The Jardine Water Purification Plant, formerly the Central District Filtration Plant, is the largest capacity water filtration plant in the world, located at 1000 E. Ohio Street north of Navy Pier in Chicago, Illinois. It draws raw water from two of the city's water cribs far offshore in Lake Michigan and sends nearly one billion gallons (4 million m³) of water per day to consumers in the north and central portions of the city. Constructed in the 1960s, it began functioning in 1968. Shortly thereafter the Ohio Street Beach formed in the bay created by the plant.
