Hamton
Hamton is an award-winning, innovative property developer based in Melbourne. The company employs 20 professional staff and oversees $500m worth of current development projects. Hamton’s philosophy is to ensure its developments outperform in terms of economic viability, good location, design creativity, environmental sustainability, and cultural and community outcomes.
Challenge
Hamton focuses on quality locations in the inner and middle ring suburbs of Melbourne. Here there are many former industrial sites, some needing remediation to enable their conversion to prime, environmentally sustainable residential development sites. One such site attracted Hamton, where the challenge was to remove chlorinated compounds from contaminated ground water and soil vapour, and to satisfy stringent EPA guidelines for short term remediation, as well as long term maintenance in a residential setting.
Solution
The Remediation Group designed a hydraulic containment and chlorinated groundwater treatment system that would:
- Extract the contaminated groundwater at a rate approved by the EPA.
- Ensure the water discharge complied with the Trade Waste Agreement from City West Water.
- Ensure that the vapour discharge complied with limits specified by the EPA.
- Operate while siteworks and residential construction were underway.
- Be able to be reinstalled in a dedicated room after completion of construction
- Operate quietly within the residential building development when completed.
- Operate on site for as long as needed, reliably and with low maintenance.
- Meet maintenance, energy consumption, budget and other requirements of the Owners Corporation.
- Meet Hamton’s budget and other requirements.
Results
The system was approved and, allowing for site access, was constructed on time and on budget. It has been operating for six months and:
- The water discharge from the system satisfies the requirements of City West Water.
- The vapour discharge satisfies the requirements of the EPA.
- All residential units have been pre-sold.
- Construction is expected to commence early in 2008.
Feedback
"This development would not have proceeded without the long term solution negotiated at length with the EPA. The hydraulic containment system designed and constructed by the Remediation Group is the key practical part of solution which must meet tough environmental standards for many years. We are very pleased with progress so far and with the work The Remediation Group has done. They think, they are great to work with, easy to get on with, they’re innovative and they do things on time."
