Prospect South to Macarthur (ProMac)

Sydney Water has a long-term plan to increase resilience in our network and to extend the city’s water capacity and supply. As part of the Prospect to Macarthur (ProMac) program a new reservoir at Liverpool was constructed. 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.

Oran Park reservoir update

Since our last newsletter, principal contractor Vaughan Civil, have completed the following works at the Oran Park Reservoir site:

• Construction of two steel reinforced concrete reservoir foundations.
• Stair tower foundation.
• Installation of a piled perimeter wall.
• Pavement and sealing works.
• Topsoiling and landscaping.

A new principal contractor has been appointed,CB&I Australia, to construct the two new reservoirs. Each reservoir will hold 24 megalitres of clean drinking water and will be 21m high and 42m in diameter. The completed reservoirs will connect to the Harrington Park Pump Station.

The holiday shutdown and work resumption

Work will cease at Oran Park on Wednesday 20 December 2023 resume on Wednesday 3 January 2024. Harrington Park will cease work on Friday 22 December 2023 and resume Monday 8 January 2024. During the shutdown, all ProMac worksites will be regularly inspected to ensure temporary fencing and environmental controls are secure. If you are concerned about the condition of the site during this break, please notify the community team who will be on-call over this period.

Sydney Water would like to take this opportunity to wish everyone Season’s Greetings and all the best for a safe and happy holiday season.

Out of hours work at Oran Park reservoir

As we progress tank construction, and finalise stormwater 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.

From 2 December 2023 to 25 February 2024 extended hours of operation will be in place on Saturday and Sunday, 8am to 6pm. A notification regarding these works was distributed to Oxley Ridge residents on 25 November 2023.

Harrington Park, pump station update

Contractor Downer is finalising the construction of a new pump station in Harrington Park which will connect Narellan South Reservoir to Oran Park Reservoir to meet increased demands from growth in South West Sydney. Once in operation, the pump station will service surrounding suburbs between the two reservoirs.

In the past few months we have connected the station to the mains line, installed station doors and completed key mechanical and electrical works.

Works to come in 2024

• Flexible pavement and driveway construction.
• Stormwater drainage works.
• Security fence installation.
• Landscaping and site restoration.
• Construction of a 3m high noise wall.

When construction of Harrington Park Pump Station is complete, the team will leave the site until the Oran Park Reservoirs are constructed. A return to site will occur thereafter to complete the remaining commissioning activities, before bringing the station into operation.

Sydney Water has a long-term plan to increase resilience in our network and to extend the city’s water capacity and supply. As part of the Prospect South to Macarthur (ProMac) program we have been constructing a new drinking water pipeline, reservoir and pump station at Cecil Hills to service the Liverpool area. On the same site we are constructing a re-chlorination plant (RCP) due for completion in 2024.

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 Cecil Hills community for your continued support, patience and cooperation while we complete this essential work, to provide clean, reliable drinking water to the community.

Liverpool, pump station update

Since our August update, our Principal Contractor, Service Stream, has completed the following works:

• Commissioning activities to bring the new facility into operation.
• Testing of the pumps.
• Installation of the bioretention basin.

Service Stream have now left the site as Principal Contractor. New contractor, Ferrycarrig, is currently installing the RCP and works associated with this will continue into 2024. John Holland is also undertaking works on the northern portion of the site relating to the Sydney Water Upper South Creek Pipelines.

Fun Fact!

During construction there was 3,573 tonnes of spoil removed from the site during construction.

Restoration of the site

As ProMac work comes to an end and areas are restored, we will progressively replant to filter views of the new infrastructure and return some of the bush outlook. This work is ongoing during the construction of the re-chlorination plant. Much of this work will be dependant on species availability, weather and the appropriate seasonal planting requirements. We thank you for your patience during the restoration.

Did you know!

Once complete the new pump station is capable of delivering up to 153 mega liters of

clean drinking water to the community every day.

Re-chlorination plant

To improve the management of water quality for our customers, Sydney Water is installing a small re-chlorination plant inside the Liverpool Reservoir facility at Cecil Hills. Located towards the centre of the site, the building is made offsite and delivered as a complete unit on the back of a truck and lifted into position using a crane. In preparation for this, foundations and surrounding access roads have been constructed. This work began in September 2023 along with installation of electrical provisions and control cabling and is expected to be completed by early to mid-2024.

A re-chlorination plant automates the dosing and monitoring of chlorine into the adjacent reservoirs. The building will not be noisy when operational.

The holiday shutdown and work resumption

Work will cease on Friday 22 December 2023 and resume on Monday 8 January 2024. During the shutdown, all ProMac worksites will be regularly inspected to ensure temporary fencing and environmental controls are secure. If you are concerned about the condition of the site during this break, please notify the community team who will be on-call over this period.

Sydney Water would like to take this opportunity to wish everyone Season’s Greetings and all the best for a safe and happy holiday season.

