Sometime opportunities just appear and you have to make the most of them. Recently, our good friend Stephen Turfrey invited us out to watch a bioretention basin being cleaned out (thanks mate!). The system had been filled with a large amount of sediment (that washed off the yards of houses being built in its catchment). Cleaning sediment out of a bioretention system might sound easy, but there are a few key things that you have to get right. This contactor was doing a good job!
