Expert Septic system installation in Polk County, OR

A new septic system installation in Polk County starts with understanding your land. Polk County soil varies widely, and system size is based on soil characteristics and the number of bedrooms in your home. A site evaluation defines where the system can go and how large the drainfield needs to be. Iron Edge Excavation handles the excavation, tank placement, distribution line installation, and drainfield construction. Rural properties across Polk County, Marion County, Yamhill County, Benton County, and Lincoln County often sit well outside municipal sewer reach, making a properly installed onsite system the only option. Saturated soils during Oregon's wet season can stress a poorly sited system, so correct placement and drainfield sizing matter from day one. We serve homeowners in Dallas, Monmouth, Falls City, Grande Ronde, Salem, Albany, Otis, Lincoln City, McMinnville, Amity, Sheridan, Willamina, Stayton, and Silverton. Call Iron Edge Excavation to get your installation started.
