WGA has a strong focus on integrated water management, with integral roles in the design and development of over 50 stormwater and wastewater reuse schemes. 

Our involvement frequently spans all project phases; from feasibility assessments, business case analysis, funding submissions, design, approvals, construction surveillance and project management, through to commissioning and operational monitoring. WGA has significant expertise in the development, design and construction of Community Wastewater Management Systems (CWMS) incorporating reuse of treated effluent; integrating system-wide collection networks; treatment systems, and distribution schemes. We are leaders in the design of innovative water sensitive urban design (WSUD) strategies, with experience across many award-winning commercial, educational and community facilities utilising our flood modelling and Integrated Water Cycle Management plans.

In 2016, hydrogeological specialists Aqueon merged with WGA after a long association partnering in the delivery of numerous reuse water supply and management projects both in South Australia and nationally. This has strengthened our ability to provide quality hydrogeological and engineering solutions for water supply management to industry, agriculture, government and the mining and petroleum sectors.
