The source of the water supply is sufficient also to provide the borough with an electric installation. The pipes conveying the supply from the Waiwakaiho river are carried over the brow of the hill to the power-house. This gives a fall of about 170 feet, and drives 2 turbines of about seventy horse-power each. These are coupled direct to two forty-five kilo-watts, 2000volt, single phase generators. From the power-house there are about four miles of overhead lines, which convey the electrical energy to the distributing station, at the corner of Lemon Street and Liardet Street. Thence the lines are led on the three-wire system, to supply the street lamps and private lighting of the borough; most of the street lights are of the incandescent variety; 110 are glow lights, and ten are arc lights. The cost of the whole installation exceeded £13,000.
