After decades of reliance on groundwater, the City of Albuquerque and Bernalillo County developed the San Juan Chama Project to begin using surface water from the Rio Grande and from the San Juan/Chama Diversion. The major component of the project was a 92 MGD, state-of-the-art surface water treatment plant. PCL was awarded the contract in 2005, and completed this project in 2008. The plant included many complex components, with three major processes being flocculation/sedimentation, ozonation, and filtration. A few of the facilities constructed include the following: 10 MG finished water storage tanks, a finished water pump station (with the ability to pump a total of 184 MGD), 6 MG grit removal basins, eight-acre settled water storage basins, a settled water pump station, a rapid-mix facility, gravity thickeners, and others.
The plant has an extensive controls package and sophisticated security, and now has the capacity to supply up to 70 percent of the area’s future water supply.
