Frequently Asked Questions

The primary factor influencing cost is the size of the tank. Unlike other companies, we don’t conduct unnecessary inspections or use a sliding scale based on sludge levels. Simply tell us the size, and we’ll provide a transparent quote, regardless of your location within the state.

At the Water Tank Cleaning Company, our comprehensive tank cleaning process ensures your water is safe and clean:

We use specialised equipment to vacuum out all sediment, sludge, and debris from your tank. This includes removing buildup from the bottom, sides, and any hard-to-reach areas. We take extra care to ensure complete removal, leaving your tank sparkling clean.

For a personalised quote, please contact us and provide details about your specific water tank setup. We’ll be happy to assess your needs and provide an accurate estimate.

Generally, yes. However, very small (500 liters) or extremely large tanks can pose challenges due to manhole size or accessibility. We can clean tanks up to approximately 130,000 liters and potentially larger, depending on specific requirements. Feel free to call us to discuss your situation.

We believe in reminding our customers every five years, but we understand some prefer more frequent cleaning. So, yes, we can tailor a maintenance plan to your specific needs.

We use a vacuum system to remove loose debris from the tank floor. This process typically results in losing about one foot of water for every ten years the tank has been uncleaned. We don’t remove, filter, and replace all the water, as that would require an impractical amount of resources. 

The duration depends on factors like the number of tanks, their location, and accessibility. For a couple of easily accessible tanks, we usually complete the process within two hours.

Not at all. In fact, it will improve your water supply by removing contaminants and sediment.

Yes, we can provide documentation of the service, detailing the cleaning process and any findings, if required.

You don’t need to do much. Clearing the area around the manhole is helpful, but not essential. The most important requirement is that the tank contains water. We cannot effectively clean an empty or near-empty tank. Having 2-3 feet of water is a good minimum for a thorough cleaning.

Absolutely! We don’t introduce any chemicals into your tank. Our process focuses on removing contaminants. In cases of severely compromised water, we offer a Puretec product for treatment, which you can also purchase and apply yourself. Be cautious of companies claiming to have “special” products at exorbitant prices. Any introduced product will only remain active for a limited time, and the water will eventually revert to its natural state unless regularly treated. The best approach is to remove sludge, maintain clean gutters, and monitor the tank regularly.

We can clean underground tanks and tanks on stands up to approximately 8 feet high. For tanks requiring specialized equipment or access methods, the client would be responsible for those additional costs. We always assess each situation and aim for the most cost-effective and least disruptive solution for our clients.

The quality of the water coming out of the tank will match the quality of the water going in. However, keep in mind that a clean tank can only do so much. If you allow contaminated water to enter the tank, the water coming out can still be compromised.

While water tanks can be cleaned anytime if there are specific issues like dead animals, debris build up, or suspected contamination, we generally recommend scheduling a cleaning before the spring or summer months.

Warmer temperatures create an ideal environment for bacteria to multiply, so proactively cleaning your tank beforehand can help prevent potential health issues and ensure your water stays fresh and safe throughout the warmer seasons.

Several factors influence cleaning frequency: the number of downpipes, surrounding environment (e.g., overhanging trees), and gutter protection systems. Generally, tanks with at least one downpipe accumulate significant sludge within five years. Government guidelines recommend checking for sludge every 2-3 years. Don’t be fooled by suggestions of yearly cleaning!

Several signs indicate a need for cleaning: unusual smells, tastes, or discoloration of the water; frequent filter blockages or replacements; and noticing an odor, especially in hot water (e.g., during showers). If it’s been several years since your last cleaning or if you’ve recently moved into a new home, it’s safe to assume your tank is due for a cleaning.

Regular potable water tank cleaning minimizes bacteria growth by removing sludge, their primary habitat. This improves water filter effectiveness, extends pump lifespan, and enhances water pressure. Clean water tanks equal healthier water and better-functioning systems.

Uncleaned potable water tanks can develop unpleasant smells, tastes, and discoloration. More serious risks include illness and, in extreme cases, pump failure due to excessive sediment buildup.

Yes, you can. The purpose of the cleaning process is to ensure the water remains safe for consumption.

If you supply potable water to the community (e.g., school, winery, B&B, or community hall), it’s crucial to adhere to guidelines for regular gutter cleaning and tank desludging. If someone were to become ill from the water, the question would be whether you followed the recommended minimum maintenance practices.

We have experience removing various contaminants from tanks, including animals and chemicals. If a tank is severely contaminated, we can safely drain it and follow confined space protocols to clean it thoroughly. We always explore all options before deciding on a course of action, prioritizing the most cost-effective and least disruptive solution for the client.
