Hope Canal
Guyana
The East Demerara Water Conservancy-Northern Relief Channel, better known locally as the Hope Canal, is one of Guyana's largest drainage projects. Construction was from 2011 to November 9, 2013, at a cost of around GYD$3.6 billion. Hope Canal was designed in response to the 2005 flooding, when a breach in the embankment resulted in floods to almost the entire East Coast of Demerara causing significant damage to agricultural and residential areas. It serves as a medium to release excess water from the EDWC directly to the Atlantic Ocean via an 8-door sluice, during periods of extended rainfall in order to prevent overtopping of conservancy embankment. The project was criticized for costing well over estimates and two years of delays.
