Rate Survey

Each year, AMWC performs a survey of the water rates [PDF] used by other water purveyors in San Luis Obispo County.  The average monthly water use for a single-family residence in AMWC’s service area is used for comparison.  The actual average monthly use in other water purveyor’s service areas varies due to costs and/or other conditions.
