Proven Expertise for Stormwater Management

Drainage Strategy and Cost Control

Drainage constraints can change what a site can support and how much a project will cost. Inside a multidisciplinary firm, WGI’s specialized stormwater management expertise gives owners practical direction before drainage problems become expensive.

DIGITAL INSIGHT FOR STORMWATER MANAGEMENT

The Modeling Engine Behind Our Stormwater Work

Streamline Technologies, a WGI subsidiary, develops StormWise, the hydrologic and hydraulic engine engineers and planners have modeled with for four decades. WGI's stormwater teams run it daily and sit alongside the people who write it, so questions get answered at the source.

Answers at the Source

WGI modelers reach the StormWise development team directly when a project raises an unusual question.

1D, 2D, and Real Time

StormWise models 1D and 2D flow, and FloodWise forecasts flooding days ahead at the street and house level.

Stormwater Requirements That Shape Site Feasibility

A site can look promising until runoff control, detention space, or outfall constraints change the development picture. Specialized stormwater management helps owners see how much usable land remains and what the site can realistically support.

Evaluate detention and treatment needs that influence usable land and site layout.
Account for grading, outfalls, and drainage patterns, which impact what the site can support.
Connect stormwater requirements to early decisions so owners realize project limits.
