Water tank sterilization in Al Mudaa Al Jadid Makkah

Al Mudaa Al Jadid is a luxury development district south of Jeddah within Crown Prince schemes, with scattered modern villas and spacious residential plots. Each villa has its own separate water tank requiring individual treatment. Wadi Uranah and deep groundwater affect the raw water quality before sterilization.

  • 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 Al Mudaa Al Jadid

Residential plots here are large and villas are spaced apart, each with its own separate water tank of relatively large capacity. The method is set out in full on how we approach Water tank sterilization.

The first reason

Large individual tanks in villas

Each villa in Al Mudaa Al Jadid has its own separate water tank of significant size. Individual tanks face different contamination patterns than apartment towers and require site-specific treatment approaches.

The second reason

Deep groundwater and mineral scale

Groundwater here is deep and rich in calcium and heavy minerals. Scale and sediment accumulate quickly and distort water taste and colour.

The third reason

Scattered construction and extended finishing

Villas build more slowly than towers and the construction and finishing period is longer. Tanks may remain filled with contaminated water for an extended period before completion.

Landmarks of Al Mudaa Al Jadid

Al Mudaa Al Jadid lies south of Al Ukayshiyah along Ibrahim Al Khalil Road, with key landmarks being Wadi Uranah running through the district, Jabal Labanah rising to the northeast, and the southern Haram boundary marker at the edge of Al Ukayshiyah.

Before treatment

What we read inside the tank before anything starts

A new residential development district south of Jeddah along Ibrahim Al Khalil Road, containing modern villas and scattered commercial spaces, bordered to the north by Al Ukayshiyah and to the south by Wadi Uranah and Jabal Labanah.

Fine wet sand seen close up

Sediment on the floor

Mineral sediment from hard water rich in calcium, magnesium and iron accumulates at the tank floor.

A concrete wall carrying a damp green layer

The slime film on the wall

Algae and bacteria grow in open, warm tanks during the extended building period.

A plastic water tank standing on a rooftop

Light and heat

Villa supply lines run from the tank to bathrooms, kitchen and outdoor taps.

A concrete surface carrying fine cracks

The lining and any cracking

High humidity, heat and static water create ideal conditions for microbial growth.

A metal cover over a water tank opening

The lid and the openings

The individual tank usually sits on the roof or in the villa courtyard and sediment settles at the base.

What shows up at the tap

Villa water may turn cloudy again after sterilization if particles enter from old external piping.

How we work

  1. 1

    Inspect and record the condition

    We open the hatch and work through what the tank is made of and how big it is, how deep the sediment lies, the state of the lining, whether the lid and the overflow seal, and whether there is a crack that has to be repaired before any sterilizing.

  2. 2

    Drain and lift the sediment out

    The water goes out, then the silt and sand are lifted off the floor by suction rather than pushed toward the outlet, because pushing them sends them into the house pipework and the heater.

  3. 3

    High pressure wash

    Walls, floor, corners and the area around the outlet, until the slime film is completely gone. This is the step that makes the sterilizing after it mean anything.

  4. 4

    Sterilize, rinse, then return to service

    The sterilizing agent goes onto the walls, the floor and the underside of the lid and is left for its contact time, then we rinse, refill and run the furthest tap until the whole line is clear.

What water tank sterilization includes

  • A technician inspecting with a flashlight

    A recorded inspection

    Material, capacity, sediment depth, the state of the lining, the lid and the overflow, all before any work begins.

  • A metal floor drain

    Draining and sediment removal

    The water out, and the silt and sand lifted off the floor instead of being pushed into the outlet and the house pipework.

  • A spray nozzle in close detail

    High pressure washing

    Walls, corners and around the outlet, until the biofilm that no disinfectant penetrates has gone.

  • A spray nozzle in close detail

    Sterilizing the internal surfaces

    A sterilizing agent meant for drinking water tanks, applied to the walls, the floor and the underside of the lid, and left for its contact time.

  • A clean kitchen counter after treatment

    Line flush and aftercare

    Rinse, refill and a flush from the furthest tap, when the water is usable again, and what to change in the filter afterwards.

  • The visit report being written on a clipboard

    The next cycle

    We agree the right interval for your tank from how it is filled, how much sun it takes and the condition of the lid.

What is different about South Makkah Sub-Municipality

South Makkah sub municipality is the belt of Crown Prince schemes south of Al Ukayshiyah, along the Al Laith road and the extension of Ibrahim Al Khalil Road to the Fifth Ring Road and the Non Muslims bypass. Most of it is still bare: granted plots awaiting houses, new villas standing alone, open building sites and unfinished paving and drainage. Wadi Uranah and its tributaries cross the low ground and hold water after rain, hills close it in, and rodents, reptiles and scorpions shelter in stacked materials and foundation pits before the neighbourhoods fill up.

Questions about this district

Why does a single villa tank need different treatment than an apartment tower?

A villa tank is separate and often larger. Water sits static longer and sediment accumulates differently than in towers with continuous pumping.

Is groundwater in Al Mudaa Al Jadid safe to drink without treatment?

Groundwater is rich in calcium, heavy metals and naturally occurring bacteria. Sterilization and filtration are essential to make it safe for drinking.

What causes white scale deposits in tanks here?

Scale is caused by hard water rich in calcium and magnesium. Sterilization does not remove existing scale, but high-pressure cleaning removes it before sterilization.

Is one sterilization enough for a single villa tank?

It may be if cleaning is thorough. But if the tank sits long before actual use, additional sterilization may be needed.

How many times do we purge the villa's supply lines from tank to taps?

Once in the initial treatment, flushing from the furthest tap. But if later contamination appears, we target the specific affected branch.

Do open tanks during construction need extra protection?

Yes. Covering the tank during construction prevents dust, insects and algae from entering. Later sterilization will be easier and faster.

How much does water tank sterilization in Al Mudaa Al Jadid 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 Mudaa Al Jadid.
