At The Watertank Cleaning Company SA, based in Victor Harbor, we provide professional water tank cleaning services across the Fleurieu Peninsula and surrounding regional areas. Our goal is simple – to keep your water clean, safe, and fresh so your family, livestock, or business can rely on a healthy water supply. As a locally owned and family-run business under new management, we’re proud to combine quality workmanship with a community-first approach.
We understand how vital clean water is in South Australia, where many properties depend on rainwater tanks. Over time, sediment, leaves, sludge, and bacteria can build up inside your tank, affecting water quality and health. That’s why we use specialised industrial equipment to thoroughly clean and sanitise your tank with minimal water loss.
Whether you need a one-off clean or regular maintenance, our professional team is here to provide reliable service tailored to your tank type and needs.
Water Tank Cleaning for All Tank Types—Any Size
No two water tanks are the same, which is why we provide cleaning solutions for all sizes and materials. From small poly tanks on suburban homes to large concrete tanks on farms, we’ve got the equipment and expertise to handle it all. Whatever your system, we’ll ensure your tank is left clean, fresh, and ready to use.
Concrete Water Tank Cleaning
Concrete tanks often accumulate sludge and bacteria over time. Our vacuum process ensures a thorough clean while protecting the structural integrity of your tank.
Poly Water Tank Cleaning
Poly tanks are common for homes and small businesses. We carefully remove debris and sediment to restore safe, fresh water for your property.
Galvanised Tank Cleaning
Galvanised tanks can be prone to rust and residue. Our cleaning process helps extend the life of your tank while ensuring water remains clear.
Lined Tank Cleaning
Lined tanks require gentle but effective cleaning. We adapt our methods to avoid damage while removing sludge and improving water quality.
Who We Provide Water Tank Cleaning Services For
Farms and Agricultural Properties
Clean water is essential for livestock, crops, and equipment. We make sure your farm tanks are well maintained so your business can keep running smoothly.
Homes and Urban Properties
For households, safe water is non-negotiable. Our cleaning service ensures your family always has fresh, healthy water on hand.
Our Professional Tank Cleaning Process
Every tank is different, which is why we take the time to assess your tank type, size, and condition before we begin. This allows us to give an accurate quote and choose the best cleaning method for the job. Our process is thorough, reliable, and designed to protect your water supply.
We use specialised vacuum systems that remove sludge from the base of the tank without draining all the water. If the water is badly contaminated, we may recommend draining before cleaning. Either way, our team will leave your tank spotless and ready to be filled with clean, safe water again.
Water Sanitising Services
In addition to cleaning, we also offer water sanitising. If your water smells, tastes unusual, or looks cloudy, bacteria may be present. We use clean oxide to restore water quality quickly and safely.
If contamination is severe, we may recommend draining the tank first before applying treatment. This ensures your water is left safe, fresh, and free from harmful bacteria.
Why Regular Tank Cleaning Is Important
Keeping your tank clean is not just about taste—it’s about protecting your health and your investment. Dirty tanks can Harbor bacteria that make water unsafe for drinking, cooking, or washing. A buildup of sludge can also damage pumps, block filters, and reduce the lifespan of your water system.
By scheduling regular cleaning, you’ll ensure a safe water supply for your family, reduce the risk of breakdowns, and avoid costly repairs or replacements in the future. It’s a simple step that makes a big difference.
Frequently Asked Questions
Will I lose water in the cleaning process?
No, our vacuum system is designed to minimise water loss while removing sludge and debris.
Does the tank need to be empty before cleaning?
No. In fact, the cleaning process works best when the tank is full.
How often should I get my tank cleaned?
SA Health recommends checking every 2–3 years, depending on your gutters and water use. If there’s sludge or bacteria present, it’s time for a clean.
Can you remove bad smells or tastes from my water?
Yes. If your water tastes or smells unpleasant, we can use clean oxide treatments to sanitise and restore water quality.
Do you inspect tanks for damage while cleaning?
Yes, we always check your tank during cleaning. If we find cracks or leaks, we can recommend repairs before the issue worsens.
