Winsor Lake Water Treatment Plant
St. John’s, Newfoundland
The Windsor Lake Water Treatment Plant supplies the majority of water for the City of St. John’s, NL, using microfiltration membranes as the main treatment process. The treatment process consists of alkalinity enhancement with hydrated lime and carbon dioxide, screening, membrane microfiltration, primary disinfection using ultraviolet light and secondary disinfection with chlorine. The backwash water generated by the facility is discharged regularly to a forebay and constructed wetland. The wetlands designed to reduce the total suspended solids concentration in the backwash water by approximately 75% before returning that water back to Winsor Lake; this process helps maintain the 99% efficiency of the plant. The facility can provide the maximum capacity of 100 million liters per day (MLD), which is the second largest membrane water treatment facility in Canada and the first utilizing this particular technology in the province of Newfoundland and Labrador.
The Johnson GEO CENTRE is a geological interpretation center located on Signal Hill in St. John’s, Newfoundland and Labrador. Unlike any other in Atlantic Canada, most part of GEO center is located underground in an excavated glacial formation that shows the exposed bedrock of the hill. Focusing on the geology of Newfoundland and Labrador, it tells the amazing story of the Earth — going back almost to the planet’s birth, over 4.6 billion years ago. As “Earth’s Geological Showcase”, Newfoundland and Labrador is one of the few easily-reached places where the geological record so fully reveals the life-story of the blue planet.
GEO houses exhibits on geoscience, oil & gas exploration, natural resources, space exploration & the Titanic. The ExxonMobil Oil & Gas Gallery tells the story of exploration of the Newfoundland offshore, and features interactive stations and large scale models of the Hibernia oil platform and FPSO (floating production, storage and offloading) vessels. The Titanic Story tells the tragic tale behind one of the most memorable nautical disasters in history, and features artifacts from the Titanic and her sister ships, as well as items from James Cameron’s Titanic movie.
