Confined Space Entry
Stormwater Management
CMS provides safe, professional confined space entry for stormwater pipes, vaults, and underground drainage structures. Our trained technicians perform inspections, cleaning, and maintenance in compliance with OSHA and local safety regulations. Confined space entry allows for detailed assessment of stormwater infrastructure, detecting blockages, structural defects, and sediment accumulation before they cause system failure. From municipal storm sewers to commercial and HOA drainage systems, our services ensure safe, effective stormwater management and regulatory compliance.
OSHA Certified Confined Space Entry
CMS Confined Space Entry Services & Activities
Inspections & Maintenance:
Perform internal assessments of stormwater pipes, vaults, and manholes to ensure proper flow, detect blockages, and maintain infrastructure functionality.
Cleaning & Desilting:
Remove debris, sediment, and obstructions from underground stormwater systems to optimize hydraulic performance and prevent flooding.
Structural Repairs:
Rehabilitate stormwater infrastructure, including pipe lining, joint repair, and vault restoration, to restore system integrity and compliance.
Emergency Response:
Standby confined space rescue services address immediately dangerous to life or health (IDLH) situations within stormwater pipes and vaults.
CMS Provides Safety & Regulatory Compliance (OSHA)
Permit-Required Entries:
Follow strict OSHA permit-required entry standards with documented programs, permits, and calibrated safety equipment for all confined stormwater spaces.
Atmospheric Testing & Monitoring:
Continuously monitor oxygen, toxic gases, and flammable vapors in stormwater vaults and pipes to ensure worker safety.
Ventilation & Safety Equipment:
Use forced air ventilation, PPE, and retrieval systems—including harnesses and tripods—for safe stormwater confined space work.
Trained Personnel:
Certified entry supervisors, attendants, and entrants perform stormwater confined space operations to minimize risk and maintain compliance.
Stormwater Systems We Maintain
Catch Basins, Inlets, Frames & Grates
Stormwater maintenance of catch basins, inlets, frames, and grates removes sediment and debris, restores hydraulic flow, prevents blockages, and ensures regulatory compliance.
Detention Ponds
Regular stormwater maintenance of detention ponds removes accumulated sediment, cleans outlet structures, and preserves storage capacity and peak flow control for effective flood management.
Retention Ponds
Stormwater maintenance of retention ponds maintains permanent pool conditions, clears debris, supports pollutant settling, and ensures long-term water quality performance.
Grassed & Rip Rap Swales
Stormwater maintenance of grassed and riprap swales stabilizes erosion, removes sediment, and preserves vegetation to protect hydraulic flow and site compliance.
Hydrodynamic Separators
Routine maintenance of hydrodynamic separators removes sediment, trash, and hydrocarbons to restore pollutant removal efficiency and optimal system performance.
Level Spreaders
Stormwater maintenance of level spreaders ensures even runoff distribution, prevents channelized flow, and protects downstream soils and vegetation.
Outfalls
Stormwater maintenance of outfalls removes debris, repairs structural issues, and stabilizes discharge points to prevent scour and maintain regulatory compliance.
Proprietary Stormwater Systems
Maintenance of proprietary stormwater systems restores filtration media, clears blockages, and preserves hydraulic performance and permit compliance.
Storm Sewer Systems
Stormwater maintenance of storm sewer systems clears pipes, removes sediment, and repairs joints to restore proper drainage and hydraulic efficiency.
Stormwater Infiltration Assets
Regular stormwater maintenance of infiltration assets improves soil permeability, restores runoff percolation, and ensures groundwater recharge and compliance.
Stormwater Vaults
Stormwater maintenance of underground vaults removes sediment, repairs structural components, and restores storage and treatment capacity for efficient system operation.
Debris Collection Devices
Routine maintenance of debris collection devices removes trash and floatables, protects downstream stormwater infrastructure, and ensures system efficiency.
Underground Stormwater Assets
Stormwater maintenance of underground assets—including pipes, chambers, and vaults—restores hydraulic performance, structural integrity, and compliance.
Above Ground Stormwater Assets
Stormwater maintenance of above ground assets stabilizes erosion, removes debris, and ensures accessible and compliant system operation.
Permeable Pavement
Routine stormwater maintenance of permeable pavement removes surface clogging, restores infiltration capacity, and maintains stormwater treatment efficiency.
Sand Filters
Stormwater maintenance of sand filters replaces clogged media, removes accumulated sediment, and restores filtration efficiency for pollutant removal and regulatory 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.
