CWMS Extension: Rosetown, Wyomi and Pinks Beach

Council undertook community engagement about the proposed Community Wastewater Management Scheme (CWMS) Extension to Rosetown, Wyomi and Pinks Beach. Consultation was open from 11 June 2025 to 9 July 2025.

The engagement sought to:

Build awareness and understanding of the environmental, health, infrastructure and financial benefits and impacts of the project; and
Understand how Council can best support property owners in the delivery of the CWMS, including payment options and onsite works.

The purpose of the engagement was to ensure that property owners had the opportunity to provide feedback on the proposed extension to inform Council's decision making.

651 information packs were distributed to property owners about the project. In addition, two information session were held, in person and online, along with three drop-in sessions held locally to provide further information about the proposal.

Engagement opportunities were promoted through Council's website, newsletter and social media as well as direct mail and posters to local businesses. Thank you to all of the property owners who attended and participated in the information sessions that were held and provided feedback via the online form. We appreciate the opportunity to share information and receive your feedback on this important initiative for our community.

A total of 107 written responses were received during the engagement period. These responses represented property owners of 134 properties. There was good representation from all areas proposed to be serviced by the CWMS expansion in the feedback received. Responses were received from property owners with dwellings as well as those with vacant land.

A detailed Engagement Summary Report summarising all the feedback received is available here.

At the 22 July 2025 Ordinary Council Meeting, Council considered the outcomes of the engagement process and resolved to commit to extend the Community Wastewater Management Scheme to the areas of Rosetown, Wyomi and Pinks Beach by formally requesting funding from the Local Government Association of SA.

Project Summary

651 properties to be connected in the areas of Rosetown, Wyomi and Pinks Beach - 270 of which are vacant allotments;
Project cost of approximately $25 million, with an indicative grant subsidy of $18.5m to underwrite the costs to property owners. Final funding figure will be confirmed through detailed design, which is expected to occur in the coming months;
Connection fee per property $7,448 (SA Water equivalent for 2025-26 – adjusted annually and will be locked in at the time of commissioning construction);
Residents are encouraged to consider this project as risk mitigation for your property, as many on-site systems, if non-compliant with current regulations, are likely to require installation of a holding tank, due to small block sizes and proximity of the many bores. This upfront and ongoing costs (or a replacement on-site system where still possible) will be many thousands of dollars more for those properties in the future, than the heavily subsidised cost with the subsidy/grant Council hopes to secure;
Connecting properties to the CWMS will protect our precious groundwater by addressing the current risks to public health and the environment from aging and non-compliant on-site wastewater systems, mitigate the future costs of replacement of failing systems, and in all likelihood increase property values, amenity and appeal of our township;
These factors have culminated to our community having now been prioritised for funding consideration through the statewide LGA grant program, ahead of many other Councils which are seeking to access the program for similar CWMS upgrades;
Although SA Water has indicated it has no plans at this stage for extending potable water supply into these expansion areas, Council is liaising with its ‘Water Futures’ team about the benefits and efficiencies that can be taken advantage of, if this aspiration were implemented at the same time as the construction of the CWMS extension. Council will continue to advocate for this and provide further updates when available; and
Treated reuse water is expected to be made available to the Kingston golf course, while also servicing other parks, ovals and foreshore amenity watering needs.

Project Update as at 6 February 2026

Kingston District Council has secured further funding from the State Government funded CWMS Program, which is delivered by the Local Government Association of South Australia, to undertake detailed design work for the extension of the Community Wastewater Management System (CWMS) into the Rosetown, Wyomi and Pinks Beach areas.

Detailed design is expected to be completed by late June 2026, ahead of consideration of funding for planning and construction of the expansion areas.

Council continues to work with SA Water’s Futures Team to explore the potential for potable water supply to be extended into the CWMS expansion areas. No commitment has been made at this stage.

Should potable water extension become feasible, Council will provide further information to affected property owners, including indicative connection costs when available, and will seek feedback on community support.

Additional updates and information sessions will be provided as the project progresses.
