Not sure whether your tank needs a clean or something more? Our guide on water tank repair, cleaning, and refurbishment explains how to tell which service your home actually needs.

Reasons Why Water Tank Cleaning Is Important

Health and hygiene concerns Using water stored in an unclean tank can become a serious matter. Over time, debris, insects, animal droppings, and even dead organisms can contaminate the water in the tank. This can lead to skin irritations, stomach infections, and waterborne diseases. Regular water tank cleaning helps eliminate these contaminants so the water is safe for everyone in the house.

Prevention of bacterial and algae growth Algae grows in warm, humid conditions and can discolour the water, affect its taste, and clog pipes and filters. Cleaning the water tank at regular intervals removes bacteria, mould, and algae and prevents their regrowth, keeping the stored water safe.

Improved water quality and odour Water from a poorly maintained tank often carries a musty smell and an unusual taste, caused by sediment buildup, rust, or biological contaminants. A periodical house water tank cleaning service keeps the water clear, fresh, and suitable for everyday household use.

Protection for your plumbing and appliances Keeping the water tank clean protects your plumbing and appliances from avoidable wear and tear, saving you money in the long run. A professional water tank cleaning service like ours can handle this for you.

Signs Your Water Tank Needs Cleaning

• Discoloured or cloudy water — a sign of sediment, rust, or contaminant buildup inside the tank
• Unpleasant smell or taste — musty, metallic, or stale water often points to bacteria or algae
• Reduced water flow — sediment can restrict flow through the tank and connected pipes
• Visible debris or insects — pests or particles inside the tank mean it’s overdue for a clean
• It’s been over a year — even without obvious signs, contaminants accumulate over time

Types of Water Tanks We Clean

House domestic water tanks For most households, domestic water tanks come in stainless steel, plastic (polyethylene), or fibre-reinforced plastic (FRP). Each material has its benefits, but all need periodical cleaning to prevent sediment buildup and bacterial growth. Our service ensures each type of tank is thoroughly washed and scrubbed.

Commercial water tanks For commercial concrete or cement water tanks, we use pressure washing, manual scrubbing, and chemical disinfection to remove years of accumulated grime. Our team is equipped to handle these large-scale cleanings efficiently, so businesses and tenants receive clean, reliable water.

Underground concrete tanks Out of sight, these tanks are often forgotten and left unchecked for a long time, making them prone to sludge buildup, foul odours, and pest infestations. Because of the limited visibility and access, cleaning them requires specialised tools and trained professionals. Our service includes draining the tank, removing sediment, disinfecting the interior walls, and inspecting for leaks or structural damage.

Our Water Tank Cleaning Process

Our process begins with an inspection of the tank to assess its condition. We then drain all the stored water to expose the interior. Once emptied, we remove the accumulated sediment and scrub the tank thoroughly. Finally, the tank is rinsed to remove any residual cleaning solution and refilled with clean water.

What Affects Your Water Tank Cleaning Quote

• Water tank size — larger tanks take more time, effort, workers, and materials to drain, scrub, and clean than smaller domestic tanks
• Type of water tank — stainless steel and plastic tanks are easier to clean, while FRP and concrete tanks may need more intensive scrubbing or specialised equipment
• Condition of the tank — a regularly maintained tank is quicker to clean than one full of grime, which needs extended cleaning time and more solution
• Your location — let us know your address so we can provide an accurate quote
• Accessibility — tanks on rooftops, in narrow shafts, or underground with limited entry points can take more effort to access

Regular water tank cleaning is key to the health, safety, and well-being of your household. Over time, even the cleanest-looking tanks can harbour harmful bacteria, algae, and sediment that compromise water quality and affect your plumbing.

Our professional water tank cleaners offer a reliable, thorough, and affordable solution tailored to different tank types and conditions.

How often should a house water tank be cleaned?

We recommend cleaning your house water tank at least once a year to maintain good water hygiene and quality. Annual cleaning helps prevent the buildup of dirt, bacteria, algae, and other contaminants that can damage your plumbing system.

How long does the water tank cleaning process take?

On average, the process takes about 3 to 5 hours, depending on the size and type of tank, the level of dirt or sludge buildup, and how accessible the tank is. Our team works efficiently to complete the job with minimal disruption while ensuring thorough cleaning and disinfection.

Can I clean my water tank myself?

Basic surface rinsing is possible, but a thorough clean means fully draining the tank, scrubbing the interior, and disinfecting it, often in a rooftop or underground space that’s hard to access safely. A professional service ensures the tank is properly cleaned and the water supply isn’t contaminated in the process.
