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:

To determine the exact static water pressure at your property, you can…
