The fees vary depending on the Capacity Class chosen. Refer to the New Water and Sewer Service Rates Chart below:

We get this question a lot: “My friend in Temecula (or San Diego, or any other urban area) has a water bill that is lower than mine.   Why are RMWD’s fixed water fees higher than theirs?”  It is a valid question for which there is no simple answer.  Here are some of the reasons our rate structure is different than other areas:
