How Does Underground Utilities Work in Yakima Valley?
The process starts with thorough site assessment and utility location services to identify existing lines and plan optimal routing for new installations. We coordinate with local utility providers and obtain necessary permits before excavation begins, ensuring compliance with municipal requirements. Our crew uses precision excavation techniques to reach proper depths while protecting surrounding infrastructure, whether we're installing water service lines from the main to your building or laying sewer laterals that connect to the municipal system.
Each utility line is installed with appropriate bedding material and backfill to prevent settling or damage, and Tri-Valley Construction Inc pressure-tests all water lines before final connection. Sewer lines are installed with correct slope grades to ensure proper flow and prevent backups, and we conduct camera inspections to verify alignment and connection integrity. Utility lines receive protective measures against freezing, root intrusion, and ground movement common in Yakima Valley soil conditions.
Final inspections by local authorities confirm that all work meets code requirements before we restore the site and return your property to full use.
