Water tank cleaning in Al Khalidiyah Makkah

Al Khalidiyah is a south western district between Al Hindawiyah and Al Shawqiyah, with land grant plots and traditional houses beside a wide unplanned area on hillsides. Small public gardens and quiet residential streets keep the setting away from the central crowds. Many villas are recent, with exposed rooftop tanks that bake in the sun and face moisture year round. Unplanned areas on the slopes around the district shelter rodents and reptiles. After rain the groundwater approaches the villas and seeps into tanks through fine cracks.

Why the job is different in Al Khalidiyah

In Al Khalidiyah among villas and public gardens, the rooftop tank bakes in full sun and holds moisture, and after rain groundwater rises close to the villa. The method is set out in full on how we approach Water tank cleaning.

The first reason

Unplanned land and vacant plots shelter rodents and reptiles that find entry ways

Wide unplanned areas on hillsides around Al Khalidiyah have vacant plots and open excavations. These are shelter for rodents, snakes and reptiles. Public gardens nearby attract insect colonies. These contaminants enter the tank through vents and cracks, especially after rain when the soil becomes saturated.

The second reason

Direct sun on the exposed rooftop speeds algae growth and heat stress

Al Khalidiyah has many recent villas with rooftops fully exposed to sun all day. Tank temperature rises sharply and water becomes ideal for algae. Algae grow rapidly in warm water and light, even with a tight cover. The intense heat of summer strains old pipes and seals.

The third reason

Unplanned areas after rain raise moisture and push up groundwater

After heavy rain open excavations in vacant plots fill with water and mud, and groundwater rises near the villa. High moisture enters the tank through fine cracks and vents. Contaminated groundwater may seep into weak villa pipes and return to the tank.

Landmarks of Al Khalidiyah

Al Khalidiyah has villas scattered around gardens and between the second and third ring roads, meaning the cleaning team reaches villas via quiet residential streets away from crowds, but may need to travel between dispersed sites around the ring roads.

Before treatment

The condition of the tank decides the method

Al Khalidiyah is a district of villas and gardens in south west Makkah with ring roads and residential streets, ringed by unplanned areas on the hillsides.

Fine brown sediment beneath shallow water

The layer on the floor

The floor in new villas collects construction dust residue and mineral salts from groundwater in the early period.

Light and algae

Walls exposed to direct sun accelerate green algae growth even in a brand new tank.

A damp concrete wall carrying a dark deposit

The deposit on the wall

The deposit on walls is light in new villas but grows rapidly from sun and moisture.

A concrete surface with a fine hairline crack

The lining and hairline cracks

New concrete lining develops fine cracks from expansion and contraction in intense summer heat.

The lid of a water tank on a building roof

The lid and the access hatch

New villa covers are better but openings and vents may not protect against small reptiles and insects.

A plastic pipe leaving the exterior wall of a building

The vent and the overflow pipe

Overflow and vent pipes in new villas are clean but may need additional insect filters.

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 Misfalah Sub-Municipality

Al Misfalah sub municipality runs downhill from the south of the Grand Mosque through Al Misfalah, Kudai and Al Rawabi to Al Taqwa, Al Hindawiyah, Al Khalidiyah and Al Rusayfah at the third ring road. The northern end is old apartment blocks and pilgrim hotels with restaurants along Ibrahim Al Khalil Street and the huge coach parks at Kudai. The south and west are dense popular districts with countless small shops and unplanned hillside housing, some of it already cleared for redevelopment, giving way to orderly land grant schemes in Al Rusayfah beside the railway station.

Questions about this district

Do the public gardens and vacant plots beside the villa raise dust that enters the tank?

Yes. Vacant plots and open excavations raise dust especially in wind. Public gardens attract animals and insects. Dust and contaminants enter through simple ventilation holes.

The new villa and new tank run cloudy water after heavy rain. What is the cure?

Groundwater rises after rain and clay enters the tank through fine cracks in the new concrete lining. The new tank may contain construction debris dust. Full cleaning and disinfection, then improve covers and filters.

Can snakes and reptiles from vacant plots enter the tank?

Snakes and reptiles live in vacant plots and excavations. They seek water and may enter through simple vents or cracks. Improving covers, filters and ventilation is essential.

Should the new villa tank be cleaned before occupancy or after the first fill?

Cleaning before first use is essential. A new tank may carry construction dust and metals from pipes. The first fill often brings cloudy water and may contain cement residue.

Is Al Khalidiyah tank cleaning different from an older district like Al Hamdaniyah?

Yes. Al Khalidiyah has new villas and exposed rooftops that need protection from sun and insects. Al Hamdaniyah is an old dense block district with completely different problems.

How often must the new villa tank be cleaned in year one?

In year one after occupancy, cleaning every three months at minimum. The new tank may carry residue and receive contaminants from the neighbouring vacant plots. After year one, every six months is adequate.

How much does water tank cleaning in Al Khalidiyah 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 Khalidiyah.
