Engineered Drainage Solutions for Farms, Businesses & Developments
What Is a Retention Pond — and Why It Matters
A retention pond (or containment basin) is a vital part of modern land development and site management. It’s designed to collect and hold rainwater, runoff, or waste fluids, releasing it slowly to protect:
- Surrounding fields and landscapes
- Buildings and foundations
- Roadways, parking lots, and sidewalks
- Local waterways and wetlands
Whether you’re farming, building, or expanding — you need smart water control, and that starts with a properly constructed retention pond.

- Farms & dairies (manure runoff, containment basins)
