Private Property Inflow And Infiltration Inspection Procedures
For Contractors
The following instructions and standards are intended for property owners and their contractors when
choosing to use a private contractor to complete the Point of Sale Sanitary Sewer Service Inflow and
Infiltration (1/1) Inspection. Private inspection contractors will need to complete the inspection using
the City of Orono's Inflow/Infiltration Inspection Form, available on the City website. Inspectors will
require access to the basement or lowest level in the home or building and access to all sewer
cleanouts, sump pump(s), and sump pump plumbing. The televised portion of the UI inspection is to
note defects in the sanitary sewer lateral, which result in infiltration and ex -filtration. The purpose of
the private property inflow and infiltration (1/I) inspection is to reduce the flow of clear water into the
sanitary sewer system via cross connections (inflow) from sump pumps, foundation drains, roof
leaders, cisterns, and other clean water sources connected to the sanitary sewer system. In addition,
the program aims to reduce indirect flow of clean water into the sanitary sewer system (infiltration)
through pipe and pipe joint defects.
