Deep Sewer Condition Assessment

What are deep sewer condition assessments?

Deep sewer condition assessments are comprehensive evaluations of the structural and operational integrity of large, often inaccessible underground wastewater or stormwater conveyance systems. At Academy Geomatics, our deep-sewer inspection system is designed to deliver detailed, data-rich surveys combining:

• 3D LiDAR mapping: Accurate measurement of internal pipe geometry to identify deformations, collapses and structural defects
• High-resolution visual inspection: 4K video and still imagery offering clear views of pipe walls, joints, intrusions and other condition issues
• Sonar profiling: Precise underwater mapping to detect silt levels, blockages and submerged deformities in real time
• Echo sounding and acoustic silt detection: Measurement of silt depth and distribution throughout the sewer network
• Self-contained float deployment: Independent operation towed through pipelines, eliminating the need for confined-space entry or tethered data transmission

Why choose Academy Geomatics?

From large-scale municipal networks to high-risk, ageing infrastructure, our deep sewer condition and positional surveys deliver the clarity, safety and strategic insight you need. Benefit from:

• Purpose-built sensor-integrated systems: Sewer profiling solutions designed for complex networks
• Deep expertise: Geospatial and underground utility surveying specialists
• End-to-end service: From planning through to data analysis
• Best practice alignment: Compliance with industry guidance and health and safety regulations
• Trusted partner: Major UK water utilities rely on us for mission-critical inspections

We have worked closely with Northumbrian Water, and our system mapped significant silt accumulations and generated actionable 3D models for maintenance planning – ultimately improving operational safety by removing the need for man entry. This data-driven approach also optimised cleaning schedules, leading to measurable cost savings and enhanced infrastructure resilience. Contact us today for support with your project.
