Flooding and stormwater management

We are undertaking various flood and stormwater management initiatives, aimed at building a more resilient and liveable Manningham and to facilitate robust planning for the future.

This page provides information relating to the Integrated Water Management Strategy and Manningham Flood Mapping Project.

Integrated Water Management Strategy

The Manningham Flood Mapping Project will inform the development of Manningham Council’s Integrated Water Management Strategy.

This strategy will review flooding and stormwater management risks and respond to emerging challenges, including:

  • population growth
  • development pressure;
  • climate change and associated increasing flood and drought risk.

Integrated Water Management is a collaborative approach to the way we plan for and manage all elements of the water cycle. It considers opportunities to treat stormwater as a resource, rather than a waste for disposal.

The Integrated Water Management Strategy will identify opportunities to reduce reliance on potable water, consider alternative water sources and contribute to planning for a resilient and liveable Manningham.

Manningham Flood Mapping Project

Under Regulation 148 of the Building Regulations 2018, Council is now required to prepare mapping for areas under its control that are liable to flooding.

Planned for completion in 2025, the Manningham Flood Mapping Project is being delivered by Melbourne Water and Manningham Council.

It will provide maps indicating flood extents for the regional and local drainage networks in Manningham, for a range of probable storm events.

Flood mapping involves computer modelling, which simulates how stormwater runoff travels through catchments.

Current and reliable flood mapping information is essential to understand and manage flood risk. It is used to:

  • assess the frequency, severity and location of flood risks within catchments
  • better plan and prioritise mitigation activities
  • plan for future development
  • build community awareness; and
  • inform emergency management planning.

The flood mapping process will also be informed by the latest available data and guidance recommended under the 2019 version of Australian Rainfall and Runoff.

    This National Water Week (21-27 October), we’re encouraging Manningham households to take part in Target 150.

    Target 150 is a voluntary water-efficiency initiative to get us thinking about how much water we use. It encourages us to limit our water consumption to 150 litres per person, per day.

    For most people, this means only saving another two litres of water – less than half a bucket of water a day. Simple changes to our every day habits, such as only running the dishwasher when it’s full, can help conserve water.

    Check your water bill to see if you’re hitting the target and try these water saving tips:

    • shorten your shower time by one minute
    • brush your teeth with the tap off
    • fix any leaks
    • scrape plates instead of rinsing them, before loading the dishwasher
    • place a container in the sink to catch water when preparing vegetables or washing fruit
    • use a broom to sweep the driveway, instead of using a hose.

    Melbourne’s population growth means we’ll likely need to double our water supply in the next 50 years. Our climate is changing with hotter and drier weather forecast. Climate change makes rainfall less reliable and reduces river flows.

    Melburnians are already using more water on average each year than flows into our storages, with desalinated water meeting this gap.

    Water is life and by changing behaviours to save water amongst a range of other actions, we can all contribute to the achievement of a sustainable water future.

    Water is a valuable resource and plays a vital role in connecting us all. It is fundamental to the health and wellbeing of our community, as well as the resilience and liveability of Manningham.

    National Water Week (16-22 October) celebrates water innovation and achievements supporting Australia's sustainable future.

    We are undertaking various flood and stormwater management initiatives, aimed at building a more resilient and liveable Manningham and to facilitate robust planning for the future.

    This includes developing a draft Integrated Water Management Strategy, which will identify opportunities to adapt to a more water constrained future. We’re also undertaking flood mapping for Manningham in partnership with Melbourne Water to better understand flood risk.

    Water management is a shared responsibility. To achieve greater environmental, social, cultural and economic benefits, we’re working closely with:

    • Yarra Valley Water
    • Melbourne Water
    • government departments and agencies
    • Manningham’s Flooding and Stormwater Management Community Reference Panel, and;
    • the broader community.

