Septic Stack Trench Installation (Plan View) Detail

This document is the Septic Stack Trench Installation (Plan View) Detail. A diagram with descriptors and notes explains the septic stack trench.

This Septic Stack Trench diagram shows 12” minimum product width, septic stack, sewer & drain and/or triplewall pipe per local regulations and the distribution box.

Notes explain installation with directions to excavate trenches to proper depth. Smooth irregularities in the excavation because a level/flat surface is required. Lay septic stack pipe in trench and assemble as required. Void pipes are to be placed “butted” next to one another. The distribution pipe is connected between adjacent bundles by a bell coupler. Once pipes are laid in the trench and connected, lay a filter fabric covering the entire system. Backfill septic stack pipes with suitable native material. “Walk in” fill to compact soil along sides of septic stack first for load rating. Cover septic stack to a minimum of 6” of cover. For H-10 load application a minimum of 12” of consolidated material is required. Avoid large rocks or debris in cover material.
