Prospect South to Macarthur (ProMac)

On Saturday 30 October, the first connection was made between the newly completed pipeline in William Howe Regional Park, and the existing network which feeds into the Narellan South Reservoir in Mount Annan. There will be multiple points of connection following this event, with the next to occur in just over two weeks time.

To complete the connection, Sydney Water shutdown the reservoir for 24 hours from 7 am on Saturday. This involved closing the valves and flushing water from the existing main. The connection was made without affecting the water supply for Sydney Water customers. It took one hour for the existing capped end to be sawed open, with an additional 4 hours spent welding a new flanged rim to the existing end. The final fitting of the new pipeline was then lifted into position and bolted to the existing main.

The ProMac team has kept the Mount Annan community up to date with the progress of works in William Howe Regional Park. Prior to the connection works commencing, the 12 properties within 100 metres of the works were doorknocked so the team could explain the proposed activities and answer any questions.

This area of pipeline is just one of 18 packages of work within the Prospect to Macarthur (ProMac) program. To date, our contractor Vaughan Civil has installed around 50 percent of the 4,379m pipeline in Menangle Park, William Howe Regional Park and Australian Botanic Garden in Mount Annan.

As part of the Prospect to Macarthur (ProMac) Program, we recently completed the refurbishment of the existing 30 megalitre reservoir at Cecil Park. The timing of these works was planned in 2020 to coincide with lower water demands by our customers during a late autumn / winter / early spring shutdown.

These works were delivered on time and are now ready for the peak summer demand period. The scope of works included structural upgrades to the reservoir roof and replacement of the existing internal bitumen lining with a durable epoxy paint. Roof repairs encompassed a 50% replacement of sheeting and steel repairs to beams. Other additions include new hatches, ventilation and divers’ ladders.

Cecil Park Reservoir is connected to the new water trunk main currently being installed from Liverpool reservoir to Kemps Creek and will meet the increased demands from growth in South West Sydney and the new Aerotropolis.

As part of the Prospect to Macarthur (ProMac) project we are upgrading the existing reservoirs at Liverpool and Cecil Park as well as building two new reservoirs at Oran Park to allow for a total of 100 ML of additional reservoir capacity.

We are also upgrading the existing water pumping station inside Prospect Reservoir to provide drinking water services for 84,000 new homes in the South West Growth Area and Western Sydney Aerotropolis Growth Area.

As part of these works, we will be installing an air valve on the corner of Twenty Fifth Avenue and Twenty Sixth Avenue in West Hoxton which will release any built-up air in the drinking water pipeline. This air valve will ensure the performance of the pipe is maintained. Works will begin on Monday 18 October 2021, expected to finish by the end of October 2021, weather permitting. There will be an interruption to water supply during the final stages of work. Residents will be notified before this occurs.

Work will involve:

We are installing 26 cathodic protection pits and test points along the verge of Cross Street and Western Road. Cathodic protection is a system used to extend the life of the steel water main by minimising corrosion of the pipe. This requires installing sacrificial metals (anodes) alongside the pipeline which corrode at a faster rate than the steel main. These anodes are attached to the pipe with cables which lead up to an above-ground test point mounted on a pole and a cabinet (see image below).

The work will be happening in localised areas between Monday 11 October and Saturday 30 October 2021, weather permitting.

During the works there will be changes to traffic conditions on Cross Street and Western Road. Lane closures and traffic control will be in place to safely assist motorists around our work areas. Please see map below for location of work.
