Water Tank Cleaning Step by Step in Jeddah: What to Expect on the Day

The crew usually starts by examining the outside of the tank, the lid, the inlet and outlet pipes and the float, then looks through the opening to estimate sediment, algae, material and workload. That inspection decides the tools, the number of workers and the expected time.

You are entitled to see photos or a description of what the company found before work begins. It documents the starting condition and helps you compare afterwards. If there is visible leakage or damage, note it immediately so it can be handled during or after the service.

Your own preparation helps: clear the path to the tank, make sure the lid opens easily, and show where the water valve is and whether a pump needs to be switched off.

Before draining, incoming water is closed and the pump is stopped so it does not run dry and get damaged. The area around the tank is secured by keeping children and belongings away and marking a warning where needed, especially for roof tanks.

In enclosed spaces the crew pays attention to ventilation and does not let anyone enter before the air is safe. You should store the water you need beforehand, because taps will be dry until the work and refilling are finished.

Agree on a contact number and who stands at the opening during work. These small details prevent confusion.

The tank is emptied, then the last water and liquid sediment are pumped out. The method depends on location, either by gravity or with a drain pump, and the water must be discharged where it will not flood a walkway or bother neighbors.

Watch the color of the last water coming out; if it is very cloudy it hints at how much sediment there is. If you see foreign objects such as plant remains or insects, ask how they got in so the cause can be fixed.

Draining carelessly without a discharge plan can cause problems with neighbors, so you may ask about the plan before work starts.

This is the core of the job: sediment is lifted from the floor and walls with brushes suited to the tank material, and the muddy layer is collected and removed from the tank. Corners and joints get extra care because they hold dirt.

Spraying water on the walls is not enough; stuck sediment needs contact scrubbing. A concrete tank takes longer scrubbing while a plastic tank takes soft tools, and the floor is checked after removal for leftover mud.

Ask to see the opening or a photo of the walls after scrubbing and before disinfection. That is the clearest proof the scrubbing really took place.

After the dirt is removed, the tank is disinfected with a product approved for drinking water and left for the contact time given in the product instructions. Disinfection does not replace removal, because a disinfectant cannot penetrate a thick sediment layer.

Ask for the product name, concentration and contact time, and do not accept vague answers. Unsuitable products can leave an odor or a trace in the water, and wrong doses either damage the tank or fail to do the job.

Never add household products yourself or mix cleaners, because some mixtures release toxic gases. Leave it to the trained crew.

The tank is rinsed thoroughly with clean water until all traces of disinfectant and cleaners are gone, then the surface and odor are checked. The rinse should be a stage of its own, not just a quick spray before refilling.

Then fittings, float and lid are reviewed, since cleaning is a good chance to spot damage. If a small part needs replacing, agree on it before restarting so you do not have to reopen the tank days later.

Make sure the lid is closed tightly after the final check and that any mesh or gasket removed during the work is put back.

The tank is refilled and water is released gradually, then the first water from the taps is run off until it clears. Either the crew or you should look at the color and smell of that first flow, which is the real moment of verification.

It is good practice for the crew to give a short summary: what they found, what they did, and any repair notes. Record the date in the tank log so you can set the next appointment.

Do not hesitate to ask for a follow-up visit if an odor or unusual color appears in the first days of use, because it is quickly solved when reported early.
