Storm Sewer • Detention • Drainage Repair
Stormwater & Drainage
Water is the single biggest threat to a finished site. EMC installs the pipes, structures and facilities that collect, convey, slow and release stormwater — and repairs the failed drainage that lets water go where it shouldn't.
Manage the Water, Protect the Site
A Complete Stormwater System — Collection to Outfall
Every developed site changes how rain moves across the ground. A stormwater system puts that water back under control.
EMC builds the full network: inlets and catch basins that capture runoff, storm sewer and culverts that carry it, structures that hold it, and outfalls, headwalls and riprap that release it without eroding what's downstream. On sites where drainage was never built right — or has since failed — we diagnose the problem and rebuild the flow path.
Storm work rarely stands alone, so our crews coordinate closely with grading, utilities and paving to keep elevations, tie-ins and schedule aligned.

How a Stormwater System Actually Works
Every good drainage design does four jobs in order. We build each one to work with the next.
Collect
Inlets and catch basins capture runoff from pavements, roofs and graded areas before it can pond or erode.
Convey
Storm sewer, culverts and channels carry water through the site along a controlled, engineered path.
Store
Detention and retention facilities hold peak flows so the site releases water at a controlled rate.
Release
Outfalls, headwalls and riprap discharge water safely without scouring the receiving channel.
When Water Is Already a Problem
Drainage Corrections & Emergency Repairs
Standing water, washed-out shoulders, flooded parking, undermined pavement, eroded banks — these don't fix themselves, and they get worse with every storm. EMC responds to failing and failed drainage, finds the cause and rebuilds the flow path so the problem stays fixed.
- Chronic ponding & flooding
- Collapsed or undersized pipe
- Eroded swales & channels
- Undermined pavement & shoulders
- Streambank & outfall scour
- Time-sensitive storm damage
