Dear industry colleague,

What is the impact of waterless urinal discharge on the whole of plumbing system? It seems that unless properly maintained, the waterless urinal and related plumbing system is subject to struvite blockages that can cause serious long-term damage.

The article Waterless urinal research delves into the research conducted by Australia and New Zealand formed the Australasian Scientific Review of Reduction of Flows on Plumbing and Drainage Systems (ASFlow).

ASFlow's trials have shown added flows to main pipes servicing waterless urinals will prevent rapid build-up of Struvite, but highlighted the need for on-going maintenance of the urinal’s outlet pipe at regular intervals to control the build-up of Struvite.

This problem is shared the world over and while the introduction of water saving measures are commendable, more research must be conducted before good intentions turn into nasty drainage problems.

www.worldplumbinginfo.com is on the lookout for groundbreaking technologies or research. If you feel you might have a solution to the waterless urinal problem that could be of benefit in this area to the community at large please don't hesitate to contact us.

Editor's note: Super Mario has been honoured as a super plumber by Spain's largest professional association of plumbers. This is all well and good, but what about honouring Luigi as well, surely he has done just as much to promote plumbing as brother Mario.
