Keeping your Louisiana property dry can be quite challenging, but there are certain drainage systems that can make the task much easier. One of the most effective and sustainable solutions to manage excess water in your yard is the installation of a dry well. Whether you own a large property or a modest home and yard, dry wells are a low-maintenance option that can make issues caused by excess stormwater a thing of the past!
A dry well is a subsurface structure designed to manage stormwater runoff by collecting and gradually dispersing it into the surrounding soil. Essentially, it’s an underground reservoir that allows water to infiltrate the ground, reducing surface water accumulation and preventing flooding or erosion.
Dry wells are typically constructed from a large, perforated container made of plastic, concrete, or another durable material, surrounded by gravel or crushed stone. The gravel helps filter out debris and facilitates water absorption into the soil. When water from gutters, downspouts, or other drainage systems flows into the dry well, it gradually seeps into the ground, where it is absorbed, reducing runoff and the potential for standing water.
Dry wells and catch basins are both often used for managing stormwater on residential properties, but dry wells generally offer more benefits for homeowners. A dry well is particularly advantageous for homeowners because it requires minimal maintenance and helps recharge groundwater supplies. In contrast, a catch basin, which collects runoff and directs it to a drainage system or sewer, can be prone to clogging with debris and often necessitates regular cleaning to maintain functionality. Catch basins do not contribute to groundwater recharge and can lead to increased runoff to municipal systems, which may cause or exacerbate flooding issues in heavy rain.
The timing of dry well installation is crucial to ensuring its effectiveness. If you frequently notice areas of your yard where water pools after a rainstorm, this is a strong indicator that improved drainage is needed, and a dry well could be the solution. Similarly, if your property is experiencing soil erosion due to water runoff, installing a dry well can help control and redirect the water, protecting your landscape and nearby structures.
In regions with heavy or frequent rainfall, like Baton Rouge or Lafayette, the risk of flooding and water accumulation is higher, making a dry well an essential addition to your drainage system. If you plan to add new structures to your property, such as a patio, driveway, or garden shed, it's important to consider how these additions might affect water flow. Altering the natural flow of water may necessitate the installation of a dry well to prevent water from pooling in unwanted areas.
For properties that rely on septic systems, a dry well can serve as an overflow option during heavy rains, helping to prevent septic backups and protect your yard from potential contamination. During major landscaping projects that involve changes to the terrain, installing a dry well ensures that the new design includes adequate drainage, particularly in sloped areas where water runoff can be problematic.
Choosing the right location for your dry well is essential for its proper function. Ideally, a dry well should be installed in low-lying areas of your yard where water naturally tends to collect. These areas are more prone to water accumulation, and a dry well can provide significant benefits by managing this excess water. It is also important to place the dry well at least 10 to 15 feet away from your home’s foundation, septic system, or other structures to ensure that water is diverted far enough away to prevent damage.
The type of soil in the installation area is another critical factor. Dry wells work best in areas with permeable soil, such as sandy or loamy soils, which allow water to infiltrate easily. Conversely, installing a dry well in clay-heavy soils can impede water absorption and reduce the system's effectiveness. Keep the following list of areas and situations in mind when it comes time for you to decide where to install a dry well on your property.
Best Locations For Dry Wells
Dry wells can be part of a comprehensive drainage plan that includes other solutions like French drains and rain gardens. Consider integrating your dry well with these systems to manage water more effectively across your entire property, especially if stormwater has been a recurring issue. One of the most important things to keep in mind when installing a dry well is that the size of your dry well should be based on the amount of water you expect it to handle. This calculation involves understanding the drainage area (e.g., roof size or yard area) and the average rainfall in your region.
While installing a dry well can be a DIY project for those with some experience in landscaping or construction, we strongly recommend hiring a professional, especially for larger systems or more complex sites. Professionals like us can ensure proper installation, sizing, and connection to existing drainage systems. We can also check your system regularly to clear any debris from the inlet, check for clogs in the perforations, and ensure the gravel or stone layer remains intact.
