Case Study - Ontario Landfill Site

Detailed View

Graphic data representation over time can identify many salient issues. At this site several system problems showed up when the data was analysed:

1. The leachate pump in the top graph uses a zone switch to select different sections for draining. A faulty relay was identified and failed to close properly. This would likely have resulted in a complete failure if left alone.
2. In the bottom graph the data identified several issues with the well system, the primary problem being a faulty leachate pump. As a result of the faulty pump most of the pumping energy went into filling the outflow hose and the leachate discharged into the drain only for the last 20% of the run cycle.
