Water tank cleaning in Hunayn Makkah

Hunayn sits at the north eastern tip of Al Sharai where Wadi Hunayn meets the Taif road, known today as Al Sharai Al Ulya and home to the village of Sharai Al Nakhl. Running springs still water palm orchards, the historic Hunayn aqueduct arch stands by the Wadi bridge, and the settlement has schools and a clinic, with Jabal Masud to the north. The area is rural and tanks serve scattered homes, but floodwater and silt from the nearby wadi and the farms around it carry rural contaminants unlike those in any town.

Why the job is different in Hunayn

Water here is cool and fresh, but after rain it runs cloudy from wadi sediment. The tank may receive water from a nearby wadi if protection is inadequate. The method is set out in full on what Water tank cleaning involves.

The first reason

Wadi Hunayn brings flash floods and silt after rain

The nearby wadi drains the hills and carries powerful flash floods after rain. Fine silt and sand settle in tanks near the wadi, and water becomes very cloudy.

The second reason

Farms and springs around the home drive high soil moisture

Palm orchards and running springs around Hunayn raise very high soil moisture. Underground and rooftop tanks are affected by soil moisture, and water may seep through cracks.

The third reason

Homes are scattered and tanks are individual and old

Rural homes are spread far apart, each with its own old tank that may have had no maintenance for years. Old tanks leak and crack from soil moisture and mineral salts.

The character of Hunayn

Rural area: farms, open ground and scattered homes

A rural area with farms, springs and scattered homes means old tanks with little regular maintenance. Silt, moisture and rural contaminants differ from urban districts. Cleaning may uncover serious damage that requires complete re lining or replacement.

Before treatment

The condition of the tank decides the method

A rural area far from high population density, yet Wadi Hunayn nearby carries flash floods after rain, and farms and springs affect the quality of groundwater and surface water throughout the area.

Fine brown sediment beneath shallow water

The layer on the floor

Tank floors in Hunayn collect heavy grey silt from Wadi Hunayn after rain. Silt settles fast and is hard to remove. Strong and repeated flushing is necessary.

Light and algae

Light is limited in old rural tanks, but very high moisture from farms and springs speeds bacterial and fungal growth on walls.

The deposit on the wall

Old tank walls carry deposits of mineral salts from groundwater. High pressure washing with mild acid removes these layers.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Hairline cracks are very common in old rural tanks from years of neglect. Moisture accelerates corrosion. Full re lining or replacement may be needed.

The lid of a water tank on a building roof

The lid and the access hatch

Tank lids and access hatches on the rural home are old and often open. Small animals and insects may enter through these openings. Cleaning includes safe sealing and full protection.

The vent and the overflow pipe

Vent and overflow openings on rural tanks lack protection. Small animals and birds may enter or block them. Cleaning includes installing strong mesh screens.

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 Sharai Sub-Municipality

Al Sharai is the eastern growth front of Makkah along King Faisal Road and the Taif road. Settled quarters sit beside recently renamed schemes where plots are still vacant and buildings are going up, so construction sites, fill and open excavations lie next to occupied homes. Wadi channels such as Wadi Mudarraja, Wadi Al Sharai and Wadi Al Mughammas carry flash floods after rain and dry out to damp silt, while dust blows off the open hills. Roadside shops, restaurants and warehouses line the Taif road, and to the east the area shades into villages, palm farms and springs.

Questions about this district

The home is in Hunayn and water turns cloudy after any rain?

Wadi Hunayn nearby carries flash floods and silt after rain. Water may seep into the tank through small cracks in the foundation. Cleaning and inspection are essential after every rainfall.

The tank is very old and leaks water down the outside walls?

Rural tanks have gone unserviced for years. Cracks grow and leaking increases. Cleaning reveals cracks, and full re lining may be needed.

The home sits beside a palm orchard and water feels very damp?

Continuous irrigation of the orchard raises soil moisture around the tank. Moisture seeps through cracks. Insulation and sealing are better than relying on cleaning.

The Hunayn aqueduct arch sits beside the home and water has a metal smell?

The arch is ancient stone, and soil around it may carry old minerals and salts. Groundwater may carry these minerals. Cleaning and disinfection reduce the smell.

Jabal Masud to the north of the home. Does it affect the water?

The hill drains water after rain towards the wadi and homes. Silt and sand may enter the tank if vent openings are unguarded. Protection and cleaning are essential.

Hunayn is an old rural area and the tank is very old. Will it withstand strong cleaning?

Rural old tanks may be very weak. Cleaning with moderate, careful pressure is necessary. Inspection before cleaning reveals whether the tank can take it.

How much does water tank cleaning in Hunayn 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 Hunayn.
