Wastewater Treatment



Wastewater refers to the water used in residential, businesses, and institutional buildings which is flushed down the drains inside. It is 99% water, but is contaminated with toxic particles from human usage including cleaning chemicals, detergents, toilet solids, and more.

Once treated, wastewater can be either returned into the environment to continue the water cycle, or reused in applications such as irrigation and firefighting. This depends on the type of treatment and filtration which it undergoes.

There are three stages of wastewater treatment:

  • Primary: removes all large solids such as food scraps, wet wipes, etc. Grit tanks or sedimentation tanks are used to separate the unwanted material within the tank, where it is then scraped away.
  • Secondary: Microorganisms are added to the water to break down smaller particles such as nutrients and small organic solids. The ‘sludge’ that has so far been removed is turned into biosolids, whilst the treated water flows through to….
  • Tertiary: The water is filtered, then disinfected with UV light or chlorine depending on its intended distribution. This removes all remaining microorganisms.

Wastewater includes water that is used in residential homes, schools, business establishments, industrial buildings and more.

From sinks to toilets to drains, the water collected from these sources are contaminated with nutrients, bacteria, organic matter, cleaning products and trade waste, which can be detrimental to the environment and animals (including humans) alike if left untreated.

Wastewater is collected and processed through established facilities and piping networks throughout Greater Sydney for a minimised impact on our waterways, ensuring the safety of the public and the health of our ecosystems.


Water management concerns the control and movement of water resources, both to minimize damage to associated ecosystems, and to optimize its use. The purpose of this can vary, from manufacturing, to irrigation, to general population usage. In short, it’s about ensuring quantity, and quality.

With increased concerns regarding water as a resource, water management is becoming critical. We strive to provide high quality products and systems which serve the water management industry in this mission.


The chemical industry is incredibly diverse and complex, even in defining its scope: in summary, it’s concerned with the manufacture of solid, liquid, and gaseous materials. It involves the use of unique processes, such as chemical reactions and refinement methods, to create these materials which are usually used in manufacturing or industrial applications.

Chemical processes require specialised and high quality equipment which can handle the harsh and corrosive substances involved.

Simply put, the industry encompasses processes which utilise or generate both inorganic and organic materials, including petrochemical, agrochemicals, polymers, oleochemicals, rubber, polymers and more.
