As urban landscapes grow, managing stormwater efficiently has become increasingly important. Underground stormwater facilities are an innovative solution to managing runoff while maximizing surface space. These systems not only help prevent flooding but also contribute to environmental protection. In this post, we’ll explore the different types of underground stormwater facilities and provide guidance on maintaining them effectively.

What Are Underground Stormwater Facilities?

Underground stormwater facilities are engineered systems designed to manage runoff from impervious surfaces like parking lots, roads, and rooftops. By storing or treating water below ground, these systems reduce the risk of flooding, protect water quality, and help properties meet regulatory requirements without sacrificing valuable land.

Types of Underground Stormwater Facilities

Underground Detention Facilities

These systems temporarily store runoff and release it slowly over time, reducing peak flow rates. They typically consist of large pipes, concrete vaults, or modular tanks and are ideal for controlling flooding in urban areas.

Underground Retention Facilities

Unlike detention facilities, retention systems are designed to permanently hold water, allowing it to infiltrate into the ground. This supports groundwater recharge and improves water quality by filtering pollutants naturally.

Sand Filters

Sand filters combine water storage with filtration. Stormwater passes through layers of sand or other media to remove pollutants before being released or infiltrated. These systems are particularly effective for treating runoff from industrial or commercial sites.

Proprietary Treatment Systems

These specialized systems are engineered to target specific pollutants, such as hydrocarbons, heavy metals, or nutrients. Examples include oil-water separators, vortex separators and the Contech StormFilter, which uses replaceable cartridges filled with filtration media like perlite, zeolite, or activated carbon. The modular nature of the StormFilter makes it adaptable to various site conditions, and its focus on pollutant removal makes it a reliable choice for protecting local waterways.

The Benefits of Underground Stormwater Facilities

• Efficient Land Use: By moving stormwater infrastructure below ground, properties can maintain usable space for parking, landscaping, or development.
• Flood Prevention: These systems control runoff during heavy rain, protecting downstream areas from flooding and erosion.
• Regulatory Compliance: Underground systems help properties meet stormwater management requirements imposed by local authorities.
• Environmental Protection: By controlling and treating runoff, these facilities help prevent pollutants from entering waterways.

Maintenance: A Key to Long-Term Performance

Regular maintenance is critical to ensuring the effectiveness and longevity of underground stormwater facilities. Each system type requires tailored care, but general practices include:

• Inspection: Periodically inspect the facility for sediment buildup, blockages, or structural issues. Inspections are especially important after major storms.
• Sediment and Debris Removal: Clear out accumulated materials to maintain the system’s capacity and prevent blockages.
• Cleaning and Repairs: Use hydro-jetting or vacuum equipment to clean pipes and chambers, and address any structural damage promptly.
• Compliance Documentation: Keep detailed records of maintenance activities to meet local regulatory requirements.

Detention ponds play a critical role in stormwater management, controlling runoff and preventing downstream flooding. Unlike retention ponds, which hold water permanently, detention ponds are designed to temporarily store stormwater, slowly releasing it to reduce the impact on local waterways. Regular detention pond maintenance is crucial for ensuring these systems function effectively, protecting property and the environment.

What Is a Detention Pond?

A detention pond, also known as a dry pond or stormwater basin, is typically dry except after rain events. Its purpose is to capture stormwater runoff during heavy rainfall, temporarily hold it, and release it slowly at a controlled rate through an outflow structure. This controlled release helps prevent flooding, soil erosion, and sediment buildup in nearby streams and rivers. Detention ponds are commonly used in commercial developments, industrial sites, and residential communities.

Why Detention Pond Maintenance Is Important

Effective detention pond maintenance is essential for keeping the pond’s drainage and outflow systems working as intended. Without regular maintenance, detention ponds can become clogged, reducing their capacity to manage stormwater. This can lead to issues like localized flooding, erosion, and sediment transport downstream, which can harm local waterways and create costly repairs.

Key Benefits of Detention Pond Maintenance

• Flood Prevention: Detention ponds mitigate flooding by temporarily storing and then slowly releasing stormwater, which helps protect surrounding property.
• Erosion Control: Properly maintained detention ponds help control the flow of stormwater, reducing soil erosion in surrounding areas.
• Water Quality Protection: Although they don’t permanently hold water, detention ponds help trap sediment and debris, preventing pollutants from entering natural water systems.
• Minimizes Long-Term Costs: Proactive maintenance helps avoid major repairs and replacements, ultimately saving property owners money.
• Supports Compliance with Environmental Laws: Regular maintenance ensures your detention pond adheres to state and local regulations, helping you avoid fines and legal complications.

Common Detention Pond Maintenance Challenges

Even well-designed detention ponds require ongoing maintenance to remain functional. Some common issues to watch for include:

1. Clogged Outflow Structures: Leaves, trash, and other debris can block the pond’s outlet, causing water to back up and potentially flood nearby areas. Regular inspection and cleaning are necessary to keep the outflow functioning.
2. Sediment Buildup: Over time, sediment from runoff accumulates at the bottom of the pond, reducing its capacity to hold water. Periodic sediment removal ensures the pond can handle heavy rain events.
3. Vegetation Overgrowth: Invasive plants and unchecked growth around the detention pond can obstruct water flow and increase erosion. Proper vegetation management helps maintain clear channels and protect pond structures.
4. Structural Wear and Tear: The pond’s structural components, such as embankments and spillways, are subject to wear from water pressure and weather. Regular maintenance and timely repairs help prevent costly structural failures.

