Kianga Sewage Treatment Plant wins engineering excellence award

02 Nov 2016

Eurobodalla Shire Council’s Kianga Sewage  Treatment Plant Condition Assessment project has won the 2016 Engineering Excellence Award for Innovation in Water Supply and Wastewater. The award is sponsored by the Water Directorate and was presented by Executive Officer Gary Mitchell at IPWEA NSW Excellence in Engineering Awards in the Hunter Valley on 27 October.

The judges said Eurobodalla took an innovative approach to enable the existing oxidation ditch used to process sewage from three villages to be taken out of service for a period, emptied, cleaned and have a detailed condition assessment carried out whilst still maintaining alternative sewage treatment for these villages.

The challenge was to process sewage for 6000 equivalent population through an adjacent disused Pasveer Channel of capacity for only 2000 equivalent population for the period of service.

Staff displayed innovation and dedication in modifying and installing temporary electrical equipment, jet and surface aerators, sludge pumps and decanting equipment that could be manually operated 24 hours per day over the period. The successful outcome of this operation was that Council can now proceed with augmentation of its existing oxidation ditch, extending the design life of the plant up to 60 years.

Congratulations to Eurobodalla and to the two highly commended projects: Glen Innes Severn Council’s Aggregates Off-Stream Storage, Stage 2 and MidCoast Water’s Our Water Our Future.
