Carlsberg Marston’s Brewing Company Adopts to Self-Supply Water for Joint Venture

Last updated: 10th February 2022

Carlsberg Marston’s Brewing Company (CMBC), a joint venture between Carlsberg UK and Marston’s PLC, has applied to market regulator Ofwat for a licence to Self-Supply water to its eight UK breweries in the UK, in a move that supports the company’s ambitious net zero targets.

CMBC is one of the newest, historic brewers in the UK, combining over 300 years of shared values, history and heritage. Reducing water consumption and waste is an integral part of its Together Towards Zero campaign which recognises that demand for water in the UK will outstrip supply within 25 years. Accordingly, it has set a target to reduce water usage at its breweries by 25% during 2022, and go onto achieve a 50% reduction by 2030, eliminating water waste.  

Group Procurement Manager for CMBC, Colin McKenzie, said: “Prior to the formation of CMBC, Marston’s brewery and distribution depots were supplied under Marston’s Self-Supply licence. Each site had its own reporting framework in place utilising AMR data and meter reads sent from the on-site engineers to display live consumption and cost data broken down into each billed service component. This experience amply demonstrated how Self-Supply enables companies like ours to take control over our data to facilitate reductions in water consumption and cost. We simply could not access this granular level of analysis any other way. For this reason, we’re keen to put our combined sites back onto a Self-Supply footing with a new licence at the earliest opportunity. 

“We are determined to use the minimum amount of water throughout the brewing process, and to make the most of every drop. With ambitious targets to reduce our water use and eliminate waste throughout our global supply chain, it is critical for us to have full visibility of our water data. Here in the UK, Self-Supply is the enabler for this and, importantly, it gives us direct access to wholesalers and Waterscan experts who can help us build on our water efficiency programmes.” 

A partnership agreement between CMBC and Waterscan gives CMBC an important seat at the water industry table to build relationships and knowledge across the sector, while Waterscan provides all technical support and services.  

Waterscan’s Rebecca Gale commented, “Self-Supply has proven to be a successful water efficiency strategy for the majority of the UK’s hospitality companies, including Marston’s prior to the formation of its new joint venture. As we are currently providing retail services to the CMBC team, we have avoided any interruption to data gathering meaning that, while Ofwat considers the new combined licence application, efficiency work continues and the transition back to Self-Supply will be seamless.”
