DRAINAGE DESIGN CASE STUDY:

As part of the infrastructure upgrades at Orlando International Airport’s Terminal C, a targeted drainage enhancement project was completed along the 11400 Terminal C Service Road. The scope involved extending weep holes through proposed reinforced concrete barriers to improve water drainage performance and long-term reliability of the site’s stormwater channel and retaining wall systems.

JET Filter System supplied corrosion-resistant, maintainable drainage components to prevent hydrostatic pressure buildup and structural deterioration.

Florida’s subtropical climate results in frequent heavy rains, often leading to water pressure buildup behind concrete walls and stormwater channels. Without proper drainage systems, structures such as retaining walls and concrete barriers are vulnerable to:

• Soil loss

• Hydrostatic pressure-induced cracking

• Compromised structural integrity

This made a long-lasting, maintainable drainage solution essential for the Terminal C Service Road retaining wall.

In collaboration with AECOM and The Middlesex Company, the project team installed:

✅4” open-end diameter, ASTM 316/316L Stainless Steel

✅Geotextile Filter Media: Mirafi® Filter-weave FW 300

✅Integrated through reinforced concrete barriers

These drains offer controlled water release, sediment filtration, and future accessibility for inspection and maintenance—ensuring long-term drainage efficiency beneath Orlando’s busiest travel hub.

Airport infrastructure must be able to manage massive runoff volumes due to:

• Heavy rainfall

• Pavement slope accumulation

• Frequent surface loading near runways and service roads

Installing maintainable weep hole drains in concrete structures ensures:

• Long-term water pressure relief

• Protection against wall deflection or erosion

• Reduced maintenance costs

• DOT-compliant and accessible solutions
