Stormwater Network Intelligence for Local Government

A practical guide to building a clearer, field-verified view of your stormwater network, asset condition, capacity, risk and future works priorities.

Council stormwater teams are under growing pressure from ageing infrastructure, incomplete asset records, urban development, flooding complaints and increasingly intense rainfall.

Yet much of the network remains underground and poorly understood. Decisions about maintenance, renewal and capital works can still depend on outdated GIS records, incomplete connectivity data or limited knowledge of actual pit and pipe condition.

This guide explains how Stormwater Network Intelligence brings field verification, high-accuracy survey, condition assessment, GIS intelligence, hydraulic modelling and strategic planning together to create a more reliable evidence base for council decision-making.

Inside, you’ll learn how councils can investigate more of their network within available budgets, identify where detailed CCTV or cleaning is really needed and turn better stormwater data into practical maintenance, renewal and capital works priorities.

What’s Included

Bringing Hidden Stormwater Risks to the Surface
Understand how ageing assets, incomplete records, development and changing rainfall conditions can create risks that are difficult to see until problems emerge.
When Stormwater Network Intelligence Makes Sense
See the common triggers for investigation, from recurring flooding and drainage complaints to unreliable asset data, planning requirements and uncertain network capacity.
Review and Scope
Learn how existing GIS records, complaints, known hotspots and data gaps can be reviewed to focus field investigation where it will create the greatest value.
Verify What Is Actually in the Ground
Discover how field inspections and high-accuracy survey can confirm pit and pipe locations, connectivity, dimensions, materials, levels and missing assets.
Assess Condition and Risk
See how condition ratings and cost-effective fixed-zoom pipe inspections can identify defects, blockages, root intrusion and assets requiring further investigation.
Connect the Data
Learn how verified field information can be quality checked, linked and structured into practical GIS-ready datasets for asset management and modelling systems.
Model Network Performance
Understand how field-verified data and hydraulic modelling can help identify capacity constraints, flooding hotspots, choke points and potential mitigation options.
Turn Evidence Into a Works Plan
See how condition, capacity and risk information can support preventative maintenance, critical asset rankings, renewal programs and longer-term capital works priorities.
See the Approach in Practice
Explore how Southern Grampians Shire Council is combining inspections, survey, condition assessment, hydraulic modelling and planning to better understand the Hamilton stormwater network.
A Smarter First Step Than Inspecting Everything
Learn how broad first-pass inspections can help councils investigate more of the network before directing detailed CCTV, cleaning and specialist investigation to the assets that need it most.

Better Stormwater Decisions Start With Better Evidence

If your council is dealing with incomplete drainage records, nuisance flooding, ageing assets, uncertain pipe condition or capacity, compliance requirements or difficult budget decisions, this guide provides a practical pathway from network uncertainty to clearer priorities.

RapidMap can help councils tailor a Stormwater Network Intelligence program around existing data, known risk areas, available budgets, estimated valuations, developer handover verifications and future planning requirements, creating a stronger foundation for maintenance, renewal and long-term investment.
