Why the job is different in Al Wazeeriyah

Tanks here carry mixed sediment from both domestic and commercial use, with irregular pumping patterns because consumption swings between day and night and between shop hours and residential hours. The method is set out in full on Water tank cleaning in detail.

The first reason

Mixed consumption and uneven sediment distribution

In Al Wazeeriyah a single tank may feed both a villa or flat and the commercial shop directly below it. The shop draws water heavily during business hours morning and evening, while the flat draws it differently. This irregular consumption produces uneven settlement of sediment at the tank bottom, with heavier layers where pressure is lowest.

The second reason

Contamination from commercial and residential activity together

Tanks in mixed districts face both food service pollution and residential use at once. Cleaning water from the shop can enter the tank through old pipes, and bacteria from food handling mixes with natural sediment. The tank essentially becomes a filter between two incompatible uses, and neither thrives without regular cleaning.

The third reason

Constant pressure on the tank from intensive use

The district is close to Prince Abdullah Al Faisal Stadium and King Abdulaziz Hospital, water demand spikes at certain hours. The tank endures rapid filling and draining cycles repeated many times each day, accelerating lining corrosion and hairline cracks, and making seepage more likely to occur.

The character of Al Wazeeriyah

Mixed district: shops at street level with homes above them

A mixed district means your tank faces irregular consumption and contamination from multiple sources. The shop below may draw large amounts of polluted water while flats around you depend on clean water. Regular tank cleaning and clean pipes protect everyone from degraded water quality.

Before treatment

The condition of the tank decides the method

Al Wazeeriyah is a small compact residential district of south Jeddah, framed by Stadium Street, Al Falah Road and Al Mahjar Street, mixing apartment blocks and villas with dense shops and restaurants at street level.

Fine brown sediment beneath shallow water

The layer on the floor

The settled layer at the bottom of mixed use tanks is a mixture of food residues, minerals and salts, unevenly distributed because consumption is intermittent.

Light and algae

Algae grows in tanks exposed to light through broken hatches and may be green or brown depending on the type of contaminants present.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Wall deposits may be thick from mineral and salt precipitation, especially near openings where water evaporation is fast.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Linings in intensively used tanks corrode faster from constant pressure swings, rapid filling and draining cycles, and moisture that never fully dries.

The lid of a water tank on a building roof

The lid and the access hatch

Covers are often loose because heavy use means opening the tank more often than residential use demands, and the hinges may already be bent.

A plastic pipe leaving the exterior wall of a building

The vent and the overflow pipe

Vent openings and overflow pipes may be blocked by dust and salt, and may discharge water into the street during rapid filling in peak demand hours.

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 South Sub-Municipality

The South sub municipality runs from the edge of Old Makkah Road down to Al Khumrah and the southern corniche. Dense residential districts sit beside new subdivisions such as Al Sanabil and Al Taawun, warehouse fringes such as Al Saruriyah and Al Sarawat, and an old seaside settlement at Al Quzayn. Open stormwater channels cross the housing, and the warehouses, the vegetable and livestock markets and the nearby Islamic Port and Industrial City give pests shelter, food and year round humidity. Pressure is greatest in the older quarters, where drainage networks are ageing.

Questions about this district

My flat is above a shop sharing one tank. Does it harm the flat?

It can. If the shop uses large amounts of polluted water, flat residents experience poor water quality. Regular tank and pipe cleaning prevents this, and in some cases separate piping becomes necessary to protect residential use.

The bathroom tap runs cloudy when cleaning is happening in the shop below. Connected?

Yes. When the shop drains the tank fast, sediment from the bottom stirs up and enters the distribution pipes. Slow pumping after cleaning prevents this, and in some cases you may need a filter in the rising pipes.

There is a small hotel in the district. Is its tank different from residential tanks?

Very different. Even small hotels need far more frequent cleaning because use is intensive and guests turn over. Bacteria from bathrooms and kitchens accumulate much faster than in residential use.

The water pressure from the tank is weak. Could sediment be blocking it?

Possibly. Sediment in the rising pipes from the tank reduces pressure. Cleaning the tank and flushing the pipes may help, but if the pump itself is weak, cleaning alone may not restore strong flow.

Must the shop close during tank cleaning?

Preferably yes. When we drain the tank, neither the shop nor the flats have water for several hours. The best time is shop closing and the early morning hours before residents wake.

The tank is very old and has not been cleaned in years. How long does it take?

Many hours if sediment is very thick. We may need slow drainage and hand scrubbing with brushes before high pressure washing. A neglected old tank may need cleaning in stages over more than one visit.

How much does water tank cleaning in Al Wazeeriyah 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 Wazeeriyah.
