Immediate drain help

What to do first in Mosman

Tell us what is backing up before choosing a service. It helps to know whether water is still rising, if rain changes the problem and where the drain can be reached.

  1. 01

    Active overflow

    Stop using the drains or fixtures that make the water rise, keep people and pets clear and call for blocked drain help in Mosman.

  2. 02

    Recurring or slow drains

    Tell us which drains are slow and whether the same problem has been cleared before. CCTV may help if it keeps returning.

  3. 03

    Shared or rain-related symptoms

    Tell us if several homes or units have the problem, or if pooling appears only during rain.

Not sure who is responsible?

Who arranges the work depends on where the blockage is. Private drains are generally managed by the property owner, shared pipework may involve strata, Sydney Water manages its wastewater network and public stormwater questions for this address may involve Mosman Municipal Council.

Getting a drain checked in Mosman

Tell us what is backing up, when it started and where the drain can be reached safely.

Mosman Council says owners maintain their property stormwater systems. A private wastewater branch, common-property pipe, council stormwater asset and Sydney Water wastewater main follow different boundaries, so the pipe causing the problem and the problem location should be established before responsibility or repair is decided.

  • Unit and shared drain assessment with strata or building management

    List which fixtures and levels are backing up so one unit’s branch can be separated from a shared stack or main line.

  • Clearing blocked house drains through a confirmed outdoor access point

    Tell us when the pooling starts, which pit or grate fills and whether toilets or indoor drains are behaving normally.

  • CCTV when a blockage keeps returning or the pipe involved is unclear

    Once the drain is flowing, CCTV can show why the same pipe keeps blocking and where the problem sits.

Is a blocked pipe in a Mosman unit automatically common property?

No. Responsibility depends on the pipe and lots served. Check whether one fixture, one lot or several lots are affected and confirm the problem location before invasive work is authorised.

Who maintains private stormwater pipes in Mosman?

Mosman Council says property owners are responsible for maintaining their stormwater systems in good working order. Council is responsible for its public assets, while wastewater responsibility is assessed separately.

What should I do if wastewater is overflowing?

Stop using fixtures that make the water rise, keep people and pets clear and call. Tell us where the overflow is and whether it is still rising.
