The Droitwich Canal is a synthesis of two canals in Worcestershire, England; the Droitwich Barge Canal and the Droitwich Junction Canal.
 The Barge Canal is a broad canal which opened in 1771 linking Droitwich Spa to the River Severn at Hawford Mill, Claines.
 The Droitwich Junction Canal is a narrow canal, opened in 1854, which linked Droitwich to the Worcester and Birmingham Canal.
 Both were built to carry salt, and were abandoned in 1939.
 They have been the subject of a restoration plan since 1973, and the Barge Canal was officially reopened in 2010, while the Junction Canal reopened in July 2011.
 Following the opening of the canal, ownership transferred to the newly created Canal and River Trust
The Birmingham and Warwick Junction Canal is a short canal connecting the Digbeth Branch of the Birmingham and Fazeley Canal in the centre of Birmingham ( ) to the Warwick and Birmingham Canal near Gravelly Hill Interchange ( ).
 It was authorized in 1840 by Act of Parliament to relieve pressure on this connection to the Grand Junction Canal leading to London and opened in 1844.

The South Bay Aqueduct is an aqueduct located in the eastern part of the San Francisco Bay Area.
 It conveys water from the Sacramento-San Joaquin Delta through over forty miles of pipelines and canals.
 It begins in north-eastern Alameda County on the California Aqueduct's Bethany Reservoir serving as the forebay.
 The aqueduct flows along the eastern and southern edges of the Livermore Valley.
 Then it flows through a series of tunnels to an end in the foothills of eastern San Jose, 5 miles (8 km) from downtown San Jose, California.
Miramar Reservoir is a reservoir located in the Scripps Miramar Ranch community of San Diego, California.
 Owned, operated and maintained by the City of San Diego, the reservoir was completed in 1960 as part of the second San Diego Aqueduct project.
 Water flowing south to the reservoir originates from both the Colorado River Aqueduct and the California Aqueduct, brought into San Diego by the San Diego County Water Authority.
The Junction Canal was a canal in the states of New York and Pennsylvania in the United States.
 The canal was also called the Arnot Canal, after the name of its principal stockholder, John Arnot of Elmira, New York.
 The canal was built and operated by a private stock company.
 The canal was partly open in 1854, but the entire length was not finished until 1858.
 The completed canal was 18 mi long and had 11 locks.
 Then intent was to lengthen the reach of the Chemung Canal deeper into Pennsylvania in order to connect to the canal systems there.
 Competition with railroads led to diminished use of the canal.
 In 1865 the canal was severely damaged by a flood.
 In 1866, the stock company was authorized to change its name to the "Junction Canal and Railroad Company," and work commenced in constructing a railroad on its right of way.
 The canal was last used in 1871, and was then abandoned.
The Governor Edmund G. Brown California Aqueduct is a system of canals, tunnels, and pipelines that conveys water collected from the Sierra Nevada Mountains and valleys of Northern and Central California to Southern California.

The Shrewsbury Canal (or Shrewsbury and Newport Canal) was a canal in Shropshire, England.
 Authorised in 1793, the main line from Trench to Shrewsbury was fully open by 1797, but it remained isolated from the rest of the canal network until 1835, when the Birmingham and Liverpool Junction Canal built the Newport Branch from Norbury Junction to a new junction with the Shrewsbury Canal at Wappenshall.
 After ownership passed to a series of railway companies, the canal was officially abandoned in 1944; many sections have disappeared, though some bridges and other structures can still be found.
 There is an active campaign to preserve the remnants of the canal and to restore the Norbury to Shrewsbury line to navigation.
Stretton Aqueduct is a short cast iron canal aqueduct between Stretton and Brewood, and near to Belvide Reservoir, in south Staffordshire, England.
 Designed by Thomas Telford and bearing his name plus its date of construction, 1832, it carries the Shropshire Union Canal (formerly the Birmingham and Liverpool Junction Canal) 30 ft over the A5 road at a skewed angle.
The Harvey O. Banks Pumping Plant is located 2.5 miles (4 km) southwest of the Clifton Court Forebay and 12 miles (19 km) northwest of Tracy, CA.
 The plant is the first pumping plant for the California Aqueduct and the South Bay Aqueduct.
 It provides the necessary fluid head (potential energy) for the California Aqueduct to flow for approximately 80 miles (130 km) south past the O'Neill Forebay and the San Luis Reservoir to the Dos Amigos Pumping Plant.
 The Banks Pumping Plant initially flows into the Bethany Reservoir.
 It is from the Bethany Reservoir that the South Bay Aqueduct begins.
Centreport Aqueduct is a historic aqueduct located in the town of Brutus near Weedsport in Cayuga County, New York.
 The aqueduct was consrtructed in 1854-1857 as a part of the Weedsport section of the "Improved Erie Canal."
 The wood and stone aqueduct carried the Erie Canal over Cold Spring Brook near its juncture with North Brook.
 The aqueduct structure is approximately 125 feet in length, 125 feet in width, and 16 feet in height.
 Improvements were made to the aqueduct in 1895 as part of the "Nine Million Dollar Improvement."
 The aqueduct ceased being used after development of the New York State Barge Canal System in 1917.
 The aqueduct stone work is still intact and is the prime feature of a roadside park constructed by the New York State Department of Transportation in 1972 with the assistance of the Weedsport Lions Club.
