SUEZ Switch Over 200 Sites To Castle Water For Optimised Services And Solutions

Optimum services and solutions

The objective: To consolidate their portfolio with one retailer that can provide optimum services and solutions, and fix billing problems caused by previous market errors. 

Castle Water prioritised a data cleanse of SUEZ’s entire portfolio to rectify the inherited market errors and ensure accurate billing. To cater to SUEZ’s multi-site needs, Castle Water implemented its consolidated billing solution to simplify billing and improve cost management. 

The result: SUEZ now has confidence in its water, wastewater, and trade effluent charges.

Julie Swanepoel, Procurement Officer at SUEZ, said: “Castle Water continue to provide exceptional service and support. Consolidating all our sites with Castle Water has generated real efficiencies and cost savings, and they deliver vital support in the management of our business water across the UK. Their additional water services and water efficiency measures offer added value and environmental benefits and highlight our aligned sustainability values.”
