St. Louis Stormwater Basin Design, Restoration & Maintenance
Stormwater can be powerful and destructive. Uncontrolled runoff leads to flooding, foundation damage, and erosion that compromise the integrity of your property. Drainage Team designs and installs engineered stormwater basin systems that manage flow, filter contaminants, and protect your land and structures for decades.
With decades of stormwater management expertise, our team creates custom detention, retention, and bioretention basins designed to slow, clean, and safely redirect runoff. We also renovate and restore existing stormwater basins to bring them back into full compliance with local sewer district regulations, reducing maintenance and restoration cycles to preserve budgets while improving performance, stability, and long-term functionality.
Each basin is built for stability, function, and longevity. We reinforce pond edges, repair erosion, restore creek banks, and integrate stormwater basins with your property’s existing drainage systems. Using Schedule 35 PVC and Severe Duty ADS N12 Dual Wall Piping, we ensure maximum flow capacity, structural strength, and reliable long-term performance.
Properly designed stormwater basins protect foundations, roads, and communities by keeping runoff where it belongs and keeping contaminants out of native soils and waterways. Whether your property needs a new bioretention system, basin repair, or stabilization, Drainage Team delivers guaranteed solutions that combine engineering precision with lasting environmental benefit.

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
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.
Our Stormwater Basin Process & Best Practices
Stormwater Pond Project Management
We have systems in place to manage our relationship with you from your first contact with us all the way through post-project review. We have designated stormwater basin project consultants, production managers, quality control measures, designated crews and specialized equipment to complete any sized stormwater basin project.
Vendor Relationships
Our company maintains vendor relationships like we do with our ongoing clients. This ensures our company and our clients the best, up-to-date materials, installation technologies & techniques, pricing, equipment and timeliness of stormwater basin project material sourcing.
On-Site Stormwater Basin Consultation
The first step in getting your project completed by us is to meet on-site at your property to discuss your stormwater basin issues and your goals in solving them. Next, one of our project consultants creates a comprehensive written project proposal & plan to solve them once and for all. We can create a drawing, but there are engineering fees associated with these types of plans.
Basin Project Scheduling
Once your project is accepted, it goes into our production department and placed on our workflow schedule. Depending on the time of year, your stormwater basin project will be scheduled between 2 weeks – 16 weeks out from the day we received your accepted Project Order Form.
Stormwater Basin and Bioretention annual maintenance programs are performed 12 months a year and are set up on an annual maintenance agreements. Maintenance services typically start within 2-4 weeks of receiving your signed service agreement.
Our Crews
Once we have come up with a stormwater basin project plan and agreement, our crew arrives to implement the solution we proposed. Our stormwater basin crews have decades of experience and are equipped with tools similar to a grading and excavation company. We execute the project as proposed.
Precision Completion of Projects
Our crews have all of the necessary tools and equipment to ensure your project is a success. We shoot the grade with transits and use depth measuring technology during stormwater basin projects. Any excavation of trenches are compacted with heavy duty, specialized compaction equipment… so there’s no settling once we’re finished with your project. Access points / material staging areas are organized, secured, minimized and restored once project is complete.
Professional Stormwater Basin Techniques, Maximized
When installing our stormwater basin solutions, we implement the absolute best techniques. Our focus is longevity of our project installation, minimizing erosion while filtering silt, simplifying future maintenance requirements and extending required maintenance intervals.
