Sewer Line Extension

Sewer excavation is not a task for just anyone – it’s a complex process that requires significant expertise in equipment handling, sewer line safety protocols, and much more. With a fatality rate 112% higher than that of general construction, excavation work should be left to the pros and planned ahead. At Rainstate Earthwork, we’re a local Washington excavation company with years of sewer excavation, replacement, installation, and repair experience. We will:

  • Evaluate and inspect soil for excavation and sewer line placement
  • Locate underground utilities such as natural gas lines
  • Test for low oxygen, hazardous fumes, and toxic gases in the excavation area
