Fort Leonard Wood Military Facility Engineered Stormwater Trench Drain System Supporting U.S. Army Infrastructure
Stormwater management is a critical component of infrastructure design for military facilities, where operational reliability, safety, and long-term durability are essential. At Fort Leonard Wood, engineers were tasked with implementing a drainage system capable of efficiently managing stormwater runoff around a large operational building while maintaining the structural strength required for heavy-duty environments.
Military infrastructure must perform under demanding conditions. Facilities experience high traffic loads, large paved areas, and significant runoff during storm events. Without properly engineered drainage systems, stormwater can accumulate along building perimeters and paved surfaces, leading to water pooling, pavement deterioration, and increased maintenance requirements.
To ensure the drainage system was properly engineered from the earliest stages of the project, Kirk Cameron, a civil engineer responsible for infrastructure design at the installation, reached out to the Swiftdrain engineering team during the early planning phase of the project.
By collaborating early in the design process, the engineering teams were able to develop a trench drainage solution tailored specifically to the site’s hydraulic requirements, grading conditions, and operational demands. Early engineering coordination ensured that the trench drain configuration would be optimized before construction began, helping eliminate potential design conflicts during installation.
The result was a custom engineered heavy-duty trench drain system designed to provide efficient stormwater capture and conveyance while supporting the demanding infrastructure requirements typical of military installations.
For engineers unfamiliar with linear drainage systems, a trench drain is a surface drainage system designed to intercept runoff along a continuous channel and convey water to an outlet. To learn more about these systems, see our guide explaining what a trench drain is and how it works.
Project Overview
Project Location Fort Leonard Wood, Missouri
Application Stormwater management around a large operational building
System Length 153+ Linear Feet
Total Channel Sections 46 Complete Channel Units
Drainage Outlet 8-inch stormwater pipe connection
Grate Type Class E ductile iron grates
Channel Type Heavy-duty precast concrete trench drain channels
System Configuration Combination of pre-sloped channels and neutral channels
Engineering the Drainage Challenge
Large facilities often experience concentrated stormwater runoff along building perimeters, access drives, and paved surfaces. During heavy rainfall events, water can flow across large paved areas and accumulate at low points around structures.
Without an engineered drainage system designed to intercept and convey this runoff, stormwater accumulation can lead to:
• Surface water pooling • Pavement deterioration • Freeze-thaw damage in colder climates • Safety hazards for vehicles and personnel • Increased maintenance costs over time
For military infrastructure, these issues must be addressed with drainage systems capable of delivering high hydraulic capacity while maintaining exceptional structural durability.
The engineering team at Fort Leonard Wood required a drainage system capable of capturing stormwater runoff along a large paved area and directing it efficiently into the facility’s stormwater infrastructure.
Because the drainage system would be installed in a heavy-use area, the system also needed to support high load conditions and long-term operational reliability. These requirements made heavy-duty trench drain systems an ideal solution for the project.
Engineers often evaluate trench drain systems based on load ratings, which determine how much weight the system can safely support. To understand how trench drain load classifications work, see our guide to trench drain load ratings.
Swiftdrain Engineering Solution
Working closely with the Army engineering team, Swiftdrain helped design a heavy-duty trench drain system utilizing 12-inch wide precast concrete trench drain channels paired with Class E ductile iron grates.
This system was selected for its ability to provide:
• High stormwater capture capacity • Exceptional structural strength • Long service life in demanding environments • Efficient installation for large infrastructure projects
Heavy-duty trench drain systems are commonly used in applications such as industrial facilities, airports, transportation terminals, and military bases. To explore the full range of available systems, visit our trench drain systems overview.
A key aspect of the system design at Fort Leonard Wood was the use of a combination of pre-sloped trench drain channels and neutral channels.
Pre-sloped trench drain channels incorporate an engineered internal slope that allows water to flow efficiently through the system using gravity. These channels eliminate the need to rely solely on the surrounding pavement slope and help maintain consistent hydraulic performance throughout the trench drain system.
Neutral channels were incorporated strategically within the system layout to ensure the trench drain configuration aligned precisely with the project’s site elevations and outlet location.
This balanced configuration allowed the drainage system to achieve optimal hydraulic efficiency while maintaining flexibility during installation.
Engineers designing trench drain systems must also consider hydraulic capacity and flow characteristics. Our engineering resource on flow rates and trench drain slope design explains how channel slope impacts drainage performance.
System Layout and Configuration
The completed installation consists of a continuous trench drain run exceeding 153 linear feet, made up of 46 complete trench drain channel sections.
Stormwater captured along the trench drain flows through the internal channel system before being conveyed into an 8-inch stormwater pipe, which transports the water into the site’s stormwater infrastructure.
This linear drainage configuration allows runoff to be captured along the entire length of the trench drain, preventing water from accumulating along the building perimeter or surrounding pavement surfaces.
The trench drain system was installed flush with the pavement surface, ensuring smooth integration with the surrounding infrastructure while maintaining full drainage functionality.
Proper installation is critical to ensure trench drain systems perform as designed. For contractors and engineers interested in installation best practices, see our detailed trench drain installation guide.
Engineering Collaboration
One of the most important aspects of the Fort Leonard Wood project was the close collaboration between the Army’s civil engineering team and Swiftdrain’s design specialists.
By working together during the early stages of the project, the engineering teams were able to determine the precise combination of pre-sloped channels and neutral channels required for the site conditions.
According to Cameron, this collaboration helped ensure that the trench drain system was configured correctly before installation began.
He indicated that he was extremely pleased with the outcome of the project, expressing appreciation for Swiftdrain’s dedication throughout the design process.
Cameron specifically noted that Swiftdrain worked closely with the project team to ensure the system included the proper number of neutral channels and pre-sloped channels, allowing the trench drain configuration to match the site’s grading conditions perfectly.
This level of engineering coordination is particularly valuable for infrastructure projects where even small adjustments in channel configuration can significantly impact long-term drainage performance.
Coordination with Distribution and Contractor Teams
In addition to engineering design support, Swiftdrain worked closely with the project’s supply chain partners and contractor team to ensure the drainage system was delivered and installed successfully.
The Swiftdrain team coordinated with the local distributor responsible for supplying the trench drain components, ensuring that materials were delivered according to the project’s schedule and specifications.
Swiftdrain also provided technical assistance to the installation contractor, Shulty Contracting, helping ensure that the trench drain system was installed correctly and efficiently.
This coordination helped ensure that all parties involved in the project had the support needed to complete the installation successfully.
