16in Hi Capacity Biodiffuser At Grade Installation Detail

This document is 16in Hi Capacity Biodiffuser At Grade Installation Detail. A diagram with descriptors and notes explains the biodiffuser.

This biodiffuser diagram shows the native backfill or approved fill and the dimensions around the unit. Width includes 2” if side wall distance.

Notes explain installation with directions to excavate trenches to proper depth. Smooth irregularities in the excavation because a level/flat surface is required. Assemble biodiffuser leaching chambers and universal endplates together in trenches. Install universal end cap and secure in place with backfill. Punch out pipe hole openings in the end plates and connect inlet pipes. Fill sidewall area to top chambers with native soil. “Walk in” fill to compact soil along sides of biodiffuser for load rating. Cover biodiffuser leaching chambers to a minimum of 12” cover. Avoid large rocks or debris in cover material. Cover heights are impacted by both soil type and compaction.
