Blocked drains in Hills District
If wastewater is rising, stop using affected fixtures and call. For a slow or recurring drain, record which fixtures are involved and whether rain changes the symptom so the private sewer and stormwater paths can be checked separately.
Blocked drain help across Hills District
Blocked drain diagnosis and clearing across the Hills District, with the property address used to identify the relevant council and separate private drains from public assets.
- Hills District addresses can fall within The Hills Shire, Hawkesbury, Blacktown, Hornsby or Parramatta council areas.
- Rain-related pooling is traced through pits, grates, downpipes and the connected stormwater line rather than treated automatically as a sewer blockage.
- Recorded outdoor drain-clearing work supports the regional access and clearing guidance.
- Urgent wastewater overflow and blocked toilet triage
- CCTV inspection for recurring or unclear restrictions
- Stormwater pit and inlet checks where rain changes the symptom
- Clear, inspect and repair decisions based on the fault found
Private drains, council stormwater and Sydney Water
Private drains remain distinct from Sydney Water wastewater assets and council-managed stormwater. The relevant council changes with the property address, so the asset and fault position must be identified before responsibility is assigned.

Hills District blocked drain FAQs
Which council handles stormwater in the Hills District?
The council depends on the property address. Hills District properties can sit within The Hills Shire, Hawkesbury, Blacktown, Hornsby or Parramatta council areas, while private drains remain the property owner’s responsibility.
Who handles a blocked sewer in the Hills District?
A licensed plumber can investigate a blockage in private wastewater pipes. Sydney Water handles faults in its network. The fault location and connection point determine responsibility.
Does rain mean the sewer is blocked?
Not necessarily. Rain-related pooling may involve stormwater pits, inlets or connected lines, while wastewater backups follow a different path. Report which drains are affected and whether the symptom happens only during rain.
