The new standard will reference ASHRAE 188 for control of the Legionella bacteria.

To ensure the health and safety of building occupants, proper design, installation and operation of a potable water system are paramount. Plumbing designers can play an important role in this process.

The ramifications of the Flint, Mich., water crisis continues to spread more than two years after the city was thrust into the national spotlight because of lead contamination in its drinking water. What happened in Flint was a tragedy but it also accelerated a larger trend around municipal water.

Scalding hot water from fixture faucets and fittings accounts for more than 25 percent of all scald burns in children. The elderly and the physically impaired also are at increased risk of scald burns because they have thinner skin and slower reactions. They often cannot recognize a hazard and get out of harm’s way before a serious burn can occur. 

We now know that storing water at 110 F, as was called for in many energy conservation mandates in the 1970s, can lead to an increase in Legionella bacteria growth in the hot water storage and distribution systems, which could eventually lead to outbreaks.

The new product helps protect against legionella growth in domestic hot water systems.

We have learned much about controlling the growth and spread of Legionella bacteria in water systems. Health-care facilities are especially vulnerable. ASHRAE-compliant water management programs can reduce the risk for Legionella and other pathogens in their water systems.
