Water budgets are designed to give customers the water they need for both indoor and outdoor uses. Tiered water rates reward customers who use water efficiently and discourage water waste.
All residential and landscape customers are on a water budget-based tiered rate structure. Each customer’s total water budget includes indoor and outdoor water budgets, in billing units. One (1) billing unit represents 748 gallons of water.
Your Total Water Budget = Indoor Water Budget + Outdoor Water Budget
Indoor water budgets are based on the number of residents in the household, each using 60 gallons
per day. The default single family residential household budget is based on 3 residents, and multifamily
residential is 2 residents. Indoor water budgets may be customized to the specific household size through EMWD’s variance process.
As water is used, billing units are charged the Indoor Use rate until a customer reaches the maximum number of billing units in their indoor water budget.
Outdoor water budgets are based on the amount of water required to maintain a property’s irrigated area as if there was turf grass in that area. The number of billing units will vary every month depending on daily weather information gathered throughout the District’s service area. Therefore, customers will receive more water in the summer for outdoor water budgets than in the winter. Each customer’s estimated irrigated area is listed on their billing statement. Outdoor water budgets may be customized to the specific irrigated area through EMWD’s variance process. Customers with pools, spas, and/or ponds may note that the evaporation rate is approximately equal to the amount of water that turf grass requires, so it is already accounted for in outdoor water budgets.
Once all indoor water budget units are used, billing units are charged the Outdoor Use rate until a customer reaches the maximum number of billing units in their outdoor water budget.
Excessive Use - If a customer exceeds their total (indoor and outdoor) water budget, billing units will be charged at the Excessive rate. The maximum number of billing units in this level is equal to one-half the total
water budget. For example, if the total water budget was 18 billing units (7 billing units for indoor; 11 billing units for outdoor), then the maximum billing units that can be used and charged at the Excessive rate would be 9 billing units.
Wasteful Use - If a customer exceeds the maximum number of billing units in the Excessive tier, all remaining billing units will then be charged at the Wasteful rate. For example, if the total water budget is 18 billing units, the Excessive level is 9 billing units, and a customer uses 36 total billing units, then 9 units would fall into the Wasteful level.

- Outdoor budgets are based on historical weather data within calendar months. Actual budgets WILL vary according to actual weather conditions and actual billing periods. Budget cost estimates apply to the total use of indoor and outdoor water budget billing units only.
- Water budget cost estimates apply to total use of water budget billing units. Customers who use less will pay less.
- The Daily Service Charge rate applies to 1" or smaller meters. Larger meters will be charged higher daily rates.
