Why the job is different in Zamzam

Tanks in areas with rough terrain suffer from rising groundwater levels during the rainy season, which increases humidity around the foundations. The method is set out in full on Water tank cleaning in detail.

The first reason

Ravines and wadis carry seasonal pollutants directly

Wadi Mudarraja and small ravines around Zamzam carry dirt and particles when rain falls. Tanks near runoff channels need additional cleaning immediately after rain periods.

The second reason

Hilly terrain raises humidity around the tank

Rising and falling ground around Zamzam causes groundwater to collect. Permanent humidity around the tank affects the lining's integrity and speeds the deepening of hairline cracks.

The third reason

Water from the source carries minerals from hilly soil

The hilly terrain in the area is rich in iron and heavy metals that settle on the tank floor in red or brown layers. Regular cleaning is essential to remove these deposits.

Before treatment

The condition of the tank decides the method

Zamzam lies north of the Makkah to Taif expressway between Uhud and Wadi Al Jaranah, with ground cut by ravines that feed Wadi Mudarraja, raising the risk of seasonal contamination.

Fine brown sediment beneath shallow water

The layer on the floor

The sediment layer on the floor in Zamzam contains heavy metals from the hilly soil and appears red or brown.

Light and algae

Light and algae are rare in Zamzam tanks because of high humidity and the cover is usually closed against insects from the wadis.

The deposit on the wall

The deposit on the wall contains iron sediments that are hard to clean and increase with every rainy season.

The lining and hairline cracks

The lining and hairline cracks are affected by permanent humidity around the tank, which speeds their deepening and widening.

The lid and the access hatch

The lid and access hatch must be very tight to prevent insects and moisture from wadis and ravines entering.

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.

Landmarks of Zamzam

Zamzam lies north of the Makkah to Taif expressway, reached from Al Jaranah Road on its western side, with ground cut by ravines that feed Wadi Mudarraja. Tanks distributed across this terrain require special care because of runoff and moisture from these natural features.

Questions about this district

After rain the tank water becomes cloudy. Do the ravines cause this?

Yes, the ravines and small wadis around Zamzam raise groundwater and particles to the surface. Supply water carries sediment from this seasonal surface runoff.

Humidity around our new villa tank is very high even after summer?

The rough terrain in Zamzam traps groundwater. The tank itself may not leak, but the ground around it stays permanently wet because of the ravines and wadis.

The new tank and the soil around the footings is salty. Is that dangerous?

Salt in Zamzam comes from deep groundwater that rises with humidity. This does not directly affect the tank but does increase corrosion of the external lining.

Should the tank be cleaned before the rainy season in Zamzam?

Yes, cleaning before rain ensures the tank is ready for clean water. After rain, additional cleaning removes sediment carried by water from the wadis.

The first water after filling the new tank has odd dampness and particles?

Wet ground around the new tank and slow leakage from the damp lining carries soil particles. The first cleaning and disinfection remove this moisture.

The new tank holds water with a slight earthy smell inside?

Earthy smell comes from wet ground and particles carried by wadis during rain. Regular cleaning and strong disinfection remove the smell.

How much does water tank cleaning in Zamzam 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 Zamzam.
