A significant ongoing problem throughout the state haws been periodic overflows of raw sewage onto streets, streams, and into coastal waters. Overflow problems are often caused by uniformed sewer users discharging extraneous substances and rainwater that cause clogging, malfunctions, or overloading of sewage collection systems. Major spills can result in closure of beaches and hazards to public health. Besides public health risks associated with pathogens, sewage spills can result in discharge of excessive nutrients into receiving waters.
Objectives/Goals: To develop a Public Service Announcement (PSA) to educate the public about the causes of sewage spills, the impacts of sewage spills to public health and the associated monetary costs to sewer users, and the important role of the public in minimizing the occurrence of sewage spills.
