Grey Infrastructure Projects

Grey Infrastructure Projects

Through Phase 1 of the SSIP, our planned improvements will upgrade our critical aging and seismically vulnerable grey infrastructure like pump stations, sewer pipes, transport storage boxes and treatment facilities into a state of good repair.

Wastewater Treatment Facilities Projects (Southeast Treatment Plant, Oceanside Treatment Plant and North Point Wet Weather Facility).
