Water Providers
Calleguas Municipal Water District supplies water to all public and private agencies within Ventura County. There are four water purveyors serving residents and businesses in the Conejo Valley, and water restrictions may vary among providers.
The City’s water conservation ordinance applies to everyone within the incorporated City of Thousand Oaks, regardless of your service provider. In cases where the restrictions of your service provider do not align with the City’s requirements, you will need to follow the more stringent (stricter) requirements. Residents living in the unincorporated area of the City must abide by the restrictions of their water service provider.
