MWH Treatment

Who are MWH Treatment?

 

MWH Treatment, or sometimes just referred to as MWHT, are a team of passionate professionals dedicated to delivering sustainable water and wastewater solutions across the UK. With over 200 years of heritage, MWHT has evolved into a trusted partner in the UK water industry, known not just for our technical expertise, but for their collaborative spirit and commitment to doing the right thing for their clients, communities and the environment. 

What brought MWHT into the @one Alliance?

MWHT, at the time using the name BiWater, joined the Alliance as a founding member in 2005. To them, the Alliance provided an opportunity to be part of something transformative. Our Alliancing model challenged traditional delivery methods and put collaboration at its core.  

This innovative model, refined over the last 20 years, aligned perfectly with MWH’s own values. Believing in our vision for a truly collaborative, integrated Alliance, MWHT knew its people, experience and culture of innovation could help bring it to life. Since then, MWH have been proud to help shape the Alliance into one of the most respected delivery models in the sector.  

“The @one Alliance represents a shared commitment to doing things better – through collaboration, innovation and trust. From the very beginning, we’ve played a key role in shaping its direction and success. It reflects the way we work at MWH: focused, forward-thinking and always striving to deliver the best outcomes for our clients and communities.”

By working together, MWH’s values meld seamlessly with Anglian Water’s values that together we: are Always Exploring, Build Trust & Do the Right Thing.
