Eddystone Lighthouse is located in the English Channel, 14 miles south of Plymouth, England. The reef upon which it stands was the source of many shipwrecks... and many lighthouses, the first of which was built in 1698. The first three lighthouses were wooden, and suffered the fate of sea storms. John Smeaton  built the fourth lighthouse in 1759 of Cornish granite.

Chain of Rocks Water Purification Plant
Society: ASCE Main Category: Civil Sub Category: Water Supply & Control Era: 1900-1909 DateCreated: 1903 Mississippi River St. Louis State: MO Zip: Country: USA Website: http://www.asce.org/Project/Chain-of-Rocks-Water-Purification-Plant/ Creator:

Clarifying the turbid waters of the Mississippi River for use as drinking water was a formidable challenge. The Chain of Rocks Water Purification Plant provided the first application of a system of flocculation, sedimentation, and rapid sand filtration for water purification.

The system played a major role in reducing the impact of St. Louis' typhoid and cholera epidemic of 1903 that claimed 287 lives. Continued improvements to the plant reduced that number to 91 by 1914. It is estimated that 1,900 lives were likely saved between 1903 and 1915 due to the filtration system.
