Billing and account research from public material
Provider-specific research notes are displayed separately from fields that contain only an unavailable-information marker. Read qualifiers in each note and verify current account terms with the provider.
- Billing frequency
- Monthly. Water meters are read during the first three days of each month, bills are generated and mailed between the 6th and 9th, and payments are due on the last business day of the month.
- Rate structure
- Individualized water-budget tiers with fixed monthly service charges. Tier 1 covers the account’s indoor Average Winter Monthly Consumption (AWMC), Tier 2 is the April–October irrigation-season allocation, and Tier 3 is usage above the total budget; rates increase progressively by tier. A conservation surcharge applies to single-family residential usage above 40,000 gallons.
- Residential cost reference
- For a new single-family account before an individualized AWMC is established, the Town assigns a 4,000-gallon class average and states that the monthly wastewater charge is approximately $35; the total water bill depends on the 2026 fixed charges, individualized budget, and usage tier. A reliable 5,000–7,000-gallon total should be calculated in the Town’s current 2026 rate PDF/portal because outdoor allocation and property-specific budget change the result.
- Wastewater and sewer calculation
- Castle Rock calculates the wastewater component from the customer’s Average Winter Monthly Consumption, averaging indoor potable use from November through February. The AWMC is reset on the April statement and represents the monthly wastewater volume treated; the wastewater charge remains stable through the year unless the annual AWMC changes. New customers receive a 4,000-gallon class average until enough history exists.
- Meter reading
- Castle Rock reads all water meters for actual usage during the first three days of each month. The reviewed public pages do not identify AMR/AMI technology; the billing portal provides usage tracking and graphs against the individualized water budget.
- New-account deposit
- The reviewed current Castle Rock Water customer-service and rate pages do not publish a standard residential startup deposit or credit-check waiver. New homeowners generally receive a first bill after title-company transfer, while renters’ service arrangements are coordinated through the landlord.
- Activation or transfer fee
- No current 2026 residential account activation or transfer fee was published on the reviewed Castle Rock pages. Property transfers use title-company or rental-property forms, and the first statement establishes the account portal.
