Project Description

The Ellis Creek 6.7 mgd tertiary treated water plant involved construction of grit removal, oxidation ditches, clarifiers, bio-filters, tertiary filters, bio-filter odor control systems, disinfection systems, and administration, maintenance and operations buildings.

Monterey Mechanical’s scope of work included all architectural metals, HVAC and foul air ventilation systems. We were a subcontractor to Kiewit Pacific.

Challenges | Solutions

The wetlands that ring the Ellis Creek Water Recycling Facility are home to pelicans, egrets, herons, sandpipers, red-tailed hawks, western pond turtles, marsh wrens, and a wide range of other wildlife.

To protect the habitat during construction, Monterey Mechanical sequenced the construction activities to avoid mating season and implemented environmental awareness/sensitivity training for all workers.
