Importance of Stormwater Management

Stormwater management is a critical part of protecting property, infrastructure, and natural resources by controlling runoff volume and reducing pollutants carried by rainwater. Engineered stormwater control measures (SCMs) such as wet ponds, bioretention basins, infiltration systems, and swales are designed to treat runoff, reduce erosion, and improve water quality before water enters streams, rivers, and lakes. Without effective stormwater management, uncontrolled runoff can cause flooding, property damage, and increased sedimentation in receiving waters, leading to non-point source pollution concerns. For commercial, industrial, and regulated sites across North Carolina, proactive stormwater management supports regulatory compliance and reduces long-term operational risks. CMS provides comprehensive stormwater solutions that help property owners plan, implement, and maintain stormwater systems to protect assets and meet performance expectations.

Maintenance of Stormwater SCMs

Routine maintenance of stormwater SCMs is essential for long-term performance, as sediment buildup, vegetation overgrowth, and clogged inlets can significantly diminish treatment capacity and hydraulic function. Regular maintenance ensures that SCMs, such as wet ponds, permeable pavements, and sand filters, continue to capture and treat stormwater runoff as designed. Without ongoing care, SCMs can fail to remove pollutants effectively, increasing the risk of flooding and environmental impacts downstream. CMS provides scheduled maintenance programs tailored to each SCM, helping clients avoid costly failures and ensuring reliable stormwater performance.

Repairs of Stormwater SCMs

Stormwater SCM repair services are critical when systems demonstrate structural issues, sediment reduction in storage capacity, or impaired hydraulic performance. Repairs may involve restructuring outlet controls, restoring eroded embankments, replacing damaged components, or rehabilitating clogged media in filtration systems. Timely SCM repairs prevent small issues from developing into system failures that compromise water quality and increase risk of flooding. CMS delivers stormwater system repair expertise that addresses both routine and non-routine corrections to restore SCMs to their original operating condition.

Inspections of Stormwater SCMs

Stormwater SCM inspections identify maintenance needs, structural concerns, and performance deficiencies that could reduce treatment effectiveness or lead to regulatory non-compliance. Quarterly, annual, and post-storm inspections help owners track sediment accumulation, vegetation conditions, and hydraulic function to ensure SCMs operate as intended. CMS utilizes certified stormwater inspectors and documented inspection protocols to provide thorough evaluations and detailed reporting. These professional inspections support stormwater compliance goals and help guide maintenance and repair planning for each SCM device.
