“As engineers, we were going to be in a position to change the world — not just study it.” — Henry Petroski
2024 has officially started, and most of us have an idea of some initial goals for the beginning of the year. For 2024, right-sizing the water supply looks to continue to be a central topic. IAPMO created the Water Demand Calculator Task Force in 2011, and working in conjunction with the University of Cincinnati (UC) and the American Society of Plumbing Engineers (ASPE), created a new peak flow calculator for single- and multi-family residential applications. This update, which was released in the 2018 Uniform Plumbing Code (UPC), represented the first revision of peak flow rate calculations in almost 80 years. Since then, IAPMO has continued to grow the Water Demand Calculator program and is actively working on expanding peak flow rate calculations into commercial buildings.
