There are over 775 combined sewer systems (CSS) nationwide located in the Mid-Atlantic, Northeast, and Midwest portions of the country, many developed before 1900.  These antiquated systems convey sanitary sewerage AND stormwater in one piping system.   ln dry weather, the system delivers wastewater (sewerage) to wastewater treatment plants.  ln wet weather, rain water also enters the system, and, if the conveyance capacity of the system is exceeded, the excess flow spills into the local rivers and waterways carrying trash, debris and pollution with it.  This discharge is called Combined Sewer Overflow (CSO).   Trash, debris, and pollution that has been washed into the combined sewer system infrastructure must be separated out of the sewerage prior to treatment at the wastewater treatment plants.  This separation process is very expensive and creates public health issues related to disposal of the hazardous contaminated trash.

Installing Amy’s patented Child Safety and Curb Inlet Protection Guard as a pre-treatment device would help reduce municipal costs by many millions of dollars every year due to the immediate reduction of trash and pollution to the over-burdened separation processes prior to treating the sewerage at wastewater treatment plants.  In addition, storm drain overflows loaded with trash, debris, and pollution into the local rivers and waterways would see an immediate reduction.  Clogged storm drains would become a limited potential nationwide.  Public health issues could be minimized with the significant reduction in hazardous contaminated trash.
