The 7th Emerging Water Technology Symposium (EWTS) was held in San Antonio the second week of May. The Symposium is sponsored by the leading plumbing groups: IAPMO, ASPE, PMI, World Plumbing Council, and the Alliance for Water Efficiency. This two day Symposium always has some interesting presentations.
With the emphasis on water and water efficiency, there were presentations on water pipe sizing. Gary Klein spoke on the use of the IAPMO Water Demand Calculator. This was followed up by Prof. Steve Buchberger addressing the further evolution of the calculator. This included an evaluation of sizing water piping for large arenas and stadiums.
