Point-of-use (POU) water disinfection isn't just about public health; it's also an essential engineering strategy in modern water systems, tackling waterborne diseases by ensuring safe drinking water directly at the point of consumption.
Prepared by PPI’s Building & Construction Division, PPI TN-31Differences Between Crosslinked Polyethylene (PEX) and Polybutylene (PB) Piping Systems for Potable Water Plumbing Applications discusses the advantages of modern PEX tubing and fittings as compared with PB tubing and fittings, which were last sold in the U.S. during the late 1990s.
When a plumbing engineer receives the design of a health care building — our minds gravitate to designing the system to optimize all the different considerations I mentioned above — with the fixture layout the architect has developed. But what if the layout changed? What if the amount of fixtures were reduced?
The Water Demand Calculator has been adopted in several states and cities, including California and Seattle, and is expanding peak flow rate calculations into commercial buildings. The future looks bright as version 3.0 is in the works for commercial buildings.
Starting in 2020, a team of experts from PPI member companies began a research project to investigate the potential effects of chlorine dioxide on pressure piping materials CPVC, PEX, PE-RT, PP-R, andPP-RCT.
“Should we wait for lab planning to identify the plumbing fixtures and equipment before getting involved to save time and budget?” or “Should I get involved early on during the program development?”
IWSH has been working in Lowndes County for the past few years as part of a larger initiative to improve homes’ water efficiency and sanitation system functions.
