By capturing and retaining stormwater runoff, wet retention ponds control stormwater quantity and quality. The ponds natural processes then work to remove pollutants. Retention ponds should be surrounded by natural vegetation to improve bank stability and improve aesthetic benefits..
Besides, do I need a retention pond?
A retention pond looks like a regular pond, but plays an important role in controlling stormwater runoff. The basins are important for storing and slowing stormwater runoff from nearby areas, especially areas with asphalt or concrete development.
Beside above, what is the point of a retention pond? It also causes erosion, decreases groundwater recharge and alters aquatic environments.

Similarly, is it safe to live near a retention pond?
While there are some advantages to living near a retention pond—peace and quiet, green space, fewer neighbors nearby, and a decreased risk of flooding—potential buyers have other factors to consider. For example, there is a constant danger of drowning for families with young children.
How is a retention pond usually built?
