You would expect water in a hospital to be safe. But, far too often, water in hospitals and other health care facilities can put patients at risk of severe illness or death.

Fresh water is an undeniably valuable and essential natural resource. But are plumbing engineers unintentionally putting building occupants are risk by implementing water conservation guidelines and equipment? What are the unseen consequences of water conservation?

When I first entered the trades in 1972, residential tank-style water heaters shipped with the aquastat set to approximately 140° F. Dishwashers had no need to incorporate a sanitizing cycle. Around 1977, water heater manufacturers were required to lower the aquastat temperature setting to approximately 120°, and now, dishwashers needed to incorporate a sanitizing cycle where rinse water in their reservoir was raised to 140° or higher.

By completing all eight modules, engineers can receive 0.25 Continuing Education Units (CEUs) through the American Society of Plumbing Engineers (ASPE), and all participants who complete the modules will receive a Certificate of Completion for the course

The two-day special session, hosted by NSF Health Sciences, an NSF International company, and the National Environmental Health Association (NEHA), will also address how industries such as health care, water utilities, manufacturing and hospitality, as well as health departments and regulators, can better respond to water-related challenges during a major health crisis.

Anyone can become ASSE-12080 certified by completing 24 hours of approved education and then passing the ASSE-proctored exam.

In 1976, while attending an American Legion Convention at the Bellevue Stratford Hotel, 211 people became ill and 34 of them died from what was thought to be a previously unknown type of bacterial pneumonia. 

When it comes to emerging technologies — both hardware, and digital technologies — it’s likely that backflow isn’t the first thing to come to your mind. 

It’s a sign that a topic is going mainstream when it becomes cited in the model codes.
