Development of a new 150kW hydro machine installed in the water supply system for Auckland, New Zealand’s largest city.
MTL was responsible for the project management, detailed mechanical, civil and structural design, construction management, and commissioning of this 150kW mini hydro. MTL’s role also included the selection of a Erhard needle pressure reducing valve in parallel with the mini hydro.
The control system seamlessly coordinates the operation of the mini hydro and the bypass valve to provide the correct water supply flow rate in the most energy efficient manner.
