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.

Child sucked into curb inlet

Gaithersburg, MD – When handing out our Child Safety and Patented Curb Inlet Stormwater Protection Guards brochure, the young mother of three started to cry.  Seems several years before, she and her then two children, one 5 and the other 3, were walking down the street.  She was holding the three year old’s hand when the child was knocked off her feet by the rushing water from a neighbor’s swimming pool flush.  The child’s body was pulled into the curb inlet, and was stopped from going all the way in by her head getting stuck in the opening.  It was quite a few scary minutes trying to pull her very frightened child from the curb inlet.

While installing our Guards today, a young child, her sister and Mother walked by on their way home.  The child stopped to say, “Thank you for putting them on.  Now I’ll be safe and my toys won’t fall in.”

Thank You for that wonderful endorsement!!

Following a heavy rain event, the storm drains in the parking garage backed up causing a flood of 3’+ of stormwater, stranding all the parked cars and creating a public health and safety issue.   Our Guards were installed on the curb inlets once the storm drains were vacuumed out to prevent future backups.  It’s been 5 years since our Guards were installed and there have been NO complications or backups in spite of the many heavy rain events and hurricanes we have experienced since then.

I am impressed with the innovative design, especially the elimination of the need to use MD No.2 stone in the curb-line, which is a major source of problems with current curb inlet protection devices”.

High School Riot

December 2009, Montgomery County Public Schools, Division of Construction, Rockville, MD

There was an incident a couple of years ago at a reconstruction project of Northwest High School.  After a football game, a fight broke out and the loose stones used for sediment control became projectile weapons.  Thank God there were no serious injuries to the children or their parents.  The next day, the contractor purchased our patented Sediment Control Guard because it eliminates the need to use MD #2 stone in the curb-line.


Sheriff Raymond Kight

Montgomery County, MD – Sheriff Raymond Kight retired in December 2010 after 24 years of community service.  He ran, with quiet professionalism, the “silent service” of Montgomery County law enforcement.  The Sheriff’s Office primary obligation is to preserve the peace and maintain the public safety.   Sheriff Kight took the later to heart!    The neighborhood kids would call Sheriff Kight when their remote control cars ran beyond reach into the curb inlets!   He would rescue the wayward toys!

“In addition to use as a sediment control device, we have determined that there is also potential for this product to serve as a pre-treatment device to keep debris out of the storm sewer systems and certain stormwater BMPs.  Use of such a pre-treatment device can reduce the costs of long term maintenance of drainage systems, as well as help to maintain the optimal pollutant removal capability of certain water quality BMPs.”

“Why use our Curb Inlet Guard?”  A curb inlet opening is a hazard that could become a liability.  In the attached letter by J. Michael Ellis, “The planners for every municipality, every school district, every sports field or public facility should take a hard look at the injuries that will be prevented and the lives that will be saved if this type of threat is taken more seriously.” As stated in the attached letter by John Small, “Since the inlet guards have been installed in the parking lots, essentially no trash has come in with the storm water.  The guards have provided a near 100% solution to a problem that once seemed to have no workable or economical answer.”

The Child Safety benefits combined with the environmental benefits and cost effectiveness make the installation of this product that much more vital.  Our Guards help prevent children, trash, sediment, chemicals, pollution, pets, rodents/vermin, and hazardous/dangerous items from entering stormwater curb inlets, saving many thousands of dollars every year in storm drain vacuuming and maintenance costs, while helping keep stormwater ponds and our waterways clean.   In addition, stormdrains could have poisonous gasses inside.

We are currently in use by the US Army for their Net Zero Program at Ft Detrick, by DC DOE at King Elementary School in SE, and with M-NCPPC in parks in both PG and Montgomery Counties, as well as many private commercial real estate and HOA’s around the DC metro area.  Our Guards are also used for sediment control, petro/chemical control, and Total Maximum Daily Load (TMDL).
