David, Here is my April water bill from the City of San Clemente:Here's my answer: You don't need to modify your behavior. Even better, your bill is about 12 percent variable and 88 percent fixed. That means that your revenue pattern is very closely matched with San Clemente's cost pattern, a goal that I supported here.
Water base fee $8.38
Water consumption 6.52 (4 units Tier 1 @$1.63)
Sewer base fee 18.30
Sewer commodity 11.50
Storm drain 2.96
Clean ocean fee 5.02
So the question for today is this; How much higher will the $1.63 consumption price have to rise before, I, or anyone, will make serious changes in behavior vis-a-vis what ever they are doing today?
Bottom Line: Those who are already using water wisely (JWT and wife used 100 gal/day, which is way below the SoCal average of 100+gal/day/capita) do not need to modify their behavior.
