Abstract: This paper describes the design of an inexpensive system for controlling combined sewer overflows using on-site equipment (raingauges, flow gauges, automatic gates, and microcomputers). The system is based on the Timex/Sinclair 1000 microcomputer. An interface was designed for the computer converting it into a real-time data acquisition system and controller. Software for the controller was written in BASIC, and includes data acquisition and storage routines, data processing, runoff forecasting, and control routines. In order to evaluate the system’s effectiveness in reducing the impacts of combined sewer overflows on local receiving waters, the control software was also incorporated in the PCSWMM3 model.
