GSV Report 56 - A pilot study of groundwater recharge at Carrum using treated effluent
 |
| |||||
Product description:Abstract Recharge experiments conducted by the Department of Minerals and Energy have shown that the treated sewage effluent produced by the South Eastern Purification Plant can be injected into the confined Older Volcanics basalt aquifer at Carrum. Although there was a fall in the injection rate during the six week injection test, 83 per cent of the optimum volume was injected and clogging was not an apparent problem. Any bacteria present in the effluent can be removed by chlorination but the possible presence of pathogenic viruses may necessitate additional treatment, and further research is required in this area. The effluent and native ground water are chemically compatible and combine together to produce a water that is of better overall chemical quality than either parent source. The promising results achieved at Carrum encourage further investigation in the Westernport Basin where a zone of groundwater depletion has developed as a result of seasonal overpumping form irrigation bores.
