Boundary Creek and Big Swamp remediation

Recent technical work has confirmed that the operation of the Barwon Downs borefield over the past 30 years is responsible for two thirds of the reduction of base flow into Boundary Creek.

The dry climate experienced during the same period accounts for the remaining third.

This suggests that the lower sections of Boundary Creek would likely have no flow periods during summer regardless of groundwater pumping, however pumping has increased the frequency and duration of no flow periods in lower reaches of Boundary Creek.

The remediation of Boundary Creek and Big Swamp was identified as a community priority during the consultation for the Barwon Downs borefield groundwater licence renewal in the latter part of 2017.

Barwon Water has recently formed a community and stakeholder working group to develop a remediation plan for Big Swamp and Boundary Creek.

This group will work together to assist Barwon Water in designing and implementing a remediation plan for the creek and Big Swamp.

  • Remediation approach for Boundary Creek and Big Swamp environments

    Barwon Water welcomes the direction from the Minister for Water in relation to a legally enforceable remediation plan for the Boundary Creek and Big Swamp environments impacted by past groundwater extraction at Barwon Downs, under Section 78 of the Water Act 1989.

    Managing Director, Tracey Slatter said this not only provides added assurance to the community but legally enshrines Barwon Water’s intention to remediate Boundary Creek and Big Swamp as part of its application to Southern Rural Water to renew the Barwon Downs borefield licence.

    Managing Director, Tracey Slatter said this not only provides added assurance to the community but legally enshrines Barwon Water’s intention to remediate Boundary Creek and Big Swamp as part of its application to Southern Rural Water to renew the Barwon Downs borefield licence.

    “Barwon Water is keen to cooperate with the Section 78 notice and the licence application process to get the right outcomes,” Ms Slatter said.

    “We are also committed to working closely with the local community, key agencies and technical experts in the years ahead as we work towards achieving this,” Ms Slatter said.

    “We have been consulting with the community and key stakeholders to help Barwon Water design the remediation plan including identifying what the success criteria might be.”

    At the request of community members, three independent technical experts were invited to contribute to the process. These experts will work with Barwon Water’s existing technical consultant and the remediation working group to refine the remediation concept and address any important information gaps before finalising the plan.

    The formation of this group is in response to community feedback to improve stream flow and water quality of Boundary Creek, with the goal of returning the creek to a healthy ecosystem.

    The role of the working group will be to provide valuable local knowledge, suggest alternate options for remediation and foster and champion greater community awareness of the remediation plan

    At the meeting, the group participated in constructive discussion and established clear direction to address community and stakeholder concerns.

    Working group members also nominated a number of experts and and identify actions to help address information gaps and stakeholder concerns.

    The next working group meeting will be at the end of July.

    Barwon Water will continue to keep the broader community updated on the progress of the group.
