Frequently Asked Questions
Project information
Which properties will be serviced by this work?
The new reticulation network will service approximately 280 properties in Menangle village, including the Durham Green Retirement Village. This includes properties south of Station Street and west of the railway line.
When will this work be delivered?
Timeframes for the delivery of this work will be confirmed after the business case has been approved and further investigations are completed.
Menangle was included in the NSW Government’s Priority Sewerage Program (PSP). Will these services be delivered under the PSP?
Sydney Water’s Operating Licence sets out the standards and requirements for us to provide our services. Our new Operating Licence 2024-2028 came into effect on 1 July 2024 and does not include any requirements relating to the Priority Sewerage Program. Therefore, the Menangle Wastewater Servicing project will not be delivered under the PSP. Instead, Sydney Water will deliver this work as part of our servicing strategy for the Greater Macarthur region.
What impacts will there be to property owners?
In the next stage of the project, we will inform individual property owners about any potential design and construct impacts from this work.

Why has this design been chosen?
Sydney Water investigated multiple designs for a wastewater reticulation network in Menangle village. We reviewed each of the design options and chose our proposed design after considering both financial and non-financial factors including:
We have chosen the proposed design as it is the most cost effective and has the least construction risks.
Why does the proposed design use both gravity system and pressure sewerage system?
The proposed wastewater reticulation network to service Menangle village uses mostly gravity system where topography and ground conditions have allowed. In some parts of the design, we are proposing to use pressure sewerage systems due to more challenging topographical conditions.
What is a gravity wastewater system?
A gravity wastewater system is a type of wastewater system that relies on gravity to transport wastewater.
In a gravity system, the pipes have a gradual slope which allows wastewater to flow naturally downhill away from properties and into the network. The network then ultimately transports wastewater to a facility for treatment.
Gravity systems are the most conventional type of wastewater system used.
What is a pressure sewerage system?
A pressure sewerage system is a type of wastewater system that uses pressure to transport wastewater.
This type of system uses a collection tank, pumping unit and sealed pipe installed at each property to transport wastewater from the property to the network. The collection tank holds the property’s wastewater, and the pump pushes the wastewater from the tank through the sealed pipe and into the network. The network then ultimately transports wastewater to a facility for treatment.
Pressure sewerage systems are generally used in areas where a conventional gravity system is not a viable option. For example, pressure sewerage systems may be used in areas that are flat, wet, rocky, hilly terrain or environmentally sensitive.
