Wastewater System Design

Our extensive experience and familiaraity with ALL locally available wasterwater treatment systems enables us to provide you with the most cost effective solution to suit your requirements.

We are not affliatied with any supplier or manufacturer.
We provide a truly independent design service.

Our designs have saved our clients many $1000’s of dollars. We cover all levels of wastewater  treatment system design including:

  • primary treatment( including septic systems)
  • secondary treatment
  • advanced secondary treatment

An appropriatre solution isn’t always the most expensive – we have designed solutions for clients using advanced septic systems which are appropriate for council requirements and save the customer money compared with other systems.

We design for all project sizes

Herberton Hospital
Large capacity

This project involved an upgrade from traditional septic system. The treatment upgrade has transformed a septic quagmire into a highly successful system that integrates sub-surface irrigation as parts of its design.

Kuranda Steiner School
Medium Capacity

A projected increase in usage meant that the existing septic system need to be upgraded. A passive advanced secondary system was recommended and installed.

 Redlynch Valley
Residential capacity

This site was adjacent to Freshwater Creek, requiring a high standard of treatment to protect this pristine water course. We designed an advanced septic treatment system as an alternative to a more expensive secondary treatment option. This was a significant cost saving both in the intial installation and ongoing maintenance.
