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. The aim of an OSD system is to retain stormwater on-site during heavy rainfall and release the water slowly through a constrained outlet, limiting the peak discharge from the site to pre redevelopment levels.
An OSD system located within a development is a private asset that is owned and maintained by the owners of that development.
A retarding basin is an area of land constructed to temporarily store stormwater during a large storm, to protect drainage infrastructure and downstream properties. The basin effectively limits the peak flow, allowing the downstream drainage system to receive the stormwater flows gradually. If you notice a blockage in the outlet of a retarding basin, please call Council on 9840 9333.
Council is responsible for the maintenance and repair of open drains in areas where underground drainage is not provided. Maintenance enquiries should be referred to Council's Engineering Operations Team on 9840 9333.
Water mains are generally owned, operated and maintained by Yarra Valley Water. Should you have any emergency in regard to water flowing either on the road or into your property from a burst water main, please call Yarra Valley Water's emergency number on 132 762. Water services (pipes) within private property are the responsibility of the property owner.
Council's Drainage Engineers can investigate and if required, redesign the drainage system for increased capacity. Please call Council’s Engineering and Technical Services Unit for assistance on 9840 9333.
Residents living in areas where no sewerage is available are responsible for maintaining their septic system, so that the runoff does not cause a health hazard for surrounding residents. Residents concerned with poorly treated septic runoff from neighbouring properties should call Council's Health and Local Laws Team on 9840 9333.
All internal drainage works on private properties are the responsibility of the owner. The property owner is responsible for ensuring the stormwater pipes are well maintained and connected to Council drains. The property owner should employ a plumber or drainage contractor.
In general, your neighbour is responsible for controlling storm water 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 runoff from natural surfaces, such as grassed or treed areas, unless earthworks have been undertaken to reshape the land, resulting in redirection of flows.
Groundwater and seepage are considered natural occurrences and each property owner is responsible for making provisions to manage this water.
Drainage infrastructure can be installed to service your property through a 'Drainage Scheme.' The property owner should contact Council's Engineering and Technical Services unit on 9840 9333 for advice.
Any stormwater management system should not cause adverse effect on adjoining properties.
The builder is responsible for the drainage on building/construction sites.
A rain garden is a planted area (generally containing vegetation) that is designed to treat stormwater runoff from hard surface areas such as roofs, driveways, walkways, and compacted lawn areas. Rain gardens can help to decrease the amount of pollution reaching our creeks and streams.
Wetlands are generally built and managed to treat stormwater before it reaches our rivers, creeks and bays on a larger scale than a rain garden. Stormwater is typically polluted with nutrients and other contaminants washed from roads, gardens, nature strips and gutters. A wetland is a vegetated area of land usually covered with shallow water, which temporarily stores stormwater to allow the vegetation to remove nutrients and pollutants and improve the water quality.
