East Lismore sewage treatment plant

During the flooding, the East Lismore Sewage Treatment Plant (STP) was completely flooded and all of the electrical equipment onsite was destroyed, rendering the plant inoperable. Lismore City Council and Public Works Advisory have been working hard to restore full operations at the plant and have successfully repaired key components of the treatment process.

Currently, the majority of the sewerage flowing to the plant is receiving a level of treatment and the quality of effluent being discharged has improved markedly. The quality of the effluent being discharged regularly complies with the prescribed discharge limits. However, while the repairs are underway the plant is not able to always comply with the discharge limits.

These repair works are ongoing and will gradually increase the level of treatment the plant is able to deliver and therefore the quality of effluent discharging from the plant over the coming weeks and months.

We have been conducting water quality monitoring downstream of the STP. The testing includes monitoring for metals, nutrients hydrocarbons and E.Coli. The results have confirmed that the discharge is impacting on downstream water quality and water from Monaltrie Creek should not be used for domestic, recreational or agricultural purposes. Water quality monitoring results from the Wilson River near the confluence with Monaltrie Creek are also elevated and the water should not be used for domestic, recreational or for watering stock or vegetables. We are continuing to monitor downstream water quality.
