The Alkimos Wastewater Treatment Plant required upgrades to increase treatment capacity to 28 ML, supporting growth in Perth’s northern corridor and accommodating increased inflows resulting from the diversion of specific catchments.

Peritas was engaged to provide comprehensive consultancy services, including project management, site supervision, skilled labour, plant and materials, to deliver the necessary civil and structural works. The team played a key role in managing a significant operational transition at the plant while it remained in service.

Civil and structural engineering teams supported initiatives aimed at enhancing treatment capacity to accommodate base growth in the region, delivering a range of upgrades and modifications to the facility and ensuring all works complied with Water Corporation industry standards and performance requirements.