How Often Should You Perform Detention Pond Maintenance?

The frequency of detention pond maintenance can vary depending on location, storm frequency, and local regulations. However, a few key maintenance tasks should be scheduled regularly:

• Inspections: Quarterly or biannual inspections are recommended to assess the pond’s condition. After significant rain events, an additional inspection should be conducted to identify any new issues.
• Sediment Removal: Sediment should be removed as needed, typically every one to three years, depending on the amount of runoff and debris. Accumulated sediment that reduces the pond’s depth by more than 25% should be cleared to restore full capacity.
• Outflow Maintenance: The outflow structure should be checked quarterly to ensure it is free of obstructions. Clogged outlets are a common cause of pond overflow and flooding.
• Vegetation Control: Regular mowing and removal of invasive plants around the pond edges prevent overgrowth that could block drainage paths and contribute to erosion.

Regulatory Compliance for Detention Ponds

In addition to maintenance, property owners are responsible for ensuring that their detention ponds comply with local and state regulations for stormwater detention. Many jurisdictions require periodic reports on pond maintenance, condition, and compliance with environmental standards.

Steps to Prepare Your Stormwater System for Winter

1. Clear Drains and Pipes

One of the most important steps in winter preparation is ensuring that drains and pipes are clear of debris. Leaves, sediment, and other materials can accumulate throughout fall, leading to blockages that freeze during cold temperatures. When ice forms in these blockages, it can cause pipes to burst, leading to costly repairs and potential flooding. Regularly cleaning and inspecting your system will help prevent this.

2. Inspect and Maintain Gutters and Downspouts

Gutters and downspouts are essential for directing water away from buildings. However, when they become clogged with debris, they can form ice dams. Ice dams prevent water from flowing properly, causing water to back up under roofs and leak into the building, leading to structural damage. By cleaning and inspecting your gutters and downspouts before winter, you can reduce the risk of ice dam formation and ensure your stormwater system operates effectively.

3. Monitor and Service Detention Basins

Stormwater detention basins play a vital role in managing runoff, especially during heavy rain and snowmelt events. During the winter, basins can freeze, reducing their capacity to handle stormwater. Inspecting your detention basins for debris and ensuring they are properly maintained will help prevent overflow and protect against flooding during spring thaw.

4. Maintain Erosion Control Measures

Erosion control is a year-round concern, but it becomes particularly important during the winter months when frozen ground can be susceptible to erosion during thaws. Implementing practices like hydroseeding, mulching, and installing erosion control blankets can help stabilize soil, reduce runoff, and protect your landscape from winter storm impacts.

5. Effective Snow and Ice Management

Heavy snow and ice buildup can block stormwater drains and pipes, leading to water accumulation and flooding. It’s important to manage snow carefully, ensuring that it’s removed from drainage areas and not piled in places where it can obstruct water flow. Additionally, you should be prepared for snowmelt in the spring, as excessive snow can create significant runoff that overwhelms stormwater systems if not properly managed.

The Benefits of Winter Stormwater Maintenance

Preparing your stormwater system for winter not only prevents damage but also extends the lifespan of your infrastructure. Regular maintenance ensures that your system operates efficiently year-round and reduces the need for costly repairs or replacements. Proactive winter maintenance also protects your property from flooding, minimizes erosion, and helps you remain compliant with local stormwater regulations.

Key Components of a Stormwater System

Stormwater management systems are designed to collect, store, and release rainwater in a controlled manner. Common components found in residential communities include:

• Retention and Detention Ponds: These are designed to hold excess runoff, allowing water to slowly infiltrate or release into surrounding areas.
• Storm Drains and Inlets: These structures collect runoff from streets and other hard surfaces and direct it into the stormwater system.
• Underground Storage Systems: Some properties have underground chambers that store excess stormwater, controlling the flow to prevent flooding.
• Bioswales and Rain Gardens: These are vegetated areas that absorb and filter runoff, improving water quality and reducing flood risk.

The HOA/COA’s Role in Stormwater System Maintenance

To ensure stormwater systems function effectively, HOAs and COAs must implement routine maintenance protocols. Proper upkeep not only helps avoid costly repairs but also ensures compliance with local and federal regulations. Here are some key responsibilities:

1. Regular Inspections

Routine inspections of stormwater systems are essential to catch potential issues early. HOAs and COAs should schedule professional inspections at least once a year, with more frequent checks after major storms. Inspectors will evaluate the system for:

• Sediment buildup in ponds or drainage areas
• Clogged storm drains or inlets
• Vegetation overgrowth in bioswales or rain gardens
• Signs of erosion or structural damage

2. Debris Removal

Storm drains and retention areas often accumulate debris, such as leaves, trash, and sediment, that can clog the system and cause flooding. HOAs and COAs should prioritize debris removal, especially after storms, to keep systems clear.

3. Vegetation Management

Maintaining the vegetation around detention ponds and bioswales is crucial for the system’s overall function. Overgrown or dead plants can obstruct water flow and reduce filtration efficiency. Regular trimming and replanting ensure the system works as designed.

4. Compliance with Regulations
