**April 2026 Update**

For installation of bypass pipework between 7 and 10 April 2026 Cudmore Tce outside of our pump station will be closed in both directions between 9am and 3pm. Detours will apply. The Hill Street intersection with Cudmore Tce will be closed for approximately 5 months - access to Hill Street is via Chambers Street only. Access will be maintained to driveways for all residents. Traffic controllers will assist residents of Lawrie Street west of Northey Ave to enter and exit from the Northey Ave side.

For more information please see the works notification attached.


Together with our delivery partner, John Holland Guidera O’Connor Joint Venture (JHGOJV), we are undertaking a major upgrade of wastewater infrastructure to ensure we can continue providing reliable wastewater services into the future and meet projected wastewater demands for the Henley Beach area beyond 2030.

The Cudmore Terrace Wastewater Pump Station, which services around 10,000 connections and pumps wastewater to the Port Adelaide Relift Pump Station, is showing significant deterioration and no longer has the capacity to meet future demand. To ensure continued reliable service, we will be replacing approximately 425 metres of the existing rising main and rehabilitating the pump station to increase pumping capacity and improve long‑term operational reliability.

The project originally commenced in April 2024 but was paused after a failed section of the rising main was identified. Investigations confirmed that the affected pipeline must be replaced before pump station upgrade works can proceed.

Project timeline

Phase 1 – Rising Main Replacement

Installation of a new 400‑metre wastewater main along Lawrie Street and Cudmore Terrace is scheduled to occur between late February and July 2026.

Phase 2 – Pump Station Upgrade

Upgrade works at the pump station on the corner of Cudmore Terrace and Hill Street (previously scheduled for 2024) will now take place from July to December 2026.

The full project is expected to be completed in early 2027. Work will be delivered in stages throughout the year.
