Examples of Constructed wetland in a sentence

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

  • 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.

  • 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).

  • 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 systems are engineered systems which use vegetation, soils and microbial activity for the purposes of treatment wastewater and/or post-treating wastewater effluent.

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

  • Constructed wetland ponds are allowed provided adequate documentation is submitted to establish the presence of a sufficient and sustained flow of water to support the proposed vegetation in the planned constructed wetlands.

  • Constructed wetland systems for wastewater treatment have been in operation in Denmark since early 1980s.

  • Constructed wetland ponds can also be designed for flood control in addition to capture and treatment of the Water Quality Control Volume.


More Definitions of Constructed wetland

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.
Sample 1
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;
Sample 1Sample 2
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.
Sample 1Sample 2
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.
