From a presentation by Jim Townsend, CEO Suburban Water, “Remote Storm Water Management”

Suburban Water was established to actively test and develop storm water harvesting technology in Australian suburbs. The premise of the project is that captured storm water doesn’t need to be treated to potable levels – between 30 -35% of current urban water use could be directly replaced with storm water.

As the recipient of a Round 3 grant from the Smart Water Fund, the company was able to install a pilot harvesting system in the city of Kingston, Victoria. Using the local aquifer, telemetry and a combination of existing and new infrastructure, the system allows water to be captured and shared between two separate sites, and increases each site’s ability to prepare for and capture heavy rain.

The System:
Storm water captured at Southern Road Reserve is fed into concrete tanks, where it is treated and returned to the aquifer as part of a managed aquifer recharge system.  It is held there until needed either at Southern Road Reserve or at Parkdale Secondary College, just over a kilometre away. Parkdale Secondary College captures its own storm water and stores it in rainwater tanks, which provide toilet flush water and irrigation for the grounds. When these tanks are nearly half-empty, a monitor alerts the remote control at Suburban Water in Adelaide. The subterranean tanks at Southern Road Reserve pump water up into the existing Melbourne Water drain, and the water arrives to be treated and pumped into the school’s tanks 90 minutes later.
When significant rainfall is expected, the tanks at Southern Road Reserve empty into the aquifer in order to capture as much new rainfall as possible.

Key Outcomes:
The project is well into its prototype and testing stage, and while there have been significant challenges, CEO Jim Townsend emphasised the importance of being able to put a price on storm water capture and reuse – excluding the cost of installation but including regular running costs such as pumping and monitoring, the price is approximately $0.4/kL.

Stormwater Storage Aquifer: Rossdale Golf Club

The Smart Water Fund congratulates Rossdale Golf Club on being announced as a finalist for the inaugural Prime Minister’s Water Wise Award.  One of five national finalists, Rossdale Golf Club was nominated for its integrated stormwater harvesting and aquifer storage and recovery project. Working in partnership with the CSIRO, the Club received funding from the Smart Water Fund to implement Victoria’s first aquifer storage and recovery project (ASR).  The project has seen the Club reduce its drinking water usage by 56 per cent, saving 35 million litres per year while still providing a high quality course for local golfers.  This innovative approach to water management combines the harvesting of stormwater from a nearby drain with traditional dam storage and the innovative ASR process.  ASR is the process of using natural underground aquifers as storage medium for treated urban stormwater that can then be used as required.

In Rossdale Golf Club’s case, stormwater collected during the winter months is stored within an aquifer until needed during the dry summer period.

Smart Water Fund CEO Christine Cussen congratulates Rossdale Golf Club on being recognised by this prestigious award.  “To be nominated as a finalist for the Prime Minister’s Water Wise Award is a fantastic achievement for the Rossdale Golf Club and for the CSIRO research team, backed by the Smart Water Fund, who has contributed to the success of this project,” she said.  “This project is a great example of research being applied to create real life water saving solutions.  With such positive results, the lessons learnt by Rossdale Golf Club are already being leveraged by other golf clubs and local councils across Victoria who are investigating the potential of ASR,” Ms Cussen said.
