Inflow & Infiltration (I&I)
January 28th, 2020

Mississauga Grand, 35 Brunel Rd,  Mississauga, ON, L4Z 3E8


Inflow and Infiltration (I&I) refers to rain and groundwater that enters the sanitary sewer as extraneous flows. A certain amount of I&I is unavoidable but when I&I exceeds design allowances, sewer capacity is cnsumed and may result in overflows, risks to health, damage to the environment and increased conveyance costs.   These issues are becoming more important to Municipalities who are struggling to manage thier limited infrastructure budgets. This workshop provides attendees with information regarding common I&I contributors, how to locate them and how to reduce thier impact using trenchless methods of assessment. 

Who should attend?

Engineering consultants, contractors, technologists, municipal employees, field technicians, suppliers, infrastructure asset managers and anyone else who has an interest in municipal pipelines and wants to keep abreast of emerging industry trends to save money and environment.
