Stormwater Drains

Council’s stormwater system comprises of approximately 400km of underground pipes, 22km of open unlined drains, 15km of open lined drains, 9,500 pits and 300 culverts.

Council endeavours provide and maintain a stormwater system that meets the needs of the Darwin community through continual improvements to manage flooding and safety issues whilst minimising pollutants entering the system.

Drainage infrastructure is inspected and maintenance scheduled in accordance with Council's Capital Works and Infrastructure Maintenance programmes. Upgrades of the system are undertaken as development increases and the need arises.  There are several contribution plans in place that ensure the system will be upgraded when required.

As part of protecting the environment and Darwin’s Harbour, dozens of gross pollutant traps are in place to collect rubbish and prevent it from entering the ecosystem.  New sites for these are continually assessed and new traps are installed each year.

New developments and subdivisions (other than single dwellings) must supply a stormwater plan to the Council for approval to ensure that the stormwater is drained effectively and meets Council’s guidelines.  If you would like to connect to Council’s stormwater system a permit is required to ensure the works are carried out the correct specifications.
