Exact Stormwater Management

An underground detention system is designed to manage stormwater runoff in areas with mostly impervious surfaces. Because the system is underground, there will be more space above ground that can be used for building and development. Instead of letting rainwater rush off into the streets, these systems store and control its flow.

These underground chambers are most often installed beneath parking lots or green spaces. When it rains, stormwater is directed into the underground detention system and stored there. Once the rain intensity decreases, the stored water is released gradually. This controlled release helps prevent flooding downstream and minimizes erosion. This also mitigates flooding and helps maintain a stable water flow in nearby rivers and streams.

This system can be designed and built using any number of various products, such as R-Tank, StormTech, Cultec, pipe, among others. However, what the system is meant to do, and the general method remains the same across all underground detention systems.

In many urban development projects, space is limited. Underground detention systems allow for efficient stormwater management without sacrificing surface area. Large commercial developments, like shopping centers or business parks, can create substantial amounts of impervious surfaces. Underground detention systems are a smart choice in these busy areas.

As we continue to innovate in stormwater management, underground detention systems play a vital role in safeguarding our urban spaces.

Where there is an underground detention system, there are a few signs you should be on the lookout for that may indicate that the system needs a professional inspection and, potentially, maintenance.

If you notice persistent pooling water around the detention area, it could suggest a problem with the system's drainage or outlet. Visible signs of soil erosion or settlement around the detention system may indicate structural issues that need attention. Inspect the visible surfaces of the detention structure for any cracks, damage, or signs of wear. This could be indicative of structural issues. Excessive weed or plant growth in and around the detention area might suggest neglected maintenance.

Detecting unpleasant odors in the vicinity may indicate stagnant water or the presence of pollutants, signaling a need for inspection. Visible debris, trash, or litter around the inlet and outlet points may obstruct water flow, prompting the need for cleaning and inspection. Ensure that safety features, such as access hatches and grates, are in good condition. Damaged or missing safety features can pose risks.

Noticeable changes in the surrounding landscape, such as new construction or alterations, may warrant an inspection to assess potential impacts on the detention system. Stay informed about local stormwater management regulations. If there are new regulations or changes, it might be a good time to schedule an inspection to ensure compliance. Review any available maintenance records. If it's been a while since the last inspection or if there are documented issues, it may be time for another assessment.

If you observe any of these surface-level signs, it's advisable to consult with a qualified stormwater management professional. They can conduct a thorough inspection, identify potential issues, and recommend appropriate actions to ensure the proper functioning of the underground detention system. Regular inspections are crucial for preventing larger problems and maintaining effective stormwater management.

If you haven’t done an inspection, our team of licensed professionals can do one for you. If you’ve already had an inspection of your system and found problems, we can help resolve any issues that have been documented. Exact will perform a thorough forensic investigation to help determine problems and their root causes, and we’ll help create a plan to remedy the problem. We can help maintain all underground detention systems, including R-Tank, RainTank, StormTech, Cultec, and pipe systems from any brand your system may be using.

Installation of an underground detention system begins with an excavation of the land in the designated area according to the design specifications. Then, filter fabric is placed along the sides and bottom of the trench to prevent soil erosion and enhance filtration within the detention system.

Inlet structures are installed to direct stormwater runoff into the detention system and outlet structures for controlled discharge. The underground detention units are assembled according to the design, ensuring proper alignment and connection between units. Finally, the area surrounding the detention system is backfilled with suitable materials, usually stone, compacting each layer to provide stability and support.

Connect the detention system to the existing stormwater management infrastructure, ensuring proper flow and functionality.
