By understanding the combined sourcing, treatment and delivery
costs, SA Water can develop optimal operating plans and identify
areas of improvement in the supply chain.
As a result of the Decision Support Tools, SA Water can quickly
answer the following questions:
Where are costs being incurred now?
How will different operating arrangements influence costs?
How will disruptive capital works projects affect operating costs?
With the move to spot pricing in the electricity market, tools like
the EPM Dashboard give SA Water a clear picture of forecast
electricity prices. This allows SA Water to schedule major
pumping to take advantage of short-term price reductions,
and integrate electricity price forecasting directly into the
optimisation tools. Electricity price forecasting information
influences control-room decision-making, and results in major
savings in pumping costs.
Charles Sturt’s Water Proofing the West – Stage
The City of Charles Sturt, together with the South Australian and
federal governments, has officially completed and opened the Water
Proofing the West – Stage One Project. The Project is unique;
it is an integrated water sensitive urban design solution to the
challenges associated with stormwater management, stormwater
quality improvement, flood management and water supply
management in a fully developed urban environment.
Water Proofing the West (WPW) was a major initiative by the
City of Charles Sturt, with combined expenditure of $71.5 million.
The Project was a collaborative funding project with nine funding
partners, and contributors from all three levels of government, as
well as the St Clair Joint Venture (UPL Pty Ltd and AVJennings)
and the West Lakes Golf Club. The St Clair subdivision was a
$20.2-million component within WPW, and was operated as a
collaborative project through the design and development stages
with a Project Steering Group, which included members from the
St Clair JV, Renewal SA and the City of Charles Sturt.
To design and construct the works, the council worked with South
Australian businesses including Aurecon (project management)
Wallbridge & Gilbert (lead design consultants), DesignFlow (wetland
concept designers) and Australian Groundwater Technologies
(aquifer expertise). Additional South Australian businesses for
wetlands and managed aquifer recharge construction expertise
included Olympic Boring, Guidera O’Connor, LogiCamms, SADB
Directional Drilling, Leed Engineering and Construction, and
Landscape Construction Services. The Project is a leading example
of the range of skills and water expertise in South Australia.
Stormwater management and flood mitigation has been one of
the most significant issues facing the City of Charles Sturt. Many
suburbs in the City have a long history of flooding because the land
is so flat and close to sea level. In addition to flood risk, the drought
conditions, commencing in 2003 with Level 3 water restrictions, saw
many Council reserves and natural vegetation areas deteriorate, with
many displaying extreme stress. There has been growing community
concern that significant trees are dying, and that many of Council’s
shrubs and reserves have browned off and are dying.
From these two Council drivers, a vision developed that sought to
reduce flood risk while also providing more sustainable water use.
Charles Sturt’s vision for the WPW Project was to create the first
stage of a region-wide system that harvests, treats and stores water
underground in rock aquifers, and then later distributes the recycled
water through sections of western Adelaide, sustaining a growing
economy and enhancing the natural environment.
Water harvesting was also enhanced with the capture of excess River
Torrens water, which would otherwise be discharged to sea. The
Project developed infrastructure capable of capturing and treating up
to 2400 million litres of water, and this will supply recycled stormwater
annually to replace current and future potable water demands, and
to protect and sustain the groundwater resources in the City of
Charles Sturt area. It will supply recycled water, primarily for irrigation
purposes for domestic and industrial demands. Water assets were
created across five linked sites and two stormwater catchment
areas, with 11 hectares of wetlands, 15 bores into the rock aquifers
and 36 kilometres of distribution mains to supply recycled water to
reserves, schools and as a third-pipe water system in new residential
developments at St Clair and Woodville West.
