Powering and Transforming Sustainable Water Infrastructure Our transformers play a crucial role in the water sector, ensuring the smooth operation of wastewater treatment works (WwTW), sewage treatment works (STWs), and water treatment works (WTW). By adjusting voltage levels to power water pumps, motors, and other equipment, they ensure optimal performance across all systems. In addition to voltage regulation, transformers guarantee reliable power delivery to critical water infrastructure, preventing service downtime, such as water distribution and water treatment. Moreover, Transformers like Wilson e4 contribute to increased energy efficiency by optimising power usage, reducing energy losses, and supporting sustainable practices in water utilities. We understand the main challenges in the water market sector: Energy efficiency aims to reduce costs and minimise environmental impact. Grid stability is crucial, and transformers safeguard a steady power supply for water infrastructure and seamless service delivery Ageing infrastructure requires urgent upgrades with modern transformers enhancing efficiency and reliability, minimising the risk of outages or failures. We are a leading provider of transformer solutions, including in the water sector.
