Water tank cleaning in Al Fadl Jeddah

Al Fadl is a newly filling residential district in south Jeddah on Old Makkah Road between Al Adl and Prince Fawaz, with apartment buildings, villas and empty plots still under development. Tanks are new but surrounded by warehouses and vegetable and livestock markets, humidity is high and dust is constant, and open stormwater channels beside the tanks carry rainwater and pollutants.

Why the job is different in Al Fadl

Al Fadl tanks are affected by humidity and pollutants from the markets, warehouses and open channels more than other residential neighbourhoods. The method is set out in full on Water tank cleaning in detail.

The first reason

Markets and warehouses with surrounding contamination sources

Al Fadl is ringed by vegetable and livestock markets and warehouses on its edges. Humidity, odours and pollutants from these places enter the tanks, and rodents and insects easily reach the tanks.

The second reason

Large open drainage channels and seasonal flooding

Large open stormwater channels run beside tanks, and after rain they carry polluted water, clay and grit. Small seasonal floods may reach tanks that sit at low level.

The third reason

High humidity and salt from the port and industrial area south

Al Fadl sits close to the Islamic Port and Industrial City, with very humid salt laden air. Tanks face high external moisture pressure and salt accelerates corrosion.

Al Fadl on the map

Al Fadl sits about 2.5 km from North Prince Fawaz and about 3.5 km from South Prince Fawaz.

Before treatment

The condition of the tank decides the method

A rapidly developing area beside warehouses and markets, with open streets and large drainage channels, where tanks face high humidity and contamination from the surrounding commercial activity.

Fine brown sediment beneath shallow water

The layer on the floor

Floor sediment contains clay and grit from drainage channels and markets, deposits fast and sticks firmly.

Light and algae

Algae and fungi grow from high humidity and organic pollutants from markets and warehouses.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Green and brown layers of algae and fungi coat the walls rapidly in high humidity.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Linings may crack from moisture pressure and salt from salty humid air and contaminated water from outside.

The lid of a water tank on a building roof

The lid and the access hatch

Lids and hatches face moisture and pollutants from the markets, and maintenance seals may be weak.

Vent openings may clog from pollutants and dust blown from the markets and open drainage channels.

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

The district has warehouses and vegetable markets. Is the tap water safe to drink from the tank?

Humidity and pollutants from markets and warehouses enter tanks through openings. Regular cleaning and strong disinfection are more important here than in quiet residential areas.

There is an open drain beside the villa and after rain water approaches the tank. Is that dangerous?

Drainage water is very contaminated. If the tank is close to the channel, raise it or build a barrier to protect it from flooding.

The tank is close to vegetable and livestock markets with strong smells. Do they enter the water?

Market smells and particles may enter through poorly sealed vent openings. Replacing or improving vents and adding filters may help.

The villa is new and the tank is new and water turns cloudy after rain. What is the cure?

Floodwater from seasonal flooding may enter through hairline cracks. Inspecting the lining and improving external waterproofing are necessary.

The district is close to the port and the water runs reddish from iron and salt. Where do they come from?

Port salt and humidity speed iron oxidation. Cleaning and disinfection help but tanks need better vent design.

Open drains carry insects and rats. Can they enter the tank?

Insects and rodents can approach the tank. Sealed openings and blocking unnecessary vents are vital here.

How much does water tank cleaning in Al Fadl 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 Fadl.
