Every month, each customer receives a calculated “water budget” that represents an efficient volume of water that meets his or her individualized water needs. There are five customer classes:
Single-Family & Multi-Family Residential Customers
Total Household water budget = Indoor water budget + Outdoor water budget. All water used by a residential or multi-family customer within his or her calculated indoor water budget is billed at the Tier 1 rate and outdoor water budget is billed at the Tier 2 rate.
Public Spaces Irrigation Customers:
Total water budget = Irrigable area (square footage per parcel) x Evapotranspiration x 1.0 plant factor x 0.62 / 748 (conversion factor to calculate budget in HCF). All water used by a public spaces irrigation customer within his or her calculated outdoor water budget is billed at the Tier 1 rate.
Recycled Water Customers:
Total water budget = Irrigable area (square footage per parcel) x Evapotranspiration x 0.8 plant factor x 0.62 / 748 (conversion factor to calculate budget in HCF). All water used by a recycled water customer within his or her calculated outdoor water budget is billed at the Tier 1 rate.
Irrigation Customers:
Total water budget = Irrigable area (square footage per parcel) x Evapotranspiration x 0.7 plant factor x 0.62 / 748 (conversion factor to calculate budget in HCF). All water used by an irrigation customer within his or her calculated outdoor water budget is billed at the Tier 1 rate.
Commercial Customers:
Total water budget = Calculated as a three-year rolling average of daily water use for the respective billing cycle. All water used by a commercial customer within his or her calculated water budget is billed at the Tier 1 rate.
