Tank cleaning in Jeddah starts from SAR 92 for a rooftop tank and from SAR 185 for a small ground tank, rising with capacity, material and condition. These are the starting prices for each type:
| Service | Details | Starts from (SAR) |
|---|---|---|
| Rooftop tank | Fibreglass or plastic: washing and disinfection | 92 |
| Small ground tank | Draining, sediment removal, washing and disinfection | 185 |
| Plastic or polyethylene tank | Washed with soft brushes that do not scratch the wall | 185 |
| Steel or sheet-metal tank | Washing and treatment of visible rust spots | 320 |
| Concrete or fibreglass ground tank | Medium to large capacity | 370 |
| Ground + rooftop for a villa | Both tanks in one visit | 320 |
| Building and mosque tanks | Large capacity or several tanks | 740 |
| Palace and hotel tanks | Very large capacity | 1,380 |
| Tank sealing per m² | Waterproofing for walls and floor | 74 per m² |
| Sika-type sealing | Cement-based coating for walls and floor | 1,100 |
| Epoxy sealing | Smooth sealing layer for a concrete tank | 1,650 |
| Combined sealing | Cement-based plus epoxy depending on condition | 2,300 |
| Leak detection and repair | Depends on location and fault | Ask for its price by phone or WhatsApp |
The price covers the workers, pumps, materials and disinfection. What usually pushes the price up is mud built up over years, a new tank still holding construction debris, difficult access to the tank opening, or several tanks in the same building.
How much does tank cleaning cost in Jeddah? Price factors
Tank cleaning cost in Jeddah comes down to four things: its capacity, its material, its condition and its location. Knowing these before the visit makes the price clear from the start.
Capacity
A one or two-tonne rooftop tank is quick, while a ground tank in an apartment building may need a bigger pump and two workers inside.
Material
Concrete is a rough surface that holds sediment and needs harder scrubbing; fibreglass and plastic are smoother and quicker to wash.
Condition
A tank neglected for years, or one that insects or mud have got into, needs more time and materials.
Location
A narrow opening, a tank under a car park, or one on a high roof with no fixed stairs all affect working time.
The easiest way to get an exact price is to send us a photo of the opening from above and one of the area around it, with an estimate of the capacity in tonnes or the tank dimensions if you know them. A tank three metres long, two metres wide and two metres deep, for example, holds about 12 tonnes. Knowing this helps us choose the pump size and the number of workers before arriving, so the price does not change at the door.
Two questions come up often. Is disinfection charged separately? No, disinfection is part of the washing in all the prices above. Do prices differ between a ground and a rooftop tank of the same size? Yes, the ground tank costs more because working inside it is harder and needs pumping, ventilation and a secure ladder.
Water tank cleaning services in Jeddah
In Jeddah we wash, disinfect, desludge and seal tanks, check them for leaks and repair their fittings. Here is what each service includes:
Ground tank cleaning
Ground tank cleaning starts from SAR 185 for a small tank and from SAR 370 for a large concrete one. The ground tank needs the most care because sediment sinks to its floor, and because many Jeddah homes fill their tanks from water trucks, which bring a little sand and silt with every delivery. We open the lid carefully, especially heavy concrete lids, lower a secured ladder, then pump the water out and leave a small amount for washing.
After draining, the worker scrubs the walls and floor with suitable brushes, focusing on the corners between wall and floor and the area under the filling inlet, where mud collects most. The dirty water is then pumped out, the tank is rinsed with clean water, disinfected, and rinsed again before refilling.

Rooftop tank washing
Rooftop tank washing starts from SAR 92 and covers draining, washing the inner walls, disinfection and cleaning the lid and openings. Rooftop tanks in Jeddah are usually fibreglass or plastic and sit in direct sun, and if the tank lets a little light through or its lid is loose, green algae grow on its walls.
We clean rooftop tanks with soft brushes that do not scratch the inner surface, because scratches later become places where dirt clings. We also check the float valve and the inlet and outlet valves, and make sure the vent is covered with mesh to keep out insects and dust.

Water tank disinfection
Disinfection is included in every wash and is done after scrubbing and the first rinse, not before, because a disinfectant does not work well on a muddy surface. We use chlorine compounds approved for drinking water at a strength calculated for the tank’s capacity, leave them on the walls long enough, then rinse so no chlorine smell stays in the water.
After refilling you may notice a faint chlorine smell the first time you use the water. This is normal and goes once the taps run for a little while. If the smell stays strong, tell us and we will check the rinse.

Sediment and mud removal
Sediment removal is the heart of ground tank cleaning. We use a submersible pump that draws out water with the mud and sand from the floor, then remove what remains by hand with rubber squeegees and buckets. The pumped water is directed to the nearest suitable drain so it does not pool outside the house.
Tanks that have not been cleaned for years may hold a thick layer of mud, and new tanks sometimes contain building debris such as cement, plastic and pieces of wood. All of this comes out before washing, and it may take extra time that we tell you about before we start.

