Prospect South to Macarthur (ProMac)

We have a long-term plan to increase resilience in our network and extend the city's water capacity and supply.

As part of the Prospect South to Macarthur (ProMac) program, since 2020 we have constructed 22 kilometres of water trunk mains, 3 pump stations, 4 new reservoirs, 5 rechlorination plants (RCP) and rebuilt the reservoir at Currans Hill.

We are pleased to advise the 6-megalitre reservoir project at Currans Hill is complete and now in operation, providing essential drinking water to the Macarthur community. Our contractors have demobilised from the site with only minor restoration work around the site to continue in November and December, followed by general maintenance.

We and our contractors extend their heartfelt thanks to the Currans Hill community for your patience and cooperation during this crucial project, especially to those residents on Manooka Road. We also appreciate the broader Currans Hill community residing on the route taken for the delivery of the stair tower, and the out-of-hours work that was necessary.

We recognise the inconvenience these operations can cause and are grateful for your support. We would like to take this opportunity to wish you and your families well for the upcoming festive season and new year.

Stay safe and be water wise.

As part of the ProMac program, we have now completed construction of two 24-megalitre drinking water reservoirs at Oxley Ridge Cobbitty (Oran Park Reservoirs).

The final preparations for filling the reservoirs and demobilising from site is now underway. Testing, cleaning and disinfection of the reservoirs is currently occurring on-site to enable the reservoirs to be filled with clean drinking water. Minor civil and restoration work is also being undertaken around the site and will continue into 2025.

Reservoirs out-of-hours work – 24/7

From Wednesday, 4 December 2024 to Friday, 20 December 2024 we will commence filling the 2 reservoirs. Filling will be assisted by the booster pump located on the corner of The Northern Road and Brunsdon Road, Cobbitty (corner of Oxley Ridge Estate).

Christmas shutdown period

Our reservoir construction team will close the reservoir site from 20 December 2024 to 5 January 2025, resuming work on 6 January 2025. No work will occur during this time.

While we do our best to minimise the impact on the community, we do appreciate the work we do can impact some more than others. We thank the Oxley Ridge and Oran Park communities for your patience and cooperation as we build this critical infrastructure.

We take this opportunity to wish all of the community a safe, healthy and happy holiday season.

As part of the ProMac program, we have finished constructing a new drinking water pipeline, new reservoir, pump station and rechlorination plant (RCP) at Cecil Hills to service the Liverpool area.

We're pleased to advise the landscaping and restoration work on the Liverpool pump station (Cecil Hills) site is finished. The landscaping contractor will maintain the site to ensure the grasses and saplings planted thrive. Mowing and weed maintenance will be ongoing by the Sydney Water team.

Sydney Water takes this opportunity to sincerely thank the Cecil Hills community for your patience and cooperation while we undertook this vital work. Particularly those residents bordering our site in Stein Place, Davina Crescent, Earl Place, Edinburgh Circuit and Louise Place.

We're working to expand our network to meet increased demands from growth in South West Sydney, ensuring our existing and future customers continue to have reliable access to clean drinking water.

To service the ongoing development within Western Sydney including the Western Sydney Airport (WSA), a new trunk water main is being constructed from Western Road, along Overett Avenue under South Creek to Martin Road, and onto the WSA site at Badgerys Creek, along Elizabeth Drive.

Work is about to commence on the eastern verge of Martin Road, near the intersection of Elizabeth Drive at 10 Martin Road. This will involve the construction of a microtunnel pit. To avoid road closures and maximise the safety of our construction team we will be working nights and all day Saturday and Sunday this week.

Upcoming work – out of hours

• Monday 19 August to Saturday 24 August 9pm–5am (night crew)
• Saturday 24 August and Sunday 25 August. 7am–8pm (day crew)

Our standard work hours are:

• Monday to Friday 7am–6pm
• Saturday 8am–1pm

This work will involve:

• Construction of the microtunnel receival pit.
• Positioning of pipes along roadside verge on Martin Road.
• Excavating machinery, trucks and other heavy equipment will be in the area.
• Lighting and safety controls will be in place. Traffic control measures will also be in place.
• We predict this work to be noisy and every effort will be made to minimise disruptions to the area.

We have engaged ACCIONA as Delivery Partner and representatives of Sydney Water. Athassel Civil Pty Ltd is the principal contractor for this work. If you have any questions or require further information, please don't hesitate to contact our Community Engagement Manager, Julie Adams, promac@sydneywater.com.au 1800 678 098.

Thank you for your understanding and cooperation during this important work.

Further to our notification in July, we can now confirm the 4 sections of the stair tower for the Currans Hill Reservoir will arrive on Monday 19 August at 5am.

