The Morphettville Racecourse Wetland was a joint initiative of the
Patawalonga Catchment Water Management Board and the
South Australian Jockey Club. It was constructed by the Board and the Jockey Club during 2001 and 2002. The wetland covers an area of in the middle of the racecourse on the corner of Anzac Highway and Morphett Road. Costing $2.4 million to construct, it includes 100,000 plants. The soil excavated was used to raise the level of the racecourse track. The catchment area for the wetland includes
stormwater flow from two drains in Bray Street, south of the racecourse. Water enters a sediment pond where floating litter is collected in a net and large materials settle out. The water is then piped into the wetland, where it travels through a series of deep and shallow marshes. An
aquifer storage and recovery system has been constructed at the wetland. The water flowing out of the wetland is ideal for
irrigation as it has very low
salinity. During winter months, water is captured and pumped into a tertiary
limestone aquifer below the racecourse. During the summer months, the water in the aquifer is recovered and used for irrigation. Up to 600 megalitres of water a year is recharged into the aquifer, which exceeds the amount required to irrigate the racecourse. ==Access==
