In July 2007, the City Council authorized the construction of the new Water Treatment Plant Expansion Project. The project was a modular design and has the capacity to treat 21 million gallons of water per day. The work included the installation of two circular clarifier units, two gravity filters, a waste washwater recover basin, a raw water structure, an operations building and chemical building, the division of the two 25 million gallon earthen storage reservoirs and intereservoir connections, clearwell and backwash recovery pump stations, associated pipelines, grading, paving, electrical instrumentation and controls. The entire expansion was then interfaced with existing treatment facility.

On April 25, 2010, W.M. Lyles Construction Company completed the $26.6 million dollar project and it was placed into operation earlier than expected due to the 7.2 earthquake.
