AHJ Relationships
Castle has built strong working relationships with Authorities Having Jurisdiction (AHJs), streamlining stormwater quality management approvals for our clients. We understand the requirements and preferences of local, state and federal regulators. That knowledge shapes every stormwater treatment system we build.
SWPPP Compliance
For projects requiring a Stormwater Pollution Prevention Plan, Castle is an experienced SWPPP contractor. A complete SWPPP addresses storm drain protection, site perimeter controls and regular compliance inspections. We help clients meet permit conditions, coordinate erosion and sediment controls and document compliance throughout construction. Our familiarity with AHJ expectations reduces delays and keeps projects moving.
Stormwater Systems Built for Every Site
Castle installs stormwater treatment systems across a large range of construction sites and project types. We build sediment traps to capture runoff at the source during active earthwork. Castle's hydrodynamic separators remove oils, sediment and debris from stormwater before runoff reaches discharge points. We also install bioretention basins and underground detention systems for lasting water quality performance. Learn more about our stormwater management approach.
