Water tank cleaning in Jaranah Makkah

Jaranah is a wadi settlement at the north eastern edge of the Haram, home to Al Jaranah Mosque the pilgrimage point for umrah, with scattered low houses, old wells, farms in the wadi bed and open ground around the settlement. Tanks here absorb contamination from seasonal floods and high groundwater, fertiliser seepage from neighbouring farms, and direct leakage from old wells that stand metres away from homes.

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.
Ground and roof tanks

Villas, apartment blocks and premises that need a written record of each visit.

Why the job is different in Jaranah

Tanks here suffer seasonal floods and high groundwater, fertiliser from farms and direct contamination from old wells, with pollution entering through multiple pathways. The method is set out in full on what Water tank cleaning involves.

The first reason

Seasonal floods carry polluted wadi water into the tanks

Wadi Al Jaranah carries water down from the hills after rain, and floods may enter ground tanks or inundate the area. Water from the wadi carries soil and organic contamination.

The second reason

Farm fertilisers fuel algae and fungal blooms

Farms ring the homes and wells in Jaranah, and fertilisers enter the tank through groundwater or seepage. Algae bloom rapidly when excess nutrients arrive.

The third reason

Old wells leak contaminated water directly into the tank

Ancient wells near homes may leak, and groundwater draws bacteria and organic contamination. A ground tank near an old well may receive polluted water directly.

Before treatment

The condition of the tank decides the method

Jaranah is a rural area in a wadi east of Makkah with farms and old wells and scattered dwellings on open ground throughout the settlement.

Fine brown sediment beneath shallow water

The layer on the floor

The floor collects heavy sediment from floods, groundwater and settled fertiliser particles from surrounding farms.

Light and algae

Light and algae grow rapidly from excess nutrients in groundwater and farm runoff.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Wall deposits build from sediment and mould from high moisture and organic contaminants.

A concrete surface with a fine hairline crack

The lining and hairline cracks

The plastic lining may crack from groundwater pressure and seasonal flood stress.

The lid and the access hatch

The lid and access hatches may be inundated by floods or leak from inside pressure.

Vent openings and overflow pipes clog from sediment, algae and mould growth from moisture.

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

Do floods in the wadi enter the ground tank directly?

Floods may inundate the area and enter ground tanks if they are not sealed properly. Floodwater contains organic sediment and soil.

Do farm fertilisers contaminate the tank water?

Yes, fertilisers enter groundwater and the tank. Algae grow rapidly when excess nutrients arrive.

Why does water sometimes smell strange from old wells?

Ancient wells may leak water containing hydrogen sulphide gas or bacteria. Tank cleaning and regular well inspection are needed.

Should we protect the tank from seasonal floods?

Raising the tank above ground level or protecting it with barriers helps. Cleaning after heavy floods is essential.

Does high groundwater cause tank leaks?

Yes, high groundwater table presses on ground tanks and may cause leaks. Regular leak inspection is needed.

Is tank cleaning enough or do we need to repair the wells?

Tank cleaning removes current contamination, but if the well is leaking polluted water, inspection and repair may be necessary.

How much does water tank cleaning in Jaranah 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 Jaranah.
