I used to receive one bill for water and sewer. Why do I get two bills now?

How much do you charge for sewer services?  
The Town of Sahuarita Wastewater Utility sewer charges are recalculated annually, beginning with each July service period. The total monthly charge is comprised of an administrative fee and a water consumption fee. The administrative fee is $14.39. The consumption fee is $4.80 per 100 cubic feet of water consumed. Commercial accounts may require a multiplier to the consumption fee, depending on the nature of the business conducted. A table of factors is provided in the Sahuarita Town Code (STC) §13.10.200. 

How do you determine how much water I consumed? 
The Sahuarita Water Company provides the Town with each account’s monthly water consumption figures (in thousands of gallons) for the prior year. The data is used to derive a monthly average for the year and a monthly average during the winter months (December, January, and February), which are typically the lowest usage months for the average customer. The lower of the two averages is used. For residences, the system average of 700 cubic feet (7 CCF) is used if an account doesn’t have sufficient history on which to calculate an average.    

My water bills are calculated in thousands of gallons but my sewer bills use hundreds of cubic feet.  How do you convert this?
 1000 gallons is equivalent to 134 cubic feet (="1.34" CCF). 

Why isn’t my bill based on exactly what goes down my drain each month?
Sewer meters that can measure the exact volume of wastewater you send down the drain would be extraordinarily expensive to install, maintain and monitor. Such meters are used only with industrial-strength wastewater dischargers. Averaging is a method that is used nationwide to calculate sewer bills.

How can I appeal my sewer bill?
The sewer fees are recalculated every July. Under the Town’s Code, customers have 60 days after the mailing of the July service period bill to appeal the updated sewer volume rates. If you did not reside at the property prior to December 31, your sewer volume rate cannot be appealed. To make an appeal, you will need to complete a form, which can be found on our website at http://sahuaritaaz.gov/FormCenter or by contacting us.

What is the service period for a sewer bill? 
The service period is the month in which sewer/wastewater services are provided to our customers. Bills are sent the following month, in arrears.  For example, a bill sent in September will be for the August service period.

How many days will I have to pay my sewer bill?

You will have at least 20 days after the date the bill was printed to pay. Bills are sent out the first business day of the month and due the 25th of the same month. For example, a bill sent 8/1/16 will be due 8/25/16.

How much do I owe?
The amount reflected on your billing statement is the amount owed as of the billing date. A balance due in parentheses represents a credit balance. If your balance due amount is in parentheses you do not need to send payment. If a payment was received after the due date it may not be reflected on your statement. However, you can log into the MuniBilling system and see any payments that were received and applied to your account after the billing date.

I have a past due amount on my sewer bill, are there payment plan options?

Yes, the Town of Sahuarita Wastewater Utility has payment plan options available to sewer customers with a delinquent balance. Please call the Town of Sahuarita Wastewater Utility at 520-344-7101 or email 
to request additional information.

Are there any financial assistance programs?
There are programs that provide assistance to qualifying individuals. You may call the Arizona Department of Economic Security at 1-800-582-5706 for information on eligibility and application requirements. They can also help you locate other agencies and programs in our area.

Do you offer a vacancy rate?
No. Due to recently approved changes to the Town's Wastewater Code, vacancy rates are no longer being offered. Beginning with the January 2018 service period (February bill), monthly fees will be based upon actual water consumed in the month instead of using the prior year's winter/annual average. 

Why is my sewer bill higher than my water bill?
Potable (drinking) water delivered to homes and businesses comes from surface water provided by the Central Arizona Project or from ground water. These natural and relatively clean water resources require some treatment before they are delivered to customers. After the water is used, it becomes "wastewater," which requires a much higher and costly level of treatment. This water eventually is returned to the environment and must be cleaned so it doesn't harm plants, animals or people.
