    Cost factor
    *Depending on the load capacity of the substructure, Optigreen "High Density (HD)" or "Low Density (LD)" substrates can be used. Weight specifications refer to saturated conditions; dry weight is approximately 60 - 70 % of the saturated weight.
    **Depends on slope and system solution. Determined at 0° according to FLL guidelines.
    ***Determined according to FLL discharge coefficient measurements using a 15-minute reference rainfall r(15) = 300 l/s x ha.
