Water Crib
Water cribs are offshore structures that collect water from close to the bottom of a lake to supply a pumping station onshore. The name crib is derived from the function of the structure—to surround and protect the intake shaft. Cities supplied with drinking water collected by water cribs include Chicago, where two of the nine originally built cribs are in active use. Water cribs were also used as residences for caretakers who would live in the structure year round. Jobs included clearing debris and maintaining valves, gears, and instruments to keep the water flowing. These jobs have since been automated with periodic maintenance leaving no need for a full-time caretaker.

Lake Erie
Lake Erie ( "eerie") is the fourth largest lake by surface area of the five Great Lakes in North America and the eleventh-largest globally. It is the southernmost, shallowest, and smallest by volume of the Great Lakes and therefore also has the shortest average water residence time. At its deepest point Lake Erie is deep. Situated on the International Boundary between Canada and the United States, Lake Erie's northern shore is the Canadian province of Ontario, specifically the Ontario Peninsula, with the U.S. states of Michigan, Ohio, Pennsylvania, and New York on its western, southern, and eastern shores. These jurisdictions divide the surface area of the lake with water boundaries. The largest city on the lake is Cleveland, anchoring the third largest U.S. metro area in the Great Lakes region, after Greater Chicago and Metro Detroit. Other major cities along the lake shore include Buffalo, New York; Erie, Pennsylvania; and Toledo, Ohio. Situated below Lake Huron, Erie's p ...

Water Cribs In Chicago
The water cribs in Chicago are structures built to house and protect offshore water intakes used to supply the Chicago, City of Chicago with drinking water from Lake Michigan. Water is collected and transported through tunnels located close to beneath the lake, varying in shape from circular to oval, and ranging in diameter from . The tunnels lead from the water cribs to Pumping Stations located onshore, then to water purification plants Jardine Water Purification Plant (the world's largest) and the Sawyer Water Purification Plant (operating since 1947), where the water is then treated before being pumped to all parts of the city as well as 118 suburbs. The city has had nine permanent cribs of which six are still standing and two are in active use. Current and former water cribs Two-Mile Crib The Two-Mile Crib was constructed as part of a scheme by Ellis S. Chesbrough in 1865, to help with the purification of the water because of damage caused by the city dumping sewage int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Michigan
Lake Michigan is one of the five Great Lakes of North America. It is the second-largest of the Great Lakes by volume () and the third-largest by surface area (), after Lake Superior and Lake Huron. To the east, its basin is conjoined with that of Lake Huron through the wide, deep, Straits of Mackinac, giving it the same surface elevation as its easterly counterpart; the two are technically a single lake. Lake Michigan is the world's largest lake by area in one country. Located in the United States, it is shared, from west to east, by the states of Wisconsin, Illinois, Indiana, and Michigan. Ports along its shores include Milwaukee and the City of Green Bay in Wisconsin; Chicago in Illinois; Gary in Indiana; and Muskegon in Michigan. Green Bay is a large bay in its northwest, and Grand Traverse Bay is in the northeast. The word "Michigan" is believed to come from the Ojibwe word (''michi-gami'' or ''mishigami'') meaning "great water". History Some of most studied ea ...

Lighthouse
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crib Lighthouse
A Crib lighthouse is a type of lighthouse whose structure rests on a concrete or masonry foundation supported with wooden beams. The name "crib" refers to the wooden crib pier style of construction which was used as a foundation for lighthouses. When it came time to build, wooden cribs were constructed onshore then towed to the site where they were filled with stone so they sank in place. The crib was then leveled and capped with concrete or masonry on which the lighthouse structure was constructed. Crib lighthouses were built extensively in the Great Lakes region, as the hardrock bottoms of these water bodies provided ideal foundations. Problems arose however if the crib settled unevenly into the earth as was the case with the Detroit River Light. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
