About the Project
The City of St. Thomas is located near the City of London in southwestern Ontario, surrounded by farmland and close to Lake Erie. The City currently owns and operates one Lystek THP LY10 Module at its existing WRF (full project details under St. Thomas, ON WRF-I below) but the community is experiencing substantial industrial and residential growth. The new Dalewood Water Reclamation Facility is being developed to accommodate current and future growth in the region and enhance environmental sustainability and resource recovery.
Under a Progressive Design-Build framework North America Construction (1993) Ltd. engaged Lystek to complete the solids handling process design in collaboration with Project Team Designers, WSP Canada Inc., and J.L. Richards & Associates Limited throughout the Project’s initial design phases and now through final design and construction. The Dalewood WRF represents a significant milestone in municipal project delivery as the first major Progressive Design-Build project in the Ontario, Canada water and wastewater sector.
The current phase of the Nutrient Recovery Facility includes Lystek’s supply of two LY10 Lystek THP® Process Trains and associated LysteMize® Digestion, biogas utilization, dewatering infrastructure, and LysteGro® Fertilizer management. Facility construction includes footprint for a third Lystek THP Reactor, with long-term design considerations for up to six Reactors.
The Dalewood Nutrient Recovery Facility includes Lystek’s innovative LysteMize anaerobic digestion process which will generate renewable biogas to enhance resource recovery and reduce energy expenses and the carbon footprint of the facility. Alongside the City’s existing WRF, the Dalewood WRF will produce LysteGro, a Canadian Food Inspection Agency regulated fertilizer, that will be managed and sold locally to return fertilizer revenues to the City to offset program costs.
