Talis has been working with Bunbury-Harvey Regional Council to deliver integrated hydrogeological and geotechnical engineering solutions to the Stanley Road Waste Management Facility.
The facility is situated to the 20 km north of Bunbury in WA. The facility commenced operations in 1991, accepts Class II/III putrescible waste and was constructed as an unlined facility. Underlying soil conditions were considered to be highly permeable in nature with two shallow aquifers known to exist beneath the facility. The Council engaged Talis to undertake an assessment of the potential impacts the facility may be having on the groundwater resource within the area. Through our continuing relationship, Talis was also engaged to undertake the engineering assessment of subsoils for the expansion of the facility’s capacity to ensure the continued operation of the facility as a necessary service to the wider community.
The successful delivery of this project resulted in Talis undertaking a wide range of investigations, including:
- Initial desktop hydrogeological risk assessment;
- Liaison with the Department of Environment Regulation (DER);
- Intrusive hydrogeological investigation including aquifer property testing;
- Intrusive geotechnical investigation in relation to the expansion of the waste management facility.
- Seasonal groundwater monitoring;
- Hydrogeological modelling utilising LandSim;
- Hydrogeological risk assessment;
- Detailed geotechnical assessment of the engineering properties of the underlying soils;
- Slope Stability assessment; and
- Ongoing advisory services for both hydrogeological and engineering constraints to the facility.
Through our work, Talis was able to establish the potential risks associated with the operation of the facility to the surrounding environment and associated receptors and provide management measures to ensure ongoing operations cause no unacceptable impacts.
The geotechnical assessment allowed for the classification and assessment of the suitability of the site for the proposed development expansion in keeping with the recommended framework for environmental management onsite.
