Above-Ground Facilities

Above-ground stormwater facilities are designed to hold and later release rainwater at ground level. Here are the types of above-ground facilities we inspect and maintain:

  • Stormwater Management Ponds: We offer preventive and corrective maintenance of stormwater ponds to keep them working effectively and efficiently for many years to come.
  • LID (Low-Impact Developments): By emphasizing maintenance and restoration, you can keep your LID facility looking great while reducing the risk of flooding.
  • Stormwater Bio-Retention Facilities: These systems help remove pollutants from stormwater runoff using plant materials and microbes. They provide an aesthetically pleasing stormwater solution—provided you keep up with regular inspections and maintenance.
  • Above-Ground Stormwater Management Sand Filters: These facilities are highly effective for treating runoff from impenetrable surfaces, such as parking lots. They require periodic inspections and maintenance to maximize performance and reliability.
  • Stormwater Infiltration Basins: Low-lying infiltration basins are excellent at preventing flooding, reducing downstream erosion, and improving the quality of nearby bodies of water. Our maintenance services ensure efficient, aesthetically pleasing operation.
  • Extended Detention Facilities: By holding excess rainwater after large storms, these facilities play a role in flood and erosion prevention. The effectiveness and code compliance of your extended detention facility depend greatly on the routine maintenance it receives.
  • Stormwater Services for a Notice of Violation: If you have been issued a Notice of Violation, trust iSTORMWATER to make the necessary repairs and corrections to your property.

Below-Ground Facilities

Below-ground stormwater facilities serve as an effective and practical way to reduce the quantity and improve the quality of stormwater runoff. Their underground location provides an efficient use of space, freeing up the land above for urban development. Here are the below-ground facilities we inspect and maintain:

  • CONTECH Engineered Solutions StormFilter: This stormwater treatment device traps particulates and absorbs pollutants from runoff. Routine maintenance is required to keep these filtration devices functioning as intended.
  • Hydro International Downstream Defender: This advanced hydrodynamic vortex separator captures and retains particles, oil, trash, and floatables from surface water runoff. While the device is a low-maintenance stormwater solution, it does require occasional inspections.
  • Underground Stormwater Detention Facilities: Whether your underground system is metal, concrete, or plastic, iSTORMWATER can deliver the necessary maintenance to keep it running optimally.
  • Aqua-Swirl Stormwater Treatment System: This custom-engineered water quality device removes coarse sediment, debris, and oil via hydrodynamic separation technology. Regular inspections and cleaning are recommended to remove captured contaminants from the system.
  • BaySaver Technologies: BaySaver solutions are designed to protect water resources every time it rains. Keep your device working properly with routine maintenance from iSTORMWATER.
  • Imbrium Stormwater Treatment Solutions: Imbrium offers numerous stormwater treatment products. No matter which system you have installed, our experts can clean and maintain them.

Real Results

iStormwater LLC was an excellent choice. They made the process of the Storm water pond repairs seamless. They took charge of the project and got the project approved and passing the inspection. We highly recommend them and would use them again.

Lyonswood HOA

Incredible stormwater management service. The owner John consulted on a property I manage and ended up saving us thousands of dollars in environmental fees from the government. Now, our property is compliant with the EPA and we have a great partner to keep us maintained on storm water regulations over time.
