    Introduction
    Domestic wastewater as defined within
    the Environment Protection Act 1970
    means ‘any waste containing human
    excreta or domestic wastewater’.
    This means any wastewater from the toilet, bathroom, kitchen or laundry of any premises
    that generates up to 5000 litres of wastewater per day.
    Domestic wastewater management systems can include septic tanks, aerated wastewater
    treatment systems, composting toilets, sand filters, reed beds and wetlands. Well
    maintained wastewater systems provide a viable, often cost-effective and sustainable
    alternative where reticulated sewer is not available. However, wastewater systems that are
    poorly operating or inadequate, can pose a serious risk to human health and the
    environment. More specifically, the risks associated with wastewater include:

     Maroondah in Context
     The City of Maroondah is located within the eastern suburbs of Melbourne and covers an
     area of approximately 61.4 square kilometres. The area is a substantially developed peri-
     urban residential municipality, with an estimated population of 113,944 residents and
     44,227 households with an average of 2.58 people per household.

     Map of Maroondah

     Maroondah is well known for its leafy streets, broad areas of open space, bushland
     reserves, parks and playgrounds. Sustainable transport links include on-road cycling paths
     and shared path links to the Mullum Mullum Creek Trail, the EastLink Trail, Taralla Creek
     Trail and the Dandenong Creek Trail.
     Maroondah’s natural environment is highly valued and our green character is treasured by
     locals. There is a strong desire for our green open spaces and bushland reserves to be
     enhanced and protected.
     Mullum Mullum Creek and Dandenong Creek are the major waterways in the Maroondah
     area, with established recreational routes that are well utilised. The waterways within
     Maroondah also drain to two of Melbourne Water’s main catchments - Dandenong Creek
     and Yarra River which are enjoyed by a broader community, and therefore need to be
     carefully managed.

Maroondah’s Domestic
Wastewater Management
Profile
There are 158 domestic wastewater
management systems within the
municipality.
This was determined through cross-referencing data provided by Yarra Valley Water,
Council records, and inspections of properties. Figure 1 provides an overview of the pocket
areas of wastewater systems in Maroondah.

There are also approximately 20 vacant properties in these areas that do not have an
available connection point to sewer. Table 1 provides a breakdown of the number of
properties with wastewater systems for each suburb in Maroondah and the number of
properties on the community sewerage program.

        These systems include septic tanks, aerated wastewater treatment systems (AWTS), sand
        filters, greywater treatment systems and worm farms disposing to underground trenches,
        subsurface irrigation and discharging to stormwater (figure 2). Of the 158 properties
        serviced by a wastewater system, Council has no records for 63 properties. This could be
        due to installation prior to Council’s record keeping or due to amalgamations*.
        *Note: this is consistent with the findings of the Victorian Auditor General (2006) report.

        Council records indicate that 49 properties that utilise onsite wastewater management
        systems are not identified in YVW’s Community Sewerage Program.

     Risks associated with domestic wastewater for Maroondah
     From the 1950s, wastewater systems were used and continue to be used extensively
     throughout Victoria in areas not serviced by reticulated sewerage. Wastewater systems are
     an acceptable solution to treat domestic wastewater provided the wastewater is contained
     and disposed of effectively onsite.
     In the past, wastewater systems were a key contributor to the increasing pollution of
     Melbourne’s rivers and creeks that threatened the health of Port Phillip Bay. Wastewater
     from domestic wastewater management systems, seeps into stormwater drains, waterways
     and groundwater whilst also polluting soils and increasing the risks to public health,
     environmental health and creating detrimental effects to the local amenity.
     Maroondah City Council has a responsibility in ensuring the risks associated with domestic
     wastewater are appropriately managed. From the workings undertaken as part of the
     domestic wastewater management project, the risks identified for Maroondah include:
     Public health risks                                    Legal risks

14      Domestic Wastewater Management Strategy 2017-2021
Our strategic response
Our vision
The vision of this Domestic Wastewater Management Plan is to:

“Protect public health, the natural
environment and the amenity of the
municipality by promoting environmental
best practice in the management of
domestic wastewater”
Future outcomes
To achieve this vision, we will work towards three key outcomes in order to promote
environmental best practice in the management of domestic wastewater. These outcomes
have been developed through extensive research of industry best practice, from the work
carried out throughout the wastewater project, and legislative requirements. The key
outcome areas align with the Water Sensitive City Strategy (2016).
They are:

                                      Outcome 1

                                    Healthy

      Our journey so far
      Council’s Wastewater Project Officer has attended all properties that are serviced by a
      domestic wastewater management system in Maroondah. An inspection of the system was
      carried out to determine how well the system is operating, the location of the disposal
      area and to discuss any concerns the owner may have with the system. Systems that were
      found to be operating outside of their permit or the EPA guidelines were required to
      rectify the issue. Each property owner was provided with information on how to effectively
      maintain their system.

18      Domestic Wastewater Management Strategy 2017-2021
Our journey so far
In 2016 Council provided a submission to YVW as part of their Community Sewerage
program prioritisation process. This included recommendations for the inclusion of a number
of properties considered as high risk that are not in the current Sewerage program.
Through this project a new referral process has been implemented internally within Council
to ensure wastewater is captured as a key element to new and existing developments in
areas not connected to sewer. The Wastewater Project Officer and Environmental Health
Officers have provided their technical expertise to other Council departments to raise
awareness of these issues.
