Storm Drainage Engineering

Roof and building storm drainage design that manages rainfall, protects interiors, and coordinates with architectural and structural systems.

What this service covers

Florida rainfall demands reliable storm drainage design. We engineer primary and secondary roof drainage, storm piping, and building drainage coordination so commercial and institutional projects manage water effectively during intense weather events.

Frequently asked questions

Direct answers for project stakeholders evaluating plumbing engineering requirements.

What is storm drainage engineering for buildings?

Building storm drainage engineering designs systems that collect and convey rainwater from roofs and related building surfaces through drains and piping to approved discharge points.

Why do commercial buildings need secondary storm drainage?

Secondary or emergency drainage provides a backup path if primary drains are blocked, helping reduce the risk of ponding, structural overload, or interior water damage during heavy rainfall.

How does Florida weather affect storm drainage design?

Brevard County and broader Florida rainfall intensities require careful drain sizing, overflow planning, and coordination with roof construction to perform during tropical and seasonal storms.

Is storm drainage the same as site stormwater management?

Building storm drainage focuses on roof and building conveyance systems. Site stormwater management addresses grading, retention, and outdoor infrastructure—often coordinated but engineered as related scopes.
