Application of wastewater to wetland areas has been practiced at a number of sites, in some cases for more than fifty years. In most instances, natural wetland ecosystem mechanisms remove residual phosphorus, nitrogen, and other pollutants from these waters down to low levels, accomplishing advanced wastewater treatment. The design of such facilities has not, however, been reduced to practice. A simple, tractable mathematical model is developed that permits dynamic simulation of wetland hydrology and of interactions between secondarily treated municipal wastewater and the wetland ecosystem. Spatial variations due to surface water flow are described, and material balance calculations carried out for phosphorus, nitrogen, and chloride. Hydrology model features include predictions of overland flow. Ecosystem phenomena are represented, using a one-dimensional, spatially distributed compartmental model. Compartments include soil, surface water, interstitial soil water, and various types of live biomass, standing dead and litter.
