Perhaps its just me, but I had no idea these existed away from the science labs. So it was to my amazement that our UK team have just finished working on the design, procurement and management of a new installation in England. The screw is being used in a pump station at an environmentally protected site, which needs to maintain water levels within +/-150mm of the ground level. The project constraints meant that a traditional submerged pump would not be suitable, and instead

After taking the long journey from its workshop in Leeds, our demonstration hydraulic flume has arrived in Queensland. We recently performed an afternoon of demonstrations in our office in Spring Hill, using the tank to show the principles of open channel flow. What more could you want on a Friday? The mini flume is a scale model of a river or stormwater channel, driven by a system of recirculating pumps and featuring typical engineered structures such as weirs, bridges, cu
