2021 Residential Water Rates

New water rates start Jan. 1

The Denver Board of Water Commissioners has adopted rate changes to help pay for its new Lead Reduction Program that launched in January 2020. Denver Water’s rates are designed to pay for critical upgrades and projects to keep its system operating efficiently. The rate change for the Lead Reduction Program will take effect Jan. 1, 2021, and will increase monthly bills for most residents by less than 70 cents if they use water at similar volumes to 2020.

When the new rates take effect Jan. 1, 2021, all residential customers will see a slight increase in both the fixed monthly charge and the price per gallon of water. Inside Denver, a customer using 102,000 gallons as they did in 2020 would see an overall rise in the monthly bill of 67 cents. Customers outside the city using that volume would see a monthly increase between 45 cents and 54 cents per month under an agreement between Denver Water and its suburban distributor partners for 2021 to share costs associated with the Lead Reduction Program.

A water bill is comprised of a fixed charge that helps ensure Denver Water has a stable revenue stream to continue the necessary water system upgrades. The fixed monthly charge, which is tied to meter size, is increasing slightly to ensure Denver Water is recovering 20% of its revenue from fixed charges; doing so helps even out revenues over the year.

Denver Water’s rate structure also includes a three-tiered charge for water use (called the volume rate). To keep water affordable, indoor water use — like for bathing, cooking and flushing toilets — is charged at the lowest rate. Essential indoor water use is determined by averaging the customer’s monthly water use on bills dated from January through March each year. This is called average winter consumption. Water use above the average winter consumption — typically for outdoor watering — is charged at a higher price.

Notes

  1. Applicability: See Chapter 2 of Denver Water's Operating Rules
  2. Payment: Bills are due and payable to Denver Water upon issuance. Monthly bills are delinquent 20 days after the billing date. Late charges will be assessed per Denver Water policy.
  3. Single Family AWC: A customer's average winter consumption (AWC) is used to determine the tier 1 threshold. The AWC is calculated by averaging each customer’s billed monthly water use from January through March, which is a way of determining essential indoor water use. Denver Water has set the tier 1 minimum threshold at 5,000 gallons. and a maximum of 15,000 gallons. For example, if the customer's AWC is less than 5,000 gallons, tier 1 is 0 to 5,000 gallons. If the AWC is over 15,000 gallons, tier 1 is 0 to 15,000 gallons. Volume rates are applied to billed monthly usage.
