Forrest wastewater investigation

Barwon Water and Colac Otway Shire Council are partnering with the Forrest community to investigate opportunities for wastewater improvements in the township.

This partnership acknowledges the growing role tourism plays in Forrest and the regional economy, and the increasing stress this may place on existing wastewater systems in the town.

Members from the Forrest community have formed the Forrest Wastewater Group to facilitate early discussions with Barwon Water and the Colac Otway Shire.

These groups are working together along with the broader Forrest community to better understand wastewater issues for the community and options to identify solutions.

    Next steps:

    Through completing the preliminary business case, we identified a need to undertake a detailed economic assessment and cost benefit analysis to confirm the economic case for the project to proceed.

    We are now commencing this next step and will be meeting with our regulatory stakeholders in the coming weeks. This assessment and analysis will assist with identifying funding opportunities for the potential delivery of the community’s preferred wastewater solution.

  • Wastewater solutions business case phase

    5 months ago

    Barwon Water and Colac Otway Shire hosted a wastewater solutions assessment session in early October 2018, followed by a paper based survey inviting community members to nominate their preferred wastewater solution.

    Since this time, our technical consultants have been using this feedback to assess all four solution packages against the community’s agreed wastewater vision and associated success measures.

    While there was a range of views, Solution 3 received the highest level of support from the community and was therefore nominated as the preferred solution. This solution involves upgrading onsite systems (where necessary) to contain wastewater on...

    Barwon Water and Colac Otway Shire hosted a wastewater solutions assessment session in early October 2018, followed by a paper based survey inviting community members to nominate their preferred wastewater solution.

    Since this time, our technical consultants have been using this feedback to assess all four solution packages against the community’s agreed wastewater vision and associated success measures.

    While there was a range of views, Solution 3 received the highest level of support from the community and was therefore nominated as the preferred solution. This solution involves upgrading onsite systems (where necessary) to contain wastewater on individual properties, with an additional, centralised system to handle excess. This solution was also supported by technical experts.

    Both the Barwon Water Board and Colac Otway Shire Council have agreed to move the project to the business case phase, which will further investigate the preferred solution, identifying project benefits, governance and funding opportunities to facilitate the potential delivery of the solution that is affordable to residents.

    A steering group made up of Barwon Water, Colac Otway Shire, the Environment Protection Authority, Regional Development Victoria and the Department of Environment, Land, Water and Planning, with support from technical experts, has been established and will be involved in the business case development.

    Barwon Water and Colac Otway Shire expect the business case will be shared with the local community in the first half of 2019 and will continue to keep the local community of Forrest and key stakeholders informed as the project progresses.

    Barwon Water Strategy and Partnerships General Manager Kate Sullivan said the four solutions incorporated community feedback and included innovative stormwater and greywater treatment, partial onsite containment, offsite treatment and pressure sewer systems.

    20 people attended the session and they were able to talk with the project team, review the possible solutions and provide feedback.

    Some of the feedback included making sure potential solutions were designed for the long-term, cost effective and affordable, supported the town during peak tourism periods and incorporated innovative elements such as the use of recycled water in the township.

    The project will now move into the solutions assessment stage, where another community session will be hosted in early September, 2018.

    “At this session, the community will be able to have their say and assess each solution against the community vision and associated criteria with the view to making a community recommendation on a wastewater solution for Forrest,” said Sullivan.

    In addition to this, the Colac Otway Shire Council will be conducting follow-up wastewater audits on properties in Forrest that could not access previously and liaising property owners previously audited in late 2017.

    Colac Otway Shire Council Development and Community Services General Manager Gareth Smith said Council will work with property owners to determine what might be needed to ensure their system is functioning properly.

    The wastewater investigation is expected to be completed by the end of the year.

    Barwon Water and Colac Otway Shire Council will continue to keep the community informed as the project progresses.

    The wastewater audit (undertaken by Kernow Environmental Services) was completed in November, 2017 and found that there were significant and widespread issues relating to onsite wastewater management across the town (read the wastewater audit results summary here).

    Feedback from the community consultation has been mixed. While all agree the environment and character of Forrest needs to be protected, there are differing views as to both the extent of the problem, and the cause. What’s not in dispute it that any solution must avoid cost to the community and residents (read the full community feedback report here).

    A draft community wastewater vision statement and associated aspects has been developed in light of the survey and workshop feedback, we are now inviting the community to provide feedback on this draft vision in order to finalise so the vision can be used to assess and develop wastewater solutions for the town.

    To provide feedback, please complete the survey or leave a comment.

    Barwon Water will be in Forrest throughout February and early March in the lead up to the next community session where the community will have the opportunity to develop wastewater options for the town.

    Dates and times of these sessions will be communicated shortly.
