At a time when concern for the environment has never been more in focus, it is a great pity that in the UK, compliance with regulations means that vertical conveyors aren't specified. For sludge handling, instead of having so much site space taken up with horizontal and inclined conveyors, carbon footprint would be vastly reduced if vertical designs were permitted under Water Industry Mechanical and Electrical Specifications (WIMES). As well as the expansive space required across a treatment plant for non-vertical designs - resulting in capital and civils costs for concrete slabs and much more, there is also the need for larger motors, larger gearboxes, increased maintenance -all of which goes against the grain of totex. If the industry does truly believe in reducing its carbon footprint, then maybe the time is now for water companies, contractors and the supply chain to discuss reviewing this particular stipulation of WIMES.
