<P> The water cribs in Chicago are structures built to house and protect offshore water intakes used to supply the City of Chicago with drinking water from Lake Michigan . Water is collected and transported through tunnels located close to 200 feet beneath the lake , varying in shape from circular to oval , and ranging in diameter from 10 to 20 feet . The tunnels lead from the cribs to one of two water purification plants located onshore , the Jardine Water Purification Plant ( the world 's largest ) and the Eugene Sawyer Water Purification Plant , where the water is then treated before being pumped to all parts of the city as well as 118 suburbs . </P>
