Step 2

Creating your project design

We provide an initial design to assist you with more clarification on your project. This includes the correct flow rates, to ensure you have the correct size system, and to ensure that your budget is taken into account. Once you are happy, we provide full hydraulic engineered drawings, necessary paper work to assist with all Tradewaste and Council approvals.

Step 3

Manufacturing and delivery

We begin building your wastewater treatment system. All our equipment comes professionally packed and transported to your allocated destination.

Step 4


Once we arrive on site, we commence installing the system using qualified trained staff. We test and commission the entire system. We then train your staff on the system running procedure, maintenance and breakdown sourcing. Ensure your running costs are minimal.

What to do with your wastewater

  • Features of oil water separators and installed prior to discharge, to treat the wash down bay water.
  • Discharging to sewer is commonly used, check your local trade waste guidelines.
  • If discharge to the Environment is necessary. An upgrade to an EPA compliant system will be designed. This requires much better filtration and higher grade discharge levels.
  • If you wash down area is not or unable to be roofed, a first flush diversion system to divert rainwater to be installed.
  • Enter into a maintenance agreement for servicing of your water treatment equipment in accordance with Council or EPA regulations. This is a detailed process by a licensed technician. Not just pumped out. Which is not classed as a service.
  • Only use biodegradable quick break degreases and detergents. This assists with Hydrocarbon separation prior to the oil separator treatment.
  • Use only helical rotor (i.e. Mono) or diaphragm pumps to pump waste water to the oil separator. Submersible pumps etc will cause emulsification. Which is binding the oil and water together. This is extremely difficult to reverse, without the use of costly equipment.

What not to do with your wastewater

  • Do not use traditional solvent based degreases that do not have quick break properties. These degrease cause oil and detergents to remain in suspension and not separate through a traditional oil water separator system.
  • Do not dispose of any coolants, acids, caustics or chemicals through the water treatment system, these should be disposed of by licensed contractors.
  • Do not allow wash down water to discharge directly to the storm water drain/environment.
  • Not allow storm water to enter the wash bay bunded area.
  • Not allow workshops or other areas discharge water to your water treatment system area.
  • Do not adjust or modify any treatment equipment without prior approval from the manufacturer.
