Wastewater Pipeline Duplication in Rockingham

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

back to current projects

Project goal:

Installing a new 3.8km section of a below ground treated wastewater pipeline and a transition tower at Point Peron Wastewater Treatment Plant to cater for expected growth and increase in wastewater flows.

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.

Why is this work taking place?

Upgrading the wastewater infrastructure will cater for population growth and increases in wastewater flows.

When is this happening?

Construction is expected to start in early 2020 and 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 pipeline route and have prepared a Construction Environmental Management Framework and associated management plans to minimise impacts to the environment.

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 key stakeholders over a number of years.

As part of the consultation four pipeline route options were identified and 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 within the existing pipeline easement. Approval were pursued on the preferred route.

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.

Department of Water and Environmental Regulation assessed the project in 2019 with respect to the clearing of native vegetation and dewatering required during construction and issued the relevant approvals. As part of these approvals, Water Corporation will be revegetating 1.8ha of land within the Point Peron Bush Forever site to offset the clearing.

All external approvals required for the project have been obtained.
