Yorkshire Water’s interactive education centre in Sheffield has received national accreditation.
Ewden Water Treatment Works, Wharncliffe Side, has been given a quality award by The Council for Learning Outside the Classroom, which enables teachers to find locations where children can learn away from school.
Children gain hands on experience and learn how tap water is made.
Yorkshire Water’s sites in Headingley and Bradford also received the award.
Since the sites opened, almost 90,000 school children have taken the tour to learn about the water cycle.
