Ottawa's Water Quality![]() Ottawa's water system draws water from the Ottawa River, a plentiful source of clean, very soft water. The river water is treated using the most effective processes and equipment available to remove colour, suspended particles, algae, vegetation, bacteria and viruses. Our water-purification processes are continuously monitored, ensuring that high-quality water is pumped out of the plants and maintained as it travels through the distribution system. The result is water that is sparkling clear, fresh tasting and safe to drink. Each year, we perform approximately 125,000 water-quality tests in municipal, provincial, federal, private and university laboratories using the most up-to-date technologies and equipment. These tests cover a broad spectrum and provide information on the physical, inorganic, organic, microbiological and radiological characteristics of the water. The results are then analysed to confirm that quality is maintained as the water travels through the distribution system on its way to homes and workplaces in Ottawa. In addition to these processes and distribution system tests, our water quality specialists are available to respond to customer inquiries and concerns. It's our job to investigate and resolve problems quickly and efficiently. Please feel free to contact us if you have any questions. Links |
