Stormwater Drainage Systems in North Carolina

North Carolina’s stormwater drainage systems face constant stress from steep terrain, clay-heavy soils, saturated ground conditions, and increasingly intense rainfall. When storm drains collapse, pipes separate, catch basins clog, or outfalls fail, properties face flooding, sinkholes, erosion, and costly infrastructure damage.

Ecological Improvements provides full-service stormwater drainage assessment, repair, replacement, cleaning, and installation for HOAs, golf courses, commercial properties, industrial facilities, and municipal systems across North Carolina. Our solutions are engineered for the state’s diverse drainage challenges—from mountain slopes to coastal lowlands.

Why Stormwater Drainage Systems Fail in North Carolina

North Carolina’s conditions create unique drainage vulnerabilities:

  • Red clay soils that compact poorly and cause pipe misalignment

  • Steep mountain slopes increasing flow velocity and erosion

  • Sediment migration burying outfalls and restricting flow

  • Root intrusion from dense vegetation

  • Aging drainage systems in older developments

  • Heavy rainfall overwhelming undersized systems

  • Improper grading during construction

  • Poorly maintained catch basins and conveyance paths

These issues result in:

  • Flooding of streets, yards, fairways, and common areas

  • Standing water and mosquito breeding area

  • Sinkholes and surface failure

  • Washed-out slopes and eroded channels

  • Blocked, collapsed, or separated pipes

  • HOA complaints and regulatory violations

North Carolina Stormwater Drainage System Services

Storm Drain & Pipe Work

 Repair and replacement of failing storm drains and pipes, including excavation, correction of bedding issues, compaction, and structural restoration.

Storm Drain Replacement

 Removal and installation of storm drains damaged by erosion, soil movement, or age—built to correct grade and slope for long-term performance.

Drain Pipe Installation

 Installation of new drainage systems to redirect water, improve flow, and eliminate recurring flooding and erosion.

Storm Pipe Inspections — Camera & Jetting

 High-resolution camera inspections identify structural failures, blockages, root intrusion, and sediment buildup. Jetting restores capacity by clearing pipes.

Catch Basin Repairs & Rebuilding

 Reconstruction of damaged or sinking catch basins, sealing infiltration points, restoring structural integrity, and stabilizing surrounding soils.

Catch Basin Cleaning / Hydro-Vac

 Hydro-vac cleaning removes sediment, debris, and vegetation to restore flow capacity and prevent backups.

Outlet Control Structure Cleaning

 We remove sediment, vegetation, and obstructions buried around outfalls, restoring safe and efficientdischarge.

Our Process — Designed for North Carolina Soil & Terrain

1. Initial Consultation

We inspect drains, pipes, outfalls, channels, and catch basins to identify failures, sediment issues, structural concerns, and erosion risks.

2. Estimate

Clear, detailed estimates based on excavation needs, soil type, equipment access, and drainage complexity.

3. Custom Plan Development & Design

We design a drainage correction plan accounting for NC soils, slope conditions, water velocity, rainfall intensity, and regulatory expectations.

4. Revisions

We refine the plan based on HOA input, municipal feedback, golf operations, or environmental requirements.

5. Implementation

Our team completes pipework, basin repairs, outfall restoration, grading, and stabilization using precise elevation control and durable materials.

6. Monitoring, Maintenance & Reporting

We provide long-term monitoring, catch basin schedules, and reporting to preserve system performance and compliance.
