleaning in Tarwiyah 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 Tarwiyah.
