Water Supply Permits - Wineries & Businesses
Water supply permits are required by the California Department of Public Health for some businesses that have a well as a water supply. New wineries or other businesses open to the public that use a well as a water supply can benefit from our well yield and pump testing services. Wells drilled in alluvial soils require an 8 hour yield test. Capacity tests for wells drilled in Bedrock formations are more stringent and require a minimum 72 hour yield test.
