​Plumbing Engineering Services
Precision Plumbing Engineering. Built for Every Application.
Plumbing systems are among the most essential, and most complex, components of any building. When designed well, they operate invisibly, delivering clean water, managing waste, and supporting the full range of a building's functional needs without interruption. When they are not designed well, the consequences are costly. At Breen Design Group, our plumbing engineering team brings the technical depth, hands-on experience, and meticulous attention to detail that every project demands, from straightforward domestic water systems to highly specialized industrial and laboratory applications.

Full-Service Plumbing Design for Every Building Type

Our plumbing engineers are experienced across a broad range of building types and scales. We design domestic water systems for both low-rise and high-rise buildings, engineering solutions that account for pressure requirements, occupancy loads, and long-term efficiency. Our sanitary waste and vent systems are designed to meet all applicable codes while ensuring reliable, trouble-free performance throughout the life of the building.
Water conservation and sustainability are increasingly critical priorities in California and beyond. Our team designs gray water systems and stormwater collection infrastructure that help clients reduce water consumption, meet Cal Green requirements, and contribute meaningfully to their sustainability goals. We also design water softening and deionization systems for projects where water quality is a specific operational concern.

Specialized Systems for Complex and Industrial Applications

Beyond conventional building plumbing, Breen Design Group has significant expertise in highly specialized systems that demand a greater level of engineering rigor. Our capabilities include steam systems, compressed air systems, and vacuum systems design, infrastructure commonly required in healthcare, laboratory, industrial, and research environments. We engineer laboratory waste and ventilation systems, acid neutralization systems, and natural gas distribution systems, ensuring that even the most technically demanding plumbing requirements are met with precision and full code compliance.
Our team also brings specialized experience in commercial kitchen plumbing for restaurants and food service facilities — a uniquely demanding application that requires careful coordination of grease waste systems, drainage, gas lines, and ventilation to meet both health code and operational requirements.
 
Drainage Solutions That Protect Buildings and Sites
Effective roof and area drainage is a critical but often overlooked aspect of plumbing engineering. Breen Design Group designs drainage systems that efficiently manage stormwater runoff, protect building envelopes, and prevent costly water intrusion, an especially important consideration in California's varied climate conditions.
