Tier 4 Exemption Program

Tier Four Exemption is an incentive program designed to help you save water and lower your bill. To qualify, you must meet the district's current water conservation standards and pass a verification site visit. Your property then becomes exempt from Tier Four water rates for a two-year period. This means your water will be billed at no higher than Tier Three Rates.

For more information about the program and how to apply, please email the Water Conservation Department or call 415-945-1520.
