"California Sub-Meters completed our sub-metering in the summer of 2007, and what a difference it has made to our Association! Each unit now has its own individual water meter and we have reduced our Association water/sewer bill by over 35% per month. Bi-monthly billing and meter reading is seamless and very user-friendly. In addition, residential water usage costs are fair and equitable now - those that use more, pay more. California Sub-Meters was professional, reliable, and a pleasure to work with."
