Hawthorn Sewer Improvement Project
We’re improving the condition of over 50 kilometres of sewer pipes in the Hawthorn area to reduce the likelihood of sewage spills during heavy storms.
Underground sewer pipes in Hawthorn collect sewage flows from properties and transport these flows to Melbourne Water’s sewage treatment plants in Werribee or Carrum for treatment and disposal.
The sewerage system in Hawthorn includes some pipes that are over 100 years old.
We’ve inspected the existing pipes in the Hawthorn area, and will be improving the over 50 kilometres of pipes that were identified as being old or in poor condition, or have experienced multiple pipe blockages over the last few years.
Improving these pipes gives them a further 50 years of use, and reduces the likelihood of sewage spills into the environment during heavy storms.
Timeline of works
Sewer improvement works started in Hawthorn in December 2017, and should be completed by mid-2018.
To complete our works sooner, we have engaged two contractors, Interflow Pty Ltd and Abergeldie Watertech Pty Ltd, who will be working in different parts of Hawthorn at the same time.
Interflow and Abergeldie will work between 7.00am and 6.00pm, Monday to Friday. Some Saturday work may be required from time to time, and would occur between 7.00am and 3.00pm.
We will notify residents in advance of upcoming works in their area or on their property.
While most of these works will be completed during daylight hours, to avoid causing traffic congestion in some of the busier roads in Hawthorn, we will need to undertake our works at night.
Night works will occur on weekdays between 10.00pm and 5.00am.
If works are occurring on your property or in your area, you should have received written communications to let you know whether these works were being completed by Interflow or Abergeldie.
Future works in the Hawthorn area
While Yarra Valley Water’s works to improve the condition of over 50 kilometres of sewer pipes in the Hawthorn area will be completed in mid-2018, other sewer improvement works will be undertaken by Melbourne Water from late 2018.
Over the next three years (2018-2021) Melbourne Water will invest over $100 million in a sewer relining and manhole rehabilitation program to upgrade 15 kilometres of ageing sewer pipes across Melbourne. These works will ensure Melbourne continues to remain the world’s most liveable city.
