Worked at Louisville Water since 2022
“One of the things this city’s always been proud of is its drinking water. It’s just good straight from the tap.”
David Mulloy drank Louisville Pure Tap® long before he worked for Louisville Water Company.
Mulloy couldn’t have known drinking water would turn into his career. He spent several years working with wastewater and stormwater projects at Louisville MSD.
“The difference between the work I did at MSD and the work I do here is everything here is pressure flow because I mostly deal with it (water) once it leaves the plant; transmission and distribution,” Mulloy explained.
Starting as a project engineer at Louisville Water, he quickly moved up to the role of manager of infrastructure planning. Timing is everything.
“The afternoon before I was to get on a flight to Hawaii for my honeymoon, I got a call.”
Mulloy’s coworker told him he was taking his name out of the ring for the manager’s job and wished him luck.
“So, then I had to do interview prep on my honeymoon,” Mulloy chuckled. “My wife was very understanding. I did promise her a return trip to Hawaii. I still owe her that. I think we’ll go probably in the next year or so.”

And the studying paid off because Mulloy landed the promotion. His passion for engineering is obvious, and it’s a job that he doesn’t take lightly.
Mulloy said, “What I need to do in my position is make sure that we are choosing the right investments to make in our infrastructure, the right timing to either build new or replace, and that we do it in such a way that those will last another 100, 150 years.”
Mulloy credits engineers who came before him who had the same forward thinking and careful planning. He points to the Oak Street Project as a good example of a pipe that’s served our community well.
“The reason that that main lasted us 130 years is because it was well-built, it was well-designed, it was installed properly, well-constructed. As we’re replacing that with this 48-inch ductile iron main, we need to make sure that that’s replaced properly, constructed properly. We are going to expect that to last us another 100 or so years.”
Mulloy realizes these projects can create inconveniences but says they’re necessary and that’s why it’s important to get it right the first time.

“I take a lot of pride in knowing that I’m one of the people that’s responsible for producing such a quality product. It’s a big responsibility to know that a million people depend on your work every day, but I really enjoy it.”
More than four years since taking the plunge on something new, Mulloy has no regrets.
“I thought it would be a really good fit, and it turns out, it has been.”
