DISCHARGE OF WASTEWATER INTO WETLANDS. PROCEEDINGS OF 1989 MID-YEAR MEETING, LANDSCAPE AND ENVIRONMENTAL DESIGN COMMITTEE, TRANSPORTATION RESEARCH BOARD, WARWICK, RHODE ISLAND, JULY 23-26, 1989

As part of the federal "no net loss of wetlands" mandate, the term "mitigation" is becoming increasingly synonomous with "replacement." Wetlands replacement requires the establishment of constructed wetlands with area and functional attributes equal to or even greater than the natural wetland. In urban areas, the highly treated municipal wastewaters produced from modern facilities may be available as a water source for mitigation wetlands. The use of treated wastewater to recreate wetland hydrology and the resulting ecological benefits of this new habitat, however, must be balanced with the ability of the wetlands to assimilate residual pollutants remaining in the wastewater. Excessive pretreatment may remove nutrients that can be valuable to wetland plant and wildlife productivity. At the same time, downstream water quality must be protected through the overall process of conventional and innovative treatment technologies. This paper explores the feasibility of creating a symbiosis between mitigation wetlands and treated wastewaters, with multiple environmental and economic benefits to society.
