About WET Systems

WET Systems specialises in the development of sustainable, energy-efficient, ecological-oriented wastewater management solutions. Based in the Hunter Valley (NSW, Australia), we provide our services throughout the Australasia region and internationally. We have extensive in-house experience in the design of constructed wetlands and eco-technologies for the treatment of a full range of contaminated waters, including municipal sewage, on-site and decentralised wastewater, greywater, landfill leachate, industrial effluents, sewage sludge, wastewater from oil & gas and mining operations, agricultural wastes, nursery runoff and stormwater. We also develop solutions for sustainable reuse and management of treated effluent, plant nursery irrigation recycling systems and waterless sanitation.

With a solid scientific foundation in development of innovative, customised solutions, we pride ourselves on working closely with our clients and stakeholders to tackle the most challenging wastewaters, sites, remote locations and regulatory hurdles. We are also dedicated to applying our knowledge and experience for the application of appropriate sanitation and wastewater management systems for low-income communities and developing countries, where sustainable solutions are needed most.

WET Systems has extensive experience in wetland planting and vegetation management. We offer a range of on-site wastewater management systems for single households up to small communities, including advanced systems capable of high level nutrient removal for use in sensitive locations and catchments.

Above all, WET Systems is guided by the core values and principles of: upholding the highest levels of professional integrity; taking pride in our work; providing value-for-money and personalised service, collaborating closely with other like-minded people and organisations, and working with Mother Nature.


Working with other companies on joint projects allows us to provide our expertise where it is needed most, ensuring the design of our systems are of the highest standard.
