ABSTRACT
This chapter examines urban stormwater control and treatment technology leading to the feasibility of urban stormwater reuse for various purposes, including industrial cooling and process, irrigation, and recreational water supply. It presents a hypothetical case study illustrating the cost-effectiveness of reclaiming urban stormwater for complete industrial supply. The chapter describes treatment processes using test data obtained from stormwater control demonstration projects supported by the Environmental Protection Agency’s Office of Research and Development Storm and Combined Sewer Overflow Pollution Control Program. The reported stormwater quality parameters vary considerably in concentration and mass. Storm runoff volume and flow rate vary greatly as well. Many unit processes designed for treatment of water and wastewater can be adopted to stormwater treatment. Systems for urban stormwater reclamation may include storage and pretreatment, secondary treatment, and advanced treatment processes. Disinfection of urban stormwater is generally practiced at treatment facilities to control pathogenic microorganisms.
