r <br /> s Ile <br /> } <br /> �rt` �:, ,r tl <br /> collection systems,effluent sewer collection systems,and conventional t y,. � <br /> gravity sewers.Installing gravity sewers was not feasible because the <br /> town was spread out over a wide area and had paved streets with <br /> underground utilities,so the expense of installing large-diameter sewer <br /> lines would be great. <br /> After thorough evaluation,Truesdate elected to install an effluent <br /> sewer system with small diameter mainlines,below frost depth,that <br /> conveys primary treated effluent from individual interceptor tanks to the <br /> secondary treatment facility.Using small-diameter effluent sewers saved <br /> the community thousands of dollars in upfront and life-cycle costs. <br /> With upfront capital costs minimized,funding was secured through <br /> Iowa Department of Economic Development Community Development <br /> Block Grants and USDA Rural Development loans and grants.All funds <br /> were administered through ILRW,which will own and operate the <br /> system, <br /> After several months of operation,effluent from the AdvanTex system <br /> averaged 9.8 mglL BOD5,4.8 mg1L TSS,and 3A mglL NH3-N,even <br /> though average low winter temperatures in Truesdale regularly <br /> approach 0°F.Together,the robust AdvanTex technology and the <br /> affordable effluent sewer system were an appropriate solution to the Distributed and Supported 8y <br /> economic and engineering problems faced by this small community, <br /> For an introductory video about Orenco Effluent Sewers,go to wv w.
