The City of Naperville Puts the Plug in Inflow and Infiltration

摘要

Inflow and infiltration, or better known as I&I, has increasingly become the topic of conversation, articles, blogs and videos of late. Heavy rainfalls in the Midwest and Northeast United States — some being classified as high as 500-year and 1,000-year events — have strained the sanitary sewer collection and treatment facilities of many cities.Basements flooded with sewer water, sewage treatment plants dumping partially or untreated wastewater into streams, rivers and lakes, EPA mandates and fines, rainwater and sewage spewing from manhole covers, beaches closed because of water contamination and other stories of this nature fill magazines, web content and television news stories.
