The Water Environment Federation (WEF) announced the launch of the Private Property Virtual Library (PPVL), a repository of information about wastewater utilities’ private property-related programs that address inflow and infiltration (I/I) in sanitary sewer systems, as well as building sewer maintenance issues.

As U.S. collection systems have aged, deteriorating pipe conditions and the growing problem of I/I – an excess of storm and ground water entering sanitary sewer systems – has placing an increased demand on wastewater utilities and can ultimately lead to sanitary sewer overflows (SSOs), even after the sewer mains have been repaired or replaced. Many utility managers must decide which is the most feasible and cost effective solution for their community: to treat excess sewer flows from I/I at a wastewater treatment facility; to contain SSOs by constructing large storage structures; or to remove I/I entering the public sanitary sewer system through privately-owned building service connections.

To date, more than 25 utilities have shared detailed information on their successful programs for the PPVL, which will be updated and expanded as more communities share their successes and additional private property related challenges are identified. Current library resources include an interactive discussion board, sample questionnaires, public education materials, letters to residents, ordinances and codes, operating and maintenance procedures, and design details and specifications.
