The City of Norwood, Payneham and St Peters is a metropolitan council, covering an area of 15.1 square Kilometres, east of Adelaide’s CBD. One of the primary services that the council provides for the 34,000 residents is the storm water drainage network. The drainage network allows for the effective collection of surface water in the area and provides flood protection throughout the city. The majority of the system comprises of storm water pipes, pits, junction boxes and culverts, the storm water makes its way to First Creek, the River Torrens and ultimately Gulf St Vincent.
