Your average winter consumption

The first tier in Denver Water’s rate structure, which is charged at the lowest rate, is for essential indoor water use. But how much water is used indoors will be unique to each household.

We calculate your first tier using your monthly water consumption and the number of days in the billing period for bills dated in January, February and March.

This is your average winter consumption, and it is recalculated each year. You can find it on your bill just above the “billing period” line.

For residential customers, the minimum allowance for the first tier is 5,000 gallons and the maximum is 15,000 gallons.

  • If your average winter consumption is less than 5,000 gallons, your Tier 1 range is shown on the bill as 0-5.
  • If it’s between 5,000-15,000 gallons, your Tier 1 range is 0 to your average winter consumption shown on your bill.
  • If it is more than 15,000 gallons, your Tier 1 range is 0-15.

For example, if your average winter consumption is 7,000 gallons, your Tier 1 range is 0-7.

If your Tier 1 is 0-5, and you use less than 5,000 gallons, you will only be charged for the amount of water used during that billing period.
