Description
Description | Thames Water is seeking to develop the mapped sewer network throughout Greater London and the Thames Valley area, in order to reduce blockages, internal and external floods and pollution. Unmapped sewers lead to a delay in Thames Water locating and attending blockages, floods and pollution, affecting local communities and the environment. The objective of FA2241 is to map any unmapped sewer networks at scale, speed and accuracy, directly supporting the Pollution Incident Reduction Plan (PIRP) that Thames Water is working towards during AMP8. Lot 1 - Aerial Mapping: Capture of 2,484 km² across 71 Sewer Drainage Area Catchments (SDACs) using manned aircraft, delivering georeferenced 2D, oblique 2D, and 3D imagery. Lot 2 - Asset Detection: Detection of manholes, gullies, rainwater downpipes, soil stacks, misconnections, and outfalls with confidence grading. Lot 3 - Sewer Inferencing: Semi-/automated inferencing of unmapped sewers, laterals, drains, rising mains, and selected SPSs, achieving ?80% accuracy. |
