Cronfeydd Gwydir Reservoir, Wales 

Althon have recently supplied several headwalls factory fitted with bespoke penstocks to Cronfeydd Gwydir Reservoir, Wales. 

Althon are able to pre-fit flow control devices such as flap valves, penstocks and Wastop valves to our precast headwalls.

All accessories are factory fitted at our works meaning the concrete does not have to be drilled on site. This saves time on the installation and has great health and safety benefits.
