Schneider Electric has been awarded a £205,000 contract to provide variable speed drives, transformers and ring main units to KMI Water for the development of the St Helen’s wastewater treatment plant in Merseyside.
The company will supply the products through its three global brands – Merlin Gerin, Square D and Telemecanique. These products include 15 Telemecanique Altivar VSDs, ranging from 29 to 315kW, for blower and feed-pump applications; three Merlin Gerin 800kVA and three 1,000kVA transformers; and three Merlin Gerin RN2 ring main units. The VSDs in each motor control centre are fitted with active harmonic filters.
The plant will serve around 138,000 people and should treat 127 million litres of sewage a day when it enters service in March 2005.
KMI Water is developing the plant as part of a £245m United Utilities project to renew the west Lancashire and north Manchester water industry infrastructure.
