The global imperative to reduce water consumption due to climate change, population growth, prolonged drought and excessive consumption has hit a major hurdle. Governments, regulators and industry around the world have failed to realize the impact of the loss of flow on the overall plumbing system.
Dry-drains and the resultant drain line carry problems are now a major plumbing performance issue, which is showing up in many regions including the USA, Europe, China, Australasia and the Middle East. These effects of reduced flow are now being observed in drain line performance within and under buildings, in street mains and are also causing further issues at treatment works. Hence the challenge for industry is to ensure that existing and new drainage systems work as they should but with less water flow.
The solutions are varied and still being worked on. More industry dialogue and consultation between continents is urgently required.
The Dry Drains Forum was held alongside ISH Frankfurt 2009, and bought together the world’s leading researchers and industry experts.
