Keeping wastewater treatment plants operating

As Australia’s population increases so does the reliance on wastewater treatment. The role of treatment plants is becoming more important in treating wastewater and producing recycled water, biosolids and biogas. These processes can be disrupted by corroding and deteriorating assets causing lengthy downtime and maintenance. To keep wastewater treatment plants operating efficiently it’s important to [...]

Sealing infrastructure for a sustainable future

Sustainable infrastructure refers to the design, build and operation of assets to reduce negative impacts on social, economic and ecological processes. This is applicable to new and aging infrastructure to meet the demands of growing populations and to withstand the test of time. Applying coatings to infrastructure such as bridges, walkways, roads, and water and [...]

Preventing degradation of reinforced concrete water structures

Reinforced concrete is commonly used for construction in the water industry due to its high durability and ability to sustain stress from vibrations, winds and external forces. However, if left unprotected, chemical and physical influences can cause severe degradation. The key to extending the life of reinforced concrete water assets is installing an appropriate protective [...]

Protecting concrete with cementitious waterproofing slurries

Concrete is the most commonly used material in the construction industry. However, while it is durable, it is not unfailing, and if exposed to water, it can weaken over time. This is because concrete is porous, so water and other fluids can easily infiltrate the surface. To prevent this, and increase the longevity and durability [...]

Potable water coating up to standard

Without an appropriate protective coating, water infrastructure can be subject to corrosion, rust and bacteria which can affect the longevity of the asset as well as  water quality. When coating potable water assets, it is important to select a coating that meets the requirements outlined in Australian Standard AS4020 regarding material that comes into contact [...]

Keeping corrosion at bay in the water industry

Water and wastewater infrastructure each have their own unique characteristics and requirements that need to be considered and adhered to when selecting a protective coating solution. Wastewater infrastructure is easily corroded from constant exposure to harsh chemicals and high levels of acidity, whereas water infrastructure is exposed to fewer chemicals but, as transport for a [...]

Transforming deteriorated wastewater assets

Wastewater infrastructure is exposed to a number of harsh chemicals and bacteria that cause erosion and deterioration. If left unprotected, assets such as manholes or sewers can threaten the integrity of an entire system while being costly to replace or rehabilitate. Using an appropriate protective coating can extend the life of an asset and reduce [...]

Geopolymer: the culvert operative

Culverts, like other water infrastructure, is aging and deteriorating at an increasing rate in Australia, and asset owners face the task of needing to rehabilitate or rebuild these assets before they become a serious danger to the public. While rebuilding culverts is a costly, time consuming and potentially disruptive task, geopolymer provides a solution for [...]

Rehabilitating a Gippsland water icon

The $250 million Gippsland Water Factory was built in 2010 and comprises two wastewater treatment plants sharing common infrastructure. A major part of the facility is the concrete structure that houses the membrane bioreactor (MBR), which plays a key role in the wastewater treatment process. These cells were originally lined with an epoxy, however, the [...]
