About Your Sewer Bill

About Your Sewer Bill from Pima County Wastewater Charges


Your sewer charge is determined by Pima County Regional Wastewater Reclamation Department.   They have contracted with Tucson Water Dept to mail their bills.

The sewer bill is based on an average water usage taken from the months of December, January, and February.  They calculate the new sewer fees based on the winter water use each July.  If there is no winter water use recorded then the class average is applied to the account until there is an established winter water use.

The sewer fees are recalculated every July.  They send an insert with the July bill to remind their customers that there is a sixty-day period to apply for an appeal.  If December, January, and February are not the three lowest consecutive months of water usage in the fiscal year (July 1 through June 30) then submit an appeal using the online form or contact Pima County’s customer service at (520) 724-6609. Appeals can also be mailed, faxed, or emailed; instructions can be found on the online form at: https://www.pima.gov/1778/Appeal-on-Winter-Quarter-Average

All questions and inquiries about your sewer charge should be directed to Pima County Regional Wastewater Reclamation Department at 520-724-6609 or go to their website. http://webcms.pima.gov/government/wastewaterreclamation/
