Urban Stormwater Control Package for Automated Real-Time Systems

摘要

A methodology is presented for automatic computer control of in-line sewer storage as a cost-effective means of limiting water pollution for storm and combined sewer overflows. The methodology called a Stormwater Control Package (SWCP) involves the application of realistic computer models for inflow forecasting, sewer routing, and operational storage control for real-time simulated environments. Controllable in-line storage uses adjustable weirs, valves, or gates in interceptors, laterals, or outfalls to create backwater that is stored to prevent an overflow of untreated stormwater. Because rapid response is needed to deal with the complex flow characteristics occurring during a storm, automated computer control is needed. The control package is applied to San Francisco's Marina Branch of the North Shore Outfalls Consolidation Project to demonstrate SWCP's potential usefulness.
