More than 3000 Coliban Water urban customers will benefit from the completion of the South West Loddon Pipeline.
Coliban Water contributed $2.7 million to the $89.9-million project; led by GWMWater. Approximately 1170 kilometres of pipeline will provide a raw water supply to properties across 2900 square kilometres in both GWMWater and Coliban Water service areas.
The new pipeline provides a more secure raw water source than the Loddon River system, the former source of raw water, which was being treated to supply drinking water to townships in the Coliban Water service area.
Coliban Water Manager Community Operations Mick Dunne said the raw water for the new pipeline, largely sourced from Grampians reservoirs, was of a more consistent quality, with reduced organics and salinity levels.
Bridgewater and Inglewood customers are now receiving the new supply and Coliban Water also has plans to connect urban water supply for Tarnagulla, Bealiba, Dunolly and Laanecoorie to the pipeline in the future.
Sporting and community facilities in Wedderburn and Inglewood have been able to receive fit-for-purpose water from the South West Loddon Pipeline to irrigate green areas. This is expected to reduce the demand for treated water in these towns during peak demand periods and provide a more cost effective alternative for the facilities.
Mr Dunne said the new connection was a win for the communities involved.

The South West Loddon Pipeline has provided a secure, readily available water supply for John and Ann Leach who run 5000 sheep with their son John at Rheola, near Bridgewater in Central Victoria. It has given them given back precious time to focus their attention on other demands around their Merino Sheep farming enterprise.
Dry seasons over the years meant they were forced to run sheep in mobs of 1500; carting water to on-farm tanks from February until season break.
“We used to cart water to our tanks two days a week during mid-summer,” John said.
John has set the farm up to supply pipeline water around their paddocks, meaning they can now run smaller mobs of between 100 and 400 sheep.
“It’s a good clean water source that we also use for spraying and cleaning machinery. The security pipeline water brings is a great asset!” John said. “It was a lot of money to connect, but I’m so glad we connected.”
When the big fires came through, local farmers used to arduously cart water in their tankers from the Loddon River to keep water supply up to the fire-fighting helicopter.
“Now with the pipeline in place, GWMWater have fire-fighting tanks scattered around the region. It’s great security for fire-fighting”, John said.

Dubbed the ‘best development for the region since electricity’, the pipeline provides a secure reticulated water supply to 1500 rural properties in areas surrounding Inglewood, Newbridge, St Arnaud and Wedderburn.
Murphy’s Creek farmer Deb Hancock said the pipeline had given their farm a future for their children, Campbell and Georgia.
“For us, the impact of the pipeline is hard to explain in words,” she said. “We were spending a lot of money trucking water from Bendigo; one year we spent $90,000.
“To not have to worry about water – Wow.”
Not only has their water security improved, but the quality of the water has made a difference to the health of their stock.
“The supply we get from the pipeline is absolutely phenomenal,” she said. “The animals love it; the sheep won’t even go near a dam anymore.
The sheep look amazing and that’s just because of the quality of the water. It’s exceptional.”
The pipeline also paves the way for future growth for their business.

Following the construction of the Wimmera Mallee Pipeline, the channel system and the infrastructure GWMWater used along the Dunmunkle Creek to operate it, became redundant.
GWMWater is responsible for decommissioning the redundant structures between Glenorchy and Boolite to return the creek to as close to its natural state as practical.

Project areaScopeProject Steering CommitteeTimeline |
Project Area
The project area starts at Glenorchy at the south end of the creek, to Boolite in the north.
Scope
GWMWater has inspected all assets and developed recommendations for each to either remove, partially remove or transfer the management of assets to other organisations or landholders.
This includes structures such as bridges, culverts, regulators and other structures.
The project also requires earthworks along the remaining channel banks to help slow and disperse water flow.
Project Steering Committee
GWMWater has appointed a Project Steering Committee which works collaboratively to oversee the decommissioning or handing over of assets and includes representatives from GWMWater and:
- Wimmera Catchment Management Authority
- Northern Grampians Shire Council
- Yarriambiack Shire Council
- Department of Environment, Land, Water and Planning
- Regional Roads Victoria
- Landholder representatives: Howard Cooper of Glenorchy, Ian Taylor of Lubeck and Jason Mellings of Boolite.
Our landholder representatives will provide an important conduit between the community and the project team. If you would like to get in touch with any of the three landholders representatives, please call 1300 659 961 or
Timeline
We have been working closely with landholders to explain the proposed works and the terms of any removal or transfer of assets as well as the installation of breaks along the creek. We have completed all consultations with landholders impacted by the project where we were successfully able to make contact. If you, or someone you know, believes they are impacted by this project but haven't been consulted, please
We are now working to develop a proposed works plan which will be shared with landholders ahead of any works starting.

View our Compliance and Enforcement Strategy
Compliance and enforcement are two separate concepts that work together to maintain the integrity of water markets and sustain public confidence in Victoria’s water management.
- Compliance is proactive regulatory activity to prevent breaches or offences from occurring in the first place.
- Enforcement is a reactive regulatory activity that is triggered when breaches of the law are detected. Enforcement actions under the Victorian Water Act 1989 include warning notices, suspension or cancellation of an authorisation (e.g. Take and Use Licence), and prosecution.
This Compliance and Enforcement Strategy applies to surface water (including farm dams) and groundwater resources. This Strategy does not directly apply to GWMWater’s urban customers and rural pipeline customers, who are subject to the respective Urban Customer Charter and Rural Customer Charter. However, we do still undertake compliance and enforcement activities across our urban and rural pipeline districts.
Our Role
Water is a precious and limited resource. It is critical to our economy, environment and communities. This is why water needs to be managed fairly for all water users.
GWMWater has responsibilities under the Victorian Water Act 1989 to manage the compliance and enforcement of water taken from the water sources within its jurisdiction. The Water Act 1989 operates to promote fair, efficient and sustainable use and management of Victoria’s water resources for the benefit of water users, communities, the environment and the State.
Our Strategy
GWMWater’s Compliance and Enforcement Strategy provides details our approach to compliance and enforcement across (non-urban) surface water and groundwater sources. The Strategy outlines the range of compliance and enforcement tools available to us, and our risk-based approach to Compliance and Enforcement activities.
We have also produced a summary Compliance and Enforcement Factsheet.
Letting us know about misconduct
You can report any suspected non-compliance with the Water Act 1989 or suspected water theft across our urban and rural pipeline districts by contacting our Water Investigations Officer through any of following:
Mail: PO Box 481, Horsham, VIC, 3402
Telephone: 1300 659 961

Reporting on Compliance and Enforcement Activities
Each year we report on our Compliance and Enforcement activities through our Annual Report.
