Customer Challenge

A large contractor for one of the UK’s biggest water and wastewater utilities commissioned Enzen to improve its financial performance through improved service delivery.

Working across more than 50,000km of sewer network that services in excess of two million residential consumers, Enzen’s customer is responsible for all the utility’s reactive and smaller repair works, CCTV surveys and sewer-lining activities.

As part of its five-year contract, the customer completes over 75,000 reactive jobs and around 20,000 civil excavation jobs a year for the utility. With a view to continuing the contract through the next regulatory cycle, the customer challenged Enzen to not just improve customer satisfaction and profitability, but expand the range of services it could offer as a contractor.