Sydney Water has a long-term plan to increase resilience in our network and to extend the city’s water capacity and supply. As part of the Prospect South to Macarthur (ProMac) program we have been constructing a new reservoir in Currans Hill.

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 Currans Hill community for your continued support, patience and cooperation while we complete this essential work, providing clean, reliable drinking water to the community.

Currans Hill, reservoir update

Our Principal Contractor, Brockman Engineering, has been working hard to complete the Currans Hill reservoir since our August update. The reservoir is nearing completion and will be introduced into the Sydney Water network soon to further bolster water supply in the area.

Progress works have included:

• Completion of the reservoir structure.
• Installation of the roof.
• Dismantling the temporary stair platform and preparing foundations for the permanent stair structure.
• Dismantling and removing the crane affectionately named by the local pre-school children as “Pebbles”.
• Blasting the internal reservoir walls and removing the temporary coating for surface protection application.
• Application of epoxy paint to interior of reservoir to ensure years of service to the community.

Fun Fact!

It may not look like it from a distance, but this reservoir is as large in diameter as it is high (21m).

Did you know?

The inside of the tank is blasted using a magnetic robotic unit remotely driven on the interior of the reservoir, blasting the surface back to a white metal profile in preparation for the interior coating.

Works to come in 2024

The main reservoir structure is nearing completion, with only minor works taking place in 2024. These include delivery and construction of the permanent stair tower and installation of access roof hatches. As works progress to the commissioning phase, the contractor will demobilise the plant and equipment from site. The site will then be restored which includes minor restoration works on access ways and roads.

The holiday shutdown and work resumption

Work will cease at the Currans Hill site from Friday 22 December 2023 and resume on Monday 8 January 2024. During the shutdown, all ProMac worksites will be regularly inspected to ensure temporary fencing and environmental controls are secure.

If you are concerned about the condition of the site during the shutdown, please notify the community team who will be on-call over this period.

Sydney Water would like to extend to everyone Season’s Greetings and all the best for a safe and happy holiday season.

Sydney Water is 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.

As part of the Prospect to Macarthur (ProMac) program we are building two new water reservoirs in Oran Park to provide drinking water services for 84,000 new homes in the South West Growth Area, Western Sydney Aerotropolis Growth Area, Liverpool CBD and Menangle Park.

Upcoming work

Our contractor CB&I Australia are commencing construction of two 24ML steel reservoirs at Oran Park. To meet critical project milestones, we will be working extended weekend hours between Saturday 2 December 2023 and Sunday 25 February 2024 (inclusive). In addition to our standard work hours, this will involve working between 8am and 6pm Saturday and Sunday, weather permitting.

Standard work hours

 7am to 6pm Monday to Friday

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

This work will involve:

 Operation of plant and equipment to support construction of the two steel reservoirs

 Use of welding equipment, hand and power tools to fabricate steel reservoirs

 Crane lifts

Construction traffic and impacts

Light and heavy vehicles will continue to enter and exit the site via access off The Northern Road.

Use of the Southern Access Road off Brundson Road will be avoided during out of hours work where practical.

Parking of light and heavy vehicles will be confined to the construction site.

What you need to know

We know our work can be disruptive, so we’ll make every effort to reduce impact by:

 Switching vehicles and machinery off when not in use

 Placing operating plant or equipment away from the southern section of the site where possible

 Prioritise higher noise emitting activities during normal hours wherever practical

Construction works on the Oran Park site will not occur between Thursday 21 December 2023 through to Tuesday 2 January 2024.

From now through to mid December the site will be demobilised in preparation for the commissioning of the site i.e. filling the reservoir. Residents in the area may notice an increase in activity on and around the site during this period. We will continue to let you know if any of this work will have an impact on residents. In addition, we will also contact residents directly who have requested Sydney Water do so regarding upcoming works.

Upcoming work

As we enter the final stages of the works on the new reservoir in Currans Hill there will be an increase in construction traffic coming in and out of the site. Traffic will continue to use the heavy vehicle route approved by Camden Council, via Turner Road, Ascot Drive and Manooka Road (refer map below).

This work will involve:

• The demobilisation and removal of the large crane (affectionately named “Pebbles” by the local pre-school earlier this year) from the site. Due to the size of the crane a large float is required for its transport, this will enter the housing estate from Turner Road during day time hours. Residents can expect some short-term local road closures and traffic provisions in place along the route shown in the below image. We request that any traffic control measures e.g. cones, signs etc. are not moved during this period.
• Construction of the permanent access stair tower will commence late October and painting of the reservoir is ongoing through to late November, which may increase traffic volumes in the area.
• The final stages of structure testing will commence 1^st November and will last approximately six weeks. Residents may notice these works occurring between 6:00pm and 10:00pm. However, this is considered low impact work with no use of heavy plant or equipment. We expect no disturbance to local residents,

Our standard work hours

• 7:00am to 6:00pm Monday to Friday
