Tacoma Creek Build Co. provides turnkey utility installation services for residential and commercial properties throughout the Inland Northwest, including septic systems, water line installation, power trenching, and underground infrastructure. Our team coordinates with engineers, health departments, and inspectors to ensure code-compliant installations from design through final approval. Serving Spokane, Coeur d'Alene, Sandpoint, and Newport, we specialize in mountain properties where challenging terrain, rocky soils, and environmental regulations require experienced contractors. From conventional septic drainfields and pressure distribution systems to deep utility trenches and pump station installations, we handle the full scope of underground infrastructure. Every utility project includes professional locating, engineered trenching, proper bedding and backfill, and thorough compaction to prevent settling and ensure long-term performance.

Safe, code-compliant trenching for all underground utilities with proper depth, bedding, and backfill.
