Understanding who owns and is responsible for which sections of the sewer pipe network on your Central Coast property is more important than it sounds. The boundary between Council responsibility and your responsibility determines who pays for repairs, who authorises work, and what approvals are needed. Get this wrong and you can find yourself paying for repairs that should have been Council’s, or conversely, ignoring a problem that’s your legal obligation to fix.
The quick answer
On the Central Coast, property owners are responsible for all sewer and drainage pipes within the property boundary, up to the connection point with the Council sewer main in the street. Central Coast Council (formerly Gosford and Wyong Councils) is responsible for the main sewer in the road reserve. Work affecting the connection to or within the Council main requires a Section 68 approval under the Local Government Act.
The boundary: what’s yours, what’s Council’s
The key boundary is the property boundary, typically the street kerb line or the fence line. In most cases:
| Asset | Responsibility |
|---|---|
| Sewer pipes inside the property boundary | Property owner |
| Inspection shaft (boundary trap) at the property boundary | Sometimes Council, sometimes owner, varies |
| Sewer main in the road reserve | Central Coast Council |
| Stormwater pipes inside the property boundary | Property owner |
| Stormwater pits and pipes in the road reserve | Central Coast Council |
| Private drain connection to the Council main | Property owner (the connection fitting itself is often Council) |
The boundary inspection shaft (also called a junction trap or Council junction) is the device at the property boundary that connects your private drain to the Council main. Depending on when it was installed and the relevant instrument, it may be Council’s responsibility to maintain or the property owner’s. Check with Central Coast Council if there’s any doubt.
What Central Coast Council manages
Central Coast Council’s water and sewer utility (now integrated into Central Coast Council after the 2016 council merger) manages:
- The reticulated sewer network in roads and public land
- Sewer pump stations serving the network
- Wastewater treatment plants
- Water supply infrastructure
For properties on the Central Coast (the former Gosford and Wyong LGA areas), the sewer network is managed under the same entity. Contact Central Coast Council’s water and sewer team for issues in the road network.
When your private drain is the problem
The most common scenario property owners face: a blocked or failing sewer pipe that’s entirely on private property. This is your problem to fix.
How Council gets involved
Council rarely proactively inspects private drains. They typically become involved when:
- You’re connecting a new building or renovation, new sewer connections require a Section 68 approval
- Your pipe is exfiltrating sewage, a complaint or an environmental observation may trigger a Council investigation and a direction to repair
- Your drain is overloading the Council main, if groundwater infiltration through your cracked pipes is causing problems in the shared system, Council can require you to repair
- Development application, any DA requires assessment of drainage infrastructure
Council orders to repair
Under Section 124 of the Local Government Act, Council can issue orders requiring a property owner to:
- Repair defective drainage
- Connect to the sewer (for unconnected properties)
- Rectify illegal connections
These orders have compliance timeframes and can lead to Council doing the work and recovering the cost from the owner if not complied with.
Section 68 approvals for sewer work
Section 68 of the Local Government Act requires approval for work that connects to or affects the Council sewer system. This includes:
| Work type | Section 68 required? |
|---|---|
| Connecting new building to sewer | Yes |
| Installing or relocating an inspection shaft at the boundary | Yes |
| Relining or replacing a private pipe (no Council asset work) | Generally no |
| Digging into the Council main to make a new connection | Yes |
| Repairing a private drain without any Council main involvement | Generally no |
For standard drain relining within the property boundary, Section 68 approval is typically not required. The work is on your property, within your pipes. Your licensed plumber handles this.
If the relining job requires access to or work at the Council main (e.g., the connection fitting needs replacing), the plumber must obtain Section 68 approval from Central Coast Council before that work can proceed.
Licensing requirements for sewer work
All sewer drainage work in NSW must be performed by a licensed plumber and drainer. This is not optional. The NSW licence categories relevant to sewer work are:
| Licence type | NSW Fair Trading |
|---|---|
| Plumbing and drainage (tradesperson) | Required for all sewer and drain work |
| Plumbing and drainage (contractor) | Required to contract for plumbing work |
DIY sewer and drain work is illegal in NSW. A homeowner cannot legally perform their own sewer pipe repair, relining or connection work.
Ask to see your contractor’s NSW Fair Trading licence number. Verify it at the NSW Fair Trading online licence check.
Water and sewer access charges on the Central Coast
Central Coast Council charges property owners for connection to the water and sewer network through:
- Access charges (a fixed annual charge for connection to the network)
- Usage charges (for water consumption)
These charges apply regardless of whether you use the sewer service, simply for being connected. They fund the maintenance of the Council sewer network. This is distinct from the cost of maintaining your private drain, that’s entirely your responsibility, separate from Council charges.
What to do when you suspect a Council sewer main problem
If you believe the problem is in the Council main (not your private drain), contact Central Coast Council’s water and sewer fault reporting line. Signs that suggest the Council main may be the problem:
- Multiple properties in the street experiencing sewer problems simultaneously
- The blockage is downstream of your boundary inspection shaft
- Council has recently done works in the street
Be aware that Council may do a preliminary investigation and determine the problem is actually in your private drain, which is the most common outcome. Don’t assume Council responsibility without having your own private drain checked first.
Private drain mapping and as-built records
If you don’t know where your private sewer pipe runs, or what its condition is, there are a few options:
- CCTV inspection: A camera fed through the pipe maps its route, depth and condition in real time
- As-built drawings from Council: Central Coast Council may have records of sewer connections from when the property was first connected
- Previous plumbing permits: If drainage work was permitted in the past, the permit may include a drainage diagram
Having a current drainage diagram for your property is good practice for any property owner, it helps contractors locate inspection shafts, plan work, and avoid other services.
Frequently asked questions
How do I find out where the Council sewer main is in my street? Contact Central Coast Council and request a sewer service diagram for your property address. The council has GIS data showing the sewer network. Alternatively, your plumber can use an electronic pipe locator to trace the run from your inspection shaft.
If a tree in the Council nature strip has damaged my private sewer pipe with roots, is Council responsible? Generally no. The private sewer pipe is your responsibility. The fact that the roots came from a Council-maintained tree doesn’t transfer responsibility for your pipe to Council. You may have a claim in some circumstances (legal advice warranted), but the standard outcome is that you repair your own pipe.
Does Central Coast Council have a rebate for drain relining? Not as a standard program. Some councils have offered rebates for private inflow and infiltration reduction (where homeowner pipe repairs reduce groundwater entering the sewer network). Check with Central Coast Council’s water and sewer department for any current programs.
What if I discover a Council sewer pipe running through my property (not just to the boundary)? Some older properties have Council sewer pipes running through private land under formal easements. These easement pipes are Council’s responsibility to maintain. If you discover one, notify Council and confirm the easement exists in your property title records before doing any work near it.
Do I need a plumber to deal with Council, or can I contact them directly? For fault reports and enquiries, you can contact Council directly. For work requiring Section 68 approval, the application is typically made by the licensed plumber who will do the work, in consultation with you as the property owner.
