Why the job is different in Al Sawari

Commercial tanks foul faster than residential ones because usage is more intense and cooking and laundry leave grease and suspended matter that settles more quickly than household sediment. The method is set out in full on how we approach Water tank cleaning.

The first reason

Mixed use accelerates sediment layering

In a mixed district, a single tank may combine residential and commercial use: restaurants, cafes and pharmacies consume more water and leave suspended matter that settles and hardens faster, shortening the safe interval between cleans compared to a housing only block.

The second reason

New plumbing runs beside aging pipework

Al Sawari contains recently built blocks alongside older buildings. New pipework is clean, but older pipes shed rust and scale that travel to the tank and accelerate sediment buildup, requiring deeper sediment removal than in newer areas.

The third reason

Sea humidity affects exposed tanks on roofs

The district's coastal setting means exposed rooftop tanks face high humidity and salt drift, which accelerates lining deterioration and speeds algal growth on internal walls. Coastal tanks need more frequent algae inspection than inland ones.

The character of Al Sawari

Mixed district: shops at street level with homes above them

In a mixed district, one tank may serve occupants with entirely different consumption patterns, so cleaning strategy must be flexible enough to handle the high intensity of commercial use while ensuring stable clean water for residential needs.

Before treatment

The condition of the tank decides the method

The district lies between King Saud Road and Prince Abdulmajeed Road on recently developed coastal ground with moderate humidity and sandy subsoil from the shore's proximity.

Fine brown sediment beneath shallow water

The layer on the floor

Floor sediment in Al Sawari tanks collects construction dust and fine sand from the coastal building site and needs powerful suction to remove it completely during the initial drainage phase.

Light and algae

Light reaches exposed rooftop tanks and green algae grow fast, especially during warm seasons when water sits still. The coastal location and summer sun make algal growth faster here than in inland districts.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Walls accumulate white scale from calcium and magnesium salts, and the layer is thicker in tanks where continuous evaporation concentrates minerals from standing water.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Plastic linings in newer tanks can develop hairline cracks from building vibration and sharp temperature swings that the coast's humid, sunny climate amplifies.

The lid of a water tank on a building roof

The lid and the access hatch

Tank lids and access hatches in mixed use areas suffer repeated opening and closing, wearing seals and hinges faster than in residential only blocks where usage is more stable.

The vent and the overflow pipe

Vent holes and overflow pipes become entry points for insects and dust, especially on humid coastal nights, so they need fine mesh guards that are checked and cleaned during every service.

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 Dhahban Sub-Municipality

Dhahban sub municipality is the northern coastal strip of Jeddah, running from the north bank of Sharm Obhur up to the old village of Dhahban and Salman Bay. Its districts are recently built, with owner occupied villas and apartments, beach resorts and chalets on the shore, and land subdivisions still being developed. Nearness to the sea keeps humidity high all year, irrigated lawns in villas, resorts and district parks hold water, Wadi Obhur and the vacant plots between buildings give rodents and reptiles shelter, and the old fishing village of Dhahban gives the far north a rural edge.

Questions about this district

Do commercial tanks in shops need cleaning more often than flats?

Yes, commercial use is more intense at set times and leaves grease and suspended matter that settles faster. A restaurant tank may need cleaning monthly while a residential flat could wait three months.

Why does water turn cloudy faster in summer in our area?

Heat speeds algal growth on tank walls and increases bacterial activity. Lower water density raises settled matter, and evaporation concentrates minerals, all of which cloud the water and speed up the visible fouling cycle.

Do you clean rooftop and underground tanks by the same method?

No, rooftop tanks are exposed to light, heat and dust, so they need different treatment. Underground tanks are cooler and darker but prone to moisture and seepage from surrounding soil and well walls.

If the tank is new, does it need cleaning in the first year?

Yes, even new tanks collect manufacturing dust, scale from welding and metal particles from transit. A first clean removes these contaminants before they build up and affect water taste and clarity.

What should we do if the water smells odd coming from the tap?

It could be sulphur from fermented sediment or anaerobic bacteria at the tank floor. Full cleaning and disinfection removes it, though the smell may return if the pipework is old and corroded.

Can we use the water immediately after cleaning or should we wait?

After the final rinse and disinfection, wait a few hours for the disinfectant to work. For drinking water, wait until chlorine vapour has gone. Overnight storage after cleaning is good practice for mixed use blocks.

How much does water tank cleaning in Al Sawari 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 Sawari.
