Water tank cleaning in Khadra, Makkah

Potable-rated materials

Linings and disinfectants cleared for drinking water tanks, not general-purpose products.
You get the downtime first

How many hours the tank is out of service, told before we start rather than after we finish.
A first-draw flush

We run the first draw off after refilling, and the tank is not handed back until the water runs clear.

Why the job is different in Khadra

Tanks fill with building dust faster than in settled districts, and the settled layer at the bottom becomes a mixture of clay and fine sand rather than uniform sediment. The method is set out in full on what Water tank cleaning involves.

The first reason

Construction materials entering from open excavations

Open excavations around new homes and buildings under construction release dust, fine sand and construction debris that enters tanks through ventilation openings and damaged lid seals. Building materials easily pass through simple filters and accumulate rapidly on the tank floor.

The second reason

New hairline cracks in newly installed tanks

Tanks installed recently in new buildings have not yet gone through complete thermal cycles and their hairline cracks are still small but widening over time. Adjacent construction and vibrations from heavy vehicles accelerate this wear.

The third reason

Absence of stable infrastructure and municipal services

The district is still in its construction phase, streets are under development and drainage is irregular. Tanks depend on temporary water flows and may receive unstable water composition until full municipal infrastructure is in place.

Before treatment

The condition of the tank decides the method

The district sits east of Al Sharai on King Faisal Road as a series of new residential schemes and apartment blocks under continuous construction, with excavations and site work happening between homes.

Fine brown sediment beneath shallow water

The layer on the floor

The floor layer here is a mixture of clay and fine sand from new building sites, settling faster and more densely than in older districts.

Light and algae

Sunlight reaches settled tanks easily in the open spaces between new buildings, speeding algae growth in exposed tanks that lack shade.

A damp concrete wall carrying a dark deposit

The deposit on the wall

The wall deposit here contains fine sand stuck fast rather than soft lime scale, requiring longer pressure washing to remove completely.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Hairline cracks in newly installed tanks are small but permit entry of fine pollutants from a dust laden environment full of ongoing building activity.

The lid of a water tank on a building roof

The lid and the access hatch

Seals on newly fitted tank lids may be loose after installation because vibrations from adjacent heavy construction loosen them over time.

A plastic pipe leaving the exterior wall of a building

The vent and the overflow pipe

Ventilation openings need frequent inspection because fine dust from building sites clogs the filters and screens fast.

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.

The character of Khadra

New development: ongoing construction and vacant plots between the homes

A new development district means both the tanks themselves and their surrounding environment are unstable. Cleaning here is not only about removing settled sediment but also managing rapid recontamination from active construction until the district stabilises.

Questions about this district

Does construction work next to our homes affect the tank water quality?

Yes. Ongoing excavation, demolition and heavy lifting raise fine construction dust that penetrates small cracks and openings. After rain you may notice the water goes cloudy much faster than in established districts.

How can we protect the tank from construction debris between cleaning visits?

Inspect the tank lid and seals around access and vent openings regularly. In areas with active construction, you may need more frequent inspection visits than normal before contamination becomes severe.

Do our newly installed tanks need cleaning more often than older tanks elsewhere?

New tanks may need an initial cleaning one month after activation if the area is under active building work. After that, cleaning frequency depends on the quality of water entering the tank, not the tank's age.

Do small cracks in new tanks allow water to leak out?

Hairline cracks rarely leak outward because of water pressure inside, but they do allow fine pollutants, dust and very small insects to enter the tank.

What if the water changes colour quickly after we have it cleaned?

First check the incoming water supply and its filter. If your area is under construction, the water supply itself may carry pollutants from temporary municipal pipework still in use.

Do we need special equipment to clean tanks in newly built districts?

Yes. Fine sand from building materials needs more careful rinsing to avoid re-settling fine dust. High pressure wash is gentler than usual to prevent stirring up and resettling of fine particulates.

How much does water tank cleaning in Khadra 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 Khadra.
