Drainage Frequently Asked Questions
Stormwater flows are generated from rain. The rainwater falls on a variety of surfaces which influence the quality and quantity of water absorbed into the ground, those in the stormwater system and those flows across hard surfaces also called run-off. The City’s stormwater drainage system carries these flows outfall generally to creeks, which then flow to rivers and ultimately the ocean. It is important only clean water goes into this system.
Stormwater is completely separate to the sewerage system. Toilets, sinks, showers and baths in your home are connected to the sewerage system which flows to treatment plants to treat it for reuse or release. Coliban Water is responsible for this system.
The drinking water supply to taps in your house is also a different system. It is supplied under pressure from treatment plants and reservoirs. Coliban Water is responsible for this system.
House gutters, downpipes, buried pipes from your property to the street or to the pit at the rear of your allotment and any other private drainage structures such as grated trenches and pits within private property, are the responsibility of the property owner.
The Property owner is responsible for the installation, maintenance, operation and replacement of all private stormwater to the City specified Legal Point of Discharge or connection point (See below section on ‘Permits and Approval of Works’).
The City is responsible for all assets downstream of this connection point, including drainage pits, pipes, side entry pits in the street, manholes, headwalls, culverts under roads, open channels and retardation basins.
How to report problem of a City drainage asset:
When constructing hard surfaced areas (e.g. driveways, concrete and paved areas), landscaping and any other impervious surfaces or drains you must control the stormwater in order to prevent concentrated flows onto any adjacent property. A landowner must not discharge concentrated flows illegally across lot boundaries. A concentration of flow is anything that is beyond the natural run off of the land in its undeveloped state.
Every property owner is responsible for ensuring that water is discharged from their property correctly and does not affect adjoining owners. Inadequate or damaged drainage can cause issues such as damage to buildings, undermining foundations or landslip, which may result in costly repairs or legal action from affected persons.
Council have no legislative power to require a person to maintain or install stormwater systems to existing buildings or install drainage to landscaping. Liability arising out of the flow of water is an offence under the Water Act 1989 - Section 16, if your neighbour's water drainage is causing issues to your property, you should first talk with your neighbor and try to reach a mutually suitable solution. If this does not work, you can contact the Dispute Settlement Centre for a non-legal mediation service, or take legal action through a solicitor.
If you are concerned about the stormwater drainage system in any area or find a pit or drain that needs inspection or maintenance you can lodge a request for our staff to investigate and program the required treatment of the issue.

We're updating the information on flood-prone properties and areas. We encourage you to register your property if it has experienced significant flooding. This helps us progress stormwater investigations and drainage projects.
Regular customer requests received include: Blocked pits and pipes; broken pits and pipes; undersized pipes; pipe intrusions (tree roots, utility services and resident tampering); poor earthworks practice (e.g. directing surface flows to house) and; property in low-lying area.
If you observe stormwater is entering from a neighbouring property, in the first instance speak to your neighbour. They may not be aware of the issues their property may be causing. If agreement cannot be reached, consider contacting the Dispute Settlement Centre of Victoria:
All properties owners have legal obligations to capture, collect and dispose of stormwater from all hard surfaces, through underground pipes to the City nominated Legal Point of Discharge so as not cause a nuisance to adjoining property owners. See Water Act.
In general, your neighbour is responsible for controlling stormwater runoff from their property. Water flowing from hard surfaces, such as paving or roofing, should be collected and discharged in an approved manner. Your neighbour is not responsible for controlling stormwater runoff from natural surfaces, such as grassed or treed areas. Any excess stormwater water caused due to significant landscaping works must also be controlled.
Problems with overland stormwater flow between neighbouring properties are a civil matter to be resolved between the respective owners. City has no legislative powers to intervene. More information on how to address this issue at: https://www.vcat.vic.gov.au/case-types/unreasonable-flow-of-water-between-properties
If you believe the City’s stormwater drainage system has caused the problem, please report to the City for an investigation after the event.
Water being blocked/diverted upstream away from my dam” – This is a private matter between property owners. The City recommends speaking with your neighbour in the first instance to attempt to reach a resolution. If a resolution cannot be reached consider contacting the Dispute Settlement Centre of Victoria:

