Cross-bore Prevention and Verification

What is Cross Bore Prevention and Verification and what it includes
Cross-bores occur when a utility installed via HDD unintentionally intersects an existing underground pipe, such as a sanitary sewer or storm sewer. These conflicts can create significant safety, operational, and asset management risks if they are not identified before or during construction.
Kiwa T2 provides CCTV-based cross-bore prevention and verification services to support safe utility installation practices and help project teams better understand existing underground infrastructure. Using sewer inspection technology, our team inspects sanitary and storm sewer systems to identify pipe alignments, service lateral locations, and potential utility conflicts that may affect planned HDD installations OR have been affected by HDD installations.
Prior to construction, CCTV investigations can be used to support route planning by providing additional information about underground infrastructure that may not be accurately represented in existing records. Following installation, verification inspections can be completed to confirm that newly installed infrastructure has not interfered with existing sanitary or storm systems.
Who is it for?
The Cross-Bore Prevention and Verification service by Kiwa T2 is intended for utility owners, utility contractors, telecommunications providers, gas utilities, electrical utilities, municipalities, and project managers responsible for horizontal directional drilling (HDD) projects. These organizations typically plan, design, construct, operate, or maintain underground infrastructure and require accurate information to manage utility conflicts, reduce construction risk, and protect existing sanitary and storm sewer systems.
Benefits of Cross Bore Prevention and Verification
- Helps identify potential utility conflicts before HDD construction begins
- Reduces the risk of accidental damage to sanitary and storm infrastructure
- Supports safer trenchless construction practices
- Provides documented verification following utility installation
- Improves confidence in underground asset information
- Assists with risk management and project due diligence
- Creates a visual record of underground infrastructure conditions and locations
