Water tunnels are tunnels (below-ground channels) used to transport water to areas with large populations or agriculture.
 They are frequently part of aqueducts.
 Some aqueducts, such as the Delaware Aqueduct are single long tunnels.
 In other cases, such as the San Jacinto tunnel on the Colorado River Aqueduct, water tunnels form parts of far longer aqueducts.
 In cases where the outflow of a water tunnel is into an existing stream or river flowing to the point of water use, the term aqueduct is less likely to be used, as with the Harold D. Roberts Tunnel from Dillon Reservoir to the North Fork South Platte River.
The Ratle Hydroelectric Plant is a run-of-the-river hydroelectric power station currently under construction on the Chenab River, downstream of the village of Ratle in Doda district of the Indian state of Jammu and Kashmir.
 The project includes a 133 m tall gravity dam and two power stations adjacent to one another.
 Water from the dam will be diverted through four intake tunnels about 400 m southwest to the power stations.
 The main power station will contain four 205 MW Francis turbines and the auxiliary power station will contain one 30 MW Francis turbine.
 The installed capacity of both power stations will be 850 MW.
 On 25 June 2013, Prime Minister Manmohan Singh laid the foundation stone for the dam.
 The project is expected to be complete in February 2018.
 Pakistan has frequently alleged that it violates the Indus Water Treaty but the World Bank has not found fault with it.
The San Diego Aqueduct, or San Diego Project, is a system of four aqueducts in the U.S. state of California, supplying about 90 percent of the water supply for the city of San Diego.
 The system comprises the First and Second San Diego Aqueducts, carrying water from the Colorado River west to reservoirs on the outskirts of San Diego.
 The 70 mi First Aqueduct consists of the pipelines 1 and 2, which run from the Colorado River Aqueduct near San Jacinto, California, to the San Vicente Reservoir, approximately 15 mi northeast of the city.
 Pipelines 3 and 4 make up the 94 mi Second Aqueduct.
 Together, these four pipelines have a capacity of 826 ft3/s .
 The smaller, 12.5 mi Fallbrook-Ocean Branch branches from the First Aqueduct into Morrow Reservoir.
 The La Mesa-Sweetwater Branch originates from the First Aqueduct, flowing into the Sweetwater Reservoir.
Mangahao Power Station is a hydroelectric power station near the town of Shannon, New Zealand.
 After being delayed by war, access roading and foundation testing was started by late 1919 and the station opened in November 1924.
 It makes use of Mangahao River, through a series of tunnels and pipelines totaling 4.8 kilometers, in the Tararua Ranges.
 Mangahao Power Station became the power station for Wellington, Horowhenua, Taranaki, Hawkes Bay, and the Wairarapa.
The Fengning Pumped Storage Power Station is a pumped-storage hydroelectric power station currently under construction about 145 km northwest of Chengde in Fengning Manchu Autonomous County of Hebei Province, China.
 Construction on the power station began in June 2013 and the first generator is expected to be commissioned in 2019, the last in 2021.
 Project cost is US$1.87 billion.
 On 1 April 2014 Gezhouba Group was awarded the main contract to build the power station.
 It will be constructed in two 1,800 MW phases.
 When complete, it will be the largest pumped-storage power station in the world with an installed capacity of 3,600 MW.
 The power station will operate by shifting water between an upper and lower reservoir to generate electricity.
 During periods of low energy demand, such as at night, water will be pumped from Fengning Lower Reservoir up to the upper reservoir.
 When energy demand is high, the water is released back down to the lower reservoir but the pump turbines that pumped the water up now reverse mode and serve as generators to produce electricity.
 The process is repeated as necessary and the plant will serve as a peaking power plant.
The Alpaslan-2 Dam is an embankment dam currently under construction on the Murat River in Muş Province, Turkey.
 The dam is located about 32 km north of the provincial capital, Muş.
 The primary purpose of the dam is hydroelectric power production and irrigation.
 Its power station will have an installed capacity of 280 MW and the reservoir will help irrigate 78000 ha of land.
 Enerjisa Power Generation Inc. acquired the license for the power station from Özışık İnsaat & Enerji in April 2011 and Yenigün Construction started excavating the diversion tunnels May 2012.
 The diversion tunnels are expected to be complete by the end of 2012.
 In late May 2013 Pöyry was awarded the detailed design of the dam, power station, spillway and switch yard.
 Enerjisa expects the project to be complete in 2016.
Guthega Power Station is located in the Snowy Mountains region of New South Wales, Australia.
 The power station's purpose is for the generation of electricity.
 It is the first to be completed and smallest of the initial seven hydroelectric power stations that comprise the Snowy Mountains Scheme, a vast hydroelectricity and irrigation complex constructed in south-east Australia between 1949 and 1974 and now run by Snowy Hydro.
The Snowy Mountains scheme or Snowy scheme is a hydroelectricity and irrigation complex in south-east Australia.
 The Scheme consists of sixteen major dams; seven power stations; two pumping stations; and 225 km of tunnels, pipelines and aqueducts that were constructed between 1949 and 1974.
 The Scheme was completed under the supervision of Chief Engineer, Sir William Hudson and is the largest engineering project undertaken in Australia.
An aqueduct is a watercourse constructed to convey water.
 In modern engineering, the term "aqueduct" is used for any system of pipes, ditches, canals, tunnels, and other structures used for this purpose.
 The term "aqueduct" also often refers specifically to a bridge on an artificial watercourse.
 The word is derived from the Latin "aqua " ("water") and "ducere " ("to lead").
 Aqueducts were used in ancient Greece, ancient Egypt, and ancient Rome.
 In modern times, the largest aqueducts of all have been built in the United States to supply the country's biggest cities.
 The simplest aqueducts are small ditches cut into the earth.
 Much larger channels may be used in modern aqueducts.
 Aqueducts sometimes run for some or all of their path through tunnels constructed underground.
 Modern aqueducts may also use pipelines.
 Historically, agricultural societies have constructed aqueducts to irrigate crops and supply large cities with drinking water.
The Lough Ree Power Station is a large peat-fired power station in Lanesborough, in the Republic of Ireland.
 The station generates up 100 MWe of power, ranking as the Third largest peat-fired power station in the country, after West Offaly Power Station at 150 MWe .
 and Edenderry Power Station at 120 MWe .
 The power station was constructed as a replacement to the ageing 85 MWe Lanesborough power station.

Question: Guthega Power Station is part of a project that has what length of tunnels, pipelines, and aqueducts?
Answer: 225 km
