DISTRIBUTION BOXES

For evenly distributing flow. Dart designed the distribution boxes to allow filtered effluent from septic tanks to be evenly split into a number of trenches. Effluent design manuals state that trenches (up to 600mm wide) are more efficient than beds (over 600mm wide) and therefore you require more trenches than beds for the same square area of soakage. This is why we have designed and manufactured the Dart Distribution box available in sizes from 2-way splitter to 8-way splitter. All distribution splitter boxes come with a concrete lid. Risers also available.

Sizes 2-way, 3-way and 4-way splitter (diam. 300mm).
Sizes 5, 6, 7 and 8-way splitters (diam. 400mm)
Standard height 400mm.
Outlet diam. 90mm
