Wastewater billing FAQs

Will sewer rates increase?

No, the rates will not increase for FY 18-19.  The City Council authorized a rate study in the FY 18-19 budget process.  This rate study will analyze any need for rate changes after FY 18-19. 

How high will rates rise?
Rate studies will be conducted every five to seven years but future increases are expected to be more modest than 2018's 4 percent as the city moves closer to having the wastewater debt retired in 2027. Our goal is to keep rates low while providing the expected level of service. 

Why isn’t my bill tied to my water usage?
For residential customers, sewer bills are set at a flat rate.  Because the City of Sedona does not purvey water, and the water distribution system is owned and managed by private water companies, the city does not have ready access to your water usage data.  

Does the wastewater system generate a profit?
No.  The system is owned by the rate payers and rates are set as necessary to cover costs.  The system generates no profit and provides no financial support for non-wastewater activities.  

Why do rates continue to increase?
 Sewer rates in Sedona did not increase for almost 14 years, from 1997 and 2010.  When formal rate studies were completed in 2010 and 2013, fee increases were necessary to meet the financial obligations to operate, maintain, upgrade and expand the wastewater system.  

Self Sufficiency:  The City is moving toward a self-sufficient wastewater system that operates like its own “enterprise” business, where users cover all costs through the sewer rates charged.  This model is used by most public utilities across the nation and is required by Arizona Revised Statutes.  The wastewater system’s dependence on subsidy by the City sales tax is being reduced.  As sewer rates are increased, the City decreases the sales tax subsidy.  This enables the City to use the sales tax towards fixing roads and completing other capital projects throughout the city.  

What will be the increase to my monthly rate?
The last increase of 4% was effective July 1, 2017.  There will be no increase on July 1, 2018.  

The current residential monthly rates are:

Per residential unit (ERU) - $61.11

Low-flow rate - $47.52

Low-income residential rate - $32.17

Are there any programs in place to help residents who can’t afford the monthly fees?
Yes.  Qualified low-income residents can receive a nearly 50% percent discount on their wastewater bill. To learn more and find out if you qualify, visit the “Wastewater Utility Billing Services” tab of the “Wastewater Department” page of the City’s website.  

Why are my rates different from other communities?
Comparisons of monthly sewer service charges among different communities vary greatly depending on a number of factors including:

Age of wastewater system. The city system was constructed recently and in a relatively short time due to State mandates in the 1980s. Part of the wastewater bill goes to paying the bonds for the initial construction. The bonds will be paid off in 2027.

Geography of the area served. The wastewater collection system contains 17 pump stations due to the hilly terrain. Pump stations are expensive due to costs for power and maintenance.

Size of system. Sedona’s system services a low-density population many miles away from the treatment facility. This means fewer paying customers and higher fixed costs.

Regulatory requirements. The level of treatment required is specified by the Arizona Department of Environmental Quality. This may differ between communities because of where the water is discharged or how it is used after treatment.

Environmental sustainability. Sedona treats wastewater to an A+ level. Recent improvements also allow the city to inject treated water back to the water table. These activities are critical to ensure adequate water supply in Arizona.  

Why do I have to pay a monthly “standby fee” if I am not connected to the sewer system?
The City constructs sewer system facilities capable of handling all current and likely future customers.  The standby fee is a charge to those in sewer areas that have not yet connected to the constructed system but can in the future.  The fee is for maintenance of that portion of sewer system capacity that was constructed to serve these future connections.  Without the standby fee, all customers currently connected would be paying for their own capacity plus the capacity needed for future customers. 

What is the low-flow residential rate?
Qualified residents can receive a discount of more than 20% on their bill if they meet the low-flow toilet requirements.  All toilets in the residence must be low-flow toilets (not to exceed 1.6 gallons per flush).  For more information, visit the “Wastewater Utility Billing Services” tab of the “Wastewater Department” page of the city’s website.
