Proprietary Filtration Device Maintenance Services

CMS provides maintenance for proprietary stormwater filtration devices across North Carolina including StormFilter and similar systems. These devices use engineered cartridges to remove sediment, nutrients, and pollutants from stormwater runoff. Over time, filtration cartridges become clogged and require replacement to maintain treatment performance. CMS technicians inspect, clean, and replace filter cartridges to restore system function. Routine maintenance ensures these systems continue meeting stormwater treatment standards.

Stormfilter Maintenance Notes

Proprietary filtration systems require specialized maintenance procedures depending on manufacturer specifications. CMS technicians inspect device chambers and replace filtration cartridges when necessary. Routine service ensures optimal pollutant removal performance.

Maintenance Tasks

Inspect outlet control structures

Stormfilter Inspection Services

CMS performs proprietary device inspections to evaluate cartridge condition and sediment accumulation. Inspectors verify system flow and structural condition. Inspection reports identify maintenance needs and cartridge replacement schedules.

Stormfilter Repair Services

CMS repair crews address structural damage, inlet failures, and cartridge system issues. Repairs may include chamber cleaning, structural repairs, or replacement of damaged components. Proper repairs restore filtration performance.

Stormfilter Frequently Asked Questions

How often should StormFilter cartridges be replaced?
Replacement frequency varies but is typically every one to three years depending on sediment loads.

Do proprietary stormwater devices require maintenance?
Yes. Filtration cartridges and internal chambers require regular inspection and maintenance.

Does CMS service StormFilter systems?
Yes. CMS performs inspections, cartridge replacement, and device cleaning.

What happens if filtration cartridges are not replaced?
Clogged cartridges can reduce treatment performance and cause system bypass.

Are proprietary filtration devices common in North Carolina?
Yes. Many commercial developments use proprietary devices to meet stormwater treatment requirements.

Underground SCM Maintenance, Repairs, and Inspections

Stormwater Maintenance – Underground SCM Devices

Routine maintenance of underground stormwater control measures (SCMs) such as vaults, pipes, and chambers ensures these systems continue to manage runoff and treat water effectively. Services include sediment removal, debris clearing, and monitoring for blockages to maintain proper hydraulic performance. CMS provides scheduled maintenance programs throughout North Carolina to protect system functionality and prevent costly failures.

Compliance, Longevity & Sustainability:
Regular maintenance helps property owners meet NC DEQ and local stormwater permit requirements by keeping systems fully operational. Preventing sediment buildup and minor damage extends the service life of underground SCMs. Well-maintained systems improve water quality, manage runoff efficiently, and support long-term environmental sustainability.

Stormwater Repairs – Underground SCM Devices

Underground SCM repairs address structural damage, clogged pipes, damaged vaults, or eroded chambers that compromise system performance. Timely repairs restore full hydraulic capacity and ensure water quality treatment goals are met. CMS offers targeted repair solutions to return underground systems to optimal operation while minimizing disruption to surrounding properties.

Compliance, Longevity & Sustainability:
Prompt repairs ensure systems remain compliant with regulatory requirements and avoid penalties. Restoring structural integrity protects the long-term durability of the underground infrastructure. Efficient repairs reduce material waste, extend asset life, and maintain sustainable stormwater management practices.

Stormwater Inspection – Underground SCM Devices

Professional inspections of underground SCMs include structural evaluations, sediment and debris assessments, and hydraulic performance checks. Regular inspections identify developing issues such as clogs, damage, or decreased flow before they escalate into major problems. CMS provides detailed inspection reporting to support maintenance planning and regulatory documentation requirements.

Compliance, Longevity & Sustainability:
Routine inspections demonstrate due diligence and help property owners comply with NC DEQ and local stormwater regulations. Early detection of deficiencies reduces long-term repair costs and maximizes the lifespan of underground assets. Properly inspected systems ensure continued pollutant removal, efficient runoff management, and environmentally responsible operations.

Routine/Quarterly Inspections

CMS provides routine quarterly stormwater inspections to evaluate stormwater control measures, verify BMP functionality, ensure regulatory compliance, and identify sediment buildup, erosion, or drainage issues.

Our inspectors document stormwater infrastructure conditions, photograph deficiencies, and recommend maintenance actions to maintain stormwater management system performance, protect water quality, and meet municipal compliance requirements.

Post-Storm Inspections

CMS conducts post-storm stormwater inspections after significant rainfall events to evaluate stormwater control measures, detect erosion, sediment displacement, flooding impacts, and structural damage affecting system performance.

Our stormwater specialists assess drainage structures, detention basins, conveyance systems, and BMP components to ensure proper operation, regulatory compliance, and long-term stormwater management effectiveness.

Annual Certified Inspections

CMS performs annual certified stormwater inspections conducted by qualified stormwater professionals to evaluate stormwater BMP functionality, structural integrity, maintenance needs, and regulatory compliance documentation.

Our certified inspectors provide detailed stormwater inspection reports, compliance verification, maintenance recommendations, and documentation required by municipalities, permitting authorities, and environmental regulations.

As-Built/Final Inspections

CMS conducts as-built and final stormwater inspections to verify stormwater control measures are constructed according to approved engineering plans, specifications, and stormwater management permits.

Our inspection team confirms proper installation of drainage infrastructure, detention systems, and stormwater BMPs, ensuring compliance with design standards before project closeout or regulatory approval.

Remedial/Repair Inspections

CMS performs remedial and repair stormwater inspections to identify damaged stormwater infrastructure, failing BMPs, sediment accumulation, and drainage deficiencies requiring corrective maintenance or rehabilitation.

Our stormwater inspection specialists evaluate repair effectiveness, verify stormwater system functionality, and ensure remediation actions restore stormwater management performance and regulatory compliance.
