Water Tank Cleaning in Al Baha | Rooftop and Ground Tank Washing, Disinfection and Sealing

Gulf Al Arab Company provides water tank cleaning in Al Baha for rooftop tanks and concrete ground tanks, in plastic, fibreglass and metal. The service covers draining the water, pumping out sediment, washing the walls and floor, disinfecting and rinsing the tank, and checking for cracks and leaks, with tank sealing where needed. A household rooftop tank starts from SAR 120 and a ground tank from SAR 140.

The tank is the source of the water you drink, cook with and wash in. Over time sediment and silt collect on its floor and algae and a slimy film grow on its walls, especially if the lid does not close tightly. This guide explains when your tank needs cleaning, how each type is washed and disinfected, the price of each service, and when a tank needs sealing rather than just cleaning.

Tank cleaning with Gulf Al Arab covers everything a tank needs to be fit for storing water again: inspecting the tank inside and out, draining it with a pump, removing silt and sediment from the floor, washing the walls and inner roof with brushes and a pressure washer, then disinfecting and rinsing, cleaning the lid and vent, and finally refilling and checking that the float valve works.

We serve tanks in houses, villas, residential buildings, mosques, rest houses and shops, whether they sit on the roof or below the courtyard or entrance.

When does a water tank need cleaning?

A tank needs cleaning if the colour, taste or smell of the water changes, if sand grains appear in taps and washing-machine filters, if a slimy film forms on taps, or if more than six months have passed since the last clean. Cleaning at least once every six months is the usual advice, and straight away after any plumbing or renovation work in the house.

Some signs are not visible from the tap but from the tank itself: a broken or loose lid, a vent with no mesh, green algae on the inner walls of a fairly translucent plastic tank, or dead insects floating on the water. All of these mean the tank needs cleaning and a lid repair together.

Rooftop tank washing in Al Baha

Rooftop tank washing starts from SAR 120 for a household tank and includes shutting the main valve, draining the water, removing the lid, vacuuming sediment from the floor, washing the inner walls with soft brushes that do not scratch plastic or fibreglass, then disinfecting, rinsing and refilling.

Rooftop tanks in Al Baha face changeable conditions: strong sun on summer days, sharp cold on winter nights, and fog, rain and wind in the highlands. Heat and light encourage algae inside light-coloured tanks, and wind blows in dust and leaves if the lid is not tight. So we pay as much attention to the inner walls, the lid and the vent as to the floor.

Metal tanks need a rust check at welds and corners; if rust appears we tell you, because cleaning does not cure it and the tank may need an internal coating suitable for drinking water or replacement. Fibreglass tanks are cleaned with soft brushes only, and we check for hairline cracks that appear over time as temperatures swing.

Ground tank cleaning in Al Baha

Ground tank cleaning starts from SAR 140 and includes draining with a submersible pump, removing silt and sediment from the floor, washing the walls and inner roof with a pressure washer and brushes, then removing the wash water, disinfecting and rinsing, and cleaning the tank opening and its cover.

Concrete ground tanks collect the most sediment, because water enters them first from the mains or from water tankers, and sand and silt settle on the floor. Over time the concrete may crack or the inner render may wear, letting water leak out or damp and dust seep in, so we inspect the walls straight after washing while they are exposed.

Going down into a ground tank calls for care, because it is an enclosed, poorly ventilated space. We open the cover and air the tank before entering, use a fixed ladder, keep one worker at the top for the whole job, and never use products with strong fumes inside a closed tank.

Water tank disinfection in Al Baha

Disinfection is part of every clean we do, and it comes after washing and sediment removal, not before, because a disinfectant does not work well on top of silt and slime. We use a disinfectant made for drinking-water tanks at a strength suited to the tank size, spray it over the walls, floor and inner roof, leave it for the required time, then rinse the tank with clean water until the smell is gone.

The disinfectant does not stay in the tank: we discard the first rinse water, then refill the tank and run the taps in the house for a few minutes so old water leaves the pipes. If a faint smell remains in the first water to come out it fades with use, and if you notice any smell we advise not drinking the water during the first hours after disinfection.

We also clean the parts many people overlook: the float valve, the inlet, the vent and the underside of the lid, because they touch the water and collect algae.

Water tank sealing and repair in Al Baha

Sealing is needed when cleaning is not enough: when a ground tank leaks water outward, lets damp and dust in, or shows cracks and worn walls. Fibreglass crack repair starts from SAR 415, while for ground-tank sealing you should ask about the price at the inspection, because it depends on the area, the condition of the walls and the type of coating.

