Why the job is different in Al Rehab

Tanks in Al Rehab accumulate sediment faster than purely residential areas because water moves through the system continuously and consumption is irregular across different user types. The method is set out in full on Water tank cleaning in detail.

The first reason

Mixed use changes water circulation patterns

Shops, offices and the university consume water differently from family homes. Tanks suffer uneven pressure swings and interrupted flow, causing sediment to settle faster and debris to gather heavily on the floor in some spots more than others.

The second reason

King Abdullah Road vibration and dust

The main highway runs through the district, and vehicle vibration unsettles tank stability while road dust and emissions increase humidity and contamination around lids. Water entering through overflow pipes carries external pollutants inward.

The third reason

Dense building crowds shared tank systems

The district packs villas, apartment blocks and residential units closely together. Shared tanks serving multiple buildings face heavier loads and unequal drainage, so sediment collects unevenly on the floor in pockets rather than in uniform layers.

The character of Al Rehab

Mixed district: shops at street level with homes above them

Shops and offices below flats mean the tank supplies drinking and cooking water upstairs but also serves less demanding uses below. Mixed water quality demands precise cleaning and more frequent turnover to keep standards high.

Before treatment

The condition of the tank decides the method

Al Rehab lies between Al Arbaeen Street and the expressway, where residential, commercial and academic use creates varied demand on tank capacity and water flow patterns.

Fine brown sediment beneath shallow water

The layer on the floor

Floor sediment in Al Rehab is white and grey from expressway dust and renewed building work, and gathers faster than in other districts because of constant vehicle vibration and construction activity nearby.

Light and algae

Algae is rare in Al Rehab tanks because they are well covered and far from direct light, but cracks in lids may allow light to reach corners where algae can grow silently between cleanings.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Wall deposits are thick and mixed in colour because water use varies so much across the district. Hot water from heaters leaves more mineral film than cold water, forming a stubborn brown layer.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Plastic linings in Al Rehab suffer hairline cracks from vibration and heat stress from dense building, so inspecting the lining during cleaning is essential and saves much bigger repairs later.

The lid and the access hatch

Tank lids and access hatches rust fast in Al Rehab because humidity rises from mixed commercial and residential activity and constant building work. Hinges need regular greasing to stay operable.

The vent and the overflow pipe

Ventilation holes clog quickly with road dust from the expressway, and overflow pipes need regular cleaning because water spilled there may attract insects or develop algae growth in warm months.

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.

Landmarks of Al Rehab

Al Rehab tanks lie between Al Arbaeen Street and King Abdullah Road, which cross the district from opposite edges. Work is coordinated near University of Jeddah's Al Rehab campus, which helps identify peak traffic times and the best windows for tank access and maintenance.

Questions about this district

Does a shared tank between flats above and a shop below need different cleaning?

Yes. The shop uses more water and in bursts, so a shared tank faces constant pressure swings and sediment gathers in different corners. Cleaning must be deeper and more thorough than in purely residential buildings.

Does constant vibration from King Abdullah Road harm tank integrity?

Ongoing vibration from heavy traffic can cause small hairline cracks in the lining. Inspection during cleaning catches these before they become serious leaks that demand expensive repairs.

Does water in Al Rehab carry more dust than other districts?

King Abdullah Road brings constant dust, exhaust and humidity. Tanks receive this pollution through ventilation holes and overflow pipes, so more frequent cleaning keeps the water clear.

How often should a tank in a dense mixed district like Al Rehab be cleaned?

Mixed and interrupted use causes sediment to pile up faster. Every three to four months is better than the six month intervals you would use for purely residential areas.

Does University of Jeddah and the markets affect tank water quality?

High activity and ongoing building work raise dust and humidity around tanks. Hot water from cafeterias and restaurants may carry more kitchen debris and soap residue into the system.

Is water from a tank shared between shops and flats less clean than purely residential?

Shops bring cooking odours, kitchen waste and cleaning chemicals. Flats use cleaner water. The mix weakens overall tank water quality and demands more precise and frequent cleaning attention.

How much does water tank cleaning in Al Rehab 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 Rehab.
