    *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. In accordance with the requirements of the FLL guideline, the specified weight does not take temporary water accumulation into account.
    **For the calculation of the dimensions of the pipe we recommend the discharge coefficient Cs = 0.1. Cs= 0.01 determined for 2 % according to the FLL guideline.
    ***Determined according to FLL discharge coefficient measurements using a 15-minute reference rainfall r(15) = 300 l/s x ha.
