Project goal:

Ensure reliability of water supply, wastewater disposal and stormwater drainage in Subiaco


In construction

Delivery Date:

May 2018

What’s happening?

Water Corporation is making a significant investment in Subiaco to proactively refurbish and renew water, wastewater and drainage infrastructure. This essential work will ensure Subiaco has a secure, reliable water, wastewater and drainage network well into the future.

Main Drain Upgrade (December 2017 – May 2018)

Construction of a new drain

The Subiaco main drain was installed over 100 years ago and due to development of the area over the last century the local drainage systems no longer have the capacity to protect local homes and businesses against flooding during large storm events.

The new drain will be constructed under the north side of the road on Churchill Ave between Townshend Road and Axon Street. This drain will fill with storm water during major storm events and allows the water to then soak into the soil, rather than conveying water through the traditional drainage system.

Work on the main drain upgrade is being carried out by Georgiou, an authorised contractor of Water Corporation and is progressing well. We anticipate the remaining construction work and reinstatement of areas affected will take around four months to complete.

Work hours will generally be 7am – 6pm Monday to Friday. Where appropriate, some work will be undertaken on Saturday to minimise disruption to businesses along the street and reduce the overall time on site. Often Saturday work will include street sweeping for around 1 hour between 9am -12pm for the duration of the project. 

Drilling machinery is currently being used to install the exterior of the drain. We anticipate this work will be completed by 22 January 2018. Following this work, the initial excavation will begin, and some minor demolition works will occur.  This should be completed within the week commencing 5 February 2018. We appreciate your understanding and patience while these noisier stages of construction work are carried out. Following these works, construction of the concrete slab for the drain lid will commence, and we will be sure to keep you updated of any impacts you may experience as a result of this next stage of work.

How will construction impacts be managed?

Based on ongoing community feedback, we have been working to ensure the impacts of construction are kept to a minimum by selecting the most appropriate methods. This includes using innovative trenchless techniques which will minimise the size of the site, overall time on site and allow access to surrounding businesses and homes as much as possible.

Traffic  management will be in place around the site for the duration of the project. Traffic Controllers will be on site to assist with traffic flow.
  • For the duration of the project a full road closure will be in place preventing through traffic down Churchill Avenue. Local traffic to properties will be maintained via both Townshend Road and Axon Street. 

  • On 18 and 19 January between 11am and 1pm a temporary closure will be in place to allow for work to be carried out on a small section of the north side of Churchill Ave, opposite 245 Churchill Ave. During this time, access to properties to the west of this area will be maintained via Axon Street, while access to properties on the east will be via Townshend Road.

Water Main Upgrade (Pipes for Perth)


November 2017 - March 2018

We have been working to upgrade the water main along Coghlan Road between Roberts and Subiaco Roads. We have completed construction and expect to connect the newly installed main into the wider water network in February - March. This connection will involve some excavation work along Thomas St and we will endeavour to keep the community updated as these works get underway.
