James W. Fowler Co. (JWF) will work in partnership with the Santa Fe Irrigation District on the Mechanical Dewatering Improvements and San Dieguito Dam Improvements Projects. The projects include mechanical dewatering improvements to increase the efficiency in removing solids at the R.E. Badger Water Filtration Facility, handrail improvements at the San Dieguito Reservoir, and concrete refurbishment at the San Dieguito Dam.

The R.E. Badger Filtration Plant is a conventional water treatment plant that was built in 1970. It is owned by both the San Dieguito Water District and the Santa Fe Irrigation District. While the plant can treat up to 40 million gallons a day, and over 7 billion gallons of potable water a year, mechanical dewatering improvements will increase operational efficiency and decrease process costs. Until now, a great number of solids removed at the filtration facility have been discharged to the San Dieguito Reservoir. The project includes design and construction to remove and manage solids, an integral part of the water treatment process.

Constructed in 1918, the San Dieguito Reservoir has served residents in the area for over a century. The reservoir is used for storage of Lake Hodges water while also serving as emergency storage. Areas of rust and degradation that has occurred over time will be repaired and upgraded in accordance with current standards and regulations. The project will serve in upgrading the existing outdated guardrails and walkways to meet current safety standards.

Lastly, upon inspection it was determined the exterior face of the 1918 built San Dieguito Dam needs refurbishment. The project will provide concrete refurbishment, including repairs of concrete cracks and spalls, and blasting and recoating of the anchor steel plates to address surface wear.

JWF is proud to work with the Santa Fe Irrigation District in serving residents while working to provide safe reservoir working conditions.
