The Pima County Board of Supervisors plans to resurrect its discussion of a potential increase to residential sewer rates at Tuesdayβs meeting.
The board has delayed voting on a rate hike three times since county wastewater officials first proposed an increase in January.
The proposal on the table for Tuesday would add nearly $3 per month to average ratepayerβs bill.
The proposal includes a 3 percent rate increase beginning this year that is estimated to generate an additional $400,000 in revenue for Pima County.
If approved, the rate increases would go into effect in July and again in July 2016. The average monthly bill would climb to $42.03 with the rate change.
A second 3 percent hike in 2016 is also scheduled for discussion, which would increase the average bill to $43.29 if approved.
The estimated average residential wastewater customer currently pays $40.81 per month.
A report compiled for the Water Infrastructure Finance Authority of Arizona in October showed the average monthly residential wastewater bill in the state was $34.95.
Pima County last increased rates in 2013. At that time, the average residential bill was $37.48.
Sewer rates have been increased most years over the past decade, more than doubling in that time.
In 2005, the average residential sewer bill was $15.16, according to county documents.
Supervisors also plan to discuss possible connection-fee increases.
Those proposed increases would bring the cost of connecting into the sewer system to $4,188, up from $4,066 currently.
An increase to connection fees is not scheduled for a vote on Tuesday, however. The issue must first be discussed by the Regional Wastewater Reclamation Advisory Committee and then scheduled for a public hearing before the Board of Supervisors.
No dates have been set.