As the stair tower is oversize, two 40-foot semi-trailers are required to deliver it to site outside peak hours to minimise impacts on traffic. Four wide load escort vehicles will also accompany the semi-trailers.

An approved traffic route issued by Camden Council is included for your reference. All appropriate out-of-hours permits have been lodged and approved by Transport for NSW and Sydney Water.

We ask all residents who live on the approved route to consider the following on Sunday (18 August) night:

• Avoid street parking where possible.
• Street parking should avoid vehicles parking opposite (parallel) another vehicle. As mentioned, the 2 trucks are wide loads, 2 vehicles parked on either side of the road will prevent the trucks access. Please stagger vehicles or park on the same side of the road, particularly those residents in Manooka Road.

Out-of-hours delivery:

• The complexities of this delivery require an out-of-hours delivery to site in Manooka Road at 5am. Residents in Manooka Road may notice some noise associated with the trucks arrival and delivery to site. We will do our best to minimise noise and light disturbances.
• Site managers will be placing traffic cones where possible along the route on Sunday evening to avoid cars parking in those areas. Please do not remove these cones and make alternative arrangements to park your vehicle.

This work will involve:

• Light vehicle movements.
• Light tools and generators in use.

Construction traffic and impacts:

• The works are not expected to impact the current motorists, cyclists or pedestrians on the Northern Road or nearby housing estates.

What you need to know:

We know our work can be disruptive at times so we’ll make every effort to minimise disturbances by:

• Turning off all vehicles when not in use.
• Completing the noisiest work during standard hours.

To do this, we are planning to provide new and upgraded drinking water services to both residential and commercial areas within the Western Sydney Aerotropolis Growth Area (WSAGA).

To service the ongoing development within Western Sydney including the Western Sydney Airport (WSA), a new trunk water main has been designed to run from Western Road, Kemps Creek, to the WSA site at Badgerys Creek.

Works will include:

• Service locating the alignment to verify design information
• Installation of new DN750 watermain along Overett Avenue and Martin Road
• Horizontal Direction Drilling under South Creek and Badgerys Creek

Micro-tunnel crossing of Elizabeth Drive.

Horizontal Directional Drilling (HDD) early works commenced along Elizabeth Drive, Badgerys Creek in November 2023. The next stage of the project is due to commence mid May. During this time, residents in Overett Avenue and Martin Road will notice an increase in construction traffic, with traffic controls being used to ensure a safe environment for work crews and road users.

We have included below an indicative aerial map of where the pipeline will be delivered. If you have any questions or enquiries, please contact the ProMac Community Team on 1800 678 098.

The main focus has been on internal tasks, with electrical and cable work nearing completion, to be succeeded by HV electrical energisation and commissioning activities. Moreover, the installation of the permanent noise wall is complete, in the community favored “monument” colour has been successfully finished.

Civil works have commenced to finish the carpark and access driveways as well as landscaping at the rear of the site. Although there are remaining tasks, we anticipate completion by end May.

Landscaping plans

Planning is underway to restore this site. Once a landscaper and design is finalised we will inform the Harrington Park community accordingly.

When construction of Harrington Park Pump Station is complete, the team will leave the site until the Oran Park reservoirs are constructed. They will then return to complete the remaining commissioning activities, before bringing the station into full operation.

As part of the Prospect South to Macarthur (ProMac) program we are currently constructing two 24 megalitre water reservoirs at Oran Park and a rechlorination plant.

When complete the reservoirs will hold equivalent to 50 olympic sized swimming pools. They will be connected to the new pump station at Harrington Park to increase supply to the Macarthur region.

While we do our best to minimise the impact on the community we do appreciate the work we do can impact some more than others. We thank the Oran Park and Harrington Park communities for your patience and cooperation.

Oran Park out of hours work

As we progress tank construction we will continue to occasionally work outside of our standard hours. Standard work hours are:

7am to 6pm Monday to Friday

8am to 1pm Saturday. We will not work on Public Holidays.

Currently extended hours of operation are in place on Saturday 1pm to 6pm and Sunday, 8am to 6pm until 27 October 2024.

Cecil Park reservoir was refurbished and upgrade works are now complete and two new reservoirs at Oran Park are under construction, to allow for a total of 100 megaliters of additional reservoir capacity. That’s equivalent to about 50 olympic-sized swimming pools!

Whilst we do our best at Sydney Water to minimise the impact on the local community, we appreciate the work we do can impact some more than others. We thank the Oran Park and Harrington Park communities for your continued support, patience and cooperation while we complete this essential work, to provide clean, reliable drinking water to the community.
