Water tank cleaning for homes and businesses

We drain the tank fully, lift the settled layer that stays below the outlet, pressure wash the walls and the floor, then disinfect and put it back into service. The order is the difference between cleaning a tank and rinsing it.

  • Targeted, not broadcast

    Product goes into cracks and runways, never sprayed across open surfaces.

  • Told before we start

    What we will use, where it goes, and what to cover or move before we arrive.

  • A follow-up visit

    We return after the first treatment, because what survives it does not show on the day.

  • Homes and businesses

    Apartments and villas, and kitchens and stores that need a record of each visit.

Why draining and rinsing is not cleaning

Three reasons, and between them they explain why the water clouded again after the last time.

First

The outlet sits above the floor

Water leaves through an outlet set a little above the base, so the settled layer stays underneath it however long the tank is left to empty. Lifting that layer out is the part that gets skipped.

Second

The film on the wall

The wall carries a thin, slick layer that holds onto the surface, and a hose runs straight over it. It comes off mechanically, with pressure and a brush, not with running water.

Third

Disinfectant before the wash is spent

Disinfectant is used up by whatever it meets first. Leave the silt and the film in place and it is consumed by them, never reaching the surface it was meant to treat.

Before treatment

The condition of the tank decides the method

Six things we look at before the drain valve is opened, and each one changes something about what follows.

Fine brown sediment beneath shallow water

The layer on the floor

How deep this layer sits tells us how long it has been building, and that decides whether it comes out by hand or needs a suction pump.

Water turned green by algae

Light and algae

Algae needs light, so finding it points to a lid that does not seat or a wall the sun passes through, and that is dealt with during the visit rather than after it.

A damp concrete wall carrying a dark deposit

The deposit on the wall

It is slick to the touch and grips the surface, and how far it runs up the wall is what decides the length of the pressure wash.

A concrete surface with a fine hairline crack

The lining and hairline cracks

A hairline crack holds water and brings the cloudiness back after every clean, so we record it before the wash and tell you if the tank needs lining work and not just cleaning.

The lid of a water tank on a building roof

The lid and the access hatch

A cracked lid, or one that does not sit flat, lets dust and insects in between visits, and it is the commonest reason cloudiness comes back quickly.

A plastic pipe leaving the exterior wall of a building

The vent and the overflow pipe

Both are open doorways when they carry no mesh, and we note their size because screening them does more good than shortening the gap between cleans.

How the visit runs

Four steps in a fixed order, because disinfecting before the sediment is out is wasted, and washing before the drain means nothing.

  1. 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. 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. 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. 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

  • A technician inspecting with a flashlight

    An inspection before the valve

    Tank type, lining condition, depth of sediment, lid and vent, recorded before any water leaves.

  • A metal floor drain

    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.

  • A spray nozzle in close detail

    Pressure washing walls and floor

    High pressure across the surfaces and corners, and a brush on anything water alone will not lift.

  • A gloved hand applying bait into a joint

    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.

  • A clean kitchen counter after treatment

    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.

  • The visit report being written on a clipboard

    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.

Exactly where the product goes

  • 1

    Inside joints, not on surfaces

    Bait goes into a cabinet joint or a gap behind an appliance, in dots the size of a match head, in places no hand reaches and nothing touches in ordinary use.

  • 2

    Away from where food is

    Nothing is sprayed on preparation surfaces, inside food cupboards, or across open floor in living rooms and bedrooms.

  • 3

    A little preparation first

    Cover dishes, move water bowls. We give you the ventilation time for your treatment on the call, rather than a general number printed on a page.

  • 4

    Tell us the exceptions

    Asthma, an allergy or a pregnancy in the home changes the product choice and the order of the visit. It is a change we make often and it does not delay the appointment.

Common questions

How often does a tank need cleaning?

Twice a year is the common pattern for a home tank, and the interval moves with the water source. A tank filled by tanker takes in more sediment than one fed from the mains, and a roof tank standing in the sun behaves differently from a shaded ground tank. We set your interval from what is actually on the floor this time, not from a general rule. Businesses that need a written record of every visit put the dates inside Annual contracts.

Is washing enough, or does the tank need disinfecting too?

The wash lifts the sediment and the film; the disinfection deals with what you cannot see once the surface underneath is clean. Order is what matters, because disinfectant laid over remaining sludge is consumed by the sludge. We do both in the same visit, and the detail on product and contact time sits on Water tank sterilization.

When can we use the water again?

After the refill, and after the first water has been run off at the taps. The wait changes with the product, the capacity of the tank and how much pipework sits after it, which is why we do not print a fixed number here. We give you yours at the visit, before we start, and we suggest putting aside the drinking water you will need beforehand.

The water went cloudy again quickly. Why?

Three usual reasons. The first is that the settled layer under the outlet was never lifted, so it stirs back up with every fill. The second is dust arriving between visits through a lid that does not seat or a vent with no mesh. The third is a lining that has begun to break down, or a crack that weeps, and that is answered by Water tank sealing or Tank leak repair rather than by cleaning more often.

Do you clean ground and concrete tanks as well?

Yes, and the difference is access rather than method. A ground tank collects more sediment because its hatch sits near ground level, and it needs ventilation, lighting and safe entry before anyone goes down. A roof tank drains more easily but the equipment is harder to get to it. We plan the steps once we have seen the hatch, where it sits and how big the tank is.

We keep finding insects and geckos around the tank. Is that connected?

Usually yes. An unscreened vent and a lid that does not sit flat are direct routes to the water, and standing water around an overflow pipe on a roof is enough on its own to become a mosquito breeding site. We record the openings and their sizes in the visit report, and where breeding is already running, Mosquito control covers how it is handled.

What does water tank cleaning cost?

It is set once we know the tank: its capacity and type, where it sits and how easily we reach it, how much sediment is on the floor, and whether it needs disinfection only or lining work as well. Send the capacity and a photo through the hatch if you can on WhatsApp, and we will give you an estimate before we come out, then confirm it at the inspection.
