    Strategic planning and advanced modelling of stormwater, wastewater and drinking water projects

    Over the past few years, the Government has been considering how New Zealand's three water services (drinking water, wastewater and stormwater) should best be regulated and delivered. Currently, 67 local councils own and operate their individual water services. However, the Government believes comprehensive, system-wide reform is needed to achieve lasting benefits for communities and the environment.

    Fluent Solutions is proudly Dunedin District Council's preferred civil engineering firm for 3 waters consultation, planning and design. We have worked on numerous regional stormwater, wastewater and drinking water projects, ensuring accurate assessment and innovative engineering design solutions. Our progressive team prioritise sustainability by undertaking extensive environmental impact assessments before commencing any new water or infrastructure projects.
