I&I is a quarterly supplement to Municipal Sewer & Water™ focusing exclusively on one of the most prominent issues municipal wastewater utilities are facing:…
Inflow is stormwater that enters the sewer system through rain leaders, basement sump pumps or foundation drains illegally connected to the sewer. Together, inflow and infiltration place a burden on collection systems and wastewater treatment facilities. Learn more by requesting the training guide: Sew...
A major challenge sanitary districts everywhere face is recurring and growing inflow and infiltration (I&I), from substantial amounts of groundwater and stormwater entering the sewer during periods of heavy rain. This issue is of paramount importance, as heavy rainfall can cause the intrusion of ...
Fractionation of Infiltration and Inflow (I/I) components in urban sewer systems with regression analysis (2007). Fraction of infiltration and inflow (I/I) components in urban sewer systems with regression analysis. 6th Int Conference NOVATECH, Lyon, 1227-... C Karpf,T Franz,P Krebs 被引量:...
Smoke testing is one of the oldest methods used to discover inflow and infiltration (I&I) issues into our sewer collection systems. Inflow occurs when surface water is able to enter a system through public or private sources. Infiltration occurs when groundwater enters through structural defects ...
