Filtrex STS - SECONDARY Treatment System

The complete range of Filtrex Secondary Treatment Systems are specifically designed for environmentally sensitive areas in Western Australia.

These area’s where reticulated sewerage is not available include:

  • Water Catchment Areas

  • Nutrient Phosphate Retentive Sites

  • High Ground Water

  • Unfavourable Soil Condition’s requiring a more specialised system

  • Sewerage Sensitive Areas

  • Public Drinking Water Resource Areas

  • Wetlands

Filtrex is a Western Australian owned and operated company. We design, manufacture and install our own systems. Our Filtrex Secondary Treatment System gives us the ability to custom design a treatment system for your domestic and commercial needs.

When looking for a suitable system for your individual requirements, it becomes very confusing understanding the suitability of systems offered in the market place, making it difficult for the consumer to understand and define what is suitable and acceptable for their property. We have trained staff whom offer their knowledge and can liaise with your local government health department to ensure your onsite wastewater needs comply with the relevant regulations, be it for domestic or commercial applications.

Advantages of the Filtrex range:

  • No Service Agreements or Maintenance Contracts

  • No Chemicals/Additives

  • Subsurface treatment eliminating human contact, therefore creating a safer environment

  • Designs Suited to Residential and Commercial

  • Used by Institutional and Government Departments

  • Over 50 years experience
