Stormwater and flood mitigation project progresses as City of NPSP secures nationally recognised civil contractor
A $20 million stormwater and flood mitigation project is one step closer to being completed, following a decision by the City of Norwood Payneham & St Peters to lock in a nationally recognised civil contractor.
Elected Members unanimously endorsed the appointment of civil contactor BMD to undertake Stages 2 and 3 of the Trinity Valley Stormwater Upgrade – one of the biggest flood mitigation projects in the Council’s history.
Mayor Robert Bria said the Council was extremely grateful for the $9.9 million it had received from the Australian Government’s Preparing Australian Communities Program, which targets local projects across the nation, with a focus on improving resilience against natural disasters.
“This funding has been matched by the Council, making it one of the biggest investments in the Council’s history to date.
“The new infrastructure will reduce surface flood waters during storm events by capturing stormwater and temporarily storing it in a proposed detention basin and underground detention tanks within the road network,” Mayor Bria said.
The upgrade to the City’s stormwater drainage network is taking place in the suburbs of St Morris, Trinity Gardens, Maylands and Stepney (known as the Trinity Valley).
The Trinity Valley Drainage Upgrade involves the installation of a new underground stormwater management network to increase capacity and once completed will result in improved flood mitigation during significant rainfall events.
There are four stages in total with Stages 2 and 3 to commence with major works to get underway in October 2023 and completed by May 2024, with work involving the installation of small and large underground culverts, pipes, drainage pits and, where required, reconstruction of roads.
