Western Water (VIC) has begun work on a new replacement water main for Bacchus Marsh.
The water main will replace the existing one in Bacchus Marsh’s Avenue of Honour, an avenue of trees that serves as a memorial to local soldiers who served in the First World War.
The existing water main is very old and has frequent bursts that need complex repairs. These repairs are further complicated by the proximity of the Avenue’s trees.
The main will be replaced by a larger one that will provide better quality water services to around 70 customers in the area, including some of Bacchus Marsh’s popular food producers.
The main will also be big enough to cater to growing demand expected in the future.
Western Water is aware of the cultural and environmental significance of the avenue and its trees, and is working hard to ensure the lowest possible impact.
They have been working closely with the RSL, Moorabool Shire Council, Heritage Victoria and other stakeholders during the planning stage of the project.
The planning has included assessing environmental and geotechnical impacts, cultural heritage and location of other underground services such as phone and electricity.
An arborist has surveyed the trees to advise on protective measures, and will be closely monitoring the project to avoid damage to the trees.
The water main will be replaced within the roadway, as there is not space on the roadsides. This will mean one lane of traffic lane will usually be closed during the work.
Customers on the main will have their water supply turned off for short periods on occasions, such as when the new main is connected to their property. They will be notified in advance if this occurs.
The work will involve “trenchless” technology, which includes digging pits at intervals along the alignment of the main, and using horizontal directional drilling to tunnel under the road.
Sections of the main are then put in place individually and joined up. The new main is then connected to the network, and each property connected to the main.
The project is expected to take around four months, with completion due by the end of March 2016.
