Central Valley Energy Recovery Project

In August 2013 ALPRO Energy & Water was awarded a contract to assess the feasibility of upgrading Central Valley Water Reclamation Facility’s existing treatment plant. AQUA Engineering is excited to be part of ALPRO’s team. The study evaluates upgrades to the anaerobic digesters, the hot water system, the gas treatment system, and generation system.  If the project is deemed feasible, ALPRO will be the solids manager  building and operating a receiving station that will accept municipal biosolids, FOG, and food waste products to be co-digested in the existing digesters.

Tooele WRF – Solar Drying Facility

AQUA Engineering provided engineering design and construction management services for the Tooele Water Reclamation Facility Upgrade Phases 1A and 1B. These upgrades included a new clarifier, additional aeration in the oxidation ditches, UV disinfection, biosolids dewatering, a sludge holding tank and a solar drying facility. Construction of the facility was completed in 2012 and the facility upgrade has won awards including “Top 10 in the Nation” from Water & Wastes Digested News and the Water Environment Association of Utah’s “Outstanding Biosolids Program Award”.

Oakley, UT – MBR Wastewater Treatment Facility


AQUA Engineering was contracted by Oakley City to design and build the first MBR (Membrane Bio-Reactor) facility in Utah.  The facility can treat 200,000 gallons per day using the Zenon Zeeweed hollow fiber membrane system. Other treatment technologies included the main pump station, headworks fine screening, anoxic basins, aeration basins, membrane tanks, UV disinfection, a small belt press for dewatering, full laboratory, electrical controls, and a full SCADA system for remote monitoring and operations. All of this was inside of a simple, barn-like building that blended into the surrounding area. Most residents have no idea that a treatment plant is in their neighborhood.

This project received the 2005 ACEC Grand Award for Engineering Excellence.
