Natural Filtration System
A natural filtration system is another stormwater management tool. We have several options to treat residential stormwater runoff:
- Surface sand filter: We use a flow splitter to disperse the runoff into a sedimentation chamber. At this point, the sand filters the pollutants before the water seeps underground.
- Underground sand filter: This method works best when you have limited space. We place the sand filter in an underground vault, and the runoff enters via manholes and grates. The filtered runoff then seeps away into the soil.
- Vegetative filter: These filters use plant structures to facilitate the removal of sediment, nutrients, and pollutants.
- Organic filter: This filter works like a surface sand filter. The only difference is that, instead of sand, we use leaf compost or a peat-and-sand mixture to filter the stormwater runoff.
- Pocket filter: This type of filter is a less expensive variation of the sand filter, except that it uses a grass filter and a plunge pool. The filter bed consists of a shallow basin with a sand, soil, and grass filtration system. The filtered runoff then enters the plunge pool before it drains into the ground.
- Submerged gravel wetland: This filtration method comprises a set of cells with gravel (or crushed rock). The pipe leading into each cell is angled to feed the stormwater runoff into them. We also incorporate the roots of wetland plants into the system to serve as a further filter. This process helps to treat the runoff before it seeps into the soil sufficiently.
Stormwater Management Systems: Detention and Retention Basins
Fundamental Siteworks can also install detention and retention basins. A detention basin (or detention pool) is a manufactured depression in your yard that collects and stores the stormwater runoff. These detention basins are also known as wet basins as they form permanent ponds.
Alternatively, a retention basin is also a manufactured depression, but it functions differently. A retention basin collects and gradually releases the stormwater in a safe manner. This type of stormwater management structure does not hold water in a permanent pool. A retention basin is also called a dry basin (for example, a rain garden).
Our stoneworks are high-quality, artisanal pieces to help our clients make these stormwater management systems attractive backyard features.
