The Richmond Water Recycling Plant (WRP) and the North Richmond Wastewater Treatment Plant (WWTP) currently service two independent systems separated by the Hawkesbury River.

Both plants and their systems will have capacity limitations in the near future as the population growth in the Richmond and Upper Hawkesbury area is projected to increase by 70% over the next 30 years.

Sydney Water is planning to upgrade its wastewater infrastructure in North Richmond and Richmond to meet the needs of Richmond’s growing population, meet current regulatory requirements and provide sufficient flexibility to meet more stringent regulatory requirements in the future.

As part of this upgrade, we will

  • upgrade the local sewers in the North Richmond Catchment
  • build a new pumping station at North Richmond and upgrade two existing pumping stations in Richmond
  • build a 6.9 km long transfer pipeline connecting the North Richmond system to the Richmond Water Recycling Plant.
  • upgrade the Richmond WRP to receive additional flows from the North Richmond Catchment and to meet future growth.

The upgrade will increase the combined plant capacity by 80% and at the same time will ensure Sydney Water meets its EPA license requirements.

    The Richmond System Wastewater upgrade team have begun draining a decommissioned water reservoir at the Richmond Wastewater Treatment Plant.

    Working with the neighbouring Richmond Golf Course, the team have successfully rehomed 25 eastern long-necked turtles into the freshwater dams around the Golf Course.

    In 2020, the University of Western Sydney's Hawkesbury’s campus began a study into the effects of not having turtles in rivers on their eco-systems.

    "The research we are conducting at the Experimental Wetland Facility on the University's Hawkesbury campus shows that without turtles in our rivers, water quality would reach toxic levels during our hot summers," Mr Spencer said.

  • Smoking Ceremony to mark start of construction

    Sydney Water and our project delivery partner BMD came together last week to participate in a traditional smoking ceremony to help mark the start of construction for the Richmond System Wastewater Upgrade works.

    The rain passed just in time for a Welcome to Country by Melissa Stubbings, Senior Dharug Woman. The Smoking Ceremony was performed by by Uncle Glenn Collis, Barkinji man and Community Elder. It is traditionally held to acknowledge the ancestors and pay respect to the land and waters of country. It welcomes, cleanses and promotes the protection and wellbeing of visitors.

    Uncle Glenn, with the help of some eager participants, also led us all in a dreamtime story about how the earth was created.

    Sydney Water’s Reconciliation Action Plan (RAP) reflects our commitment to integrate the reconciliation of Aboriginal and Torres Strait Islander peoples into our business. The smoking ceremony signals our recognition that we operate on the lands of Traditional Custodians. Our purpose to protecting waterways and the environment is consistent with the environmental stewardship the traditional owners have provided for thousands of years.

    It was fantastic to be joined by so many attendees from our delivery partner, subcontractors, as well as Sydney Water staff.


  • Start of works- Site investigations

    Share Start of works- Site investigations on Facebook Share Start of works- Site investigations on Twitter Share Start of works- Site investigations on Linkedin Email Start of works- Site investigations link

    Sydney Water and its delivery partner BMD will be carrying out site investigations in different locations in the Richmond and North Richmond areas to better understand ground conditions and to inform the design of the assets, leading to construction.

    We plan to start investigation works on Tuesday 20 June 2023 and expect to finish by late July 2023, weather permitting.

    Our work hours will be from 7 am to 6 pm Monday to Friday and from 8 am to 1 pm on Saturday. No work is planned for Sundays or public holidays.

    We know our work can be disruptive, so we’ll make every effort to reduce any impact this work may have on you. You may experience:

    • Noise: During work hours moderate noise levels may be emitted due to construction machinery. No heavy noise activities are planned.
    • Parking: Some parking may be disrupted due to construction vehicles and work zones. If we cannot access a work area, it can cause delays and prolong the work.
    • Traffic: Our machinery and trucks may take space up on the street. Traffic controllers will help traffic flow while keeping you and our team safe. Allowances will be made for emergency vehicle access during this time.


    Private property access

    We will make sure that residents continue to have access to all driveways and private properties during this time.

    If we need access to inspect a Sydney Water asset located within your property, we will notify you separately to arrange access.

    We are pleased to announce that we have partnered with BMD Constructions to deliver the Richmond System Wastewater Upgrade Project. Together we will upgrade the wastewater infrastructure to meet the needs of Richmond’s growing population, meet current regulatory requirements and provide sufficient flexibility to meet more stringent regulatory requirements in the future. Detailed construction design will commence in June 2023 with community consultation as its cornerstone. During this stage, the delivery contractor will be looking to optimise the project's design with a view to further reducing impact to the community and environment.

    Construction of this project is expected to commence in September 2023 and will take 2 years to complete.

    We're planning to improving the wastewater system in North Richmond and Richmond. This work will ensure the reliability and resilience of our services and meet the demands of a growing community in the Hawkesbury.

    We have prepared a Review of Environmental Factors (REF), guided by the Environmental Planning and Assessment Act 1979. The REF looks at all the potential benefits and environmental impacts of the project as we build it and once it's up and running. The REF needs to cover all scenarios, even though there will be opportunities to improve or even eliminate some of these impacts as we continue to fine-tune this project. It includes:

    • the background to this project,
    • proposed construction activities, including work locations, and
    • potential environmental impacts, including traffic and access.

    You can view and download the REF from the Document Library.
