Stormwater connections

Depending on your specific circumstances there are different types of applications that need to be made. We encourage applicants to contact Council’s engineering department on 9840 9333 to discuss as we would much prefer to receive the correct information upfront.

Council has standard drawings that cover the majority of situations and can be downloaded Icon for application/pdf Manningham City Council - Standard Drawings (6.99 MB).

All applicants should be aware that there is some basic technical information that must be provided in order for an application to be processed, and include:

  • Confirmation of connection levels into Council drains
  • Design parameters
  • Confirmation that the correct fee has been paid
  • Where the application relates to Planning approval confirmation that the design is in accordance with endorsed plans

Point of discharge applications

You need to apply for a point of discharge when a building permit is required for a development which includes a stormwater drainage system.

The point of discharge will be used in the design of the drainage for the site. Stormwater discharge from any part of a roof, paved or impervious area will need to be directed to the point of discharge for the property.

Single dwelling approval for connection to Council drain

You will need a permit before connecting a drain on private property to a Council drain. Council drains include underground drains, which share a common boundary with roads or are located within easements on private property.

The permit holder is responsible for arranging the works and necessary traffic management, (if the work is within the road reserve) and restoring the land to its original condition to the satisfaction of Council’s representative.

The applicant will need to arrange an inspection by Council at least 48 hours prior to the proposed inspection date.

You can apply online for a connection for a single dwelling into Council drain.

No Council drainage system?

Drainage infrastructure can be installed to service your property through a drainage scheme. For more information, call our Engineering and Technical Services unit on 9840 9333 for advice.

Any stormwater management system should not cause adverse effect on adjoining properties.

Development drainage

What is On-Site Stormwater Detention (OSD)?

New developments in Manningham, particularly unit developments, are increasing hard surface areas, resulting in a higher volume of stormwater runoff discharged into our existing drainage system. An OSD system is required as part of the planning process when the existing drainage system cannot cope with the increased runoff. An OSD system helps retain stormwater on-site during heavy rainfall and releases the water slowly through a constrained outlet, limiting the peak discharge from the site.

How do I apply for an OSD approval?

Any developments within Manningham that may increase stormwater runoff are generally required to construct an OSD system.

When you apply for approval of an OSD, approval is also required for connection into Council drains.

I need to make changes to OSD plans

You need to complete a Public Works (Outfall drain) and OSD Amendments application when you want to make changes to the existing engineering plans. This application also needs to be completed for the construction of an outfall drain and or general drainage works. Revised engineering plans need to be submitted to us for re-approval and we may need to inspect the site again.

Report and consent of Council

You will need to apply for a report and consent if the property is located in an area liable to flooding, or if you are constructing a building on ‘designated land or works’.
