Why the job is different in Al Khansa

In crowded Al Khansa near the Grand Mosque, the shared tank endures fluctuating pressure from dozens of flats, and water cuts off at upper floors at peak pilgrimage times. The method is set out in full on what Water tank cleaning involves.

The first reason

Dense district around the Grand Mosque and busy Al Hajj Street raise dust and pollutants

Al Hajj Street is one of Makkah's most congested routes, and cars, buses and pilgrims constantly raise dust. The dense housing around the Grand Mosque means vent holes are close to the street and its pollutants. Dust enters the tank easily, and bacteria from pilgrims may enter via weak pipes.

The second reason

One tank for dozens of residents and daily pressure swings speed corrosion

Al Khansa is very densely built and one old tank may serve thirty flats or more. Pressure drops at upper floors and pressure cycles constantly. This accelerates pipe and filter corrosion, and mineral sediment accumulates in the tank floor at speed.

The third reason

Al Adl cemetery and narrow streets bring smells and bacterial contamination

The nearby Al Adl cemetery and narrow streets ringed by shops and eateries bring moisture and strong odours. Bacteria from the cemetery, kitchens and the crowded pilgrimage air around the Grand Mosque enter the tank through simple vents. Disinfection here must be very strong.

Before treatment

The condition of the tank decides the method

Al Khansa is a crowded district with many residents between Al Hajj and Al Abtah streets, close to the Grand Mosque, with the Al Adl cemetery on its edge, and very narrow dense streets.

Fine brown sediment beneath shallow water

The layer on the floor

The floor collects a thick layer of sediment and rust from old pipes and pressure cycling.

Light and algae

Walls carry black and green bacterial patches from high humidity and dust from Al Hajj Street.

A damp concrete wall carrying a dark deposit

The deposit on the wall

The deposit on walls is layered rust, salts and bacteria colonies that need repeated scrubbing and strong disinfection.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Fine cracks and weak lining allow moisture and pollutants from the street and surroundings to seep inward.

The lid of a water tank on a building roof

The lid and the access hatch

Cover and simple vents carry dust and pollutants from Al Hajj Street and nearby shops, needing vigorous rinsing.

The vent and the overflow pipe

Overflow and vent pipes carry dust and bacteria from the street and may need additional filters.

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.

Questions about this district

Do new pilgrims cause more sediment and contaminants in the tank during the season?

Yes. Pilgrimage seasons raise temporary residents sharply. The shared tank empties faster and polluted water from heavy use returns to the tank. Sediment accumulates rapidly during these peak seasons.

Water cuts off for hours at the flat tap at peak morning and evening. Why?

The tank is small for the population. At peak times dozens of people use water together and the tank empties fast. Old pipes may also leak, so the tank does not hold water.

Upper flat water is cloudy but the lower flat is clear. Why?

The upper flat is distant from the tank, and long pipes carry sediment and rust. Water sitting still in the pipes overnight rusts and turns cloudy in the morning. The lower flat is close to the tank and receives fresher water.

Is Al Khansa tank cleaning different from a quiet low density district?

Yes, greatly. High density and pressure swings make cleaning harder and intervals shorter. The tank here needs cleaning every three months instead of six.

Does busy Al Hajj Street with heavy traffic and pilgrims raise dust into the tank?

Yes. Al Hajj Street is one of the most congested, and dust rises to flats and tanks. Simple holes and cracks allow dust and pollutants from the street to enter.

Al Adl cemetery is near the tank. Does it cause pollution or dangerous bacteria?

Cemeteries do not pollute water directly but surrounding moisture and bacteria may enter through vents. Strong disinfection is essential in a district with a cemetery near the tank.

How much does water tank cleaning in Al Khansa 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 Khansa.
