Consultation has concluded

This Proposal

Council is preparing a Catchment Action Plan (CAP) for the four sub-catchments of Prospect Creek. The study area is provided in the map below and is divided into four sub-catchments being:

  • Georges Hall;
  • Lansdowne;
  • Miller Road; and
  • Villawood.

The objective of the CAP is to:

  • Undertake a comprehensive assessment of the current catchment conditions including water quality, water balance, blue and green spaces and current stormwater management;
  • Identify issues and opportunities for the area and;
  • Develop management actions that provide social, environmental, and economic benefits .

The following tasks will be undertaken:

  • Comprehensive data collection and review;
  • The assessment of the catchment through catchment profiling, baseline condition and water balance assessment and water quality modelling;
  • Consultation with community and stakeholders, including public exhibition of the CAP; and
  • Development of catchment management actions that includes assessment and concept design.

In simple terms, a catchment is any area which rain falls on to and then drains to a single point. A catchment can be as small as a roof or as large as the Murray-Darling Basin. What happens in this area determines a catchments water quantity, quality and its behaviour.

Before people started changing the environment, a catchment would have been an area where water collected by the natural landscape. Its hills and mountains define this area and some rainwater would eventually flow to the lowest point, most likely, a creek, river, lake or ocean.

In the present day, the Prospect Creek Sub-catchments have become a mix of leftover natural environments mixed with urban environments (i.e. houses, business and roads). This mix of natural and urban environment is not unique. The challenge is maintaining a healthy catchment.

Healthy catchments can provide:

  • a source of clean drinking water
  • unspoilt natural areas for recreation
  • safe areas for people, plants and animals
  • healthy plants and waterways
  • reliable and clean water
  • for sustainable agriculture and industry

Natural and urban systems such as rivers, bushland, farms, dams, homes, business, plants, animals and people need to co-exist in a catchment.

Our daily activities affect the health of our catchments. The first step to protect our catchments is a better understanding of our impact on them.

Urban development has had a large and immediate impact on our catchment. The biggest change is an increase in hard surfaces (roofs, roads and pavements) and the resultant reduction in permeability.

This increase in hard surfaces directly causes greater volumes of surface water. As rain that would have normally soaked into the ground will now run off the hard surfaces faster and in greater volume.

As a consequence, flooding which was always a natural occurrence would become more frequent. To combat the flooding, stormwater pit, pipes and channels were constructed to drain additional runoff to the waterways faster.

Yet, larger flows would still flow overland as stormwater network capacity was exceeded. The downside to the earlier stormwater network designs was that the faster and greater water would erode our creeks.

Also, the stormwater network would be become very efficient at moving pollutants like litter, sediment, nutrients so forth, to our waterways which are suffering as a result.


A large proportion of the study area is developed as low density residential and includes Bass Hill and Chester Hill town centres and the Villawood industrial precinct. The undeveloped areas are large open space reserves and include The Crest, Lansdowne Reserve, Amaroo Reserve and Garrison Point Reserve.

Stormwater runoff from the Georges Hall and Lansdowne sub-catchments discharges to Prospect Creek directly, while runoff from the Villawood and Miller Road sub-catchments discharges west to Burns Creek, a tributary of Prospect Creek. Ultimately this runoff flows to the Georges River and along to Botany Bay.

Community consultation is a key component of the study process and we are now seeking feedback from residents, land owners and business operators in the study area.

This is the initial community consultation stage for this project.

How to have your say

Residents, property owners and business operators within the study area are invited to share their observations and opinions of the current catchment management for the area including water quality, water balance and stormwater management.

By completing the on-line survey, we will gain a better understand for your preferences for areas of the catchment to be enhanced, and your preferred methods to achieve these enhancements. The survey is hosted by our project partners - Stantec and, we will accepting feedback until 5pm on Wednesday 5 April 2023.

Online survey

Submissions are now closed. All feedback and comments received will be reviewed and considered.
