Althon was asked to replace a trash screen to a brickwork culvert in a wooded area. The original had become distorted over time and was no longer fit for purpose as it regularly became blocked with leaves and other debris.

Althon manufactured and delivered a multi–level cranked trash screen with a mesh walkway for maintenance. A pedestrian guardrail and step irons for safe access to inspect the lower section of the trash screen were also provided.

Althon has a large range of standard trash screens and outfall safety grilles manufactured to comply with various standards, such as Sewers for Adoption and Sewers for Scotland. Bespoke trash screens and gratings are also made to order.
