South Gippsland Water operates two mechanical wastewater treatment plants at Leongatha and Korumburra. These plants utilise equipment such as clarifiers, digesters and a belt press as part of the treatment processes outlined above.
Most of South Gippsland Water’s wastewater treatment plants are lagoon based systems. These specially designed and constructed wastewater lagoons allow natural biological processes to occur and as a result, these processes cleanse the water. The lagoons are designed with shallow bases to allow oxygen and sunlight to filter through the wastewater. In these conditions, micro-organisms thrive and in turn, consume the nutrients in the wastewater. In addition, UV sunlight acts as a natural disinfectant.
Some lagoon based treatment systems, such as the Meeniyan Lagoons and Wetlands, also involve the use of weed and reed beds. The weed bed at Meeniyan is designed to reduce nutrients and improve downstream water quality.
