During heavy rain, storm tanks are utilized to store excess water from the sewage system. This helps prevent sewage treatment plants from becoming overloaded. Once the contaminated water is stored in the tanks, it is released back into the sewage system when it can be managed more effectively. This prevents the water treatment systems in cities from becoming overwhelmed and overflowing during rainy periods. However, the water stored in these tanks contains a large number of organic and inorganic contaminants. As the water may remain in the tanks for several days, significant sedimentation occurs. Due to the presence of organic substances, bacterial activity can lead to the formation of putrid and toxic residues. These residues pose serious health and contamination risks if left unattended, and can ultimately hinder the effective operation of the storm tanks.


Impingement cleaning is a common method for cleaning storm tanks, where an eductor system creates a swirl as the tank empties to remove buildup and debris. However, this method may not always provide a thorough clean, especially when it comes to removing toxic deposits. Fortunately, the Storm Blaster impingement cleaning system offers an effective solution for tackling even the toughest deposits.
One example of the Storm Blaster in action is the Synergy spray Tank cleaner, which was recently installed in a Victorian storm tank. This powerful impingement cleaning system uses a sweeping plane that cuts below the horizontal line to ensure a complete clean while protecting the surrounding framework. Over time, the sweeping plane covers every inch of the tank, removing all debris and buildup for a thorough clean.


High-powered cleaning is necessary for storm overflow tanks, and the most suitable systems for such applications are our rotating tank cleaners. However, we have made several modifications to the standard design to better meet the needs of our water utility clients.


To optimize storm tank cleaning, the design of the Orbitor has been modified to create a faster and less precise cleaning pattern. While the Orbitor is capable of developing an accurate spray pattern over time for other applications, a precise spray pattern is not strictly necessary for non-sterile storm drain cleaning. Instead, a quick and powerful wash cycle is required to remove debris and buildup while minimizing water usage.


Any storm tank cleaning system must be designed to withstand harsh conditions and be adaptable to different situations. The cleaning heads may become clogged and require self-cleaning mechanisms. The equipment must also be able to operate in varying temperatures and withstand potential wear and tear. Given that storm tanks are often located in confined spaces, it is essential to have a maintenance-friendly system that is easy to repair.
The primary objective of an automated storm tank cleaning system is to reduce labor time, so having a complex and cumbersome cleaning process would be counterproductive. Our storm tank cleaners are designed with durable materials to prevent breakage and feature a self-cleaning mechanism to prevent deposits from building up on the equipment. Additionally, our cleaners are fully operational even after being submerged in water, making them ideal for tough storm tank cleaning jobs.
