2023 Aurora Water Rate Information

Like many things in life, the cost of treating and delivering water is being affected by inflation. We’re also seeing greater cost to maintain and improve our system to ensure reliability as it continues to age.  For 2023, water rates will have an overall increase of 4%, while sewer rates will go up by 5% and storm drain fees will go up by 3.5%. Residential water tiers were modified in 2021 to promote affordability and conservation with no change to the Tier I rate.

For the average residential customers in Aurora, the total monthly impact of these rates on your total bill will average about $3.75. These new rates take effect on January 1, 2023, and will be prorated on your bill. You will see two sets of charges in January, one dividing your bill proportionately for 2022 and the other for 2023, dependent on when your water meter was read.