If your property is listed as flood prone then it is expected that during heavy rainfall you can be affected by flood waters.
Planning and floodplain management authorities are responsible for identifying properties that may be subject to flooding from a 1% AEP flood event. Properties that have been identified as being flood prone may be included in a ‘flooding’ overlay in the planning scheme.
An overlay is a map in a planning scheme that shows the location and extent of special features, such as where land may be subject to flooding. In the case of flooding, overlays are an important way to manage development in order to minimise the effects of overland flows and flooding on new buildings and ensure new development does not adversely affect other existing properties. If your property is affected by flooding, new development must be designed so that new buildings are protected from a 1% AEP flood event. In addition, development must not increase flood risk or hazards to people and neighbouring properties.
The legal point of discharge is a point either within the allotment or at the allotment boundary specified by City where stormwater from a property must be discharged. This point must then be properly connected to City infrastructure (typically a stormwater drain or a drain in an easement where available, or street kerb and channel).
City is regularly asked to provide direction on the legal point of discharge for both existing properties and the redevelopment of residential, commercial and industrial developments.
Under Section 133 (2) of Building Regulations 2018, it is a legal requirement that all property owners ensure that the stormwater drainage from their property is directed to a legal point of discharge and properly connected to City infrastructure, as nominated by the City.
This is a legal requirement every time you change your roof or paving, irrespective of whether you have obtained this type of approval for your property in the past.
The property owner is also responsible for the maintenance and repair of the drain between their legal point of discharge and the ‘connection point’ into City infrastructure, even if this connection point occurs within a street reserve or public land.
In the building process and in relation to building permit applications, a legal point of discharge must be obtained. A legal point of discharge may also be required if your current drainage system is not connected anywhere, is inadequate, or you have a proposed modification.
You can apply for a legal point of discharge from City, which provides the location to which the stormwater drainage discharge from your land must be directed. There is an application fee for this report.

The City’s stormwater drainage network is viewable in the City’s public mapping system. Unfortunately, the City has very limited information regarding private property stormwater drainage.
The City provides a public mapping service where a lot of information is available including, location* of the City’s drainage network and; creek & overland flowpath information. The mapping system is available here: http://bendigo.pozi.com/
*location is indicative only and no excavation is to take place without physically locating the asset prior to any works. Further indicative underground service information is available at ‘Dial-before-you-dig’. Contact can be made via:
- Phone 1100
- Log request on https://www.1100.com.au/#
Be aware aerial photos don’t always align with the property boundaries in the mapping system, so be sure to engage a licenced surveyor to peg out your property extents on the ground to be certain.
For flood mapping please visit www.nccma.vic.gov.au/flood-eye
If you are proposing to carry out any work within the road reserve (i.e. typically outside your front fence), including driveways and drainage connections, you will require a Works Within Road Reserve Permit. Application forms and further information on this process is available here:
Building surveyors and councils won’t issue a building permit unless you have our written approval to work or build near our assets such as pipes, pits and drains.
If you are going to build, develop or renovate a property, check if there are any of our assets nearby. You can do this by checking our asset mapping at http://bendigo.pozi.com/
Don't forget to 'Dial-before-you-dig' for any excavation.
If you’re planning to build over or near any of our easements or underground assets you’ll need to get our consent before starting any work.
We generally don't allow structures to be built over our assets to help avoid any damage or community disruption. Other authorities may have to give their approval too.
Structures built near our assets must meet our standard clearance requirements and foundation criteria to protect our assets. This ensures the proposed structures and existing pipe networks are built to our standards.
Types of structures
Each application is considered on a case by case basis as there are a number of factors that may affect each application.
We will consider the construction of:
- removable carports - minimum of three open sides with flat roof
- concrete driveways and pavers
- wooden fences parallel to, or crossing our assets
We won’t allow:
- habitable structures such as buildings, extensions
- above or in-ground swimming pools
- permanent structures
- brick fences crossing any of our assets
Please not this does not preclude the need to obtain other relevant approvals and requirements.
In general structures are not recommended over easements, however, some may be approved with conditions, if the structure is non-permanent and can be fully removed.
Each application is assessed in a case-by-case basis as there are many factors to consider.
If you intend to build over an easement please fill the following application: Build-Over
The City will endeavour to work with you to resolve your drainage concern and will often go to great lengths, including video inspection of pipes, to identify the problem. If the problem is on the City network, the City will repair it. If the fault is in private property or on private drainage, it is the owner’s responsibility to repair.
If you feel strongly that the City is at fault for damage caused to your property, the City has a claim lodgement process. The relevant information is available here:
