Water tank cleaning in Al Basatin Jeddah

Al Basatin is a villa district north of Jeddah between Al Murjan and the shoreline, where high sea humidity and salt laden air dominate. Tanks here corrode rapidly from inside because moisture remains high throughout the year, and large irrigated gardens keep the soil around pipework continuously wet. Tank cleaning must also include checking pipes for leaks and corrosion deposits that the irrigation cycle accelerates.

Why the job is different in Al Basatin

Tanks in Al Basatin are wide and shallow because large villas need bulk storage, and moisture means the tank floor sits on wet sand around the house foundation, allowing water and contamination to seep upward. The method is set out in full on how we approach Water tank cleaning.

The first reason

Rapid internal corrosion from sea humidity and salt air

The high humidity and salt in shoreline air accelerates cement tank wall corrosion from within. This corrosion leaves cement dust and sand settling in the tank bottom faster than in inland districts. Cleaning must be deeper and drainage more thorough.

The second reason

Pipe leaks from constant moisture and pressure load

Continuous garden irrigation keeps soil around house pipes permanently wet, causing leaks in old or even new pipes if they lack complete water proofing. Leaked water mixes with irrigation water and returns to the tank carrying soil and contaminants.

The third reason

Insects and mosquitoes breeding in irrigated gardens around the villa

Large gardens and irrigated green spaces around villas create perfect mosquito and ant habitat. These insects enter the tank through ventilation openings or small cracks, and tank cleaning alone will not solve this without treating the gardens and damp areas around the house.

Landmarks of Al Basatin

Tanks in Al Basatin are reached usually via villa rooftops adjacent to King Abdulaziz Road or Al Basatin Street, where wide gardens and green spaces make access easier than in densely built quarters.

Before treatment

The condition of the tank decides the method

Al Basatin stretches along the northern coast between Al Murjan and Madinah Road, with large villas set on generous plots and continuously irrigated gardens, where sea humidity means timber, concrete and metal stay damp most of the year.

Fine brown sediment beneath shallow water

The layer on the floor

Floor sediment in Al Basatin tanks includes fine sand and cement dust bonded by moisture, needing high pressure washing with care not to weaken old tank walls.

Light and algae

Light and algae may grow in tanks exposed to sun on villa roofs, but algae here may be green rather than black because it needs more light than tanks in dense housing.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Walls stay damp because of external humidity, and deposits may be green or black depending on how much light reaches inside the tank.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Linings may crack from moisture and the continuous expansion and contraction caused by seasonal temperature and humidity swings.

Lids and hatches in new villas seal well, but water seeping up around the base may enter through lower ventilation openings.

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 Obhur Sub-Municipality

Obhur sub-municipality runs along Jeddah's northern shoreline from Al Shati up to Obhur Creek. It mixes large villas and gated compounds with busy commercial spines of restaurants, cafes, markets and hotels. Sea humidity is high for most of the year and salt laden breezes keep timber and render damp, while irrigated gardens and lawns surround the corniche and the villa plots. Standing irrigation water, dense planting and food waste from the hospitality strip suit cockroaches, mosquitoes and ants, and the chalets and rest houses scattered along the creek stand empty for long spells, which lets insects and rodents settle undisturbed.

Questions about this district

Water in our new villa is white and very cloudy from the first day we moved in, why?

New villas often have tanks that were not cleaned before filling from the network. New water drags building dust and cement debris from inside the tank and pipes. Comprehensive cleaning in the first week of occupancy solves this entirely.

Does garden moisture really affect water quality in the tank?

Yes, very much. High moisture around pipes causes leaks, and leaked water mixes with irrigation water and garden soil before returning to the tank. If pipes lack proper waterproofing, repeated cleaning will become necessary.

We keep finding mosquitoes and insects around the rooftop tank, why is this?

The irrigated gardens and lawns around the villa provide ideal mosquito and insect breeding habitat. Ventilation openings on the tank may be their entry point. Sealing openings with fine mesh and reducing moisture around the tank is essential.

Should we replace the pipes instead of repeated cleaning here?

If pipes are old and lack water proofing, and leaks are frequent, replacing or re-waterproofing them may be cheaper long term than monthly cleaning cycles.

Hot water quality is worse than cold water from the same tank, why?

Warm water accelerates bacterial growth in the tank, especially if there are deposits or old lining. Deep cleaning and disinfection, plus heater inspection may be needed.

How often should a tank in Al Basatin be cleaned?

Given the high humidity, irrigated gardens and seafront location, every three months is recommended. In summer, more frequent cleaning may be needed if there are insect eggs or water leaks.

How much does water tank cleaning in Al Basatin 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 Basatin.
