Plumbing and Piping Engineering
Protecting Patients Through Every Critical Connection
In healthcare, plumbing and piping systems go beyond moving water and gases through a building.
They support breathing, anesthesia, surgery, infection prevention, sterile processes, diagnostics, equipment operation, sanitation, and the daily delivery of patient care. Their performance—and their failure—can directly affect clinical safety and operational continuity.
For more than 60 years, Mazzetti has designed healthcare plumbing, medical gas, and specialty piping systems for new facilities, campus expansions, infrastructure renewals, and complex renovations within occupied hospitals.
Our Projects
Medical Gas Systems
Life-supporting infrastructure designed for clinical safety, reliability, and continuity of care.
Medical gas systems are essential clinical infrastructure.
Mazzetti’s engineers understand how medical gases are produced, stored, distributed, monitored, and used throughout the care environment. We coordinate closely with clinicians, facility operators, medical-equipment planners, architects, contractors, and certification teams to align each system with clinical demand and operational protocols.
Engineering for Critical Clinical Environments
Coordinated, redundant, and phased systems that support new hospitals, campus upgrades, and active patient-care renovations.
- Source + Distribution: oxygen, medical air, instrument air, vacuum, specialty gases
- Safety + Controls: alarms, zone valves, emergency shutoffs, redundancy
- Planning + Coordination: capacity assessments, campus planning, headwall coordination, testing and certification
- Renovation + Phasing: replacement strategies in active care environments
Whether designing a new hospital or replacing an aging system without interrupting care, Mazzetti approaches medical gas infrastructure with the rigor appropriate to a life-supporting system.
Water Safety is Patient Safety
Healthcare water systems require a careful balance of water quality, temperature, turnover, conservation, redundancy, and pathogen-risk management.
Mazzetti’s industry involvement has included ASHRAE Standard 188, Legionellosis: Risk Management for Building Water Systems.
A Mazzetti leader represented the American Society for Health Care Engineering during the development of the standard, helping bring healthcare-specific operational realities into the process.
ASHRAE Standard 188 addresses risk management across building-water-system design, construction, commissioning, operation, and maintenance—making early engineering decisions an important component of a healthcare organization’s broader water-management program.
Our engineers consider water safety throughout the system, including storage, distribution temperatures, recirculation, balancing, stagnation risk, fixture selection, commissioning, renovation phasing, and long-term maintainability.
