Water tank cleaning in Al Nakhil Jeddah

Al Nakhil is a mixed district in eastern Jeddah between Palestine Road and the King Abdullah branch road, with shops at street level, apartments and villas above them, and recent housing schemes. Al Nakhil Park and the walking promenade give the district a lively and attractive character, but tanks beneath mixed use buildings serve both shops and flats together with constantly shifting, competing pressure. Demand is uneven and the tank must serve both commercial kitchens and residential floors with no way to balance the load.

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.

Why the job is different in Al Nakhil

Shop and flats share one tank. When the shop opens its tap in the morning, water cuts to the upper flats. Usage is wildly uneven throughout the day. The method is set out in full on our Water tank cleaning service.

The first reason

Shops and flats compete for pressure in one shared tank

Shops need hot water for cleaning and cooking all day. Flats need cold water for drinking and domestic use. Pressure never balances, and the tank endures constant fluctuation.

The second reason

Gardens and irrigation around the area drive moisture and algae

Al Nakhil Park and the promenade need constant watering. High humidity around tanks speeds algae and bacterial growth, and excess irrigation water may approach underground tanks.

The third reason

Steam and light oils from shops below rise into the tank

Food shops and restaurants at street level cook all day. Steam and light oil vapours rise towards tanks above them, leaving oily deposits on walls and surfaces.

The character of Al Nakhil

Mixed district: shops at street level with homes above them

A mixed district with shops below and flats above means tanks serve wildly different usage patterns. Shops need hot water constantly, flats need cold water, so pressure never balances. Contaminants differ from purely residential areas, and cleaning must account for all these competing pressures and sources of contamination.

Before treatment

The condition of the tank decides the method

A developing district in eastern Jeddah that mixes recent housing with commercial ground floors. Proximity to parks and gardens means continuous water demand for irrigation that feeds into the general supply network.

Fine brown sediment beneath shallow water

The layer on the floor

Tank floors in Al Nakhil collect silt and sand from excess irrigation around the district, and an oily layer of cooking fats and oils from shops below the tank. Strong flushing with mild detergent removes this layer.

Light and algae

Light and moisture from nearby gardens speed algae growth on tank walls, particularly in summer when gardens are irrigated heavily.

A damp concrete wall carrying a dark deposit

The deposit on the wall

Tank walls carry an oily layer from kitchen fats and cooking oils. High pressure washing with mild detergent removes this layer without damaging the surface.

A concrete surface with a fine hairline crack

The lining and hairline cracks

Hairline cracks may appear from high moisture and vibration from the flat above and shop below. Regular inspection catches early cracking.

The lid and the access hatch

Lids and access hatches collect leaves from nearby trees and road dust. Cleaning includes clearing these openings and protecting them from leaves and dust.

The vent and the overflow pipe

Vent and overflow openings need protection from insects and leaves from nearby gardens. Cleaning includes installing strong mesh screens that resist fallen leaves.

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 Umm Al Salam Sub-Municipality

The Umm Al Salam sub municipality covers the east and south east of Jeddah along the Old Makkah Road and the Haramain Road. It pairs recently planned districts such as Al Wahah, Al Nakhil and Al Shuruq with popular districts that grew outside formal planning, including Al Harazat, Al Mahamid and Umm Al Salam. The older areas have ageing drainage, unpaved streets and vacant plots where building waste collects, conditions that suit rodents, cockroaches and ants. The newer areas are ringed by half built subdivisions and open excavations.

Questions about this district

Shop and flat share one tank. Water cuts when the shop opens?

The shop consumes water faster than the flat. The shared tank cannot refill fast enough. Cleaning improves pressure slightly, but the root problem lies in the design.

Water from the flat above the shop runs cloudy but the next flat is clear?

The flat sits directly above the shop. Steam and oils rise and settle in the tank. Cleaning removes deposits, but steam returns with every business day.

Al Nakhil Park is close to the tank. Could excess irrigation water enter it?

Continuous watering raises soil moisture around tanks. Water may seep in through small cracks. Inspection and cleaning reveal any leaks.

The Al Nakhil Promenade is packed with people and shops. Does that affect the water?

The activity and commercial traffic mean water consumption is very high from shops and cafes. Pressure fluctuates constantly and the tank runs under continuous strain.

Water from the flat has an odd light colour. What causes it?

Light oils and grease from the shop float on the tank surface. Water drawn from the top may carry these oils. Cleaning removes this layer.

Is Al Nakhil tank cleaning different from a purely commercial district?

Yes. Al Nakhil mixes shops and homes, so pressure and contaminants differ from a purely commercial area. Cleaning must account for all competing uses.

How much does water tank cleaning in Al Nakhil 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 Nakhil.
