GIS automation and hydraulic inventory for PIGSS projects
We extract hydraulic measurements from 3D manhole models and detect GIS discrepancies to accelerate inventory, modelling, and technical audit workflows.
The Problem
Hydraulic inventories are often slow, manual, and difficult to validate
Water utilities, sanitation operators, GIS teams, and hydraulic engineering firms need reliable manhole and pipe data for modelling, audits, and PIGSS-related projects.
Incomplete GIS inventories
GIS layers may be outdated, incomplete, or inconsistent with the real field geometry.
Manual manhole measurement
Extracting invert levels, pipe diameters, directions, and connections manually is slow and repetitive.
Technical justification
Teams need traceable evidence for levels, diameters, pipe connections, and discrepancies.
The Solution
From 3D manhole models to GIS-ready hydraulic data
We process 3D models or point clouds of drainage manholes, detect the main geometry, unfold the internal wall into 2D, identify pipe openings, and cross-check results against GIS layers.
Deliverables
Technical outputs ready for engineering and GIS workflows
Manhole and pipe CSV
Structured hydraulic parameters for manholes, pipes, openings, levels, and confidence scores.
GeoPackage for GIS
GIS-compatible layers for review, modelling, and integration into existing workflows.
Review images
Visual evidence showing detected geometry, pipe openings, and measurement references.
GIS discrepancy map
Layer showing mismatches between GIS inventory and detected 3D geometry.
PoC report
Technical summary with results, limitations, accuracy observations, and next-step recommendations.
Deployment roadmap
Recommended path from PoC to production workflow for engineering or utility teams.
Recommended PoC
20–50 real manholes + technical validation
The recommended first step is a focused PoC using real 3D manhole data and existing GIS layers. The goal is to validate detection quality, discrepancy value, and workflow fit before scaling.
