Mernda Tank Project

Yarra Valley Water is constructing a new water reservoir tank in South Morang to secure water pressures for customers in the area.

As Melbourne’s Northern Growth Corridor continues to expand, so do the number of customers in the Mernda and South Morang areas. As a result, a need to update Yarra Valley Water’s infrastructure by constructing a dedicated tank for Mernda residents was identified.

Tank construction works

The new Mernda Reservoir water tank will be 35 metres in diameter and 15 metres high. It will be constructed of welded steel to help ensure the water is free of microbiological contamination. It will hold 12 million litres of water – that’s about five Olympic sized swimming pools.

The specific site for the tank is on top of the hill near Cravens Road and Hunters Road, land purchased over a decade ago by Yarra Valley Water. Construction was deferred until population growth in the area demanded it. Whittlesea council are planning to enhance the surrounding area as Granite Hills park, which is part of their wider Quarry Hills bushland park master plan. More Information can be found on the Whittlesea Council website. 

The Mernda tank’s top water level is about 250m above sea level, which will place it about 80 metres higher than houses in the service area.

Tank construction is scheduled for completion in late 2019.

Once the tank is built we will be asking the community for ideas on native tree planting, murals and other ways to beautify the park so it will eventually be a lovely area for the whole community.


Cravens Road construction works

Approximately 230 metres of new water mains need to be constructed under Cravens Road to connect the tank site to the water network. These works are scheduled to commence in July and are expected to take about eight weeks, subject to suitable weather and ground conditions.

Please refer to the below map of where construction will occur.

Community impacts

There will be no planned disruptions to your water and sewer services due to these works. 

Despite our efforts to minimise the impacts on the local community, you will at times notice construction noise, dust, and traffic disruptions. 

A Council-approved traffic management plan will be in effect to ensure workers, pedestrians, cyclists and motorists are safe. We will ensure you always have access to your driveway.
