Provider briefing
How this utility’s billing works
Parker Water & Sanitation District operates as a public water authority serving Parker, Lone Tree, Castle Pines, and portions of unincorporated Douglas County. Customers should use the provider’s current account-specific bill and official customer-service instructions as the final authority for deadlines, balances, and service requests.
The published water-rate framework is described as Increasing-block residential water rates plus fixed monthly water and long-term-resource fees. Effective January 1, 2026, the residential schedule is $35.02 water service, $4.50 long-term water, $2.72 per 1,000 gallons for the first 6,000 gallons, $5.31 for additional use through 18,000 gallons, and $10.95 above 18,000. Wastewater usage is calculated using the first tier of metered use or the account’s winter average, whichever is lower.. Bills are generated monthly. pwsd issues bills around the 7th of each month, and payment for the billed balance is due by the last day of the month in which it was billed., and a typical residential cost reference is At 6,000 gallons per month, the 2026 residential water portion is approximately $35.02 + $4.50 + (6 x $2.72) = $55.84. PWSD’s wastewater service fee and usage rate vary by the 2026 schedule, service area, winter-average factor, PILT, and stormwater collection, so a verified complete household total is not publicly stated in this record rather than estimated from an incomplete rate extraction.. These descriptions are useful planning benchmarks; actual charges can change with meter size, usage, sewer averaging, local taxes, drought stages, or account-specific fees.
Wastewater and sewer calculation
PWSD calculates wastewater usage using the lesser of first-tier metered water usage or the account’s Winter Average, which is based on December, January, and February consumption or an approved alternate calculation for non-conforming cases. Bills may also include fixed wastewater service, stormwater fees collected for the Town of Parker, and PILT fees for certain out-of-district customers.
Meter and infrastructure notes
PWSD bills from a monthly measured-consumption period and its new customer portal provides real-time water-usage tracking and leak alerts. The reviewed pages do not identify the exact meter hardware or radio-transmission interval; wastewater calculations use monthly readings and winter-average logic.
