Hydro Excavation Services
Stormwater Management
Hydro excavation provides safe, non-destructive digging for stormwater pipe locating, utility daylighting, and drainage infrastructure exposure. Using high-pressure water and vacuum extraction, this method precisely removes soil without damaging underground stormwater systems. It is ideal for exposing storm sewer lines, culverts, outlet structures, and SCM components during inspections and repairs. Hydro excavation reduces liability, prevents utility strikes, and protects critical stormwater infrastructure assets.
Commercial & Industrial Hydro Excavation Services
Why Choose Hydro Excavation
Safe, Non-Destructive Utility Exposure
Protect underground stormwater pipes, force mains, and buried utilities with precision hydro excavation that reduces utility strikes, service disruptions, and costly infrastructure damage.
Precision Stormwater Utility Daylighting
Accurately expose storm sewer lines, culverts, outlet structures, and underground drainage systems with minimal soil disturbance — ideal for congested municipal and commercial sites.
Faster Stormwater Repairs & Inspections
High-pressure water and vacuum extraction accelerate stormwater pipe locating, inspections, and rehabilitation projects while reducing labor hours and downtime.
Effective in Difficult Conditions
Performs reliably in clay, compacted soil, sandy conditions, and frozen ground, with the ability to reach deep or remote stormwater infrastructure locations.
Minimal Surface & Environmental Impact
Targeted excavation limits pavement damage, protects surrounding stormwater control measures (SCMs), and reduces site restoration costs.
Hydro Excavation Applications
CMS hydro excavation delivers precise, non-destructive digging for stormwater pipes, catch basins, culverts, and underground utilities. Services include potholing, slot trenching, debris removal, deep structure excavation, and cold-weather access for year-round maintenance.

- Manhole & Debris Removal: Remove sediment, slurry, and debris from manholes, vaults, and catch basins efficiently.
- Remote & Limited-Access Excavation: Access tight, congested, or sensitive areas traditional equipment cannot reach.
- Environmental Soil Removal: Precisely remove contaminated soil near stormwater systems with minimal disruption.
Stormwater Systems We Maintain
Catch Basins, Inlets, Frames & Grates
Vactor truck maintenance of catch basins, inlets, frames, and grates removes sediment and debris, restores hydraulic flow, prevents blockages, and ensures stormwater system compliance.
Detention Ponds
Vactor truck services for detention ponds remove accumulated sediment, clean outlet structures, and stabilize embankments to maintain storage capacity, peak flow control, and regulatory compliance.
Retention Ponds
Routine Vactor truck maintenance of retention ponds improves permanent pool conditions, clears debris, restores pollutant settling efficiency, and protects long-term water quality.
Grassed & Rip Rap Swales
Vactor truck cleaning and maintenance of grassed and riprap swales stabilizes erosion, removes sediment, and restores vegetation to maintain hydraulic performance and site compliance.
Hydrodynamic Separators
Vactor truck sediment and debris removal in hydrodynamic separators restores pollutant and hydrocarbon capture efficiency while maintaining proper stormwater flow and compliance.
Level Spreaders
Vactor truck maintenance ensures level spreaders distribute runoff evenly, prevent channelized flow, and protect downstream soils and vegetation for optimal stormwater management.
Outfalls
Vactor truck cleaning and rehabilitation of outfalls removes debris, repairs structural damage, prevents scour, and ensures reliable stormwater discharge and regulatory compliance.
Proprietary Stormwater Systems
Vactor truck services maintain proprietary stormwater systems by restoring filtration media, clearing blockages, and preserving hydraulic performance and permit compliance.
Storm Sewer Systems
Vactor truck maintenance of storm sewer systems removes sediment buildup, clears pipes, and repairs joint deterioration to restore proper drainage and system efficiency.
Stormwater Infiltration Assets
Vactor truck cleaning and maintenance of infiltration assets improves soil permeability, restores runoff absorption, and ensures groundwater recharge and compliance.
Stormwater Vaults
Vactor truck sediment removal and maintenance of stormwater vaults restore storage capacity, repair structural components, and maintain hydraulic performance and regulatory compliance.
Debris Collection Devices
Stormwater inspections of debris collection devices verify trash capture, floatable removal, and downstream protection of stormwater systems.
Underground Stormwater Assets
Vactor truck maintenance of underground assets—including pipes, chambers, and vaults—restores flow, structural integrity, and regulatory compliance.
Above Ground Stormwater Assets
Stormwater inspections of above ground assets ensure proper flow management, erosion control, and accessible maintenance for site compliance.
Permeable Pavement
Stormwater inspections of permeable pavement assess infiltration capacity, surface clogging, and overall drainage performance.
Sand Filters
Vactor truck maintenance of sand filters replaces clogged media, removes sediment, and restores filtration efficiency to ensure pollutant removal and compliance.
Routine/Quarterly Inspections
Routine quarterly inspections of stormwater control measures identify sediment accumulation, debris, erosion, and vegetation issues before they impact system performance. These inspections help maintain compliance, extend SCM life, and ensure effective stormwater management year-round.
Post-Storm Inspections
Post-storm inspections are conducted after significant rainfall events to assess SCM functionality, identify immediate damage, and address any safety or operational concerns. Prompt evaluation after storms prevents flooding, erosion, and costly downstream repairs.
Annual Certified Inspections
Annual certified inspections verify that stormwater control measures are operating according to local regulations and design specifications. These formal inspections provide official documentation for compliance and ensure long-term system performance.
As-Built/Final Inspections
As-built inspections confirm that newly constructed stormwater control measures match approved plans and design requirements. Final inspections ensure proper installation, identify potential construction issues, and validate long-term functionality.
Remedial/Repair Inspections
Remedial inspections assess SCMs after notices of violation, damage, or structural failure to determine required repairs. These inspections guide corrective actions that restore system performance and maintain regulatory compliance.
Key Types of SCM Inspections
Comprehensive stormwater control measure (SCM) inspections are essential to maintain proper function, ensure NCDEQ compliance, and protect water quality across commercial and regulated sites. Routine quarterly, post-storm, annual certified, as-built, and remedial inspections identify sediment buildup, debris, erosion, vegetation issues, and structural concerns before they cause flooding or system failures. By performing these targeted SCM inspections, CMS helps extend the life of stormwater infrastructure, prevent costly repairs, and optimize overall stormwater management performance.
