Description

Municipalities in the Intermountain West are facing water shortages according to the current population growth projection. Among others, Mount Pleasant, UT, is a city that is seeking innovative and cost-effective ways to reduce culinary water use. This study presents a feasibility analysis and a design of using a free water surface constructed wetland system to treat the city’s wastewater. The study further assesses the cost-benefit of using the treated water for landscape irrigation in the surrounding areas. The study involves retrofitting the existing wastewater sewage lagoon, the design of a constructive wetland and a storage pond for reclaimed water. Design of the constructed wetland also takes into account various recreational and educational opportunities as envisioned in the city’s general plan. The design is based upon existing wastewater quality, local climatic and site biophysical conditions, and future water use projections. For municipalities that are concerned with similar challenges, this study provides an example of reducing culinary water use and achieving other sustainable development goals.
