• Covalent Lithium Refinery Project


    ATCO is preparing to supply commercial gas to the Covalent Lithium refinery on Mason Road in the Kwinana industrial area. 

    In order to do this, ATCO is required to construct a steel pipeline from the Covalent refinery boundary, southward along Mason Road. About 700m of pipeline will be laid along Mason Rd to connect with our existing tie-in point south of Thomas Road.

    ATCO is working with the City of Kwinana and the Kwinana Industries Council to understand the traffic environment and minimise disruptions.


    Use our map below to view the progress of works along Mason Road:


    Construction works are planned to start in early April and finish in early June 2023.


    • What areas are affected by ATCO works?

      Our pipeline construction will occur along the western-side of Mason Road starting near Covalent Lithium and moving southward towards the ARC rail corridor. 

      Before we reach the rail corridor, ATCO will cross to the eastern-side of Mason Road and commence underground drilling. We will continue southward, drilling under the rail corridor and Thomas Rd, to connect to our existing pipeline near Accensi.

    • When are ATCO works expected to start?

      Construction works are planned to start in early April and finish in early June 2023.

    • Will there be impacts to traffic or business access?

      Due to the proximity of our works to Mason Road, traffic management will be in place to ensure the safety of our crews and local traffic. Traffic delays and some noise are expected while works are underway. Updates will be provided to local businesses, as well as reflected in the map above.

      Please follow all directions from ground crews and traffic management.

    • Will there be road closures?

      It is unlikely any roads will be closed during our construction works. 

      However, for the safety of ground crews and road users, there may be some temporary lane closures in certain areas. In these cases, ATCO will endeavour to provide advanced notice to businesses about the planned traffic management. 

    • Will the work be noisy?

      Construction noise during works is expected, but we will do everything we can to reduce the noise of the works during business hours: most likely between 7am and 7pm Monday to Friday.

      Noise management plans will comply with council guidelines.



    • How will the work be done?

      Our process involves using a combination of open trenches and trenchless technology to install gas mains. 

      The trenchless method greatly reduces the time needed to complete works as well as reducing the impact to road users and businesses in the area.

      Excavations will still be required predominantly along Mason Road to get the pipes underground, however traffic controllers will be onsite to ensure local traffic can move safely around the area.

    • Will there be interruptions to gas supply?

      No, there are no planned interruptions to gas supply as a result of these works.
