The City of San Luis has completed a new groundwater well and manganese treatment plant at Well Site 7, an initiative aimed at improving water quality and production capacity for local residents. The project, which represents an investment of $6,654,611.99, introduces advanced filtration technology to remove iron and manganese from the water supply.
Planning for the facility began in 2022 with conceptual design work. Engineering was carried out over 2023 and 2024, during which time the city procured key equipment including the filtration system and major electrical components. Construction began after a contract was awarded in 2024 and reached substantial completion by July 2025.
Eulogio Vera, Public Works Director, commented on the development: “The completion of the new water production well and manganese treatment plant at Well Site 7 is another major step toward strengthening our city’s water infrastructure. The project ensures that our water system continues to meet the growing demands of our community while maintaining the highest quality standards.”
The facility uses advanced media filtration to treat up to 2,400 gallons per minute. City officials highlighted that this effort is part of ongoing work to provide reliable and high-quality water services through strategic planning and responsible resource management.
The project involved cooperation among the Public Works Department, Water Division, as well as various contractors, consultants, and suppliers.
