Provost & Pritchard recently completed several areas of work associated with the upgrade of the wastewater treatment and disposal facilities for the Pixley Public Utility District. The existing facilities were constructed in 1949 and needed to stay in operation during the construction of the new facilities. Provost & Pritchard served as the resident engineer and provided construction review services. Prior to the redesign, flows at the treatment facilities were approximately 300,000 gallons per day. The new design accommodates 500,000 gallons per day, and includes a new influent lift station, new headworks, activated sludge treatment with nitrogen reduction, aerobic sludge digester, blower building, sludge drying beds, a new disposal pond, a new building to house the electrical facilities and an office. The project includes reclamation of adjacent property with treated effluent.
