Water Rates
The District developed the water rate structure to encourage efficient use of water and discourage waste by providing users a water budget allocation suited to their specific needs. The tiers in the water budget rates are defined individually for each customer as shown.
There is a possibility of a water rate increase of 8% in 2012, 2013 and 2014. The proposed rate increases are subject to board approval.
Water Quality Fee ($/ccf*): $ 0.20

Water Budgets
According to American Water Works Association, "water budgets are volumetric allotments of water to customers based on customer-specific characteristics and conservative resource standards." After completing a thorough study the District implemented the following approach to determine individual water budgets for each customer in the defined customer classes.
| Single-Family Residential ("SFR") & Multi-Family Residential ("MFR") |
| Allocation Equation: SFR - Indoor + Outdoor MFR - 3-yr historical montly average |

For residential customers, the indoor allocation is based on an average of 4 occupants per home providing an allotment of 60 gallons per capita per day (GPCD). Adjustments for additional occupants can be requested by submitting an Adjustment Application (or Variance) to the District. These applications may be obtained from the District office or website and will require supporting documentation and approval.
The outdoor allocation is based on irrigable area (“IA”) determined by the total square footage of the parcel from assessor’s data and the amount of water required to maintain a healthy landscape. For residential customers, the irrigable area is estimated to be 45 percent of the total parcel area. For irrigation only customers, the irrigable area is assumed to be 100 percent of total parcel area.
The amount of water needed for irrigation is based on:
- Weather: determined by evapotranspiration (ET0) data gathered from a local weather station
- Landscape factor: the State of California Code of Regulations Title 23, Section 491 provides a landscape factor ("LF") adjustment of 70 percent to the amount of water needed for irrigation to encourage conservation
- Conservation factor: approved by District Board to account for water supply shortages (currently set at 100%)
To calculate the customer-specific monthly water budget allocation, the following equations can be used:
- Indoor allocation = GPCD * Household Size * Days per billing cycle / (748 gallons/ccf)
- Outdoor allocation = (ET0/(12in/ft))* IA * LF * conservation factor / (100 ft3 / 1 ccf)
The tiers for non-residential customers will be revised when the Board declares a water supply emergency and mandatory cutbacks in water usage.

Elevation Zones
In November of 2000, the District established a surcharge to pass on the increased costs of delivering water to customers in higher elevation zones. This surcharge continues under the current rate structure.
The District is divided into four (4) elevation service zones, as shown on the Zone map below. The northern most area is defined as the "Base Area", while moving south the Zone structure includes "Area 1", "Area 2", and "Area 3". If you are in Areas A1, A2, or A3, you will be charged an elevation booster surcharge based on the water units you use ($/ccf) as shown in the preceding tables.
These charges are based on the actual pumping costs and are re-evaluated every five years.
