East Grampians Rural Pipeline
About
The East Grampians Rural Pipeline is a major investment in the long-term water security of the region, delivering a reliable, high-quality water supply all year round.
GWMWater has awarded the construction contract to Mitchell Water Australia. The project includes installing new pipeline infrastructure to deliver water directly to rural properties, along with the construction of additional pump stations and water storages to support the system.
Reliable access to high-quality water will reduce risk for existing agricultural businesses and create opportunities for growth and expansion.
It will also support the development of new enterprises, helping strengthen the region’s economy now and in the future.
Beyond agriculture, the pipeline will improve water supply for the community and deliver broader economic, social, recreational and environmental benefits across the region.
The primary water source for the East Grampians Rural Pipeline will be Lake Fyans, with secondary supplies from the Mt William headworks and Mt Cole Reservoir, providing a resilient and dependable system.

Pipeline water access as the project progresses
As construction of the pipeline progresses and sections successfully complete hydrostatic pressure testing, some residents may be able to access an interim water supply through their meter before the project is fully commissioned.
During this interim phase, the water supply may not meet our standard service levels as outlined in the Rural Customer Charter.
However, pressure and flow should be sufficient to reduce the need for water carting until the full system is commissioned.
To check whether the interim supply is available at your property, please refer to the live map.
Water use and charges
Before accessing any water, residents must purchase their water allowance. Any water used during the interim supply phase will be deducted from your existing water allowance entitlement.
You will only be billed for the water you use during this period. No service charges will apply until we confirm that water services are fully commissioned.
Usage charges will be applied in accordance with GWMWater’s Schedule of Tariffs – Miscellaneous and Other Charges.
Connection requirements
In line with landholders’ Heads of Agreement, water from the meter must be connected directly to a storage tank with enough capacity to meet a minimum three-day peak demand.
A minimum 100 mm air gap must also be maintained between the tank inlet and the tank overflow.
For more detail, please refer to the relevant fact sheets below.
Note: Residents are reminded that the raw water being supplied through pipelines is not fit for human consumption. It may be used for household activities, such as watering gardens, flushing toilets, irrigation, showering/bathing and laundry.
