Constructed wetland definition

Constructed wetland means a manmade shallow pool that creates growing conditions suitable for wetland vegetation and is designed to maximize pollutant removal.

Constructed wetland means an artificial wetland that uses natural processes involving wetland vegetation, soils, and their associated microbial assemblages to treat domestic wastewater, industrial wastewater, greywater or stormwater runoff, to improve water quality.

Constructed wetland means intentionally designed, built and operated on previously nonwetland sites for the primary purpose of wastewater treatment or stormwater retention; such wetlands are not created to provide mitigation for adverse impacts or other wetlands.

Examples of Constructed wetland in a sentence

• Constructed wetland ponds can also be designed for flood control in addition to capture and treatment of the Water Quality Control Volume.Although this BMP can provide an aesthetic onsite amenity, constructed wetland ponds designed to treat stormwater can also become large algae producers.

• Constructed wetland treatment systems shall be designed, constructed, operated and maintained as follows: 1.

• Constructed wetland is a biological wastewater treatment technology designed to mimic processes found in natural wetland ecosystems.

• Retention systems therefore may maintain a significant volume of water between runoff events.• Constructed wetland systems are similar to retention and detention systems, except that a major portion of the BMP water surface area (in pond systems) or bottom (in meadow-type systems) contains wetland vegetation.

• Constructed wetland channel preceded by modular block porous pavement.

• Constructed wetland channel, in conjunction with extended detention basin, retention pond, constructed wetlands basin, porous pavement detention, porous landscape detention, or sand filter extended detention watershed.

• Figure 2: Constructed wetland planted with Reedmace (Typha latifolia) on 23 May 2003: a) System overview showing also the aeration pipes fed by an air pump (left picture); and b) System details including the locations of the large outlet pipe and one of the four small aeration pipes (right picture).

• Constructed wetland will be monitored periodically to identify changes in wetland quality or functions.

• Porosity = 0.252’Porosity = 0.33Biotreatment volume calculation is similar to bioretention without underdrains, but applies a higher design percolation rate to account for infiltration into an amended soil layer and not underlying soils. Constructed wetland - A constructed wetland is a system consisting of a sediment forebay and one or more permanent micro- pools with aquatic vegetation covering a significant portion ofthe basin.

• Constructed wetland systems are able to remove a variety of contaminants, including algae.

More Definitions of Constructed wetland

Constructed wetland means areas intentionally designed and created to emulate the water quality improvement function of wetlands for the primary purpose of removing pollutants from stormwater.

Constructed wetland means a vegetated area that has been deliberately modified to provide or enhance habitat, to provide water quality benefits, or to moderate water flow rates or velocities, that is inundated or saturated by surface water or groundwater at a frequency and duration sufficient to support a prevalence of vegetation typically adapted for life in saturated soil conditions, commonly known as hydrophytic vegetation.

Constructed wetland means a designed and man-made system comprised of a basin containing soil at the bottom with emergent and submergent vegetation, animal life and water that simulates natural wetlands, and is used for further wastewater treatment following a sewage treatment plant or wastewater treatment lagoon;

Constructed wetland means those wetlands intentionally created from non- wetland sites for the sole purpose of wastewater or stormwater treatment.
