This page highlights the monthly fees for water and sewer service. To find more information about the development impact fees follow this link.



There is a monthly service charge based on service type and meter size on all accounts. These are collected to ensure the safety of the delivery system and infrastructure. Customers pay these charges regardless of the amount of water used.

No gallons are included in the monthly minimum charges.

Bulk Water/Standpipe Customers

Customers who have bulk water/standpipe accounts used to fill water trucks, etc. have no monthly fee.


To help recover the costs associated with water resources, all water customers are billed the groundwater resources acquisition fee. Similar to the other rates, this rate is calculated based on the monthly usage per 1,000 gallons. The current fee is $0.50 per 1,000 gallons.


There are two taxes levied each month. The sales tax is only charged on the water monthly minimum, water consumption, groundwater resource acquisition fee, and late charges at 10.6%. The Superfund tax is a rate per 1,000 gallons. It is used to ensure water quality per state statute. The tax would be $0.65 for 100,000 gallons, or $0.0065 per 1,000 gallons.


Non-residential customers do not have the tiered billing structure. These customers are billed per 1,000 gallons at the uniform rates listed below.

  • Multi-family, Commercial, Industrial, and Government - $3.82

  • Irrigation, Standpipe/Bulk Water, and Hydrant meter - $4.33


Marana Water uses a tiered, or increasing block, billing structure for residential customers. Based on the monthly meter reading, residential customers are billed for water usage per 1,000 gallons.  As the usage increases, the rate increases.  These types of structures are used to promote water conservation. Click here for an example of the water billing structure.


The Marana Water department requires a refundable security deposit on for all accounts. The deposit amounts are listed below.

Residential property owners - if you are the owner and primary occupant of the property, there is an option to waive the deposit by providing good letters of credit from three previous utilities. These can be sent via fax at (520) 382-2590. If unable to collect these letters, the deposit can be refunded after twelve months of good standing, meaning no disconnects, returned checks, or late fees. 

Tenants and landlords - if you are renting our your home or are renting a home in the Marana Water service area, your deposit is refunded, in full, when you move out or close the account. These deposits must be collected before your scheduled move in date.  


A sewer bill is calculated using two components:

  1. Monthly minimum

  2. Consumption charge

Marana Water has two sewer providers, Marana and Pima County Regional Water Reclamation Department (RWRD), both are collected on the water bill. The example below shows a Marana Water sewer bill with the monthly minimum at $12.63, and the consumption charge of $4.71 per 1,000 gallons.

To calculate the sewer consumption portion of the bill an average of the three winter months, December, January, and February, of the previous year. Every July this average is recalculated for the upcoming year. When calculating the bill, the monthly water use OR the winter average is used to calculate sewer consumption, whichever value is lower will be used.
