Fenelon Falls Water Treatment Plant Clearwell Modification Study

completed

Development of a clearwell modification plan for the Fenelon Falls Water Treatment Plant to meet the Ministery of the Environment and Climate Change’s (MOECC) recently announced revised contact time requirements for disinfection at Ontario’s water treatment plants. Under current processes, these new requirements will result in the plant falling under capacity. The City is required to provide a plan by April 2017 to modify the plant to rectify this situation. Detailed design of the identified necessary process modifications will follow on development and MOECC approval of this plan. An additional anticipated change in the MOECC Water Quality Guidelines involving the limits on disinfection by-products known as THM’s (Tri-Halo-Methanes) will require a study of the treatment process upstream of the filtration system at the plant. The THM study has been deferred in the past, but may be accelerated to coincide and be included with the clearwell modification plan, if adequate funding is available. The THM study is identified in the 2014 Capacity Assessment for Fenelon Falls. These clearwell modification plan and THM study will ensure regulatory compliance with current and anticipated MOECC Guidelines, aid in providing improved water quality to over 2,500 residents and business consumers in the community and ensure projected capacity requirements in the water system are realized.
