The Whyalla City Council is putting together a stormwater management plan (SMP) and wants community input.
A SMP is a strategic planning document that aims to address existing stormwater problems within a catchment, or catchments.
It identifies opportunities for providing a range of benefits through a multi-objective planning process. This multi-objective planning includes consideration of flood risk, protection of water quality and opportunities for stormwater reuse.
There have been numerous occurrences of flooding within Whyalla, including those in November 2015 and September 2016.
While heavy downpours have historically resulted in nuisance flooding within the city, there had been no detailed assessment of the flooding risk posed by varying rainfall events to clearly document the extent and severity of problem areas.
In response to this, Council, with financial support from the State and Federal Governments, has commissioned Tonkin Consulting to develop a Stormwater Management Plan for the City of Whyalla.
The document provides a clear understanding of the current issues and will enable Council to develop a consistent, sustainable, environmentally aware and integrated approach to stormwater management.
The plan will provide a framework to address priority drainage issues, integrate future development, land use and infrastructure planning across the city.
While largely driven by the need to address stormwater flooding within the city, Council are also keen to explore opportunities for integrated water management, including addressing the quality of water discharging to Spencer Gulf and potential reuse to augment Council’s existing non-potable irrigation scheme.
Feedback on the draft SMP can be provided (until March 28) via the following:
