San Marcos and Vallecitos partnered on the new project to encourage water conservation. Five hydration stations have been installed in San Marcos parks to facilitate easy refilling of reusable bottles during outdoor activities instead of using purchased bottled water. Both the City of San Marcos and the Vallecitos Water District are committed to reducing single-use plastics. Each station features a quick-fill mechanism to encourage reusable water bottle use alongside a regular water fountain spout.
