Title

Subsurface Wetland Systems For On-Site Wastewater Treatment And Reuse

Abstract

When urban regions gradually expand due to regional development, centralized sewage collection, treatment, and disposal systems are often unavailable for both geographic and economic reasons. As a consequence, about a quarter of the residences in the United States relied on decentralized treatment of wastewater. Household wastewater contains high concentration of nutrients (mainly nitrogen and phosphorus), disease-causing organisms and viruses, and some toxic chemicals. Nation wide, wastewater effluent from on-site wastewater treatment (OWTS) can represent a large fraction of nutrient loads to groundwater aquifers. Phosphorus and nitrogen compounds are the most frequent measurements to indicate nutrient loadings. Some aquifers may discharge into springs or other surface waters adversely affecting public health. Hence, on-site wastewater effluent disposal has contributed significant adverse impacts to the dynamics of the natural environment. Nowadays, scientists, engineers, and manufacturers in the wastewater treatment industry have developed a wide range of alternative low impact development (LID) technologies designed to handle increasing impact in OWTS. This paper aims to present an innovative design of using a subsurface wetland system with unique growth media and pollution control media to grow three types of plant species that have higher uptake rate of nutrient to polish the effluents from septic tank systems. A control case was prepared for comparison. The pilot plant is up and running at University of Central Florida (UCF). © 2009 American Society of Civil Engineers.
