The first tier in Denver Water’s rate structure is for essential indoor water use, which is charged at the lowest rate. We calculate this 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.
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 is more than 15,000 gallons, your Tier 1 range is 0-15. If it’s between 5,000-15,000 gallons, your Tier 1 range is 0 to the average winter consumption on your bill. 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.
