It uses water provided by three reservoirs high up in the Faatautia Valley, above the commune. Each reservoir is created by an embankment dam. Hitia'a 2 Dam at 17°37′44.09″S 149°20′43.56″W / 17.6289139°S 149.3454333°W, which lies at an elevation of 637 m (2,090 ft) above sea level, is 19 m (62 ft) tall. It withholds a reservoir of 110,000 m3 (89 acre⋅ft). Next, at an elevation of 530 m (1,740 ft), Hitia'a 3 Dam at 17°37′51.15″S 149°20′8.57″W / 17.6308750°S 149.3357139°W is also 19 m (62 ft) high but withholds a larger reservoir of 600,000 m3 (490 acre⋅ft). Finally, Hitia'a 1 Dam at 17°37′36.18″S 149°20′11.74″W / 17.6267167°S 149.3365944°W lies at 511 m (1,677 ft) above sea level, is 10 m (33 ft) tall, and withholds a reservoir of 11,000 m3 (8.9 acre⋅ft). Water from the reservoirs is sent to the power station via a 11.5 km (7.1 mi) long penstock. The power station contains an array of six Pelton turbine-generators which include a 300 kW, 140 kW, 100 kW, 1 MW and two 3 MW units.[2][3]
