Hawthorn Sewer Improvement Project
We improved 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 inspected the existing pipes in the Hawthorn area, and over 50 kilometres of pipes were identified as being old or in poor condition, or had experienced multiple pipe blockages over the last few years.
Between December 2017 and August 2018, our contractors Interflow and Abergeldie improved these pipes, giving them a further 50 years of use, and reducing the likelihood of sewage spills into the environment during heavy storms.
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 were completed in August 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.
