The Jardine Water Purification Plant, formerly the Central District Filtration Plant, is the world’s largest water filtration plant, purifying 1.4 billion gallons per day. It is located at 1000 East Ohio Street, north of Navy Pier in Chicago, Illinois. The plant draws raw water from two of the city's water cribs far offshore in Lake Michigan and supplies two thirds of City of Chicago consumers in the northern, downtown, and western parts of the city and to many northern and western surrounding suburbs.
