Why the job is different in Al Nuzhah

Old piping carries water brown with rust and iron oxides; the first water from a tap is often orange red, a sign the pipes are heavily corroded inside. The method is set out in full on how we approach Water tank cleaning.

The first reason

Aged pipes coat the incoming water with rust

Water and drainage networks are three decades old or more, their insides caked with thick rust layers. Fresh water dissolves iron particles as it flows, arriving at the tank already brown with oxidised iron.

The second reason

Abundant restaurants attract dense pest populations

Commercial streets overflow with restaurants and food shops generating high volumes of waste. This feeds large populations of rodents and cockroaches hunting shelter and food.

The third reason

Furnished flats and high turnover stress the water system

Furnished apartments on commercial streets host tourists and guests at high rates, so water consumption is extreme. The tank fills and empties rapidly, stirring floor sediment constantly and accelerating rust extraction.

Landmarks of Al Nuzhah

Tanks on Sultan bin Salman Street and near Mall of Arabia draw water from pipes that are decades old, and closeness to the Sixtieth junction and congested commercial streets multiplies restaurants and food vendors that shelter high numbers of insects and rodents.

Before treatment

The condition of the tank decides the method

An older district built decades ago between Madinah Road and King Fahd Road, with busy commercial streets like Quraish, Sari and Sultan bin Salman lined with restaurants, furnished flats and popular markets.

Fine brown sediment beneath shallow water

The layer on the floor

The floor layer is thick brown iron oxide and rust, hard and consolidated, needing long soaking and strong scraping to remove.

Light and algae

Green algae is sparse because iron oxide kills most algae, but iron bacteria thrive in the sediment layer.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Wall deposits are orange rust, bonding hard to concrete or metal, needing mild acid treatment before scraping.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Hairline cracks are uncommon but minor ruptures occur when rust expands internally and spalls the walls.

The lid of a water tank on a building roof

The lid and the access hatch

The lid is rusted outside, and the maintenance hatch may be tight and difficult to open.

A plastic pipe leaving the exterior wall of a building

The vent and the overflow pipe

The vent opening may clog with rust particles, and the overflow pipe may corrode from inside.

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 Airport Sub-Municipality

The Airport sub-municipality covers some of the oldest established districts of northern Jeddah, gathered around King Abdulaziz International Airport between Madinah Road, King Fahd Road and Prince Majid Road. The stock is villas, single family houses and apartment blocks built decades ago, many served by ageing water and sewer lines. Commercial streets such as Quraish, Sari and Sultan bin Salman are lined with restaurants, furnished flats and popular markets. Dense commercial kitchens, worn pipework and the gaps in older buildings give cockroaches and rodents steady food and shelter, and the high resident population keeps that pressure constant through the year.

Questions about this district

Why does water from the tap come out orange red?

Old piping is heavily rusted inside; stagnant water dissolves rust. The first water out is iron-rich. It clears after minutes but the sediment remains in the tank.

Is excess iron in the water dangerous?

High iron may cause constipation and affect children. The moisture from dissolved iron can reduce calcium absorption.

How often should tanks be cleaned in old districts like this?

Every two months minimum. Rust and sediment accumulate quickly, and high consumption stirs deposits constantly.

Would replacing all the pipes stop the rust problem?

Yes, but replacing an entire water network is very costly. Tank-side filters help a little but cannot solve the core problem.

Do cockroaches from nearby restaurants get into the tank?

Cockroaches leave droppings around tank openings and may enter during cleaning or when the lid is opened. Most contamination is faecal matter outside the tank seeping in.

Does Mall of Arabia and the busy junction near the tank cause extra problems?

Both multiply restaurants and food vendors nearby, raising insect and rodent populations and stirring more dust across the district.

How much does water tank cleaning in Al Nuzhah 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 Nuzhah.
