About Rivelin Works

 

Rivelin Water Treatment Works (WTW) has a treatment capacity of 75Ml/day and serves up to 100,000 customers in south and south-west Sheffield in Yorkshire. An identified increase in raw water colour resulted in the need to enhance the existing Sirofloc treatment process to reduce final manganese levels and safeguard against the formation of trihalomethanes. The £14m project comprised two separate batches: (i) base maintenance, including the replacement of old assets with new, and (ii) new manganese contactors, incorporating the design, construction and commissioning of 6 (No.) manganese contactors. Together the two batches formed the overall scheme at Rivelin WTW and were delivered in collaboration with Yorkshire Water Services as part of their AMP5 Capital Programme.
