Environment Protection Authority Victoria (EPA) has granted a Works Approval to North East Water to upgrade the Benalla Wastewater Treatment Plant (WWTP) on Holdsworth Road.
NE Water has projected population growth in the region to the year 2050 will increase the average daily flows to the plant from around 2 megalitres (ML) to 3.71 ML.
The proposed upgrades are required within the existing boundaries of the premises to prepare for this growth.
The proposed works of the Benalla WWTP Upgrade have been designed under a staging strategy and include:
• decommissioning the existing maturation lagoons
• replacing the inlet works
• upgrading the existing aerated lagoon (aerators)
• replacing the existing maturation lagoons with new lagoons by stages
• providing new winter storage to match the size of the irrigation area
• upgrading irrigation pump stations/pipelines.
“The upgrade to NE Water Benalla WWTP will provide sustainable capacity for Benalla township, whilst protecting the surface water quality of Broken River. NE Water must provide EPA with an updated Environment Improvement Plan and Land Capability Assessment to ensure protection of soil and groundwater of the irrigation areas,” said Tim Faragher Director EPA Development and Infrastructure.
The proposed Benalla WWTP Upgrade works will continue to treat wastewater to Class C standard for irrigation reuse.
