Utility Network GIS & Asset Lifecycle Automation
Engineering-grade reference for pipe and cable topology, outage routing, spatial QA/QC, maintenance scheduling, compliance reporting, and CI/CD-driven asset lifecycle automation.
This site exists to help utility professionals automate and scale critical infrastructure workflows. Whether you are migrating from legacy geometric networks to a topology-aware Utility Network, hardening outage response with real-time telemetry, or wiring spatial validation into your CI/CD pipelines, the patterns here are written for production deployments — not toy demos.
Each section combines the architectural reasoning behind a workflow with concrete Python automation, validation checkpoints, and integration patterns. Code blocks are runnable, references point at primary sources, and every recommendation aligns with the operational realities of utility engineers, GIS technicians, and infrastructure teams.
Pick a starting point below and follow the cross-links to drill into specific tasks — connectivity rule design, subnetwork controllers, upstream/downstream tracing, valve isolation, branch versioning and conflict resolution, batch topology processing, storm-mode dispatch, field data capture, condition-based maintenance, and compliance reporting.
What you'll find here
The content is organised into focused sections. Each section index is a strategic overview; deeper pages drill into specific automation patterns, validation routines, and integration recipes you can adapt to production.

New to topology-aware utility networks? These pages are the most direct way in.
- Understanding UN vs. traditional GIS networks Why a topology-aware Utility Network behaves differently from a geometric network — and what that changes for your data model.
- Asset hierarchy design for water & electric Structure assemblies, devices, and junctions so tracing, validation, and lifecycle automation stay reliable at scale.
- Configuring connectivity rules for pipe & cable The rule sets that make upstream/downstream tracing correct, and how to validate them in CI.
- Upstream & downstream tracing algorithms The tracing logic behind isolation, impact analysis, and outage routing — with Python automation patterns.
- Subnetwork management & controller configuration Where circuit and pressure-zone membership actually comes from, and why a stamped subnetwork name goes stale without anyone noticing.
- Asset lifecycle & maintenance automation Condition-based scheduling, lifecycle state machines, field capture, CMMS sync, and automated compliance reporting for utility assets.
Newly added
Four areas added in this build, each with its own implementation guides.
Subnetwork Management & Controller Configuration
Controllers, tier types and propagated attributes — and the stale membership that quietly misroutes every analysis built on it.
Read the topic →Branch Versioning & Conflict Resolution
Version lifecycle, the conflict classes a network model produces, what may be resolved by rule, and when a batch job should read a snapshot instead.
Read the topic →Storm Response & Restoration Analytics
Storm operation as a declared regime: relative thresholds, a fixed dispatch cadence, re-derived impact sets, and the records a filing is assembled from.
Read the topic →Field Data Capture & Mobile Sync
Three layers of validation, accuracy budgets per asset class, offline conflict handling, and the feedback path that decides whether field data improves.
