SEWER OVERFLOW DISCHARGE MONITORING SYSTEM AND METHOD

摘要

A method and a system for monitoring the performance of combined sewer overflow structures is described. The inventive system includes sensors for monitoring the level of sewage in the structure and the operation of valves. A data processing unit collects data and calculates the flow of an overflow event and/or the performance of gate valves. The system may be battery operated and may adaptively change the sensor sampling time to prolong battery lifetime.

1. A system to monitor the operation of one or more gate valves operating in parallel between an upstream sewer location and a downstream sewer location, the system comprising:
sensors for generating measurements of an upstream liquid level at an upstream sewer location, a downstream liquid level at a downstream sewer location, and an indication of the degree of opening of each of the one or more gate valves; and a data processing device to sample the measurements and programmed to estimate the volume of sewer discharge from the sampled measurements.
