2021 Residential Rate Tiers

Aurora Water will have a new residential water rate tier structure beginning in 2021.

Affordability, especially regarding water for the life, health and safety of our community, is a priority any time a rate change is being considered.

With the current three-tier rate structure, when Aurora Water incurs higher costs, all customers pay higher rates. By lowering the upper limit of usage in Tier 1 from 20 thousand gallons down to five thousand gallons, we have the ability to spread the additional costs to higher-usage customers who are using more of the water system capacity. Low-usage customers will continue to pay the lower rate.

New Aurora Water Residential Rate Structure (2021)
