Plumbing Design

Water supply, drainage, and sustainable systems designed to last.

Our plumbing engineering team designs water supply, sanitary drainage, stormwater, and specialty systems for buildings of every scale. We produce construction documents that address hydraulic performance, material compatibility, code compliance, and long-term maintenance access.

Water supply designs include domestic cold and hot water distribution, recirculation systems, and booster pump sizing. We specify backflow prevention assemblies, water meters, and pressure-reducing valves to protect the building and the municipal supply.

Drainage and venting systems are designed with proper slope, cleanout placement, and fixture-unit loading to prevent blockages and siphonage. For commercial kitchens and laboratories, we design grease interceptors, acid waste neutralization, and specialized venting.
