Private Property Infiltration and Inflow Control

Infiltration and inflow (I/I) control efforts are a significant challenge for utilities and private property I/I sources present even greater hurdles.Private Property Infiltration and Inflow Control offers guidance on methods to identify, locate, and estimate the magnitude of private property I/I, as well as best practices for employing corrective actions to control it.

Intended as a resource for utility and collection systems managers, engineers and scientists, and public health officials, the guide also outlines the critical elements for implementing a successful private property program and navigating the many barriers to implementation, including how to:

• Understand the legal, funding, political, and regulatory considerations that need to be addressed as part of a private property program;
• Distinguish the various types of private property programs that utilities are using, including enforcement-based programs, point-of-sale inspection programs, and assumption of public responsibility for maintenance of varying portions of the private sewer.

Included are case studies of leading private property programs from around the country, as well as results of the 2015 WEF Private Property I/I Survey.
