Manningham Council adopted its Drainage Strategy in 1994 and Stormwater Management Plan in 2001, and both are reviewed regularly. The aim of these strategies is to improve the drainage system and the quality of stormwater discharging into creeks, streams, rivers and wetlands in Manningham.

One of the major issues identified in the Stormwater Management Plan is the amount of litter, including cigarette butts, cans and food wrappings entering Council's stormwater drains and discharging into local waterways such as the Koonung Creek. It is estimated that the amount of litter entering Port Phillip Bay each year from waterways that drain to Port Phillip Bay could fill the Melbourne Cricket Ground four times over.

Excessive stormwater run-off from urban catchments with large areas of impervious surfaces (for example, concrete, roads and roofs) contributes to pollution and degradation of our waterways. Council is working with Melbourne Water and Monash University to develop solutions to managing stormwater. Council also checks underground on-road and easement drainage systems once a year for blockages. Any blockages reported by residents, ie. blockages caused by tree roots, are also cleared regularly.

The Icon for application/pdf Manningham City Council - Standard Drawings (6.99 MB) set out the required technical details for road pavement, kerb and channel, drainage pits, and associated infrastructure for Council assets within the City of Manningham. Proposed assets within the City are to comply with these standards.

Stormwater Connections

Point of Discharge

An application for a Point of Discharge must be made to Council 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 be required to be directed to the point of discharge for the property.

Approval for Connection to Council Drain

A Council permit is required, prior to 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 must arrange an inspection by Council’s representative, at least 48 hours prior to the proposed inspection date.


Manningham Council has adopted the use of On-Site Stormwater Detention (OSD) systems to better manage stormwater runoff from higher density development.

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

OSD systems may be required as a condition on a planning permit and have the potential to minimise local flooding and decrease the peak flow rate to drains and waterways.
For more information:

For more information on designing an OSD system, view the Icon for application/pdf onsite stormwater detention guide (2.37 MB), call 9840 9333 or use our online service request form.

Building over Easements

Easements on private property exist to service drainage, sewerage etc on the land. Private construction over a Council easement requires approval and in some cases, Council may not give its approval.

People are encouraged to view Icon for application/pdf Application to Build Over an Easement and Policy (180.1 KB) before making an application.
