third phase consisted of the headwater dam Sullana which is 75 m long, has a maximum height of 12 m and has gates with a total capacity of up to 5,000 m3/s; the headwater channel Norte with a capacity of 25,500 m3/s over 56 km which irrigate 150 km2; the channel Sur which is circa 35 km long with a capacity of 7 m3/s for irrigation of about 70 km2 (in total about 5,000,000 m3 excavation); about 60 km of dykes along the regulated river bed in the lower Chira flow (about 5,500,000 m3 of embankment). Phase 4 (2002 to 2004) The final phase included the 12.5 MW Curumuy dam and power plant, completed in 2000; the 15.4 MW Poechos I Hydroelectric Project which was completed in 2004. Capacities The capacity of the reservoir is 1,000,000,000 m3, its catchment area 14,000 m2, its maximum depth 46 m. The irrigation dam is 49 m high and 9 km wide at crest and at its bottom has a conduit to discharge water at a rate of 4 m3/s. The original design brief was to revitalise the Piura valley, which was short of water, and provide modern irrigation for approximately 350 km2 of arable land. The Poechos I Hydroelectric Plant is operated by Sindicato Energético S.A (SINERSA). The Poechos I power house has 15.4 MW in installed capacity and generates 60 GW·h annually for Electronoroeste, the concessionary for energy distribution in northwestern Peru. The power plant is to accomplish a 90% national electrification level of the country by the year 2010 by using a zero emission energy source.
