Wyee Sewer

Hunter Water and Monadelphous (our authorised contractor) are currently finalising the construction of the Wyee Sewer Scheme.

This has been a significant project and we would like to sincerely thank the Wyee community for working with us during the planning and construction phases. Your cooperation and understanding has been very much appreciated while we move through the complexities of constructing sewer in a built up area.

The project has been impacted by both large rain events and COVID-19 restrictions. We were hoping to be in the testing phase by now to enable connections to the network by the end of the 2020 however construction of the pumping stations is still progressing. Once construction is complete we will be testing the entire sewer network to check for leaks and defects. It is important that no one connections to the system until this testing is complete. Currently completion of testing is expected end of February 2021, pending further delays.

In the coming weeks the Wyee Community will receive further information from Hunter Water explaining the connection process. This will include advice on engaging a plumber and getting quotes, disconnecting your septic tanks and applying to Hunter Water for a connection.

Monadelphous will also continue to be distributing construction updates and information to residents for the duration of the project. Monadelphous can be contacted via their 24 hour hotline on 1800 450 500.

Despite the challenges raised by the COVID-19 pandemic, our contractor Monadelphous has now completed 70 per cent of the Wyee pipeline work, having laid more than 8km of the 11km network.

The construction crews have been practising social distancing on the work site and during meetings with landowners. They’re now continuing these practices as they work in Jilliby Street, Wyee Road, Bukkai Street, Munmorah Street, Wallarah Street, Boikonumba Road and Summerhayes Road.

Construction of the pump station in Wallarah Street is also underway. Once operational, it will store the South section of Wyee's sewerage below ground and then transfer it to the second pump station on Karagi Street.

In the coming months, surveyors will be visiting almost every street in the project area to complete final surveying and pipeline testing. Restoration works will occur once construction is complete and testing has occurred.

While we have encountered some difficult site conditions in the last few months, the work remains on track for completion in December 2020.

A massive thank you to Wyee residents for your continued patience and cooperation as we work to deliver this important project in your area.

Get in touch

For enquiries and feedback about the Wyee sewer construction work, please call our community team on 1800 450 500.

Hunter Water's contractor, Monadelphous, are making great progress on the Wyee Sewer construction. Over 4km of pipe has been laid out of the 11km network, and we are on track for commissioning the system in December 2020.

Work has also begun at the two pump station sites, with the activity scheduled to increase in the coming months.

While we have received some much needed rain over the last few months, unfortunately some issues arose with driveways and streets that the contractor had been working in. Monadelphous have been working hard to restore any damage and property owners are encouraged to contact them if they have any concerns (1800 450 500).

Hunter Water will be doing more sewer connection education closer to the commissioning date, and will be in touch with property owners.

A big thankyou also to all of the Wyee residents and property owners for working collaboratively with us and being patient through such disruptive construction.

We’re holding another community drop in session to answer any questions about project construction, how it affects residents and how to go about connecting to the new system.

Date: Thursday 21 November 2019
Time: Between 2:30 – 5:30pm (drop in any time that suits you)
Location: Wyee Community Hall, corner of Wyee Rd and Hue Hue Rd, Wyee

Subject matter experts from Hunter Water, Monadelphous and Lake Macquarie City Council will be on hand again to answer any queries about the following topics:

• Construction timeframes and methodology
• Impacts to properties and locations around the town
• Licences to work on private property
• Sewer design
• Issues, complaints or questions during construction
• The process of connecting to the system once complete
• Decommissioning existing systems (septics, etc.)
• Stormwater related issues
• Project area plans for the future
• Restoration works

The Wyee Sewer project construction phase commenced on Monday 2 September 2019.

As you may know, Monadelphous is working on behalf of Hunter Water to construct the new sewer system and pump stations that will service over 400 properties in the Wyee township. Residents can expect to see our crews around the town until the completion of the project at end of 2020.

As of early October, over 500m of pipe has been laid, crews are increasing in number and progressing through the south Wyee area (zone 3).

Hunter Water is happy to notify Wyee residents that we are progressing through the detailed design phase with our contractor Monadelphous, and the construction schedule is on track to commence at the end of July 2019.

Hunter Water is pleased to announce that the Wyee Sewer Scheme project has now progressed to the detailed design and construction phase. This week, Monadelphous Engineering Pty Ltd was awarded the contract to construct the sewer infrastructure to service the Wyee Township on behalf of Hunter Water. Monadelphous brings extensive experience in water-related infrastructure, recently completing projects on behalf of Sydney Water.

Key dates

With the contract now awarded, work will progress immediately on the detailed design of the system. The design process is expected to be complete by September 2019.

Monodelphous will establish on site in June 2019 ready to begin construction. Construction will take approximately 18 months to complete (depending upon weather and any other unforeseen circumstances).

We expect you will be able to connect to the new sewer by December 2020.

Design process

Detailed design is the process of developing and finalising the approved concept design. It will confirm exactly where each component of the new sewer scheme will be constructed and will give us a clearer view of the full impacts of the project and how Wyee residents may be affected by the work.

During detailed design residents may notice contractors inspecting the various locations where future construction may take place. We may need to access some private properties to complete this work, and we will contact the property owner if we need to arrange entry to a property.

Shortly we will award the contract for detailed design and construction of the new sewer system in Wyee.

Once the contractor is announced, the team will establish a site office in Wyee and progress with the detailed design.

The project site office will offer a point of contact for residents to ask questions about planned works near their home, learn about upcoming works and raise any concerns they may have. This dedicated team will provide day-to-day support to the project and community as detailed design is finalised and construction progresses over the next two years.

Early construction work has begun ahead of schedule for the $30 million Wyee Sewer Scheme, as Hunter Water and Lake Macquarie City Council work together to coordinate two community projects and minimise disruption to local residents.

While the main work in Wyee is on track to commence in mid-2019, early work is underway at Morisset to install 500 metres of pipework along Macquarie Street. This will connect the town to Hunter Water’s existing wastewater network and should take approximately 12 weeks to complete.
