A multimillion-dollar construction project is almost done on a massive water tank in Mission Trails Regional Park. Once construction is complete, it will likely be forgotten because no one will be able to see it.

The San Diego County Water Authority is wrapping up construction on its newest flow regulatory structure on the western edge of the park. Work began in earnest at the beginning of 2021 on the five-million-gallon water tank and it’s expected to wrap up next month.
