The Brown Hill and Keswick Creek Stormwater Project is an initiative of the Cities of Adelaide, Burnside, Mitcham, Unley and West Torrens, and aims to implement a stormwater management plan that will reduce the flood risk from Brown Hill and Keswick Creeks. One of the elements of the overall plan is flood storage in the South Parklands and Glenside. In addition to providing temporary flood storage, the project will deliver multiple outcomes including construction of wetlands in Victoria Park, water quality improvements, opportunities to harvest stormwater, increased flora and fauna habitats, and the creation of an amenity for users of the park.
Tonkin Consulting was engaged to undertake a Feasibility Study and subsequently to develop concept designs for the project, and has worked with a number of subconsultants, including a landscape architect, to develop the proposals.
The project has included a number of technical studies including floodplain mapping, water quality modelling, investigations into contamination status of soils, water harvesting and reuse, aquifer storage and reuse, and heritage considerations. Consultation has been undertaken with a range of organisations and stakeholders.
