This is a very exciting and <br /> unique project. I greatly appreciate the opportunity to assist you with this wastewater <br /> system. Please consider the following information as a summary of the proposed project <br /> implementation and a general overview of how the wastewater treatment system would <br /> be developed and designed. I welcome your input as we continue to move forward. <br /> Hands Four Development Cooperative will create a subsidiary, Hands Four Wastewater <br /> Management, to build and manage a wastewater treatment system from all facilities and <br /> residences in the Fiddlehead Development(project). The currently planned wastewater <br /> system applies a unitary approach throughout the entire project: STEP (septic tank <br /> effluent pumping) systems for primary treatment; the Orenco AdvanTex textile filter <br /> system for secondary treatment; and subsurface drip dispersal systems for final effluent <br /> discharge. This system will be designed and operated under the direction of Agri-Waste <br /> Technology, Inc. (AWT). We have the option of permitting this system through the <br /> traditional County Permitting (with Orange County) or utilizing the Engineered Option <br /> Permit(EOP)private permitting route. Either permitting option is viable for the project. <br /> STEP systems are an attractive contemporary solution to rural primary wastewater <br /> treatment. They can be configured to have one tank per residence (single family home, <br /> for example) or one tank collecting from multiple residences (attached or semi-attached <br /> housing, for example). The effluent from the primary STEP system is sufficiently dilute <br /> after the settling out of solid matter that it can be conveyed by small diameter plastic <br /> pipes to the secondary treatment system, and from there on to a drip system. The small <br /> pipes are economical in cost of material and in ease of installation. The STEP systems <br /> are a much preferred option compared to traditional grinder pumps as the STEP tank will <br /> allow"foreign objects", such as wipes, to remain in the tank and not to go through the <br /> pump (highly increased clogging potential). <br />
