San Jacinto wastewater treatment plant upgrade expected to finish this November

January 23, 2014

It will take until November this year to finish the upgrade of a wastewater treatment facility that serves the San Jacinto Valley area in Southern California, according to local officials. About 90% of the work is complete on the $157 million San Jacinto Valley Regional Water Reclamation Facility upgrade project, the Press-Enterprise reports.

Once the upgrade is completed, the plant will have a daily capacity of 14 million gallons of water, up from 11 million gallons. Expectations are that the facility will meet the needs of the San Jacinto Valley area until the middle of the next decade.

Funding for the upgrade has come from several sources, the bulk of it being a $145-million loan extended by the state Water Resources Control Board. The government has also chipped in, providing a $4.9-million grant.

Rehabilitation work will make parts of the existing facility suited for continued use but much of the project involves new construction. Erik Jorgensen, senior civil engineer at the Eastern Municipal Water District, said that the new additions were designed to make the plant compliant with tougher state rules for wastewater treatment.

Plant manager Matt Verosik commented that the removal of nutrients from the wastewater was done primarily by micro bacteria placed in new rectangular basins. The reclaimed water produced during the treatment process can be put to use in agriculture or serve for landscape and park irrigation purposes. The remaining sludge is transported by trucks to Arizona on a daily basis and is used for land application in agriculture, Verosik added.
