A Deep Dive into Australian Standards: Ensuring Quality in Water Storage Solutions

According to the Water Industry Operators Association of Australia, the disinfection of water (potable or recycled) with a chemical disinfectant (chlorine or chloramine) requires time for the chemical to react with and kill the target microbial pathogens. The effective contact time is often less than assumed.

Many water utilities use a target-free or total chlorine residual in their treatment systems to achieve a level of disinfection they understand to be adequate. This approach to disinfection can be improved in most cases.

Corrosion is a natural phenomenon governed by chemistry, metallurgy, and electricity. Energy added during the smelting and refining of iron ore causes an energy imbalance, leading to corrosion. Three elements must be present for corrosion: a metal, an electrolyte, and oxygen. Corrosion on the outside of water storage solutions varies greatly based on atmospheric conditions.

Many water utilities adopt a target-free or total chlorine residual strategy in their treatment systems to ensure what they believe to be an adequate level of disinfection. While this approach has been widely used, there is room for improvement in most cases. The effectiveness of chlorine-based disinfectants can be influenced by various factors, including water temperature, pH levels, and the presence of organic matter. It’s essential to consider these variables to optimize the disinfection process and enhance water safety.

To improve disinfection practices, water utilities should conduct thorough assessments of their treatment systems. This includes evaluating the distribution of disinfectants, monitoring water quality parameters, and understanding the specific characteristics of the water source. By identifying and addressing potential challenges, utilities can enhance the overall efficiency of their disinfection processes.

The interior and exterior corrosion of potable water storage solutions can be effectively controlled by using protective coatings and cathodic protection. Coatings are the accepted method for protecting the tank’s exterior, creating a barrier against chemical compounds and moisture.

Preventative Medicine


Coatings are essential for protecting the tank’s exterior, providing a barrier against chemical compounds and moisture. While an electrolyte is not always present in this area, water ingress prevention is critical. We offer tried and tested services in Sydney, Melbourne, Brisbane, Canberra, Dalby, Darwin, and Geelong.
