DECAL FOR RELEASE TUNNEL 150
Lids for the infiltration tunnel 150
Rainwater and wastewater infiltration systems with a deflector
At the beginning of the tunnel thread, a lid fitted with a deflector is mounted. The deflector's task is to absorb the hydraulic impact of the sewage or water supplied. By using it under tunnels, there is no leaching of soil in the place of inflow of sewage or water. The lid is also mounted at the end of the tunnel thread.
