Project Summary

HIFraser delivered a vacuum drainage solution for a Sydney Police Station refurbishment.

During the recent renovation of a Sydney Police Station, local authorities had stipulated that the basement floor could not be impacted during works. Since the project required changes to the basement design to incorporate new holding cells including toilets and showers as well as custodial and processing facilities, EVAC vacuum drainage system was delivered to make the project possible.
