What is Stormwater Runoff?
Stormwater refers to the water that originates from precipitation events such as rain or snowmelt. When it falls on impervious surfaces like rooftops, roads, and sidewalks, it cannot soak into the ground and instead becomes stormwater runoff. Stormwater runoff flows over these hard surfaces, eventually finding its way into drainage systems, streams, rivers, and lakes. Essentially, stormwater runoff is the excess water that does not get absorbed into the soil.
Why Should We Reduce Stormwater Runoff?
The consequences of excessive stormwater runoff can be detrimental to water quality and ecosystems. It can lead to increased pollution levels, degraded aquatic habitats, and the loss of native plant and animal species. By understanding the causes and impact of stormwater runoff, we can recognize the urgency in taking steps to reduce it.
How Does Rain Collection Help?
Rain collection techniques such as rain barrels and rain gardens play a vital role in mitigating stormwater runoff and reducing stormwater pollution. By intercepting and storing rainwater, these practices help decrease runoff volume and velocity, preventing street flooding and excessive flow into our stormwater systems and water bodies. Rain collection also filters the water, removing pollutants and contaminants before they enter the environment. By implementing rain collection methods, we can significantly reduce the amount of stormwater runoff and contribute to cleaner, healthier waterways.
How to Use Rain Barrels to Reduce Stormwater Runoff?
Rain barrels offer a simple yet effective way to harvest and utilize rainwater. By collecting and storing rainwater from rooftops, homeowners can reduce their reliance on municipal water supplies and save money on water bills. Additionally, rain barrels help to alleviate the strain on stormwater infrastructure and reduce the risk of localized street flooding. From an environmental standpoint, rain barrels contribute to water conservation by preserving a valuable resource and reducing the demand for energy-intensive water treatment processes. Read below for some quick tips on getting started with using rain barrels around your home.
Choosing the right rain barrel for your property: When selecting a rain barrel, consider factors such as capacity, durability, and aesthetics. Assess your water usage requirements, available space, and the intended use of the harvested rainwater. Look for barrels made from food-grade materials, designed with a secure lid to prevent mosquito breeding, and equipped with an overflow outlet for excess water during heavy rainfall. Additionally, explore options for connecting multiple rain barrels to increase storage capacity.
What to know when installing a rain barrel: Installing a rain barrel is a straightforward process that can be accomplished with basic tools and skills. Begin by selecting a suitable location near a downspout for optimal rainwater capture. Ensure the ground is level and stable to support the weight of a full rain barrel. Connect the barrel to the downspout using a diverter or by cutting the downspout and attaching a diverter kit. Position the barrel on a sturdy platform or secure it to a wall for stability. Finally, direct the overflow outlet away from the foundation of your home to prevent water damage.
Maintenance tips for maximizing rainwater collection: Regular maintenance is crucial for ensuring the efficient functioning of rain barrels. Inspect the barrel periodically for debris, leaves, and mosquito larvae, and clean it as necessary. Keep the lid securely closed to prevent contamination and reduce evaporation. Drain and store the rain barrel during winter to avoid freezing and potential damage. Additionally, consider using the harvested rainwater for activities such as watering plants, washing vehicles, or other non-potable uses to make the most of this valuable resource.
By embracing rain collection through rain barrels, property owners like you can make a significant impact in reducing stormwater runoff and protecting water quality.

How Much Runoff Does My Property Create?
Ever wonder how much stormwater runoff exists on your property? Understanding the amount of stormwater runoff generated by your property is an essential step in effective stormwater management. By gaining insight into this crucial information, you can make informed decisions on how to reduce runoff and minimize the impact from your property. To determine the runoff from your property, consider factors such as the size of your roof, the area of impervious surfaces like driveways and patios, and the slope of your land. You can also consult local stormwater management resources, contact your local municipality for guidance on calculating stormwater runoff, or use the EPA’s stormwater calculator tool. By learning about the specific amount of runoff generated, you can tailor your stormwater management strategies, such as rainwater harvesting or implementing permeable surfaces, to address the unique characteristics of your property and contribute to a more sustainable water future.

How to Use Rain Gardens to Absorb Runoff?
Rain gardens are beautiful, eco-friendly landscapes designed to capture and absorb rainwater. They provide a natural solution for managing stormwater runoff by allowing water to infiltrate into the soil instead of flowing into storm drains. Rain gardens offer numerous benefits, including reducing erosion, improving water quality, replenishing groundwater, and creating habitat for pollinators and wildlife. By implementing a rain garden, you can transform your outdoor space into a captivating oasis while contributing to the health of our waterways. Read below for some quick tips on planting rain gardens on the property around your home.
Selecting an appropriate location for your rain garden: Choosing the right location is essential for the success of your rain garden. Look for an area on your property where water naturally collects during rainfall or where downspouts direct water. Ensure the location receives at least 6 hours of sunlight per day and is a safe distance from your home's foundation. Consider the size and shape of the space available and any local regulations or guidelines for rain garden installations.
Design considerations and plant selection for optimal stormwater absorption: Designing a rain garden involves careful consideration of the soil, slope, and plant selection. The garden should be graded to create a shallow depression, allowing water to pool temporarily before gradually infiltrating the soil. Select native plants with deep root systems that can withstand both wet and dry periods. These plants will help absorb and filter the stormwater while providing aesthetic value. Group plants according to their water needs and consider incorporating layers of vegetation to maximize stormwater absorption.
Installation and maintenance guidelines for a thriving rain garden: Installing a rain garden requires proper preparation and construction techniques. Start by excavating the area, ensuring the depression is about 4-8 inches deep. Amend the soil with organic matter to improve drainage and create a healthy growing environment for plants. Mulch the garden to reduce weed growth and retain moisture. After planting, water the garden regularly until plants are established. Ongoing maintenance includes regular watering during dry spells, removing weeds, and occasional pruning. Don’t forget to regularly check the garden for sediment buildup and ensure the drainage area is clear to prevent blockages.
