The 30-Year Plan for Greater Adelaide (30-Year Plan) has identified the Le Fevre Peninsula as an area for significant growth. It is expected that future development will be concentrated in the northern part of the Peninsula resulting in additional wastewater flows. Historic growth rates are significantly less than those adopted for the 30-Year Plan and, therefore, a staged approach is appropriate to avoid over investment in infrastructure.
Existing wastewater infrastructure in some areas of the Le Fevre Peninsula is already operating at maximum capacity and isn’t able to accept additional flow. In particular, large areas of the wastewater network leading to the Ethelton Pump Station are at times operating at more than 100% capacity and are in need of a capacity upgrade.
We are upgrading the existing pump station at Dover Terrace, Largs North and installing a new rising sewer main from Dover Terrace to the Ethelton Pump Station. This will improve the capacity of the existing network and support the management of odours in the area.
The existing pump station at Dover Terrace, Largs North delivers wastewater via a rising main into a gravity main at Fletcher Road, Peterhead. During some flood peaks, the system is unable to cope which has resulted in some manholes surcharging. In addition there have been complaints regarding odours emanating from the Dover Terrace Pump Station and the gravity main that transfers wastewater to the Ethelton Pump Station.
We will continue to keep you updated on the progress of these works once a contractor has been appointed. If you would like to discuss this project further, please do not hesitate to contact our Customer Care Centre on 1300 SA WATER (1300 650 950) or by email to firstname.lastname@example.org.
Together with our contractors, Fulton Hogan Construction Pty Ltd, we are upgrading the existing sewer network that services the northern Le Fevre Peninsula.
The pipeline will follow a route that includes Narkunda Street, Jetty Road, Mead Street, Semaphore Road, Causeway Road, Bower Road and Bartley Terrace.
The new pipeline is being installed using a construction method known as directional boring rather than the traditional open trenching technique. Directional boring requires less excavation resulting in a reduced impact on nearby residents and road users. Installation of the new pipeline began in July 2018 and is expected to be completed by January 2019. Work to tie the new pipeline into the Ethelton Pump Station will see some impact to local residents and motorists using Bartley Terrace in November. Nearby residents and motorists will receive advance notification of these works in the coming weeks. Upgrade work at the Dover Terrace Pump Station is expected to begin in November 2018
We will work closely with the local community to ensure any construction impacts, such as access arrangements, are minimised.
Construction hours are Monday to Saturday between 7:00 am and 6:00 pm. If night works are required at any stage, nearby residents will be notified in advance.
Traffic management, including speed restrictions, detours and temporary parking restrictions, will be in place during these times to ensure the safety of our work crews and the community.
What you’ll see: During these works you may see multiple construction crews, material storage and the use of heavy machinery including excavators and a directional drill. You may also experience increased noise, dust and traffic disruptions. Our crews will work to keep these impacts to a minimum.
Temporary interruptions to water supply will be required at certain times during the works. If your residence is affected, you will receive advance notification at least four working days’ prior to any water supply interruption.
