BMID Modernisation

About the project

Southern Rural Water is modernising the Bacchus Marsh Irrigation District (BMID).

New assets have been created and old ones upgraded to make the district more efficient, reliable and resilient to a drier climate.

The State Government committed significant funding to Southern Rural Water to implement its modernisation program in 2016. Construction commenced that year and has been undertaken in stages which will be completed and operational by 2021.

The BMID Modernisation works are progressing well, with Stages 1, 2A/2B, and Stage 3 completed, and the commencement of Stage 4 works in winter 2019.

Modernisation

 

Stage 1 - Maddingley Pump Station

In partnership with Moorabool Shire Council, a new pump station was constructed at Maddingley and a new rising main. The Maddingley Pump Station is operating and supplying customers along the new pipeline.

These works were undertaken ahead of schedule due to the extension of Halletts Way across the old alignment of the main channel near Werribee Vale Road.

Stage 2A – Maddingley Tank

SRW installed a new storage tank to replace the 80 year old Maddingley Basin in 2018.

The new tank increases system reliability and provides better supply pressure from Maddingley Hill to improve delivery as the old channels are converted to pipes during the BMID Modernisation project.

Stage 2B – Spur 2/2 Upgrade

The old Spur 2/2 pipeline was replaced by a new Glass Reinforced Pipeline following the existing pipe’s alignment through six SRW Customer Properties. These works were completed leading into the irrigation season of 2018-19.

Special consideration was given to the connection point near the Avenue of Honour to avoid impact on the heritage Elm trees along the road side. Consultation with Moorabool Council and a professional Arborist helped ensure the project was completed successfully.

Stage 3 - Replacing the old flume and channel in Werribee Vale Road

This stage of the project involved piping and removing an old flume (raised concrete channel), that was once a critical irrigation asset. This section of the original supply channel was a major cause of water losses while delivering irrigation water to the district.

The inefficient open channel winding along the roadside was replaced with 4km of new GRP pipeline. New modernised customer outlets have also replaced the traditional “waterwheels” still used elsewhere in the district.  These works were completed in winter of 2019.

Stage 4 - Pipelining the old channel from Bacchus Marsh to Darley

These works commenced in winter 2019, and involve piping 2.6 kms of old channel from the centre of Bacchus Marsh to the Lerderderg River in Darley.

Delivery points to council facilities, sports grounds and several customers have been updated as part of these works.
