The city of Westmorland owns and operates a wastewater treatment plant constructed in 1985 with an average daily flow capacity of 375,000 gallons per day (gpd). The plant provides secondary treatment by means of two aeration basins followed by four stabilization ponds. The treated effluent is discharged into an agricultural drain that flows into the New
River, a tributary of the Salton Sea.
In recent years, the plant had experienced problems with seepage of untreated wastewater from the existing ponds and the influent pump had deteriorated with age to the point that it was no longer reliable. In addition, the treatment system lacked the disinfection facilities required under its operating permit.
To correct these deficiencies and bring the plant into compliance with state water quality and health regulations, the city undertook a project to upgrade and expand the plant. Major components of the project included:
Improvements in the wastewater treatment system corrected deficiencies in the system thereby bringing the plant into compliance with state regulations, as well as reducing the likelihood of contamination and disease transmission from untreated wastewater seepage and spills. System expansion will also ensure sufficient treatment capacity for the
next 15 years.
