Phase 2 Biological Nutrient Removal/Tertiary Treatment Project

City of Modesto

Construction Cost: $102 million

West Yost provided construction management and inspection for this $102M wastewater treatment plant project which included a 12.6 mgd advanced treatment system and two-mile pipeline to the outfall location on the east embankment of the San Joaquin River.

Facilities included:

A key element was West Yost’s development of 3D models of the new facilities at the Modesto plant. These models provide a valuable tool for the West Yost CM team, the contractor, and the operations staff to identify conflicts, conduct preplanning work, and address access requirements and operational issues.
