The City of Greater Dandenong’s drainage network comprises some 18 urban catchments covering an area of approximately 129,000 hectares. This drainage network forms part of the overall Melbourne Metropolitan Stormwater System draining into the Lower Dandenong Creek Waterway to the south, eventually discharging into Port Phillip Bay.

The City of Greater Dandenong is currently responsible for the management, operation and maintenance of approximately 800 km of underground drains ranging in size from 150mm diameter to 2,100mm diameter, 80 km of open drains, 5 retarding basins and 3 pump stations, some 27,000 drainage pits and litter traps. The current replacement value of the drainage network is estimated at approximately $133 million.

The Storm Water Strategy deals with issues relating to storm water management within the City of Greater Dandenong and makes recommendations that enable the council to put policies in place and implement actions to manage storm water effectively and efficiently. Currently, Council is undertaking catchment studies to determine overland stormwater flow paths for the city and to formulate flood mitigation options. This work is being undertaken in close collaboration with Melbourne Water.

Stormwater quality has also been recognised for many years as a significant contributor of pollution to our waterways resulting in reduced environmental value and public amenity. The City of Greater Dandenong has put into place action plans to minimise the pollution of our waterways and to implement environmentally friendly stormwater design options.
