Melbourne Water is building new infrastructure in the areas of Kalkallo, Beveridge, Bald Hill and Yan Yean to meet the growing demand for water in the northern and western suburbs of Greater Melbourne. 

What's happening and when

In April 2020, works commenced on construction of a 1.5km water supply pipeline and the installation of a large water tank on the top of Bald Hill, Kalkallo.

Works will involve excavation to establish a foundation for the tank and new pipeline. With a diameter of approximately 36 metres and 10 metres tall, the tank will be delivered to the site in segments and installed by crane.

What to expect

  • Frequent truck activity in the area to transport materials and equipment
  • Soil stockpiled on site and noise from machinery operating during work hours
  • We will have measures in place to manage dust and noise.

Due to start construction next year: 
Yan Yean to Bald Hill pipeline

Along with the smaller 1.5km pipeline and tank installation, Melbourne Water are also planning to build a new 20km pipeline to improve the reliability of water supply in the northern suburbs and free up capacity to transfer more water to the western suburbs.

The project involves construction of a new 20km pipeline from the Yan Yean Water Treatment Plant to the Bald Hill, Kalkallo tank site as shown on the map provided. We anticipate construction of the pipeline will commence in 2021. The tank and smaller infrastructure we are building now, will allow us to connect the tank to this greater pipeline in the future.

Why we are doing these works

The population of Melbourne is projected to increase from 4.6 million in 2016 to 6 million in 2031 and ultimately to 8 million people in 2051.

Around 60% of Melbourne’s population growth is expected to occur in Melbourne’s northern and western suburbs with a projected new 851,000 residents by 2031 (Victoria in Future 2016, Victorian Government).

The new pipeline has been designed and timed to meet growing water demands and improve reliability of supply in the northern suburbs, while freeing up capacity to transfer more water to the western suburbs.

As the new pipeline is being constructed to transfer water no connections will be made to properties along the alignment, however Melbourne Water will work with the Country Fire Authority to investigate emergency supply connections.

Melbourne Water is committed to delivering world-class solutions with minimal impact on the community, on businesses and on the environment.
