Voter-Approved Parker Water & Sanitation District Inclusion

Welcome! This page is where you will find information on the proposed Inclusion (merger) of Castle Pines North Metro District’s water & wastewater utilities, infrastructure, and services with those of the Parker Water & Sanitation District. Check out our monthly water & wastewater bill-conversion calculator at the bottom of this page.

Monthly Water & Wastewater Bill-Conversion Calculator

(Enter two figures into calculator below.)

If properly used, this calculator will help each CPNMD residential customer understand how the proposed Inclusion would impact their respective monthly water and wastewater utility bills.

Our conscientious customer service representatives, Susan and Carol, and our billing manager, Dawne, are standing by at (303) 688-8550 to provide you the two figures you will need to plug into the monthly bill-conversion calculator below.

To use the calculator, CPNMD’s residential customers will need to enter only two figures into the designated fields for each of the last twelve-consecutive months:

  1. Please enter your Total Monthly Water Consumption (in gallons) in the first designated field below.
  2. Please enter your 2020 Wastewater (Sewer) Winter Average Factor (your average monthly winter use in gallons) in the second designated field below.

For each of the last twelve months, assuming you enter the two figures into the calculator correctly, the calculator will automatically compute your Total Estimated Monthly Bill for water & sewer services as it otherwise would have been, under PWSD’s rate structure.

Again, Susan, Carol & Dawne are standing by to help you at (303) 688-8550.



We extend a special thanks to those who participated in the Inclusion-information sessions, which Parker Water & Sanitation District Manager Ron Redd and his fantastic staff hosted for CPNMD residents on June 17, 2021.
