Smalls Creek carrier duplication

Supporting the growing community

We're installing a new wastewater pipe along Smalls Creek in Kellyville to support the growing community.


About this project

We're installing a new wastewater pipe along Smalls Creek in Kellyville to support the growing community. This is one of several projects that will help service growth in the Metro North West Urban Renewal Corridor between Cherrybrook and Tallawong.

We did investigations in early 2024 to help plan our work. We started construction in April 2026 and expect our work to be complete by late December. The new pipe will closely follow the existing pipe that runs through Smalls Creek between Marella Avenue and Maeve Avenue. We'll also create temporary access tracks to our work area from Bernie Mullane Complex.

Benefits

The new pipe will help support the growing community in the Metro North West Urban Renewal Corridor. This area is expected to have 24,000 new homes between Cherrybrook and Tallawong by 2026.

Impacts

  • Tree removal
    We need to clear vegetation around our work area and along the access tracks. This includes trees, weeds and ground cover. When construction is finished, we'll restore the area and replant native trees and plants. We'll follow Sydney Water Biodiversity Offset Guidelines, which include replacing any native vegetation that is impacted at a 3:1 ratio.
  • Noise
    You may hear some very loud noise when we use chainsaws, woodchippers and rock-breaking machines. The noise level will depend on how close you are to the work and the type of home you live in. We'll keep noise to a minimum, avoid unnecessary loud noises and follow all measures in the construction environmental management plan.
  • Vibration
    Some equipment may cause vibration. We'll follow all measures in the construction environmental management plan to manage vibration impacts.
  • Truck movements
    We will continue to have frequent vehicle movements in and out of the site from Marella Avenue, via local streets. Pedestrian detours
  • Pedestrian detours
    We’ll continue to temporarily close the footpath between Smalls Creek and our compound at Bernie Mullane Sports Complex. This is to ensure the safety of the community as we work nearby. There is a pedestrian detour around our site compound while this closure is in place. When moving equipment to our key work area near Maeve Avenue, we may need to close the footbridge at times. We will have traffic controllers and additional signage in place to help keep the community moving safely around our work areas. 
  • Traffic management
    There will be frequent vehicle movements in and out of the site from Marella Avenue during our standard working hours. Truck movements will vary each day. When needed, traffic controllers will help keep traffic moving safely and reduce disruption.
  • Extended work hours
    We have encountered some unforeseen technical difficulties with our tunnelling equipment. To ensure we complete our work on time, we’ll work extended hours on weekdays and begin working Saturdays, from 6 am to 6 pm. We won’t do very noisy work before 8 am or after 5 pm. For further information
  • Out of hours visits may be required
    Now that tunnelling is underway, we may need to access the site outside these work hours during heavy rainfall to pump out excess water and protect our equipment. 
    We’ll use a small generator to do this, and we don’t expect the noise to be very noticeable. We’ll ensure any lights are pointed away from our neighbours. As this is weather dependent, these visits may occur outside of our standard work hours, including night time and weekends.

At times, we may need to deliver large equipment outside standard work hours to reduce impacts on daytime traffic flows. We'll write to the local community before any out of hours deliveries.

Our work hours are 7am–6pm Monday to Friday and 8am–1pm on Saturdays. No work is planned for Sundays or public holidays. 


Project timeline

February 2024: Site investigations
We've conducted investigations to confirm ground conditions and the location of our pipes and other services to help save time during construction.
February 2026: Site compound preparation work
We'll remove trees to prepare our access tracks and set up a site compound next to Bernie Mullane Sports Complex. This area will be used to store our equipment and materials.
April 2026: Construction starts
We'll set up our work areas and install the pipe within Smalls Creek.
Late 2026: Construction finished
We'll pack up our work areas and compounds. After our work is finished, we'll restore our work areas and replant native vegetation within Smalls Creek in consultation with The Hills Shire Council.
