The Althon standard range of headwalls can accommodate pipework up to 2100mm. We can precast multiple pipe openings into our outfalls if required. As standard we will cast in the pipe openings 100-150mm above the spillway. However we are able to cast in the opening for the connecting pipe or pipes anywhere on the backwall or in the wingwalls (sidewalls). Drainage pipes discharging into open watercourses should be fitted with a concrete headwalls. Althon's standard concrete headwalls are fast and easy to install.
