Where does the water from Bioswales go?

Where does the water from Bioswales go?

Traditionally, the water runs off the asphalt into a storm gutter or along a curb until it reaches the inlet to storm sewer drain. A bioswale replaces the traditional concrete gutter with an earthen one.

Are Bioswales sustainable?

Conversely, bioswales are cheaply and easily constructed and require very little maintenance, all while enhancing the environment and reintroducing native plant species. This is a very sustainable way to both purify water and strengthen the presence of vital plant species in their native environments.

How does a bioswale work?

Bioswales work to remove pollutants through vegetation and the soil. As the storm water runoff flows through the bioswale, the pollutants are captured and settled by the leaves and stems of the plants. The pollutants then enter the soil where they decompose or can be broken down by bacteria in healthy soil.

How much water can Bioswales hold?

The rest of the water moves down through the soil and is filtered, eventually reaching the water table and joining the groundwater supply. In this way, a single bioswale can manage more than 75,000 gallons of water each year!

Are Bioswales effective?

Bioswales may be effective in any region as they can be tailored to the specific installation location by incorporating native plants. They may be designed to convey any size storm but are most effective in dealing with frequent, small rain events.

How deep should Bioswales be?

12 inches
For starters, your bioswale needs to be at least 6 or 12 inches deep (and can be even deeper depending on water amounts.)

Where are bioswales used?

What are bioswales? Bioswales are storm water runoff conveyance sys- tems that provide an alternative to storm sewers. They can absorb low flows or carry runoff from heavy rains to storm sewer inlets or directly to sur- face waters.

Are bioswales effective?

How deep are bioswales?

Typically bioswales are Six- to 12-inches deep and 3- to 4-feet wide, however, the size of the swale will depend on individual drainage needs and landscape size. The bigger the swale is, the more water it can absorb during a heavy downpour.
