Sewer Lateral Condition Assessment (LACP)

Kiwa T2 provides sewer lateral condition assessments in accordance with the National Association of Sewer Service Companies (NASSCO) Lateral Assessment Certification Program (LACP). LACP provides a standardized approach for coding, documenting, and evaluating the condition of sewer service laterals using CCTV inspection technologies. 

Inspections can be completed either with or against the direction of flow. Where direct access is unavailable, specialized lateral launch equipment can be deployed from the mainline sewer and navigated through blind lateral connections to inspect the service lateral. This approach allows condition data to be collected without requiring direct access from the surface.

During the inspection, CCTV equipment records video of the lateral while trained personnel document observations using standardized LACP coding. Inspection results help identify structural defects, operational issues, root intrusion, infiltration, obstructions, and other conditions that may impact system performance.

The Sewer Lateral Condition Assessment service by Kiwa T2 is intended for municipalities, water and wastewater utilities, consulting engineers, asset management professionals, infrastructure owners, developers, contractors, and organizations responsible for maintaining or rehabilitating sewer networks. This service is particularly valuable where the condition of service laterals must be evaluated for capital planning, rehabilitation programs, due diligence investigations, inflow and infiltration studies, pre-construction assessments, post-construction verification, and system performance reviews. These organizations are typically responsible for inspecting, maintaining, managing, designing, or upgrading underground wastewater infrastructure.

Kiwa T2 combines advanced CCTV inspection technologies with practical sewer infrastructure expertise to deliver reliable condition assessment information. Our capabilities include lateral launch technology that allows inspections to be completed both with and against the direction of flow, including situations where direct access is not available. 

Kiwa T2 follows recognized NASSCO condition assessment methodologies, including PACP, MACP, and LACP standards, ensuring consistent and industry-recognized reporting. Our team includes experienced engineers, technicians, and CCTV specialists who understand how condition assessment data supports asset management, rehabilitation planning, utility engineering, and mapping initiatives
