Societies have had to find methods to dispose of their waste for countless years. In recent times, local governments have allocated land that has been set aside to resolve this problem. In doing this there is now a highly concentrated volume of waste that is largely uncontained.

Testing of the waterways near the waste facilities highlighted that the toxins at the waste disposal centres are being transported into the surrounding environment by the formation of contaminated water known as leachate.

Local councils have been made aware of these problems by the Environmental Protection Agency and tasked to develop solutions to reduce the amount of toxic runoff released from the site.

The Lismore City Council’s solution to this was to build a Leachate processing dam to collect, treat and release leachate in a state that would significantly reduce the harm done to the nearby waterways.

This will involve the design and construction on a dam onsite that will capture the leachate and withhold it until it is at predetermined levels that are considered safe to be in the surrounding environment.

One specific element of the dam’s design is its waterproof lining system. It is this design feature that this report will focus on and give recommendations after thorough analysis.

This project was undertaken at a time when it was expected that the results would be able to be included in the report. Due to the covid situation that is not the case and as of the submission of this report, the final designs for the dam and the construction timeline have still not been submitted to council.
