Understanding Performance of the Swale in Phosphorus Removal from Lagoon Effluent

Rural Municipality of St. François Xavier developed a strategy to lower total phosphorus level below legal water discharge limits when over-limit phosphorus values are measured at the discharge pipe of the lagoon. This strategy consists of a trickled discharge of lagoon treated water and a swale system. Swales are widely applied to manage surface runoffs from urban areas and reduce phosphorus and other pollutants in the runoffs before they reach to the receiving water bodies. While it is a quite effective method in the management of surface runoffs, it did not work for the phosphorus removal from the lagoon treated water. The aim of this project is to find out the cause/s for the swale system failure and accordingly develop a nutrient reduction strategy by improving the current strategy
