The approximate date the surcharge is expected to become effective is April of 2023.

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.

Rose Valley Water has no arsenic treatment systems.

There is one booster station for the water distribution system that consists of:

  • 4-15 hp booster pumps. The motors of these pumps are replaced every 1-2 years due to inefficient design of inlet and outlet piping.
  • 2-125 hp booster pumps. These pumps were installed in 1999. One of these pumps was rehabbed in 2016.  No major work done to the other pump.
  • 1-10,000 gallon pressure tank. 

There is one reservoir site for the water system that consists of three (3) 400,000 gallon storage tanks. These tanks were constructed in 1999 and are maintained as needed.

There is one current interconnect with the City of Peoria which would only be used in cases of emergency when one of Rose Valley’s wells was to go out for more than two days during peak water demands during the summer.
