Water tank cleaning in Al Manar Jeddah

Al Manar is a mixed district in central Jeddah with villas sharing blocks with modest apartment buildings and neighbourhood shopping centres. It stretches from Hada Al Sham Road north down to Al Samir in the south. Tanks here vary widely: large ones serving apartment buildings alongside small ones in villas and shops. Incomplete drainage networks and damp soil round foundations mean tanks may leak slowly from outside.

Why the job is different in Al Manar

Soil round the house foundations stays damp because drainage is incomplete, and underground tanks may seep slowly from groundwater pressure. The method is set out in full on the full Water tank cleaning page.

The first reason

Incomplete drainage networks leave the soil damp

Al Manar is relatively new and complete drainage networks have not reached all areas yet. Soil round house foundations stays damp most of the year, and underground tanks face groundwater pressure. Slow seepage may let murky water enter the tank from outside as the soil pressure builds.

The second reason

Vacant plots and building work stir up rodents and dust

Open building sites and foundation digging drive rodents from the empty plots toward the homes. Constant dust enters tanks, and insects and rodents search for water and food in the shops and houses nearby.

The third reason

Shops and restaurants feed insects and rodents

The busy commercial spines in Al Manar hold many restaurants and shops. Food waste feeds cockroaches, flies and rodents perfectly. These creatures find their way to nearby tanks and houses to breed.

Before treatment

The condition of the tank decides the method

Al Manar stretches from Hada Al Sham Road in the north down to Al Samir in the south, east of the expressway. Villas share the blocks with modestly priced apartment buildings and neighbourhood shopping centres. The ground is inland and away from the sea, and drainage networks in the newer districts are incomplete.

Fine brown sediment beneath shallow water

The layer on the floor

The floor layer holds sand and clay from damp soil outside, and groundwater may bring fine particles into the tank.

Light and algae

Algae may grow slowly even without direct light, because dampness and organic matter from the soil create a suitable environment.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Tank walls are coated with white and brown sediment from minerals and damp mould.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Cement render may crack from groundwater pressure and ground movement, and cracks let water from damp soil seep in.

The lid of a water tank on a building roof

The lid and the access hatch

Tank lids may not seal tightly and hinges may need lubricating. Openings may lack proper mesh protection.

The vent and the overflow pipe

The overflow pipe may be clogged with mould and damp, and ventilation is weak because excess humidity round the tank.

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 Briman Sub-Municipality

Briman sub-municipality sits east of the Haramain expressway on Jeddah's north eastern edge. Its older quarters are planned grids of villas and walk-up flats, while the outer districts are new subdivisions still being built out. Seasonal wadis such as Wadi Umm Hablain and Wadi Al Asla cross the area, groundwater runs high in places, and drainage networks in the newer districts are incomplete, so soil around foundations stays damp. Vacant plots, live building sites and constant dust give crawling insects and rodents easy routes into homes, and the food outlets along the main arteries keep them supplied.

Questions about this district

Does damp soil seep contaminated water into the tank?

Yes, if the underground tank has fine cracks, groundwater pressure may push dirty water into the tank. Deep cleaning and crack inspection are essential.

Do incomplete drainage networks affect water quality?

Yes, poor drainage means water stays in the soil longer, and high humidity makes bacteria and algae grow faster round the tank.

Digging and building nearby: does it damage the tank?

Yes it can. Vibration may crack the render, dust enters through openings, and rodents migrate toward the water.

Do shops and restaurants next to the house attract insects to the tank?

Yes, food waste attracts cockroaches, flies and ants. These insects may find their way to home tanks searching for water.

Does regular cleaning help if the area has drainage problems?

Yes very much. Regular cleaning and inspection helps catch problems early. We suggest cleaning every two months at least.

Do we need to fix the drainage or just clean the tank?

Tank cleaning is important but fixing the underlying drainage problem is essential in the long run. Both together solve it permanently.

How much does water tank cleaning in Al Manar 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 Manar.
