Sheila Downing
Associate / Senior Designer of Plumbing Engineering Systems


It’s fair to say Sheila Downing stands out from the crowd.

After all, she’s one of a few female licensed plumbing designers in all of Wisconsin. But it’s her LEED-accreditation, impressive knowledge of plumbing design and broad experience with a diverse array of projects that really set her apart.

Over the course of her career with Somerville, she’s masterfully handled just about every type of plumbing design project—from medical gas and compressed air systems to sustainable water usage systems and specialty waste management.

Sheila’s skills were even called upon to assist with the formidable challenge of cleaning up the Fox River, helping to design the complex plumbing systems within the barge to filter harmful sediment and hazardous materials out of the basin over a 10-mile span.

Not surprisingly, Sheila enjoys activities that set her apart from the typical as well (or at least many of her female counterparts)—she shoots trap, hunts and delights in the beauty of the great outdoors. One thing’s for sure—clients who see firsthand Sheila’s commitment to designing efficient, reliable and worry-free plumbing solutions know she’s more than someone who stands out. She’s outstanding.
