Sustainable September SaMo Tour of Sustainable Water Infrastructure Project

Sustainable September 2025 Event

There are only 20 spots available for a unique and educational walk through tour of Santa Monica's SWIP led by Sunny Wang, Santa Monica's Water Utilities Manager. Ask questions, learn about the first underground water treatment facility in the country and the steps Santa Monica is taking toward water self-sufficiency.

The City of Santa Monica SWIP reduces the city’s traditional reliance on costly imported freshwater resources from Northern California and the Colorado River by creating new, local water supplies. It is one of only four international projects nominated for a Global Water Award, a recognition of excellence across the entire international water industry.

The project is an advanced treatment water recycling plant that treats the city’s municipal wastewater, stormwater (wet-weather), and urban runoff (dry-weather) with the new stormwater harvesting tank. Otherwise, the stormwater is discharged into Santa Monica Bay. Once treated, the advanced treated water is conveyed through the existing distribution system and reused for landscape irrigation. The system also allows for excess produced water to be recharged into the groundwater supplies and extracted later for reuse as a local and sustainable drinking water supply.
