Provider briefing
How this utility’s billing works
Parker Water & Sanitation District operates as a public water authority serving Parker and surrounding southeastern Denver-metro service area, including portions of Lone Tree and Castle Pines. 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 tiers with fixed monthly charges. Effective January 1, 2026, residential water has a $35.02 monthly water service fee, a $4.50 long-term water fee, Tier 1 at $2.72 per 1,000 gallons for the first 6,000 gallons, Tier 2 at $5.31 per 1,000 gallons through 18,000 gallons, and Tier 3 at $10.95 per 1,000 gallons above 18,000 gallons. Location-specific stormwater and payment-in-lieu-of-tax charges may also apply.. Bills are generated monthly. pwsd says statements are issued around the 7th and the billed balance must be received by the last day of the month in which it was billed., and a typical residential cost reference is PWSD's 2026 budget gives a representative flow example of 4,200 gallons at $44.86 for water plus a $13.82 sewer service fee, or $58.68 per month before any location-specific stormwater or PILT charges. Its rate-history estimate for a typical residential usage pattern is about $1,740.42 annually in 2026, or roughly $145.04 per month including water and sewer usage assumptions.. 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
Wastewater has a $13.82 monthly service fee and a 2026 usage rate of $10.68 per 1,000 gallons. The usage factor uses the account's Winter Quarter Average, calculated from December, January, and February consumption, or actual metered use when lower; the District Manager may authorize an alternate calculation for exceptional or non-conforming circumstances. PWSD describes the methodology as WQA or actual consumption, whichever is less.
Meter and infrastructure notes
PWSD is upgrading homes from walk-by collection to automated meter reading. A radio-frequency remote transmits the meter reading to a receiver in a PWSD vehicle, which transfers the reading into the utility billing system for statement generation; the upgrade eliminates the need to access the property monthly and avoids walking house-to-house. Bills are issued monthly, but the public FAQ does not give a single fixed meter-read calendar date for every address.
