Regardless of our position in an organization or profession, we all have obligations and responsibilities to the career that we have chosen.

Plumbing systems engineering and design are better with group collaboration. I was in the U.S. Navy, and the Seabee’s motto is, “Construimus, Batuimus,” which means “We Build, We Fight.” We are trained to fight and defend what we build.

As an engineering manager, I have a responsibility to maintain a high level of quality in our “product.” But it’s my opinion that consulting engineers don’t really have a product. You might counter with — drawings and specifications are our product, are they not? Yes and no. Allow me to explain.

Mechanical engineering is an integral part of both HVACR (Heating, Ventilating, Air-Conditioning and Refrigeration) and plumbing. While both disciplines utilize the same science and engineering principles, their application diverges depending on the system under consideration. A prime example of this is the “wet” piping system that moves water through the piping network.

If you follow me on LinkedIn, you know I am passionate about advocating for plumbing engineers and designers. I have regularly written about the need for plumbing engineers, especially in solving our various water crises and improving our medical gas systems. The lesson is clear: plumbing systems are continually increasing in complexity.

Codes and standards are intended to provide a minimum level of protection for the public’s health, safety and welfare. And, generally, these documents accomplish that intended purpose in the urban/metropolitan areas of the United States. However, that may not be accurate when one gets into the rural or more isolated areas of the country.

Many of the topics I have discussed in my column to this point have been about temperature considerations within the supply and return system based on recommendations in the community and right-sizing domestic water piping to reduce the overall volume of water in the building’s piping system.

Almost 80% of all water consumption comes from two groups: No. 1, thermoelectric power, and No. 2, irrigation (farming). Public supply, which includes industrial buildings, commercial buildings and residences, accounts for only 10%.

“Governmental members” may desire a public perception of having “no vested financial interest in” the development process. But there is no requirement or mandate for them to be transparent in avoiding conflicts of interest.

There is a battle going on in the industry when it comes to domestic water distribution systems, and it lies in how plumbing engineers size domestic water piping. System longevity, pressure drop, water age, noise and building codes will influence the approach taken in sizing a domestic water system.
