<strong>Eurobodalla</strong> <strong>Integrated</strong> <strong>Water</strong> <strong>Cycle</strong> <strong>Management</strong> <strong>Strategy</strong><br />

Updating the asset registers to ensure the asset information is complete and up to<br />

date.<br />

Improve the reliability and system operation of the sewerage systems through<br />

telemetry controls, oxygen injection and power supply.<br />

Medium to Long term <strong>Water</strong> <strong>Cycle</strong> <strong>Management</strong> Opportunities<br />

Enhancements to the STP capacity and effluent quality using one of the following<br />

measures,<br />

Based on Studies done for Batemans Bay and Tomakin it appears that the<br />

performance of Kianga plant could be optimised by chemical dosing to<br />

accommodate the projected loads,<br />

Adding a parallel secondary treatment facility,<br />

Odour concerns could be addressed through:<br />

− Odour bed and scrubber to neutralise the smell at plant inlet works,<br />

− Protection of buffer zone from future development.<br />

Opportunity<br />

Option 1 – Plant performance<br />

optimisation strategy<br />

- Reticulation improvement to<br />

fix major I/I problem<br />

- UV plant to improve effluent<br />

quality<br />

- Optimise treatment plant<br />

operation<br />

Option 2 – Traditional strategy<br />

- Reticulation improvement to<br />

fix major I/I problem<br />

- UV plant to improve effluent<br />

quality<br />

- Parallel treatment train<br />
