Clutha's stormwater system is a network of drains, gutters, pipes, mud tanks, detention ponds, stormwater reserves and other associated infrastructure.
Stormwater is rain or snow runoff that does not soak into the soil. When an area is developed, stormwater generally increases due to runoff from impermeable surfaces (e.g. roofs, roads, carparks, or compacted soil).
Unmanaged stormwater can create two major issues: one relates to the volume and timing of runoff (flooding) and the other relates to potential contaminants the water carries with the potential to pollute our waterways.
