CSA 7 customers are billed quarterly based upon meter readings for the preceding 90 days.  The bill is comprised of a “Service Charge” and a “Volume Charge” component. The Service Charge is a flat monthly charge designed to recover costs that do not vary with consumption, such as, meter reading and billing and maintenance of the distribution system. The “Volume” charge is based on the amount of water used. One unit (100 cubic feet) equals 748 gallons.
