Techniques & Best Practices for Stormwater Management

Stormwater runoff is one of the leading causes of water pollution in the U.S. Knowing how to effectively manage runoff is essential for protecting the environment and local infrastructure. Runoff can collect pollutants such as oil, chemicals, and debris, which then can contaminate waterways. Implementing the right stormwater management systems helps to improve water quality and ensure compliance with local and federal rules and regulations.

How Stormwater Management Works

In the United States, stormwater is one of the biggest threats to water quality, according to the Environmental Protection Agency (EPA). When rain falls on surfaces like roads, rooftops, and parking lots, it can’t soak into the ground. Instead, it flows toward storm drains, ditches, and downspouts, carrying pollutants like chemicals, oils, trash, pet waste, fertilizers, and more into local waterways. Stormwater management is the process of using systems to control and reduce flooding, erosion, and water pollution. 

The best way to manage stormwater runoff is to use tools and methods that control the amount and speed of runoff while improving water quality. These are known as best management practices (BMPs). When deciding which BMPs to utilize, there are factors to take into consideration, such as stormwater objectives (water quality standards, regulations), location-specific characteristics (soil composition, land slope), surrounding land, and development goals.

These practices slow down and remove contaminants from runoff before it reaches rivers, lakes, and oceans. One example of a BMP is stormwater runoff management systems, which help maintain water quality while protecting the environment by preventing water pollution. Practicing proper stormwater management techniques is also important for ensuring you meet local regulations and ordinances.


Different Stormwater Management Techniques

Effective stormwater management involves a combination of three techniques that can improve water quality and reduce runoff. These techniques are green infrastructure, structural BMPs, and non-structural BMPs. Using these three stormwater management strategies collectively creates a strong and effective overall strategy.

Green Infrastructure Solutions

Green infrastructure (GI) is a natural and sustainable approach to stormwater mitigation. It uses natural systems such as trees, soils, and vegetation to absorb and slow down runoff. Trees intercept rain as it falls from the sky, and soil acts as a sponge, absorbing the water and filtering the pollutants from various waterways. Vegetation such as native plants and green roofs reduce runoff and improve air quality.

Structural Best Management Practices (BMPs)

Structural BMPs are systems and tools that collect, control, and treat stormwater runoff. These BMPs can be large-scale, such as retention ponds and detention basins, but can also be smaller products that are used in day-to-day stormwater control. Pipe socks, dewatering bags, drain guards, curb and gutter guards, silt dikes, and other water management tools are commonly used. These products are essential for filtering sediment and pollutants, preventing the debris from entering storm drains. These tools help ensure higher water quality. They also make sure local environmental rules are followed, whether used for a short time or a long time.

Non-Structural Strategies

Non-structural BMPs are stormwater management practices and strategies that focus on policy, planning, and education aimed at reducing the pollution of stormwater runoff. They influence and impact physical outcomes. Some non-structural stormwater management examples include zoning laws, site design, public awareness campaigns, maintenance programs, green space requirements, and more. They play an essential role in creating change and facilitating physical implementation. They lead to and are used alongside green infrastructure and structural solutions.


The Need for Stormwater Management Systems

Stormwater management systems are critical for preserving ecosystems, protecting public health, and ensuring safe and sustainable development. Without these systems, communities face higher risks of water contamination, property damage, and infrastructure repairs. As new developments are created and urban areas expand, natural landscapes become replaced with pavement and hard surfaces that are impermeable. This can lead to increased runoff, which can overwhelm drainage systems, cause flooding, and lead to poor water quality.

Cost-Efficient Considerations of Stormwater Management

Investing in stormwater management systems provides long-term financial and environmental benefits. These systems help to prevent flood damage, avoiding costly repairs for homeowners and municipalities. Filtering pollutants before they reach waterways ultimately lowers operational costs for municipal water treatment facilities.

Green infrastructure has another benefit – it can enhance property value and aesthetic, making neighborhoods more welcoming and desirable. Staying compliant with local and federal regulations also helps in avoiding fines and legal issues. Overall, stormwater management systems contribute to healthier communities and ecosystems.


Best Practices to Manage Stormwater Runoff

To manage stormwater runoff effectively, experts suggest the following best practices:

  • When possible, use permeable materials in place of pavement so that water can be absorbed.

  • Use trees, vegetation, native plant species, and green roofs where possible to naturally absorb water.

  • Place rain barrels or liquid storage tanks in locations where they can collect roof runoff for use in gardens.

  • Clean storm drains and gutters regularly to prevent any blockages or overflowing.

  • Promote awareness and education about stormwater and what can be done to reduce pollution.

It is always a good idea to have stormwater management systems and tools handy for everyday use and any unexpected events. This way, you can stay prepared in case of an emergency. By combining these three techniques, healthier environments can be made possible.
