Wyee Sewer

Hunter Water is pleased to announce the commissioning and availability of sewer connections as part of the Wyee Sewer Scheme, from 1 June 2021.

We acknowledge that we have experienced challenging conditions and significant wet weather during the construction period, and we sincerely appreciate the Wyee community's patience, cooperation and understanding over this time.

What this means for property owners

Property owners (or their licenced plumber) will be able to make an application to connect to the Wyee sewer network from 1 June 2021. For ease of service and to help you navigate through this process, we recommend you read our step by step guide, to ensure your connection meets Australian Standards and Hunter Water's requirements.

Throughout the coming months you will still see our contractor continuing to work in the area to complete any remaining restoration works.

Understanding and starting the connection process

We previously provided property owners with a connection booklet which outlines the process you need to follow in order to connect to the new sewer system. We encourage you to familiarise yourself again with this booklet.

We recommend that you submit an application after you have appointed your preferred licenced plumber. Your licenced plumber may also submit an application directly to Hunter Water on your behalf. For ease of service and for efficient processing, we encourage you to make an application via the form on our website. Hard copy applications will also be accepted. If you are having issues with completing or submitting the application please call 1300 657 657 to speak with a friendly customer service representative.

Locating your sewer connection

Your sewer connection has been marked on your property with a white peg in the ground (or a paint mark), and should be consistent with the tailored home plan that has been provided to you by the contractor, Monadelphous. If you are unable to locate the white peg, have removed your peg and/or remain unsure of your property connection location, please contact Hunter Water.

If your licensed plumber is unable to locate the connection point, we request they dig one metre either side of the expected connection location to a depth of 1.5 metres. If after doing this they are still unable to locate the connection or it is found to be faulty, your licensed plumber should contact Hunter Water on 1300 657 657 (available from 8am to 5pm weekdays) for assistance.

Hunter Water and Monadelphous (our authorised contractor) are working through the challenges of prolonged wet weather and difficult subsurface conditions to finalise the Wyee Sewer Scheme ready for connection.

Since September 2019 ongoing rain events have impacted the project, with more than 170 days of scheduled work being delayed due to wet weather events. Wet weather disrupts work for a number of days following each rain event, while clean up occurs and groundwater subsides from excavations. Due to the very high groundwater tables in some areas of Wyee, it can take weeks for works to recommence.

Due to the ongoing weather and site impacts, along with the recent severe weather, the project’s completion date has been delayed. Commissioning is now expected before the end of May 2021 (subject to future weather conditions).

Hunter Water will formally notify the community with written correspondence once the new sewer system is available for connection and/or if any changes to the connection process emerge.

In order to help Wyee residents prepare for the commissioning and connection process, we have organised a drop in session for those that would like a face to face discussion.

Date: Tuesday 23 February 2021
When: Between 1 - 4pm (drop in any time that suits you)
Where: Wyee Community Hall, corner of Wyee Rd and Hue Hue Rd, Wyee

In attendance will be representatives from Hunter Water, Lake Macquarie City Council and Monadelphous. This will be an opportunity for the community to ask any questions they may have in relation to the final stages of the construction, decommissioning your existing septic system and connecting to the sewer system.

This information session will be held in a COVID-19 safe way. Our aim is to ensure that this information session is being conducted in compliance with the current Public Health Order (PHO) requirements. All attendees must record their name, mobile number or email address on the day. Records will be only used for the purpose of tracing COVID-19 infections and will be stored confidentially and securely.

The NSW Government and Hunter Water funded Wyee Sewer Scheme is nearing completion, with the first stage of construction to provide sewer services to properties in the Wyee township in its final stages. Hunter Water will formally advise customers when they are able to connect to the system, however it is still likely to be March 2021.

System testing is underway

The system has been tested at connection points and between manholes. Once the pump stations are complete, the whole system will be tested prior to commissioning. The testing may lead to additional work during the commissioning phase of the project.

Second stage of the scheme

The second stage of the scheme will be the transfer main from Wyee to Morriset. This will transfer the sewage to the Dora Creek Wastewater Treatment Facility. Works will commence on this pipeline mid-2021 with completion expected mid-2022. During this construction Hunter Water will be tankering the wastewater out of Wyee.

Connecting to the sewer booklet

In December 2020 our team hand delivered a ‘connecting to the sewer’ booklet outlining the steps Wyee property owners need to take to connect to the sewer system. You can also download the booklet here.

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).
