Answers to common questions about Walleys Quarry

What is leachate and how is it managed?

As rainwater drains through the waste in the landfill, it dissolves a range of substances which then collect at the base of the landfill as a polluted liquid. This is known as leachate and it can contain high levels of contaminants, including ammonia.

The operator has a leachate treatment plant at the facility. Following treatment leachate is removed from site.
