Soakaway 1 Design Calculation:-
Proposed roof design area (dispersing to Soakaway 1) 19.85 x 1.5 (45° roof pitch) = 29.775
Proposed design area x rainfall (0.040) 29.775 x 0.04 = 1.191M³
Typical Pre-formed storage Cells / Crates 1000mm x 500mm 400mm = 0.2M³

Provide 1no. Soakaway 1000mm x 1500mm with a minimum of 6no. Cells / Crates
Soakaway 2 Design Calculation:-
Proposed roof design area (dispersing to Soakaway 2) 64.94 x 1.5 (45° roof pitch) = 97.41
Proposed design area x rainfall (0.040) 97.41 x 0.04 = 3.896M³
Typical Pre-formed storage Cells / Crates 1000mm x 500mm 400mm = 0.2M³
