Who We Are

Waterframe Limited was established in 2005 to acquire the international business operations of Bristol Water, a privatised UK water utility. We haven't stopped since, and continue to deliver NRW reduction projects and NRW technical assistance expertise to our long list of clients.

Our team consists of highly qualified and motivated professionals, who are all experts in their field. With many years of experience in the industry, they have the expertise to provide comprehensive, first-rate services to our clients.

NRWManager, our class-leading SaaS NRW management solution, is already deployed for public water utilities in SE Asia and USA and is helping those utilities to meet their economic level of losses goals.

We work with local consultants and contractors to build NRW reduction capacity and many of our trainees have gone on to become senior water industry managers in their own right.
