Why the job is different in Hatim

Tanks in Hatim fill slowly and carry heavy silt from the floor of Wadi Al Sharai, especially after the rain season when runoff flows through the valley. The method is set out in full on our Water tank cleaning service.

The first reason

Wadi Al Sharai carries heavy silt from farms and agricultural land

Hatim sits on Wadi Al Sharai which carries both irrigation and flood water, and silt from farmland settles in the wadi and enters the network that fills the tanks.

The second reason

Agricultural land raises humidity and salt around tanks

Farms around Hatim raise the water table and humidity, and tanks standing on farmland may absorb moisture and salt from the soil surrounding them.

The third reason

Network pipes cross salt and silt laden farmland

Pipes routed through wet farmland and agricultural zones carry deposits of salt, silt and clay, and tanks receive this heavy water directly from the network.

Before treatment

The condition of the tank decides the method

The zone sits on both sides of Wadi Al Sharai with date palms and farms in the valley floor and higher hilly ground rising to the east, with the Taif road cutting through the wadi from the north.

Fine brown sediment beneath shallow water

The layer on the floor

The settled layer on the floor in Hatim is heavy brown silt from thick deposits in Wadi Al Sharai and farmland runoff.

Light and algae

Light enters farm tanks and stagnant water with silt may support light algae growth from salt and nutrients.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Walls carry a brown layer of clay, silt and salt from the wadi and agricultural runoff.

A concrete surface with a fine hairline crack

The lining and hairline cracks

The concrete lining may absorb salt and moisture from the farmland around it, causing cracking and stress fractures.

The lid of a water tank on a building roof

The lid and the access hatch

Tank lids and access ports may be very simple in farm zones, and small animals can easily enter through open hatches.

The vent and the overflow pipe

Ventilation and overflow vents may be clogged with silt and clay, or stand open and allow insects and debris to enter freely.

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 farm tank is very cloudy and full of sand and clay. Why?

Water in Hatim comes from Wadi Al Sharai carrying silt from farmland and floods, and the tank receives this heavy water directly without adequate treatment.

After rain the water goes very dark brown and full of particles. What is the remedy?

Rain flows down Wadi Al Sharai carrying heavy silt from farmland and fields, and the tank receives this thick water and immediate cleaning is essential.

The tank is on farmland and humidity is very high around the footings. Is it dangerous?

Irrigation and groundwater moisture may cause slow seepage around the tank base, and salt from farmland may corrode steel reinforcement in the concrete.

Old farm tank and the water has a very strong salt taste. Why?

Salt in farmland and groundwater raise salt levels, and an old tank may be porous and allow salt to enter from the surrounding soil.

Do we need special filters in Hatim because of all the silt?

Yes, filters and screens are essential in Hatim because water carries heavy silt, clay and salt from farmland and the wadi.

When is the best time to clean the Hatim tank?

Immediately after the rain and flood season is best, because water carries the heaviest silt then and immediate cleaning protects the tank.

How much does water tank cleaning in Hatim 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 Hatim.