Sealing starts with draining, cleaning and fully drying the tank, then treating cracks and voids, then applying coats of a sealant suitable for contact with drinking water, such as epoxy made for water tanks, then letting it cure for long enough before refilling, and finally rinsing and disinfecting.

Not every sealant suits a water tank; some roof waterproofing products are not suitable for contact with drinking water. So always ask what material is being used and whether it is made for water tanks, and never refill before the coating has fully cured.

A quick comparison of tank types and their weak points:

Tank cleaning steps, from draining to refilling

1. Initial inspection: tank type and size, the condition of the lid and float valve, and any visible leak.
2. Shutting off water: closing the inlet valve and draining the tank with a pump.
3. Sediment removal: silt and sand vacuumed from the floor.
4. Washing: walls and inner roof with brushes and a pressure washer, according to tank type.
5. Disinfection: a drinking-water product sprayed and left for the required time.
6. Rinsing: clean-water rinse, with the first rinse water discarded.
7. Refilling: opening the valve, checking the float and running the taps to refresh the pipes.

How to prepare for tank cleaning day

Water to the house is cut while the tank is cleaned, from draining until refilling, which usually takes a few hours for a household tank. So before the appointment fill a few containers with water for essential use, postpone the washing machine and dishes until after the work, and tell the household when the supply will be off.

If the tank is full and the water fairly clean, it can be used to water the garden or wash the courtyard before draining rather than wasted. Give the crew safe access to the roof or the ground-tank opening, and move cars away from the tank hatch in the courtyard.

Cleaning tanks in buildings, mosques and rest houses

Tanks in residential buildings, mosques and rest houses are larger and serve more people, so contamination has a bigger effect. We coordinate the cleaning time with the owner or person in charge so the water is off for as short a time as possible, notify residents beforehand, and work with a larger crew and stronger pumps so draining, washing and disinfection are finished the same day.

In mosques we choose a time between prayers and pay attention to the tank feeding the ablution areas and toilets, because its water is used heavily and sediment can build up faster.

What contaminates a water tank?

A tank is usually contaminated from five sources: sediment that arrives with the water itself and settles on the floor; a loose lid that lets in dust, insects, leaves and sometimes birds; heat and light that help algae grow in light-coloured tanks; old pipes that carry rust into the tank; and nearby building or plumbing work that brings in cement and dust.

Knowing the source decides the fix: sediment needs regular cleaning, a lid needs replacing, algae needs the tank shaded or a translucent tank swapped for an opaque one, rust calls for a pipe check, and building work needs a clean as soon as it is finished.

Cleaning the tank when you move into a new home

When you move into a new house or apartment, rented or bought, you do not know when the tank was last cleaned or how it was used. So we recommend cleaning and disinfecting the tank before moving in or in the first week, especially if the house was closed for a long time; water standing in a closed tank for months develops a slimy film and a smell.

This can be combined with the move-in house clean on the same day, with the tank crew starting first so the water is clean by the time the cleaning crew begins washing.

Common mistakes when cleaning a tank yourself

• Adding chlorine or bleach without draining the tank and removing sediment, so the disinfectant never reaches the floor and the silt stays.
• Using a lot of household bleach and then not rinsing, leaving a smell and taste in the water for days.
• Using a wire brush on a plastic or fibreglass tank, which scratches the wall and turns the scratches into places for algae to grow.
• Going down into a ground tank alone without ventilation, which is a real danger in enclosed spaces.
• Forgetting to clean the lid, the float valve and the vent, which are among the dirtiest parts.

Tips to keep your tank clean

• Make sure the tank lid is tight and locked, and replace it immediately if it breaks.
• Fit fine mesh over the vent to keep out insects and leaves.
• Do not leave the tank empty for long, exposed to sun and dust.
• Ask the water tanker to be clean, and watch the colour of the water as it fills.
• Clean the tank after any plumbing or building work near it.
• Check the outside of a ground tank for any damp or leakage around it.

How to choose a water tank cleaning company in Al Baha

Choose a company that removes sediment before disinfecting, not after, uses a disinfectant made for drinking water and tells you its name, rinses the tank after disinfection, and goes into ground tanks with clear safety procedures. Ask: do you clean the lid and float valve? Do you check for cracks? What do you use for sealing if the tank needs it?

Clear answers to these questions matter more than the price alone, because a tank that looks clean at the top but still has sediment on the floor or disinfectant residue will bring the same problem back within weeks.
