Storm water doesn’t wait—it flows fast, erodes pavement, floods parking lots, and weakens foundations. Without a proper drainage system in place, every heavy rainstorm is a risk to your property. Retention and detention ponds are engineered solutions that control water before it becomes a costly problem.








When it rains, your property shouldn’t turn into a swamp, river, or lake. Storm water needs a place to go, and without a controlled system, it will erode your pavement, flood your buildings, and overrun local drainage infrastructure.
Retention ponds are designed to hold water permanently, gradually absorbing it into the ground while filtering pollutants and preventing excessive runoff. These systems are ideal for commercial developments, industrial sites, and large paved areas where water collection and slow absorption are necessary.
Detention ponds temporarily store storm water during heavy rain, releasing it slowly to prevent overwhelming drainage systems. They are crucial for flood-prone properties, parking lots, and HOAs that need to control large amounts of water quickly and effectively.
If your property experiences standing water, frequent runoff, or pavement erosion after heavy rain, you likely need a storm water management solution. A professional assessment from Swan Co. will determine whether a retention or detention pond is the right fit for your property.
A retention pond permanently holds water, allowing gradual absorption while improving water quality by filtering out debris and pollutants. A detention pond is designed to temporarily store storm water and release it slowly, reducing the risk of flooding and controlling peak water flow.
Routine maintenance includes clearing debris, ensuring proper drainage flow, removing sediment buildup, and checking for erosion. Regular inspections ensure your system remains compliant and functional year-round.
