Sewer / Wastewater Rates Winter Averaging

Pima County Regional Wastewater and Reclamation Department (PCRWRD) uses the average of your December, January and February billing periods to calculate your monthly sewer charge because these three months typically do not have a high outdoor water demand and are considered to be the lowest overall water use.

Because Tucson Water’s billing periods reflect water used in the previous 30-day period, it is possible that some customers water use for the December billing period may capture all or portions of November water use–when irrigation demands may still be higher. PCRWRD offers customers an opportunity to appeal sewer fees calculated using December, January and February billing periods. More information available here.
