Utilities – Storm Infiltration
GBD LLC provides professional stormwater infiltration system installation for residential, commercial, and municipal projects across King, Pierce, Kitsap, Mason, and Thurston Counties. Our team designs and installs systems that manage rainwater on-site, reduce runoff, and protect local waterways.
With over 30 years of excavation and utility experience, we make sure your storm infiltration system is built to meet engineering specifications, local regulations, and environmental standards.
Stormwater management is critical in Western Washington’s rainy climate. We install infiltration trenches, dry wells, soakage pits, and rain gardens to help water soak into the ground naturally. Our systems reduce strain on storm drains, limit flooding, and protect foundations from water damage.
Built for Local Conditions
We understand the challenges of our region’s heavy rainfall and varied soil types. Our crew works closely with engineers, surveyors, and inspectors to ensure each system meets local drainage codes and performs effectively year-round.
Safety, Compliance & Quality
We follow all permit requirements and environmental regulations, including sediment control and erosion prevention measures. Every project is completed with precision to ensure long-term performance and compliance with city and county codes.
