This gallery of photos shows examples of replacement septic systems installed at challenging sites. Each unique site presented challenges including poor soil, steep slopes, shallow depth to rock, or small lot size.

ONSITE’S anthem is to keep the designs as simple as possible, only using more sophisticated approaches when necessary. We've completed hundreds of designs with gravity flow through conventional trenches. This collection of projects highlight some of the more challenging designs.
