Manhole Surveys

Common Reasons to Have a Manhole Survey

• Accurate Asset Mapping – To identify the exact locations, depths, and dimensions of manholes for infrastructure planning and records.
• Condition Assessment – To check for structural defects, cracks, blockages, or other issues inside the manhole.
• Drainage Network Planning – Essential for mapping underground drainage and sewer systems for new developments or upgrades.
• Flood Risk Prevention – To ensure manholes are functioning correctly and not contributing to localised flooding.
• Compliance with Regulations – Required by local authorities or water companies to ensure sewer systems meet safety and environmental standards.
• Capacity Checks – To confirm whether a sewer or drainage system can handle current and future loads.
• Preventative Maintenance – Helps identify issues early before they develop into costly repairs or blockages.
• Construction Planning – Needed before construction, roadworks, or utility installation to avoid damaging underground assets.
• Ownership and Responsibility Verification – Helps determine which assets are private versus public for maintenance responsibilities.
• Accurate GIS or CAD Data – Surveys provide precise data for updating digital mapping systems.
• Safety Evaluations – Detects hazards like corrosion, toxic gases, or structural weaknesses that could be dangerous for workers.
• Manhole Cover Surveys – Ensures covers are correctly positioned, accessible, and not damaged, reducing trip hazards and accidents.
• Support for CCTV Drain Surveys – Manhole surveys are often done alongside CCTV inspections to give a complete picture of a drainage system.
• Environmental Protection – Ensures there are no leaks or contamination risks from damaged manholes affecting the environment.
