The design of the Lilydale Community Sewerage area is progressing well and we expect to start construction in 2024.

We ask residents in the program area to respond to correspondence sent this month:

Gravity sewer customers: need to let us know that they approve the proposed connection point location on their property.

Pressure sewer customers: need to book an appointment with Pressure Sewerage Services Australia (PSSA) to determine the location of the equipment on their property. 

Not sure or have questions? Please contact our team on 9872 2551. 

What’s happening in your neighbourhood this year?

We'll be undertaking investigative work in Lilydale this year. It involves:

• Surveying and assessments – our surveyors and engineers will be walking around the area doing general surveying, reviews and assessments.
• Service locating – we’ll be using ‘non-destructive digging’ to find existing power, gas, telecommunications, water and sewerage services in the ground. This investigation work involves ‘digging’ into road reserves and pathways using a high pressure water to dislodge soil. Using this equipment minimises risk of damage to existing pipes and infrastructure, as well as tree roots and vegetation. 
• Geotechnical sampling – small bore holes are drilled in different areas and soil and rock samples are analysed to help decide the best location for the sewerage pipes.
• Cultural heritage investigation – to assess the potential impact of any proposed activity on Aboriginal cultural heritage. This is part of a Cultural Heritage Management Plan required under the Aboriginal Heritage Act 2006.
• Ecological and tree surveying – to help determine the route of our pipelines, reduce the need to disturb vegetation and to protect the environment.

We'll use this information to refine our engineering plans for the sewerage system and prepare for construction in 2023. 

How will the works affect local traffic?

The geotechnical surveys will involve some temporary road closures, speed reduction and detours in the area.

The investigations will be done progressively, and we’ve planned the works to minimise disruption for residents and visitors to the area. 

Our contractors and traffic management will work closely with you to keep you moving.

What can I expect during these investigations?

You may notice:

• Extra vehicles in the area.
• Some noise from drilling equipment and machinery reversing and using beepers for safety. 
• Some paint or chalk markings on the ground.
• Our staff and contractors walking around the area and looking into individual properties.

Your water supply and pressure will not be affected during the works.

We’re continuing work on the design of a piped sewerage system for Lilydale, recently completing a site walk to progress the engineering of a sewerage system suited to the area.

We expect the new sewerage system to be available in early 2024.

We encourage you to continue maintaining your existing sewerage system, and we’ll provide further updates as we progress.

Over the past 12 months we have reviewed the sewerage service needs of properties in unsewered parts of Lilydale and captured feedback from property owners.

The initial design, presented to the community at an information session in October 2017, provided sewer connections to properties that were unable to contain wastewater within their boundary. This was approximately half of the investigation area.

Following feedback from the community, we have revised our service delivery approach and will provide sewerage connections to all properties within the investigation area. The properties impacted by this decision are shown on the Lilydale Sewerage Project area map.

We will now need to undertake additional work which will delay the delivery of this project. We expect the new sewerage network will be available in 2023.

We encourage you to continue maintaining your existing sewerage system and apologise for any inconvenience.
