Septic & Underground Site Work
Septic installation and site preparation with the excavation work handled together
Whiteout provides septic-related excavation and site preparation in Leavenworth, Cashmere and Wenatchee and throughout Chelan County, with additional project coverage across the region based on scope. Septic work is naturally connected to grading, access, drainage and restoration, so we approach the project as a complete site rather than an isolated hole in the ground.
Septic and site-prep capabilities
- Septic system excavation and installation support
- Tank and component excavation
- Drainfield and trench preparation
- Site clearing and access preparation
- Grading and drainage corrections
- Backfill, cleanup and surface restoration
Plan for the whole property
Septic projects often affect driveways, slopes, drainage paths and future use of the site. Coordinating those details during excavation can reduce rework and leave the property better prepared for the next phase.
For grading, drainage, driveways, trenching and other earthwork, see our excavation and site-work services.
Service area: Leavenworth, Cashmere and Wenatchee, with project-based coverage throughout Chelan and Douglas counties.
