CASE STUDY
Among its most critical assets is a largely unseen network of stormwater pits and pipes that helps protect roads, properties and communities from flooding. But incomplete records, uncertain asset locations, and limited visibility into network conditions made it difficult to understand exactly how the system was performing.
Council needed to move beyond responding to individual drainage problems and develop a more complete, evidence-based understanding of the Hamilton stormwater network.
This case study explores how RapidMap, working alongside Environmental and Civil Engineering partners, combined targeted field validation, spatial asset intelligence and hydraulic modelling to give Southern Grampians a stronger foundation for maintenance, renewal, risk management and long-term stormwater planning.



For councils responsible for ageing, with often poorly documented drainage networks, responding to individual flooding issues is only part of the challenge.
Effective stormwater planning requires a clear understanding of what assets exist, where they are located, how they are connected, what condition they are in and how the network behaves during rainfall events.
RapidMap helps councils connect field reality with spatial asset data and engineering analysis. Through targeted stormwater inspections, accurate survey data, GIS-ready asset information and collaborative project delivery, RapidMap provides the practical intelligence needed to support maintenance, renewal, risk management and long-term investment decisions.
For Southern Grampians Shire Council, that means moving towards a more proactive and evidence-based approach – one that provides a clearer view of drainage risk today while creating a stronger foundation for the decisions of tomorrow.
If your council is looking to improve stormwater visibility, understand flood risk and build a more practical foundation for future planning, RapidMap can help.
