Recently, the question was asked on ASPE’s Open Forum “Foundation drain pipe — plumbing responsible? Or only between civil and structural?” As originally posted, the designer did not have a Geotech report. But the structural consultant did show the piping around the top of the elevator footing and the perimeter footing for the foundation in their details.

It hasn’t taken long for some of the most obvious unintended consequences to appear: More people are complaining that their shower experience is deteriorating due to lower flow rates, and shower times are increasing as people have to shower longer to wash the shampoo out of their hair.

There has been a lot of discussion and new guidance documentation about Legionella in building water systems and the implementation of water management programs (WMP) for ongoing operations. This has led to discussions about plumbing engineering best practices to allow the building water distribution system (BWDS) to operate efficiently and safely when the building is occupied.

In creating Hunter’s Curve, the beauty of what Dr. Roy Hunter did was to take an incredibly complex problem in probability theory and make it simple — so simple, in fact, that all it required was basic arithmetic.

Regulations have been a big topic over the past several years. Politicians, trying to make a public name, have been pushing for the reduction of regulations. They like to claim that these regulations are an impediment to economic growth and entry into certain professions. While some of this may have merit, one needs to “not throw out the baby with the bath water.”  

Here are four facts about Legionella and why we as plumbing engineers should care.

After four grueling years at the Virginia Military Institute, upon graduation as an engineer, I decided to follow my own prudent path: I would find the best paying job in an area with the lowest cost of living that afforded me training opportunities. I knew myself well enough that I didn’t want to be stuck behind a desk; I desired interpersonal contact. I always aspired to be an engineering leader — and felt consulting would be the best route to that end.

Let us get down in the dirt, or at least “backfill.” A recent discussion on ASPE Connect’s “Open Forum” was entitled “Minimum Pipe Cover when Calculating Invert Under Building Slab for PVC Sanitary.”

“It couldn’t happen where I live.” Many in the United States probably thought that when watching the horror occurring in Flint, Michigan, from 2014 to 2016.

I first encountered formic acid erosion/corrosion when our installed air conditioning and heat pump evaporator (indoor) coils began suddenly leaking refrigerant in 2008. These were not old coils either, and some had only been installed for a year when the issues arose.
