To meet new EPA regulations regarding the treatment of surface water run-off, the City of Tacoma hired Hoffman to construct a water filtration facility that includes pre-treatment facilities, flocculation, sedimentation and filtration structures, and improvements to the chemical feed, electrical power, and process controls of its existing facilities. Hoffman met difficult challenges such as tying into live systems without disrupting operations and re-purposing existing facilities to build what is now the largest filtration facility in the state. The facility has the capacity to filter 150 million gallons of water a day (MGD), well above the 110 MGD typically needed in the peak summer season. The project was delivered $7 million below budget and two months ahead of schedule. The early delivery allowed the city to fine-tune its automated systems before the plant’s EPA-approved classification as a filtration facility officially changed.
