Plumbing Engineering

WFT Engineering provides comprehensive plumbing engineering design for commercial, institutional, and recreational buildings throughout the Maryland and DC area. Our licensed plumbing engineers deliver code-compliant, efficient, and resilient systems that support health, safety, sustainability, and long-term building performance.

Our Plumbing Engineering Services

Water & Waste Systems

Venting, Gray Water & Acid Waste

  • Complete water distribution, sanitary waste, and venting systems that meet all local code requirements and ensure safe, reliable operation throughout the building.
  • Gray water systems capture lightly used water from sinks, showers, or laundry and repurpose it for non-potable uses, helping facilities improve sustainability and reduce utility demand.
  • Utilize acid waste piping and neutralization systems for laboratories and industrial facilities that generate corrosive process waste and require specialized handling.

Stormwater Management

Drainage & Rainwater Harvesting

  • Engineered systems that capture, control, and convey stormwater to protect structures, reduce runoff, and support environmental compliance.
  • We engineer rainwater harvesting systems that collect, filter, and store roof or site runoff for reuse in irrigation, flushing, cooling towers, and other approved applications.

Specialized Water Treatment

Water Reclamation & Reuse, Reverse Osmosis (RO), De-ionized Water

  • Advanced filtration and purification infrastructure.
  • Our reverse osmosis systems create purified water for laboratories, medical facilities, food service, and other applications requiring high water purity.
  • We provide de-ionized (DI) water system design for facilities that need mineral-free, ultra-pure water.
  • Our complete pure water system engineering combines multi-stage filtration and treatment to meet strict quality requirements found in labs, pharmaceutical, and clean-process environments.

Fuel & Gas Distribution

Gas Piping, Fuel & Natural Gas Systems, Medical Gas Systems, Vacuum Systems

  • Safe, efficient design for natural gas and fuel piping systems supporting a range of commercial, industrial, and specialized facility needs.
  • WFT Engineering assists in fuel and natural gas system design for boilers, generators, and specialized equipment.
  • We design code-compliant medical gas systems for healthcare facilities, including oxygen, nitrous oxide, medical air, and vacuum, for critical patient care environments.
  • Services for central vacuum systems and specialty vacuum solutions for laboratories, healthcare facilities, and industrial applications that require precise, safe suction control.

Heating & Hot Water Systems

Domestic Water Heating Systems

  • Our team designs domestic hot water systems sized for the building’s demand, 
  • Systems include high-performance water heaters, boilers, recirculation loops, and efficiency-focused distribution strategies.

Frequently Asked Questions

A plumbing engineer designs the water supply, drainage, gas, and specialty piping systems that support safe, efficient building operation while ensuring full code compliance.

Yes! Our staff provide plumbing engineering design, upgrades, retrofits, and system evaluations for both new construction and existing facilities.

Medical gas systems are required in healthcare environments such as hospitals, clinics, dental offices, surgery centers, and laboratories where patient care or specialized processes depend on clean, regulated gases.

Water reclamation systems help building owners reduce potable water use, lower utility costs, and meet sustainability goals by reusing treated gray water for approved non-potable applications.

Rainwater harvesting is ideal for buildings with large roof areas, sustainability certifications, or high irrigation or non-potable water demands. This provides both environmental and cost-saving benefits.

Laboratories, pharmaceuticals, research facilities, electronics manufacturing, and medical environments often require purified water systems to support sensitive equipment and processes.
