Water & Wastewater Rates

Water and Wastewater Rates

The rate structure for water service fees has five customer classes: residential and multi-family, commercial, irrigation, and recycled.  The rate structure is comprised of two components: (1) a fixed monthly service charge (the “Service Charge”); and (2) a variable volumetric water consumption charge (the “Volumetric Charge”). The rates for the fixed monthly Service Charge are established on the basis of the size of the water meter serving a property and are calculated to recover a significant portion of the District’s fixed costs, such as water facility repairs and replacements, meter reading, billing, and customer service. The rates for the variable Volumetric Charge are based on the number of units of water delivered to a property and consist of five tiers which results in  higher rates as the level of water consumption increases (one unit of water equals one hundred cubic feet (“HCF”), or 748 gallons). As described below, each customer is allocated a reasonable amount of water based on that customer’s particular needs. This allocation is referred to as a “water budget.”

Residential Water Rates – Monthly Bills

Residential and multi-family customers are given an indoor and an outdoor water budget based on individual calculations.  Indoor water budgets are calculated using three factors: (1) 60 gallons of water per person per day; (2) the number of people in the household; and (3) the number of days in the billing cycle. Their outdoor water budgets are calculated using 3 factors: (1) the amount of irrigated area per parcel; (2) actual daily plant water loss (“evapotranspiration”); and (3) a “plant factor” of 0.70 that reflects the water needs of specific types of plants that are native to the District’s service area and guidelines provided by State law. All water used by a residential or multi-family customer within his or her calculated indoor and outdoor water budget is billed at the Tier 1 and Tier 2 rates set forth in the tables below.

The Basic Service Charge is a fixed amount based on the meter size at the service address. The most common meter size for residential properties are between 5/8′ and 1″. See your water bill for your meter size. The Consumption or Volumetric Charge is determined by the amount of water served to the property, and is measured in billing units.

 
*One billing unit (BU) equals 748 gallons of water.

Commercial Water Rates, Wastewater Rates & Service Charges – Monthly Bills

Commercial customers’ water budgets are calculated based on a three-year rolling average of each customer’s monthly water use.  All water used by a commercial customer within its calculated water budget is billed at the Tier 1 rates set forth in the tables below.


Irrigation Water Rates & Service Charges

Irrigation water customers’ water budgets are calculated using three factors: (1) the amount of irrigated area per parcel; (2) evapotranspiration; and (3) a plant factor of 0.70, except high foot traffic public space areas with a plant factor of 1.0.  All water used by an irrigation customer within his or her calculated outdoor water budget is billed at the Tier 1 rates set forth in the tables below.


Recycled Water Rates & Service Charges 

Recycled water customers’ water budgets are calculated using three factors: (1) the amount of irrigated area per parcel; (2) evapotranspiration; and (3) a plant factor of 0.80 (due to the public benefit of recycled water), except for high foot traffic public space areas with a plant factor of 1.0.  All water used by a recycled water customer within his or her calculated outdoor water budget is billed at the Tier 1 rates set forth in the tables below.

Wastewater Service Charges

The District is a member agency of the South Orange County Wastewater Authority (“SOCWA”), a joint powers authority comprised of ten governmental agencies.  SOCWA operates four regional treatment plants and two ocean outfalls.  The District contracts with SOCWA to treat and discharge the District’s wastewater.

The rates for the District’s monthly wastewater service charges are structured to meet the District’s costs to operate and maintain its wastewater collection system, and to pay SOCWA for treating, and disposing of its wastewater. The rate structure consists of three customer classes: residential, multi-family, and commercial.  Within the commercial customer class there are four subclasses of customers.   The subclasses are classified based on the type of commercial activity and the constituents that they discharge into the wastewater system.

 

Sewer Classes

Commercial Class 1 – Typical users include: banks, car washes, churches, department and retail stores, laundromats, professional offices, schools and colleges.
