There are a number of authorities with different roles relating to drainage and management of the District.

Melbourne Water's Koo Wee Rup team are responsible for the construction and maintenance of over 500 kilometres of carrier and precept drains within the District.

• Constructed precept drains are watercourses built to drain the district, and originate from within the district. Melbourne Water maintenance includes grass cutting, desilting, weed control, and structural works that ensure the drains continue to perform as designed.
• Carrier drains are larger waterways starting upstream of the district, which take water from precept drains and carry it through the area – Bunyip River, for example. Works on these waterways are also co-funded (50%) by a separate charge known as the Waterways and Drainage Charge.