    Manningham Council is also a member of the Yarra Catchment Integrated Water Management Forum. The Forum provides a collaborative platform across the water industry to oversee, support and, where necessary, facilitate water’s contribution to resilience and liveability.

    We can all contribute to a sustainable water future.

    We encourage you to take a look Yarra Valley Water’s Target 155 voluntary water efficiency program. Target 155 encourages metropolitan Melbourne households to use water efficiently, aiming to limit water use to 155 litres per person per day.

    We also welcome Yarra Valley Water’s plans to address discharge from ageing septic systems, which contribute to pollution in Mullum Mullum Creek. This will improve water quality in Mullum Mullum Creek and downstream in the Yarra River. A piped sewerage system is proposed to be constructed in a key area of Park Orchards by 2030.

    Water is fundamental to the health and wellbeing of our community and the liveability of Manningham.

    Southern Australia is forecast to receive less annual rainfall on average in coming years. This will reduce water availability from water supply catchments. Water demand is also expected to increase as our City grows.

    Yet, our changing climate is also expected to bring greater intensity rainfall events, increasing our flood risk and periods of low rainfall with increased drought risk.

    We’re working on various flood and stormwater management initiatives to build a more resilient and liveable Manningham.

    Part of this work includes developing a draft Integrated Water Management Strategy. It will respond to emerging water challenges and identify opportunities to adapt to a more water constrained future.

    Earlier this year, we invited the community to take part in Manningham’s Water Future survey. Thank you to those of you who shared how you use and conserve water and why it’s important to you.

    Your responses paint a picture of a community that strongly values the Birrarung (the Yarra River) and our creeks, our environment and wildlife.

    The top three reasons why the Birrarung (Yarra River) and Manningham creeks and lakes are important to survey respondents were:

    1. They provide wildlife habitat and support biodiversity.
    2. Promote connections with nature to support mental health and wellbeing..
    3. Assist with cooling during hot weather and improve neighbourhood liveability.


    You also told us some of the ways you’re already taking action to build our resilience and conserve water.

    • 98% of respondents use front load washing machines, use dual flush toilets or only run washing machines with full loads.
    • 41% of respondents use rainwater collected from private roofs for watering gardens, toilet flushing, carwashing and other uses.
    • More than 85% of respondents also support the use of alternative water sources for garden watering, toilet flushing and laundry purposes.


    These opportunities will be a key focus of the draft Integrated Water Management Strategy, which will be available for public exhibition in mid-2024.

    E2 Design Pty Ltd, trading as E2Designlab, has been appointed to assist us in developing Manningham’s Integrated Water Management Strategy.

    An increasing population and changing climate are putting growing pressure on our water supplies.

    This strategy will review flooding and stormwater management risks and respond to emerging challenges, including:

    • population growth
    • the forecast for reducing annual average rainfall moving forward;
    • increasing flood and drought risk.


    It will identify opportunities to reduce reliance on potable water, harness alternative water sources and contribute to planning for a resilient and liveable Manningham.

    E2Designlab will assist with data gathering to:

    • inform integrated water management targets for Manningham
    • undertake investigations into potential integrated water management capital works improvements
    • provide technical advice, identify and assess opportunities to inform the development of an action plan.


    At its June meeting, Council endorsed a revised version of the Integrated Water Management Strategy Implementation Plan, including the following changes:

    • referral of some actions to now be addressed though the development of the proposed Stormwater Management Strategy.
    • updated reflection of State Government planning to advance Integrated Water Management in Victoria and the Yarra catchment including the recently received transition report.
    • updates to the project communications approach and program.


    We are also working alongside the Flooding and Stormwater Management Community Reference Panel (CRP) in the development of the strategy. The CRP has recently contributed to identifying and prioritising drivers for integrated water management for Manningham.

    Once finalised, the drivers will guide the CRP and Council in developing a draft vision for integrated water management in Manningham.

    The draft Integrated Water Management Strategy will be publicly exhibited in mid-2024, before final adoption early in 2025.
