Ratemaking is a formal regulatory process by which public utilities set the prices that they charge to customers. Rose Valley Water is regulated by the Arizona Corporation Commission (ACC) and it is the entity who will determine how much of the requested increase in rates will be approved. 

It takes an average time of six (6) to twelve (12) months to complete a rate case.

The average residential customer will see an increase of approximately $12.00 on their monthly bill.

Rates for water service can vary widely between companies based on the number of connections, the complexity of the infrastructure and the specific operation costs of a given water system.  That is why the ACC regulatory process is so important. The ACC analyses the data, listens to consumer comments, and ultimately sets rates that they feel are necessary for the company to remain viable and provide you, the consumer, with reliable and safe water.

Our first use of funds is to provide safe and reliable water. With that in mind, we will assess our system’s mechanical components at the time of approval to determine what, if any, upkeep or maintenance issues need to be addressed. Our main areas of concern are making improvements to the systems operating software, major water tank maintenance, water meter upgrades, and water tank level controller improvements.

Yes, our water is safe. Regular water testing is mandated by Arizona Department of Environmental Quality (ADEQ). ADEQ requires water utilities to test for a number of contaminants to ensure that your tap water is safe. The annual results of the testing are compiled into a document titled the Consumer Confidence Report (CCR). Rose Valley Water’s CCR’s are available on the website for your review. We also chlorinate our water to provide you with another level of protection.
