Publication number: 20120315089Abstract: The invention is a system and related method to reduce erosion caused by storm runoff. Eco-friendly erosion reduction assemblies help reduce the effects of both sheet and rill erosion. The assemblies comprise a receptacle housing a perforated water velocity reduction wall embedded in media. The wall may be constructed from recycled tires and the media utilized may be from on-site materials. A series of such assemblies in an erosion zone limits erosion by reducing water velocity.Type: ApplicationFiled: June 8, 2012Publication date: December 13, 2012Inventor: Richard Burns

Patent number: 8328469Abstract: A method of remediation of an athletic field playing surface after a rainfall is disclosed. The method includes the steps of providing a quantity of water absorbing polyacrylate polymer such as potassium polyacrylate, spreading the water absorbing polyacrylate polymer over an area of athletic field playing surface where rainwater has fallen or collected, allowing time for the water absorbing polyacrylate polymer to absorb the rainwater and produce a gel from the combination of the rainwater with the water absorbing polyacrylate polymer, then removing the gel so produced from the athletic field playing surface. The gel or remnants of the gel so produced may also be raked into the dirt of the athletic field.Type: GrantFiled: October 17, 2008Date of Patent: December 11, 2012Inventor: Gregory L. Bonin

Publication number: 20120308311Abstract: An embankment system comprises a source of pressurized sand/concrete slurry and a delivery conduit in fluid communication with the pressurized sand/concrete slurry source. The embankment system further comprises an elongate nozzle having an inlet and an outlet, with the inlet operatively associated with a distal end of the delivery conduit. A tube formed of a sheet material having an open end and a closed end is operatively associated with the nozzle outlet to receive the pressurized sand/concrete slurry through the open end, such that the tube is continuously filled with the pressurized sand/concrete slurry between the closed end and the open end.Type: ApplicationFiled: May 30, 2012Publication date: December 6, 2012Applicant: RAMPART TECHNOLOGIES, INC.Inventor: Richard Ross

Patent number: 8256995Abstract: A system and method are disclosed for the treatment of liquid runoff, such as rainfall, irrigation, and waste or produced water, utilizing aboveground, modular, permeable barriers containing reactive media that can immobilize particular solutes of concern, removing them from the liquid runoff. The modular design allows construction of a relatively-uniform barrier, or media volume, that is self-supporting and easily assembled, maintained, modified, and augmented. A permeable reactive barrier constructed according to the present invention provides significant contact between the reactive media and the solutes of concern while allowing the runoff stream to flow through the structure relatively unimpeded.Type: GrantFiled: May 25, 2006Date of Patent: September 4, 2012Inventor: James P.
