SDOOL pipeline duplication

Upgrading wastewater infrastructure in the City of Rockingham area to cater for population growth.

back to current projects

Project goal:

Installing a new 3.8km section of a below ground treated wastewater pipeline in the City of Rockingham to cater for expected growth and to provide a reliable wastewater service.

Status:

In planning

Delivery Date:

2020-21

What's happening?

We’re installing a new 3.8km treated wastewater pipeline next to an existing pipeline in the City of Rockingham.

The pipeline, referred to as the Sepia Depression Ocean Outlet Landline (SDOOL), transports treated water from several wastewater treatment plants in the metropolitan area and other industries to the ocean outfall offshore from Point Peron.

Where is this happening?

We are installing the new section of pipeline from Ritchie Drive in Rockingham to the Water Corporation wastewater treatment site on Point Peron Road.

See the map of the proposed pipeline route.

Why is this work taking place?

Upgrading the wastewater infrastructure will ensure sufficient capacity to cater for expected population growth and improve the reliability of the wastewater network.

When is this happening?

Construction is expected to start in early 2020 and expected to take approximately 12 months to complete.

How will this impact the community?

We’re installing the pipeline in stages and access to areas along the route may be temporarily restricted for public safety including parts of the Lake Richmond walking track and picnic area and Bayview Reserve. We are planning to keep access to the Bayview Reserve dog exercise area available during the project. We’ll install signage and provide further updates, including consultation with residents directly impacted, as the project progresses.

Traffic management will be in place to direct residents safely around work areas.

We recognise the key environmental values associated with Lake Richmond and Bush Forever sites along the proposed pipeline route and we have prepared an Environmental Management Plan to minimise any impacts.

For parkland areas, we are working with the City of Rockingham to develop a plan to rehabilitate the area following the pipeline installation work.

We have been working with the City of Rockingham and key stakeholders over a number of years.

As part of the consultation it was decided to construct the new pipeline next to the existing pipeline to allow connections to existing infrastructure and to minimise environmental disturbance by using the land with the existing pipeline.

In 2012 the project was deferred due to a number of factors including slower population growth, asset condition of the pipe and investigations regarding future development in the area.

In 2017 the project was re-activated and we submitted our Development Application which received approval at the Metro South West Joint Development Assessment Panel on 18 July 2018.
