Stormwater Retention Basins St. Louis Missouri

Stormwater runoff can include contaminants that may need to be filtered before it goes into the ground and can cause a variety of issues like foundation problems or erosion. Proper control of stormwater runoff can provide the solution needed to prevent these and other issues. Learn more about how to control and filter the stormwater on any property through altering the direction, detention and retention basins, dry detention and filtering.

What is Bioretention?

Bioretention is a method of controlling and filtering stormwater. The goal is to remove contaminants before the stormwater enters the native soils. Or is moved to stormwater drains, ponds, creeks, and other bodies of water. Bioretention involves directing the water to specific basins designed to help filter the water, then direct the water where it needs to go next. Though this can help in any area where it rains a lot, it is especially helpful in areas that experience flooding regularly. As it can help direct and move the water to prevent the flooding.

Retaining Storm Water – How It’s Done

For stormwater flood control, dispersing water at a controlled rate and filtering, there are a few basic steps to take. These steps include the following.

  • Directing the Water – The water on the property will need to be directed to a detention basin, retention basin, dry basin or drainage pond on the property. This can be done using a variety of methods, from proper drainage piping to creating swales that help direct the water naturally or using a catch basin drain. The right solution depends on the amount of stormwater being moved and the layout of the property.
  • Retention Basins or Retention Ponds – The water will be moved to a detention pond or basin. This is basically a low-lying area on the property that has the ability to filter the water and remove any contaminants before the water is used elsewhere. Most property owners use natural ways to filter the water, as this provides a more natural appearance on the property.
  • Filtering the Water – As the water flows into the basin, it goes through various natural filtering options. Some of the ways to filter the water include through a strip of grass that can remove solids, aquatic vegetation that can help remove excess nutrients, mulch, and sand. The basin may include an underdrain system that can help move the excess water further once it is treated.
  • Moving the Water – These basins are generally shallow, so they will have an underdrain system or a way for the overflow to move elsewhere on the property. Typically, once the water is filtered, it’s allowed to naturally drain into the soil or is moved to a storm drain system.

Stabilization and Control

Retention basins and ponds move a lot of water, especially in areas that are prone to flooding or that experience a significant amount of rain throughout the year. These ponds are a great way to handle the water, but they can have stabilization issues, especially over time. To help with this, there are numerous options available, depending on the issue and the property.

  • Stabilizing Pond Edges – Pond edges can suffer from erosion over time, especially if the water levels vary significantly throughout the year. The installation of rip rap rocks can help prevent this by stabilizing the pond edges so that erosion is less likely to occur. This is done through careful preparation and then the installation of the rock.
  • Restoration of Creek Beds – Creek beds can collapse if there is a significant amount of water flowing through them. Erosion can occur quickly when there is flooding or over time. When this happens, there are a variety of solutions available to restore the creek bed and help prevent erosion from occurring in the future. Rip rap rocks are one solution that can be used here, as well, with great success.
  • Pond Stabilization – The edges of ponds and rivers are at risk of erosion due to the water, especially at inlets to ponds or where the water flows quickly through a river. Stormwater ponds have water levels that are constantly changing, so they can be at more of a risk for erosion, but there are ways to stabilize it. Adding rocks and other materials around the pond, for example, can help prevent future erosion. 

Finding the Right Stormwater Basin Solutions

When flooding or large amounts of stormwater are a concern, a retention basin may be a fantastic option to handle the water and prevent damage to the landscaping. However, there are many options available, and it may be difficult to determine the right one for the property. Speak with an expert who can take a look at the property, discuss design ideas, and provide an effective but attractive option for handling stormwater and flooding.

Stormwater basins are an effective method for bioretention and can be beneficial for any property that experiences flooding or severe storms throughout the year. Our team can help you determine the right solution for your property, no matter the size or the concerns you may have. Contact us today to learn more about how we can help with stabilization, stormwater basin construction, bioretention maintenance programs and more.

Stormwater Basin Solutions

Bioretention Basins

Bioretention – is the process of filtering sedimentation and contaminants from stormwater runoff through the use of landscaped depressions or shallow basins. These bioretention basins are created to slow and treat on-site stormwater runoff during and after a rain event as water accumulates in the area. These basins are installed at points where stormwater is directed. The water then percolates through the system and the biological process treats the water before allowing any overflow water to flow into the municipal stormwater sewer system.

We professionally install and renovate Bioretention Systems.


Bioswales – are landscaped features with the primary purpose of filtering stormwater through a combination of special soils, vegetation and rock. Filtering the rain water helps remove pollutants, silt and debris along with slowing down and minimizing the waterflow into the storm sewer system. While the water accumulates, it also benefits the surrounding area by allowing for groundwater recharge in the area of the bioswale.

Contact us today if you need a bioswale constructed or renovated back to “as-built” specifications.

Retention Basins & Ponds

Retention basins – or retention ponds are often referred to as a “wet ponds”, a “wet detention basin” or “stormwater management pond”. Moreover, retention basins are used to manage stormwater runoff which helps to prevent flooding, downstream erosion, and improve water quality that’s flowing from the basin to an adjacent river, stream, or lake. Wet ponds are commonly created for water quality improvement, groundwater recharge, flood protection, and aesthetic improvement designed to improve the neighborhood or office park.

Contact us today to discuss retention basin erosion, pond dredging and overflow system repair and management.   

Pond Edge Stabilization

Shorelines of stormwater ponds are prone to erosion due to the many forces that work to undermine the stability of the banks and edges. Subtlest is the most significant erosional force at the shoreline which is caused by the ongoing water ripples that loosen saturated soils and constantly pulls soil particles apart directly below the water surface.

Stormwater ponds are even more susceptible to this due to the rising and lowering of water levels that occur through each rain event. The repeated rise and fall of water levels create currents that actually pull soil away from the banks. In addition to these naturally occurring erosion impacts, storm sewer discharge pipes, swale discharge, and downspout pipes that drain to the pond can also have a major impact on erosion and can cause deep gullies and holes in the ponds banks.

Reach out to our team today for a pond edge stabilization project consultation. We are ready to clean up and stabilize your stormwater pond! 

Pond & Lake Dredging Services

We offer hydraulic dredging services – to remove sediment buildup and restore the stormwater basin capacity to as-built design. This is the least invasive dredging process for HOA communities and for the wildlife within the existing pond ecosystems. 

The end results are; basin depths to original as-built levels, zero-impact to wildlife during the dredging process, the beauty of your pond restored, and minimal disturbance to your existing landscape.

Trash Rack Installation

We install custom debris grates – to help filter your inflow pipes or outflow pipes of debris. This will maximize flow and allow your stormwater basin to function as designed.

These grates are designed specifically for Drainage Team to assist in the prevention of floating and submerged debris before entering stormwater and waste water systems while maintaining designed water flow. Applications include drain grate inlets, stormwater detention facilities, dams, wastewater treatment and industrial facilities. Custom trash racks may be fabricated to meet project-specific requirements.

Creek Restoration

Drainage Team executes – best-practice creek restoration techniques that are innovative, support a healthy creek / river ecosystem and wherever possible we work with natural processes.

Most creek restoration projects include cleaning up the creek area, re-establishing the water flow channel, establishing new vegetation on the creek banks along with rip rap rock installation to stabilize the toe of the slopes into the creek.

We follow up with the necessary aftercare to ensure plant success and maintenance programs to keep your creek looking / functioning great year after year.
