**August/September 2026 Update**

Works to lay the wastewater main across Cudmore Terrace will commence from 2 September 2026 and are expected to conclude in late October. This will involve a full closure of Cudmore Tce between Harrison St and Marlborough St with a detour in place using North St and East Tce. For further details please see the notification letter 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 October 2026. Phase one will have four different stages as we work along Lawrie Street and Cudmore Terrace.

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 late 2026.

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

    Hello, thanks for your question. When we commence the pump station upgrade in phase two of our works the existing surge vessels will be replaced.  These works will also convert the existing conventional pump station set-up of dry well and wet well to a new submersible wet well pump station.  In a future output we will demolish the pre-existing structures.  Let me know if you require any further information.
