Providing safe, reliable wastewater service for our community requires long‑term planning and ongoing investment in the system we all depend on. Like other agencies across California, Monterey One Water is facing rising costs related to delivering wastewater service, including:

▪️ Energy, materials, and workforce investments
▪️ Aging infrastructure in need of repair or replacement
▪️ Complying with evolving state and federal regulatory requirements

To meet these rising costs and continue delivering reliable wastewater service for years to come, M1W has proposed rate changes.