Tank sealing in Jeddah
Tank sealing starts from SAR 74 per square metre and is needed when damp appears around a ground tank, its walls crack, or water use rises with no clear reason. Sealing closes the fine pores in concrete, stopping water escaping into the soil and stopping ground or waste water getting into the tank.
Before sealing, the tank has to be completely clean and dry, so we wash it, let it dry, treat the cracks and then apply the sealing material in layers. These are the common sealing types in Jeddah and how they differ:
| Sealing type | When it suits | Note |
|---|---|---|
| Cement-based (e.g. Sika) | Concrete tank in good condition with light damp | Tolerates contact with water, applied in two coats |
| Epoxy | Concrete tank that needs a smooth, easy-to-clean surface | Reduces sediment sticking and needs a fully dry surface |
| Combined | Old tank with cracks and clear damp | Crack repair, then cement-based, then a final coat |
| Rust treatment and coating | Steel and sheet-metal tanks | Rust removal, then a coating made for water tanks |

Tank leak detection and repair
If your water bill rises or the water truck delivery runs out faster than usual, there may be a leak in the tank or its lines. We check the tank after draining, watch the water level after refilling, and inspect the float, valves and connected pipes. The price of leak detection and repair depends on the location and the fault, so contact us by phone or WhatsApp for its price.
Water line and float valve cleaning
After the tank is washed, some sediment caught in the pipes may come out of the taps, so we open the valves gradually and let the water run until it is clear. We also check the float valve, because a faulty float makes the tank overflow or fail to fill, and we replace it if you ask.
Types of tanks we clean in Jeddah
We clean every type of water tank used in Jeddah, each with the method that suits it:
Concrete
The most common for ground tanks; its porous surface holds sediment, needs hard scrubbing and sealing every few years.
Fibreglass
Light and rust-proof, used both underground and on roofs, and washed with soft brushes.
Plastic and polyethylene
Common on rooftops and easy to wash, but affected by sun and prone to algae unless opaque.
Steel and sheet metal
Less common today; needs checking for rust and treatment of corroded spots.
Why water tanks in Jeddah need more care
Jeddah tanks get dirty faster for three reasons: high heat most of the year, frequent filling from water trucks in many districts, and humidity that speeds up rust in metal fittings. Warm, still water is a good environment for algae and bacteria if there is sediment for them to feed on.
A rooftop tank heats up during the day, and if its lid is loose, dust gets in with every storm. A ground tank receives the sand that the water truck carries, and it builds up on the floor layer after layer. That is why a regular cleaning schedule matters more than any product we add, because removing the sediment takes away the place where germs live.
Tip: Write the date of the last wash on a label near the tank valve or in your phone, so you are reminded of the next one without relying on memory.
How Gulf Al Arab cleans a water tank
We follow fixed steps from shutting off the supply to refilling, and each step has a reason:
- Stop the inflow: we close the filling valve or ask you to postpone the water truck.
- Drain: we pump out the water, leaving a little for washing.
- Remove sediment: mud, sand and debris come out of the floor.
- Scrub: walls, floor, the underside of the roof and the corners.
- First rinse: with clean water to flush out loosened dirt.
- Disinfect: with drinking-water-approved products at a strength suited to the capacity.
- Second rinse and inspection: we make sure there is no smell and check the walls, float and pipes.
- Seal the lid and refill: we close the lid tightly and open the inlet valve.
Safety note: A ground tank is a confined space with little air, so never go down into it yourself or let a worker go in without ventilation, a fixed ladder and someone watching from outside, and never use strong household cleaners inside the tank.
Common tank cleaning mistakes to avoid
The most common mistake is adding chlorine to the water without draining the tank and removing its sediment, which leaves the mud on the floor so contamination returns within days. Other mistakes we see often:
- Using household cleaners: such as bathroom cleaners or scented products, which are not made for drinking water and leave a taste and smell.
- Scrubbing a plastic tank with wire brushes: it scratches the wall so dirt sticks faster.
- Cleaning the rooftop tank before the ground tank: unclean water then rises from the ground tank into the clean rooftop one and the work is wasted.
- Leaving the lid open after washing: even for a few hours, letting dust and insects back in.
- Not rinsing after disinfection: leaving a strong chlorine smell in the water.
- Entering a ground tank without ventilation: a real danger to the person going in.
Avoiding these mistakes makes the wash last until the next one and protects pipes and water heaters from sediment.
How often should a water tank be cleaned in Jeddah?
A home tank in Jeddah should be cleaned at least every 6 months, tanks in busy buildings and mosques every 3–4 months, and any tank straight away when the water changes colour or smell. The heat speeds up algae and bacteria, and truck deliveries keep bringing in sand, so we do not recommend leaving a tank for a whole year.
| Building type | Suggested frequency | Reason |
|---|---|---|
| Apartment or small villa | Every 6 months | Normal use and frequent filling |
