Why the job is different in Al Naseem

Tanks here are under extreme pressure from very high population density and continuous contamination from restaurants and shops; vast numbers of cockroaches and rodents leave droppings round tank vents. The method is set out in full on how we approach Water tank cleaning.

The first reason

Busy commercial streets supply endless pest populations

Commercial streets packed with restaurants, markets and workshops generate high volumes of waste. This feeds abundant cockroaches and rodents with constant food and shelter, leaving droppings across roofs and around tank openings.

The second reason

Extreme population density stresses water supply and tanks

Very high population density in apartment blocks creates enormous water demand. Tanks fill and drain at extreme rates, pressure swings constantly stir floor sediment and accelerate tank deterioration.

The third reason

Aged pipework delivers rusty water to the tank

The district is among the first areas built beyond the old wall; water networks are very old and heavily rusted. Water arrives brown with iron oxide, and sediment from aged piping compounds tank fouling.

The character of Al Naseem

Mixed district: shops at street level with homes above them

Ground floor shops, restaurants and workshops supply food and shelter to cockroaches, and their droppings enter the tank through ventilation holes and drainage connections throughout the system.

Before treatment

The condition of the tank decides the method

A mixed central zone stretching between King Abdullah Road to the south and Bani Malik Street to the north, with dense apartment blocks, villas and busy commercial streets, near King Abdulaziz University.

Fine brown sediment beneath shallow water

The layer on the floor

The floor layer is brown from rust, sand and droppings, dense and oily from waste, needing strong soaking and repeated hard scraping.

Light and algae

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

A damp concrete wall carrying a dark deposit

The deposit on the wall

Wall deposits are orange from rust and black from cockroach droppings side by side, difficult to remove and needing strong regular scrubbing.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Hairline cracks appear from continuous pressure swings and vibration from dense residential buildings overhead.

The lid of a water tank on a building roof

The lid and the access hatch

The lid and access door are stained with droppings and rust, often difficult to open, and the maintenance hatch inlet is tight and crawling with insects.

A plastic pipe leaving the exterior wall of a building

The vent and the overflow pipe

The vent opening is blocked by cockroach droppings and debris, and the overflow pipe may contain dead insects.

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 Al Sharafiyah Sub-Municipality

The Al Sharafiyah sub municipality runs across central Jeddah from Al Ruwais near the Corniche eastwards through Al Sharafiyah, Al Wurud and Bani Malik to Al Naseem at the Haramain Road. It was among the first areas to grow beyond the old wall, and it is dominated by dense apartment blocks over shops along King Fahd Road and Palestine Street, with old popular quarters, the Bani Malik market, car workshops and storerooms. Ageing buildings, worn drainage and the refuse of restaurants and markets make cockroaches and rodents the most persistent pests, and humidity rises towards the sea.

Questions about this district

Do abundant cockroaches actually enter the tank?

Not usually, but they leave droppings and urine on roofs around the tank. Moisture and spray carry contamination into the water.

Why does water cloud so quickly here?

Aged pipes are rusty, cockroaches leave droppings everywhere, and extreme population density stirs floor sediment constantly.

How often must tanks be cleaned in this type of district?

Every two months minimum. Pests, rust and population stress all contaminate much faster than in quieter areas.

Is a small tank adequate for a large apartment block?

No. Consumption in blocks is extreme; a 5,000 litre tank may fail to serve a 20 flat building.

Does the nearby university affect tank water quality?

It adds traffic but does not directly increase pests in the tank area.

Does cleaning the tank stop cockroaches entering permanently?

No. Cleaning removes what is inside but cockroaches remain on the roof and surrounds. Continuous pest control outside the tank is essential.

How much does water tank cleaning in Al Naseem 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 Naseem.
