454:. Investigations were undertaken into how best to do this, with consideration given to trucks, horse-pulled carts, traction engine as well as transporting it up the Waiau River which would require some blasting to remove hazards. The decision was made to employ a traction engine and two trucks which required SEPB to upgrade the existing roads and also extend them to the construction site. Until the road was completed material was brought in by horses pulling wagons. In 1920 Alfred Pryde Walker (1891â1953) was appointed the resident engineer in charge of construction. Walker had experience as an engineer in Canada, South Africa, Ceylon, Fiji and Australia (where he had worked with Hay). By the end of 1920 a total of 80 men and 40 horses were working in the project, building the road and preparing the sites for the construction camp and powerhouse. A Boving water wheel was established on site to provide power to the construction camp, but it was switched off at 10:00 pm. A timber mill was established on Diggers Hill on the Western side of the Waiau River to provided timber for the project. By early 1921 not only was the access road to Lake Monowai completed but also the construction camp as well as a new suspension bridge across the Waiau River at Sunnyside. Up until the completion of the bridge material and men had been conveyed across the river by a ferry.

without interfering with the power station's operation. The flooding also caused damage to the approaches to the bridge over the Waiau which allowed the river to scour around the bridge's pillars. As a result, extensive remedial work was required. the only upside of the heavy rainfall was that Lake
Monowai rose 9.5 ft (2.9 m) which confirmed that the dam and control gates were up to the task. A car was driven the length of the pipeline once it was completed. However once the pipeline was filled with water for the first time it was found to be deflecting by up to 7 in (180 mm), which caused some of its supporting cradles to crack. The issue was fixed by installing additional cradles. When the surge chamber was filled with water for the first time it was found to leak badly, but Alfred Walker solved the problem in the short term by putting oatmeal in the water which swelled up and sealed the cracks. By 15 December 1924 the powerhouse and head works were completed, the turbines were running and the generators were drying out and the switchgear cabled, leaving only minor work required.

they were no longer prepared to guarantee to fund SEPB. In compliance with the government directives to reduce expenditure
Lawrence Birks who was by now Chief Engineer of the Hydro-Electric Branch of the Public Works Department wrote to SEPB on 19 April 1921 that with expenditure of £100,000 to date and contracts in place for another £100,000 they had to reduce capital expenditure in order to ensure that the supply and reticulation become profitable as easily as possible. Therefore, while he wanted Monowai to be completed it was necessary to reducing the area that was to be supplied and to change the system of charging consumers in order to reduce the total cost to £600,000. In response, Hay and Vickerman were requested by SEPB to provide a detailed estimate for a modified scheme costing £600,000. In June 1921 they replied with an estimate of £700,000 which lead the board to instruct Sir Joseph Ward who was then in London to arrange a load for £750,000.

of the
Monowai River a raised trestle tramway was built southwards across the lakes natural outlet to convey construction materials and the workforce to the arm of the lake where the control gates were built. Once they had been finished the area under the trestle tramway was lined with timber to hold back the water as the area was filled with earth. the core of the dam was formed from two rows of steel-shod piles driven seven feet into the rock. These were surrounded by clay in bags and then sheathed in totara timber. The remaining fill consisted of unreinforced concrete, broken up rock, sand, and silt. The lake side surface of the dam was faced with rip-rap (ungraded pit gravel) which was later plant with willows to control the impact of waves on the dam. Later the downstream face was sown with clover and grass.

The election of Alexander Rodger (1872 â ?) as the league president re-galvanized the league and saw it clear its debt. In 1917 the government in response to the league's request dispatched engineer Lawrence Birk (1874â1924) from the Public Work Department on the first of two visits (20 to 28 September and 1 to 8 December) to investigate the demand for electricity and potential for hydro-electric generation in Southland.

both Hay and
Vickerman during the early stage of the work, their estimates were proving to be too low, progress was slow on upgrading the roads to allow their use in winter, materials were being purchased before they were required and at high prices. The cancellation of the contract would eventually lead to arbitration, which resulted in SEPB having to pay the firm 2% of the capital costs. While five staff members of Hay and Vickerman's staff were employed by SEPD, 112 men working at Monowai were let go. Ward meanwhile in July 1921 managed to obtain a loan for £750,000 at an interest rate of 6%, which would be guaranteed by the New Zealand Government.

roiled plates were then dripped in a boiling pitch and tar to protect them then riveted in 6 ft (1.8 m) long sections before being transported to required location for mounting on a cradle. Progress had reached the point by this time that SEPS placed orders for the turbines, valves, generators, exciters and switchgear. Due to poor economic conditions the total cost of £19,859 was well under what the quotations they had received two years earlier. The equipment suppliers were Boving, turbines and valves, English
Electric, generators and exciters; Reyrolle, switchgear.

The water would flow through the control gates to a headpond where a weir would divert it into a canal to carry the water to a shortened steel pipeline.

Monowai village burnt down, with a replacement opening in 1951. The generator winding began giving problems and were repaired in 1954, 1957 and 1958. In 1958 following damage from cavitation the runners of the turbines were repaired. In 1955 a fire briefly closed the power station.

As a result, TPCL had no choice but to reluctantly sell the power station, which they did in March 1999 to Trustpower for $ 3.75 million.

In his report submitted in March 1910 he had identified that while Monowai would provide the cheapest power its distance from Invercargill (which would require the building of lengthy transmission lines) coupled with the demand meant it would be more feasible for the borough to continue using its existing coal powered power station.

During the Second World War the Monowai power scheme was regarded as being of strategic value, which meant that a blackout was applied to the powerhouse and village, with sentries at the bridge and nighttime patrols of the pipeline and canal.
