FILE C:\DOCUMENTS AND SETTINGS\SLEES\LOCAL SETTINGS\TEMPORARY INTERNET FILES\OLK57\FINAL REPORT (REV 1).DOC ⏐ 19/01/06⏐ REVISION 1 ⏐ PAGE iii Drought-proofing Racing Racing Victoria Limited Final Report Executive Summary Racing Victoria Limited (RVL) is the peak body of the Victorian thoroughbred racing industry. As a result of the extended drought conditions in Victoria and the subsequent application of water restrictions, the thoroughbred racing industry in Victoria is at risk of not receiving adequate water supply to ensure the continued well being of the industry. As an initial step in addressing the risks involved, RVL was awarded a grant of $100,000 from the Smart Water Fund to undertake investigations of alternative water supply and improving water management for eleven racing venues around Melbourne. RVL appointed Connell Wagner to undertake investigations to identify water conservation measures and alternative viable water sources that will enhance drought proofing of the various racing venues. At present, the courses use around 860Ml of water per year, of which up to 650Ml is taken from the public water supply. Over 70% of the overall water demand is for irrigation of the courses, with the remainder being used for domestic appliances, racehorse facilities or irrigation of gardens. This study has demonstrated that if water from the domestic supply currently used for irrigation is replaced with an alternative supply, then up to 450Ml per year could be saved. If domestic appliances are replaced with more water efficient variants, then a further 28Ml/year can be saved from the public water supply demand. Overall this would be enough water to serve a population of over 8,000 people for a year. In some cases, the sites already have a secure supply and are not reliant on the public water system for anything other than domestic requirements. In others, plans are already well advanced to reduce reliance on the public supply, whilst at the same time ensuring security for drought periods. This study recommends that all courses except Sandown and Healesville produce plans for implementation of drought-proofing schemes. For the thoroughbred racing industry to decide how to invest in these courses, the priorities indicated in Table ES1 below should be used as a guide. This table has been produced to take into account that the cost of potable water is very low in Victoria. This means that there is little direct cost saving in replacing this source with an alternative (a process that can be very expensive). There are a number of incidental factors that need to be taken into account if the thoroughbred racing industry is not to be adversely affected by the continued water stress caused by the prolonged drought, however. These include financial loss due to closure, the public impact of a closure and its effect on the industry, and overall impact on the industry of the general loss of facilities. It is also recommended that the proposals for Cranbourne Training Centre and Cranbourne Racecourse are promoted as a demonstration project for the use of site drainage and treated effluent for irrigation needs. For all courses it is recommended that an audit of domestic and sanitary appliances be undertaken. This will enable the range of facilities to be recorded, their type, age and likely replacement date, which in turn will assist in the clubs producing a quantified plan to upgrade to the most water efficient products over time. It may also assist in defining those facilities where grants or other incentives are available for replacement. At the same time, any leakages or faults can be noted and repaired to minimise wastage.
