Construction supervision
Tonkin understands the importance of timeliness during this critical phase, and we are able to provide dedicated resources on site when required, as well as assistance with documentation of as-built infrastructure.

Treatment

Efficient and sustainable application of treatment solutions play a critical role in maintaining public health, environmental protection, and regulatory compliance. Tonkin has expertise across all stages of treatment – from selecting a site for a new desalination plant, to upgrading an existing regional wastewater treatment plant, we work closely with our clients to find innovative and fit-for-purpose solutions. Tonkin's experience spans across the treatment of drinking water and wastewater, as well as water reuse.

Drinking water
Turning on the tap to access safe, quality water is something we often take for granted. Tonkin is passionate about ensuring communities in metro and regional areas have the best possible access to reliable drinking water by designing fit-for-purpose treatment facilities.

Wastewater
Effective treatment of wastewater before it is released into the environment ensures the sustainability of rivers, lakes and oceans. Tonkin strives to achieve design outcomes that protect aquatic ecosystems, preserve biodiversity and maintains health environments.

Reuse
Urbanisation and demand for water is reshaping how we think of wastewater. Disposal of effluent is becoming the least preferred solution with reuse and resource recovery becoming more prevalent. We help our clients find effective ways to reuse treated wastewater so it can be reclaimed for irrigation, industrial processes, and cooling, reducing demand on freshwater resources.
