Inflow does not include,and is distinguished from,infiltration. Infiltration is water other <br /> than wastewater that enters a sewer system(including sewer service connections and foundation drains)from the <br /> ground through such means as defective pipes, pipe joints,connections,or manholes.Infiltration does not include, <br /> and is distinguished from,inflow. <br /> The new crushing facility could impact the collection system by disturbing the manholes,pipes,and service lines <br /> resulting in an increase in the infiltration of groundwater into the collection system.This increase in infiltration is in <br /> direct conflict with the CDPHE compliance schedule to reduce inflow and infiltration into the collection system. <br /> Damage to the collection system could also result in exfiltration or seepage of wastewater into the ground which <br /> would be a direct violation of the Clean Water Act.The cost of repair of this infrastructure would fall to the Sanitation <br /> District and the residents of Leadville. The District's WWTF consists of a headworks for screening and grit removal, <br /> two aeration basins,two covered clarifiers,a polishing pond,and a chlorine contact chamber for disinfection. Nearby <br /> seismic activity from the proposed Mill could also have detrimental effects to the existing WWTF structures that are <br /> required for wastewater treatment and permit compliance. <br />
