Upcoming work with Water Corporation - Mount Eliza Reservoir upgrade

Water Corporation is upgrading Mount Eliza Reservoir to help ensure the reliability of water supply to Perth and the surrounding areas for decades to come.

What is happening?
Water Corporation’s authorised contractor Civcon, is upgrading ageing water pipes and valve infrastructure buried within the Mount Eliza Reservoir embankment site located in Kings Park. As part of this essential upgrade work, we plan to replace the inlet water mains and old valves, construct a new regulating valve building, valve pit and valve pit wall.

When is this work happening?
Work will begin 8 September 2021 and will be completed by early 2022. Work will be mainly completed Monday to Friday between 7am - 5pm and Saturday 7am – 2pm. To help reduce impacts, some early morning and night work may be required, however we will communicate this work ahead of time.

What impact will this work have?
Upgrade work will mostly be contained to Water Corporation's Mount Eliza Reservoir site located within Kings Park; however, some work will take place along the reservoir fence line along Wadjuk Way. This means visitors to Kings Park utilising Wadjuk Way may notice an increase in noise, dust, and activity in the area from machinery and trucks as they transport materials to and from the work site.

Traffic Management
Wadjuk Way will require occasional partial and full lane closures for short periods of time. Detours and traffic management will be in place during this time. A section of the footpath along Wadjuk Way near to where work is taking place will also be inaccessible. Traffic controllers will be available to safely direct pedestrians to the other side of Wadjuk Way. A detour will also be available for cyclists through Wardong carpark. We urge you to take extra care around the work area and observe the instructions of traffic management personnel and signage.

The upgrade work is designed to have minimal impact to Kings Park flora. We will continue to work with Botanic Gardens and Parks Authority (BGPA) to minimise impacts on the public and ensure the high standard of site presentation is maintained upon completion of work.
