Stormwater Management Planning - A Collaborative Process

In recent years there has been an increasing awareness and focus on stormwater management and taking a ‘big picture’ point of view. Through integrated catchment management planning and use of appropriate modelling software, we are able to understand the system as a whole and build resilience into our designs.

This paper discusses the development and implementation of a stormwater strategy for Ashburton. The aim of the strategy was to understand issues with flooding, improve the resilience of the system, protect the receiving environments, accommodate future growth, support development, and is also expected to meet increased community expectations, a more stringent regulatory environment and climate change. This integrated approach to stormwater management is an example of how far stormwater management has evolved, and will optimise capital expenditure and provide better overall solutions for the Ashburton Community.
