Overview of Billing Components
Rates and Charges
PCWA sets treated water rates to cover the costs of providing water service. PCWA is required to maintain the treatment, transmission, storage, and distribution facilities for properties that have paid Water Connection Charges, regardless of usage. Monthly charges for treated water service for each customer will vary depending upon meter size, volume of water used, and customer classification.
Water Rate Structure
PCWA's water rates include a fixed charge, a renewal and replacement charge, and a commodity charge:
- Monthly Fixed Charge - Covers operational costs, including personnel, supplies, services, state and federal mandates, purchased water, insurance, legal and consulting services, utilities, routine capital, and other operational expenses. For treated water, the rate is based on meter size. For untreated water, the rate is flat.
- Renewal and Replacement Charge - Funds improvements for aging infrastructure, such as water treatment plants, pipelines, canals, and other water system facilities. For treated water, the rate is based on meter size for meters up to 8 inches or on Units of Capacity for meters 8 inches and larger. (One Unit of Capacity is equivalent to 1,150 gallons per day.) For untreated water, the rate is flat.
- Commodity Charge - For treated water, tiered rates are based on the amount of water used. For untreated water, rates are based on an orifice size measured in miner's inches.
Note: Fixed charges apply even if no water is used and are prorated based on the number of days in the billing period.
