Auma actuators have supported a major refurbishment of Boughton Water Treatment Works in Chester, UK. The scheme illustrates Auma’s comprehensive product portfolio, the benefits of its modular technology and its capabilities in providing a retrofit service. A selection of actuation technology was managed by Enpure and over 80 Auma actuators have been supplied including quarter-turn and multi-turn products. Remote-mounted electric actuator control systems have been installed for valves with restricted access and Auma has provided actuation for penstocks. The focus of this project centred on upgrading a treatment plant. Suppliers needed to work within the constraints of available space between existing structures and it was essential that the water supply was maintained while new technology was installed. The new valve control technology was installed on site without a break in the water flow. The Enpure-Morrison Consortium was appointed contractor for the project by Dee Valley Water.
