A system is disclosed for monitoring the use of water in an individual unit of a multi-unit building wherein the multi-unit building is supplied water from a common source and the individual unit has a plurality of water consuming structures each supplied by one or a pair of water pipes supplied from the common source. A monitor determines the volumetric flow through each of the pipes, each of said monitors and periodically transmits a signal encoded with the volumetric flow of the pipe and the identification of the individual unit in which the pipe is located. A remote receiver receives the encoded signals from each of the monitors and computes a total volumetric flow of water for the individual unit for a selected period of time. Additionally, continuous volumetric flow through the pipe proximate the water consuming structure during a predetermined period of time can be predetermined time so that an alarm signal can be transmitted in the event that it is determined that flow to the water consuming structure has been continuous for the predetermined time. The use of heat energy in the water devices can be monitored to define the heat energy use. A remote receiver receives the encoded signals from each of the monitors, defines a total volumetric flow of water and /or total heat energy use for the individual unit for a selected period of time, computes a water consumption/heat energy charge and prepares and forwards a bill to the individual unit.
