Trenches
Trenches are used to delay and transport rainwater to either an LAR (local drainage of rainwater) component or to a sewer. Trenches are available in many types of material and are dug beside garages, and along driveways and building entrances. Furthermore, open trenches can be established on the surface, making the rainwater visible and, thus, providing recreational value.
