MWH served as the CMAR on this $49.4 million expansion project to increase the North Davis Sewer District’s digestion capacity. The project included construction of a new primary sludge screening and thickening facility, a new cogeneration facility, new primary digesters, dewatering process expansion, and upgrades to the existing secondary digesters. MWH implemented and managed all health and safety processes.

  • After the project was completed, both 100% of the plant’s process heating needs and 65% of the plant’s total energy needs were met.
  • There were 120,000 hours worked without a lost time incident.
  • MWH added approximately $900,000 in additional value or scope changes.
