iLevel's tank monitoring technology is being used by Normet and Barhale on the Elan Valley Aqueduct project. The Elan aqueduct crosses Wales and the Midlands supplying water from the Elan Valley Reservoirs in Mid Wales to Birmingham's Frankley Reservoir for the city of Birmingham.

Barhale, in partnership with North Midland Construction are building three new tunnels at the Elan Valley Aqueduct as part of the Birmingham Resilience Project (BRP). iLevel's tank monitoring system is measuring chemicals used in the tunnel construction. 

This part of the work will see the creation of three new tunnels at Bleddfa, Knighton and Nantmel. The tunnels will bypass some existing sections of the aqueduct which will no longer be used and will continue to guarantee a continued water supply to Birmingham.
