The publication is the final report of a demonstration project to apply sewer system monitoring and remote control techniques to reduce pollution of receiving waters from combined sewer overflows and storm wastewater pumping. The monitoring system includes telemetering rain gages, sewer level sensors and overflow sensors and a central computer and data logging facility. Wastewater pump stations and certain key regulators were remotely controlled to allow in-system storage. Remotely controlled sluice gates were installed in a sewer to study the feasibility of using dry weather flow to flush sewers. The report includes a detailed discussion and evaluation of the monitoring and remote control equipment, installation details, the concept of the monitoring and remote control equipment, installation details, the concept of in-system storage, and the operation of the system based on an 18-month study period. Detroit has found that many of the larger sewers are not used to capacity during storms. Utilization of system monitoring and remote control techniques has resulted in a significant reduction in the volume of combined sewer overflows and storm wastewater pumping as well as reduced operation and maintenance costs.
