Laterals and I&I
System owners know that building sewers and drains (laterals) are a major source of infiltration and inflow (I&I) that can affect the entire system. In fact, according to some reports, private sewer laterals can contribute up to 25% (or more) of total system infiltration. Unfortunately, not all municipalities have the knowledge – and in some cases, the rights – to properly inspect, clean, and repair private laterals to eliminate this major source of I&I.
NASSCO Standards
To build awareness among private property owners, realtors, and others involved in the assessment of private sewer laterals, NASSCO, Inc. has developed standards similar to its Lateral Assessment Certification Program (LACP™) to educate plumbers and small contractors on the proper inspection and cleaning of laterals. Through its Building Sewer and Drain Inspection (BSDI™) and Drain Cleaning Certification ™ Programs, consumers can now trust that Certified Drain Pros™ will do the work right.
Spread the Word
Please help us communicate the importance of properly inspecting and cleaning sewer laterals to avoid costly repairs and to minimize I&I in your city.

HOW IS BSDI DIFFERENT FROM LACP?
BSDI
Building Sewer & Drain Inspection
- Designed for Plumbers & Drain Cleaners Specifically built for professionals working on building sewers and drains, keeping their equipment, workflows, and best practices in mind.
- Easier Entry: Does not require PACP certification, making it a more affordable and faster path to NASSCO certification for professionals who don’t inspect mainline pipes.
- Inspection Direction: Inspections typically start inside or very near the building and move down the lateral toward the sewer main.
LACP
- Designed for System Owners & Asset Management Provides a more comprehensive assessment of lateral pipes, supporting long-term asset management and planning.
- Higher Certification Requirement : Requires successful completion of PACP Certification as a prerequisite, which may be unnecessary for professionals not working on mainline inspections.
- Inspection Direction: Inspections usually start from inside the sewer main and go up the lateral toward the building, without entering the building itself.
