Orford and Triabunna Water and Sewerage Strategy

Updated February 2017

TasWater has outlined the future of water and sewerage services in Orford and Triabunna in a long-term strategy. Our intention is to upgrade and rationalise the two towns’ ageing water and sewerage systems, to improve their reliability, performance and safety and to meet likely future demand.

There are a number of projects within the strategy, some of which are complete and others which will roll out progressively in coming months and years.

Future bulk water storage for Orford and Triabunna

During the 2006–09 drought, water stores on Tasmania’s east coast fell to very low levels, so TasWater’s Orford and Triabunna Water and Sewerage Strategy provides a plan for improved bulk water storage. The four dams currently servicing the area – namely the Upper and Lower Prosser dams, and the Brady and Maclaines dams – are all either undersized, at capacity or nearing the end of their design life. Rather than repairing and maintaining four separate dams, it is more effective to consolidate the area’s bulk water supply into one dam.

You can learn more about TasWater's investigations into possible locations for a new dam here.

Orford and Triabunna Water Treatment Plants – Critical Works Project

Now complete, these two projects have upgraded critical elements of the Orford and Triabunna Water Treatment Plants to ensure their continued performance. The project focused on minimising failure and performance risks, to provide the time to plan a replacement plant for the area.

Decommissioning of Holkham Sewage Pumping Station, Orford

Now decommissioned, the former Holkham Sewage Pump Station was subject to flooding and presented a risk to the public. The project has eliminated electrical risks and saves on operating costs.

Orford Sewerage Outfall Project

This project has replaced the damaged outfall pipeline at Quarry Point, which broke off in a storm prior to TasWater’s formation. This new pipeline provides better public health and environmental outcomes for Orford.

The Orford Sewage Pumping Station and Network Upgrade Project

This project will upgrade the sewerage network within Orford and includes upgrading or replacing ageing pumping infrastructure, and installing a new pipeline for pumping from the Prosser Pumping Station, near Prosser Bridge, to the Orford sewage treatment lagoons.

Triabunna Reservoir

This project will replace the existing reservoir with a new reservoir that will meet current standards and boost water pressures in the higher areas of Triabunna.

The project will minimise water supply risks and provide water pressure to meet fire hydrant standards. The project is currently in design phase and is planned to commence in 2017.

Orford to Triabunna main water pipeline

This project proposes a larger water pipeline from Orford to Triabunna. The current water pipeline acts as a backup supply to Triabunna. The new pipeline would increase the amount of water flowing between the two townships and ensure a sustainable backup supply for Triabunna.
