Wamuran Irrigation Scheme D&C
About the project
The Wamuran Irrigation Scheme is being designed and constructed with the intention of delivering Class A recycled water to agricultural irrigation. Unitywater engaged the WIS JV (Pensar is a partner) to deliver the scheme infrastructure and ensure its maintenance into the future.
Location
Wamuran, Queensland
Client & Duration
Unitywater
Design Phase March 2020 - June 2021, Construction Phase January 2022 - November 2023
Project Scope
- The $100 million project sees Pensar designing and building a network of pipelines, pump stations and reservoirs to deliver recycled water from the Caboolture wastewater treatment plant to the Wamuran Valley some 25km away.
- The system will deliver more than 2.6 gigalitres of Class A water per year to the region’s growers – reusing a valuable resource and diverting discharge from local river systems.
- Unitywater engaged the WIS JV (Pensar is a partner) to design and deliver the scheme infrastructure.
Challenges
- Working with, and upgrading where needed, varying existing assets
- Creating a scheme design solution, meeting the increasing needs of sewerage treatment and disposal as a result of the forecasted population growth for the Caboolture River Catchment
- Taking into consideration the varying crop types, water quantity required and differing times of day/year irrigation takes place
Achievements
- The WIS JV worked closely with Unitywater, AECOM and Hydroplan to deliver a design meeting the scheme requirements of delivering Class A recycled water to farm gates
- Undertaking a customer focused design methodology, placing customer requirements at the forefront of the concept design
- Incorporating the upgrade and repurpose of existing assets including pump stations and Moodlu Quarry and the design of 25km of new pipeline, running to farm gates
