Why the job is different in Al Mursalat

Hotels and apartment blocks draw water heavily during congregational prayer times and Iftar and in the days leading directly to Hajj, placing intense sustained stress on tanks that causes internal wall seepage in weaker structures. The method is set out in full on how we approach Water tank cleaning.

The first reason

Pilgrim hotels drain a tank in hours

Hotels on this stretch take hundreds of guests at Hajj time, and each one showers, cleans and drinks. A single tank can empty completely in two or three hours flat. This sudden severe pressure causes vibration that cracks pipes and widens fractures in the concrete tank walls.

The second reason

Contaminated water flows back into the tank from pipes

When pressure drops suddenly from full to empty, water in the pipes reverses and flows back toward the tank instead of falling away. That backflow carries bacteria from the mains, showers and kitchen lines back into the tank. Every empty and refill cycle partly recontaminates what has just been cleaned.

The third reason

Internal humidity from heavy daily use

Humidity and steam from hundreds of daily showers raises interior moisture to levels far above normal, and the tank sits in a deeply humid microclimate. Mould and algae grow on inner walls at unnatural speed, and constantly damp surfaces deteriorate far faster than dry ones.

Before treatment

The condition of the tank decides the method

The district sits on a major transit route from King Khalid Road toward Mina, with tall buildings standing close together and a complex residential network serving rapid turnover.

Fine brown sediment beneath shallow water

The layer on the floor

Sediment on the floor here is a mixture of calcium, magnesium and rust together because hard water passes through at high speed and does not settle evenly.

Light and algae

Algae and mould grow quickly on walls because humidity from heavy bathing rises to ceiling and walls, and water perspires inward from the pores.

A damp concrete wall carrying a dark deposit

The deposit on the wall

The concrete inner surfaces carry a red layer of rust and a black layer of mould at the same time, requiring hard scrubbing and strong cleaning agents.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Hairline cracks widen because of repeated high pressure, and water seeps through them slowly, a slow drip in a busy hotel means water loss all day long.

The lid of a water tank on a building roof

The lid and the access hatch

The tank lid faces heat and humidity together, hinges rust rapidly, and the seal can fail after a year of heavy use.

The vent and the overflow pipe

The overflow pipe in a busy hotel may run constantly because frequent pumping fills the tank faster than overflow can drain. Rebalancing the overflow system is necessary.

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 Aziziyah (Makkah) Sub-Municipality

Al Aziziyah sub municipality runs from the Bin Dawood markets to the Al Hada road and carries pilgrim traffic to Mina. Hotel towers and furnished apartment blocks fill and empty with the Hajj and Ramadan seasons, and the kitchens, restaurants and markets along Al Masjid Al Haram Road and King Abdulaziz Road leave food waste at every peak. Southwards the fabric loosens into villas and planned streets in An Naseem and Al Awali, then Al Abidiyah's campus and the old farms of Al Husayniyah, where Wadi Uranah holds water after rain and farm enclosures shelter rodents and reptiles.

Questions about this district

Water cuts out suddenly in a hotel at peak time. Is the tank empty?

The tank may be full, but pressure collapsed from sudden massive demand. Or the inlet valve closed under the load. In a large hotel, water cuts not because the tank is empty but because the mains cannot supply the volume being drawn.

Does cleaning the tank fix water supply cuts at peak times?

Cleaning removes sediment that might partially block the outlet, but it does not increase tank size or improve mains pressure. If a hotel draws more water than the tank holds, you need a second tank or stronger pump.

The hotel water has a strong mineral taste. Where does that come from?

Strong mineral taste comes from very hard water or rust in the pipes. Repeated high pressure stress causes microscopic cracks, and water mixes with rust inside. Cleaning the tank does not cure this, but a filter on the tank outlet reduces mineral taste.

Some guest rooms have cloudy water and others do not. Why?

Rooms drawing first from the tank get clean water. Later rooms get water mixed with sediment from the pipes. If the hotel does not use all its water at once, this is normal.

A rooftop hotel tank is very hot in summer. Does that matter?

Yes, very much. Heat speeds bacteria and algae growth, and hot water increases internal pressure on the tank walls. A hotel using hot water heavily needs more frequent cleaning than one using only cold water.

Do the hotel towers around Al Mursalat share one tank or have their own?

Some towers share a single central tank, others have their own. If multiple towers share one tank, cleaning it affects all towers at once, and any fault in it affects everyone together.

How much does water tank cleaning in Al Mursalat 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 Mursalat.