| Large villa with several tanks | Every 6 months per tank | Large ground tanks that collect sediment |
| Residential building | Every 3–4 months | High use and daily filling |
| Mosque, school or restaurant | Every 3 months | Large numbers of users, ablution or food use |
| After building or renovation | Before first use | Building debris and cement dust |
Signs your tank needs cleaning
Your tank needs cleaning if the water shows a colour, smell or unusual taste, if you see sand at the bottom of glasses, or if tap and water-heater filters keep clogging.
- Yellowish or brownish water after filling.
- A musty or rotten-egg smell when you open the tap.
- Grains of sand or silt in the basin or the washing-machine filter.
- A green or slimy layer on the walls of the rooftop tank.
- Insects or mosquitoes around the tank opening.
- More than 6 months since the last clean.
Tip: If there are children or elderly people at home, keep a fixed tank wash every 6 months and do not wait for a sign, because some contamination cannot be seen.
How long does tank cleaning take?
A rooftop tank takes about an hour, a medium ground tank about two hours, and large building tanks 3 hours or more. The job is shorter if the tank is nearly empty when we arrive, so we recommend cutting back on filling the day before.
While we work the water to the house is off, so fill a few containers for essential use. Ground tanks need refilling afterwards; if your home relies on a water truck, book it for an hour after the expected finish time.
What to prepare before the tank wash
Prepare for the appointment by lowering the water level, storing water for essential use and making the opening easy to reach. These steps shorten the job and reduce wasted water:
- Hold off the water truck the day before and use up as much of the tank as you can.
- Fill containers for drinking, cooking and ablution during the hours without water.
- Move cars or items parked on top of the ground tank lid.
- Have the roof-door key ready if the rooftop tank sits on a locked roof.
- Tell us if the tank is new or has not been opened for years so we bring the right equipment.
Checking water quality after tank cleaning
After refilling, the water should be clear, with no colour, smell or odd taste. We fill a clear glass from the tap in front of you to check it, and inspect the tank after filling to make sure nothing is floating.
If you want an accurate test for salt levels or bacterial contamination, that is done in specialist laboratories using a water sample taken a few days after cleaning. A simple home TDS meter gives a general indication of dissolved salts, but it does not detect bacteria, so do not rely on it alone if the water is drunk directly.
Cleaning a tank after new construction or renovation
The tank in a new house needs washing and disinfecting before its first use, even if it looks clean. During construction it collects cement dust, bits of wood and plastic and sometimes mixing water, which give the water colour and smell and leave sediment in the pipes.
In that case we remove the debris by hand first, then wash the walls and pump out the dust, and check the concrete surface to see whether it needs sealing before filling. It is cheaper to seal at this stage, before the tank is full, because sealing years later means draining and drying it all over again.
How to choose a tank cleaning company in Jeddah
Choose a company that drains the tank completely, removes its sediment, scrubs its walls and disinfects it with drinking-water-approved products, not one that simply adds disinfectant to the water. These questions reveal how a company works:
- Will the tank be fully drained and the sediment removed from the floor?
- What disinfectant is used, and is it made for drinking water?
- Does the worker use ventilation and a fixed ladder inside the ground tank?
- Are the lid, float and vent checked after washing?
- Is the price clear before starting, and what could change it?
At Gulf Al Arab we explain these points before the appointment, and we go over the tank with you after the job so you can see its condition before it is closed.
Tips to keep your water tank clean
A tank stays clean longer when it is tightly closed, kept away from sources of contamination and has its fittings checked regularly:
- Make sure the tank lid fits tightly and has a weight or lock so it cannot be opened easily.
- Cover vents with fine mesh to keep out insects and dust.
- Keep a good distance between the ground tank and the septic tank, and watch for any sewage smell near the tank.
- Do not plant trees near a ground tank; roots can crack its walls.
- Choose an opaque rooftop tank that does not let light in, to stop algae.
- Ask the water truck driver to clean the hose before putting it into the tank opening.
- Fit a filter on the inlet line if the water carries a lot of sand.
Cleaning tanks in apartment buildings, mosques and businesses in Jeddah
Cleaning tanks in buildings and mosques starts from SAR 740, and we schedule it at low-use times so residents are not without water for long. In apartment buildings we tell the caretaker or owner when the water will be off so residents can be informed. If the building has a ground tank and rooftop tanks, we clean them in one visit in the right order: the ground tank first, then the rooftop tanks, so unclean water from below does not rise into the clean tanks above.
For mosques we pick a time between prayers and make sure water is back before the next prayer. For restaurants and businesses that use water in food, we set up a regular schedule, and a full clean of the premises can be booked with it.
