Taylor Subdivision - Nashville, TN

Key Takeaways

• Three underground AquaCell detention systems provided over 44,000 ft³ of total storage while preserving developable land at the Taylor Subdivision site in Nashville, Tennessee.

• Modular AquaCell units allowed phased installation, with two systems installed in November 2024 and a third larger system installed in July 2025 to align with construction sequencing.

The Problem

The Taylor Subdivision development in Nashville, Tennessee required underground stormwater detention to satisfy local regulatory storage requirements while maintaining usable surface area for site improvements. During design coordination and shop drawing review, the engineer of record identified that additional detention volume was required across multiple system locations. The project also required systems capable of supporting traffic loading with shallow cover and accommodating phased construction as the subdivision was built out over time.

The Solution

Three AquaCell SC (standard configuration) underground detention systems were selected to meet the project’s storage and constructability requirements. Each system was designed with non-woven geotextile wrapping, perimeter stone, and a minimum three-inch foundation stone base placed on undisturbed native soil. The modular nature of the AquaCell system allowed the layouts to be revised to increase storage volume without increasing excavation depth or surface footprint.

System 1 provides approximately 8,310 ft³ of detention storage within a footprint of approximately 1,744 square feet. System 2 provides approximately 9,750 ft³ of storage within a footprint of approximately 1,550 square feet. System 3, the largest installation, provides approximately 26,613 ft³ of storage within a footprint of approximately 4,301 square feet. All systems were designed for traffic loading conditions up to HS-20 with standard minimum cover requirements.

The Impact

The AquaCell SC detention systems enabled the Taylor Subdivision project team to meet revised stormwater storage requirements while maintaining site flexibility and construction efficiency. The integrated design of the AquaCell units simplified installation by eliminating the need for manual assembly of individual structural components, reducing installation sensitivity and labor time compared to alternative modular systems. Phased installation allowed stormwater infrastructure to be constructed in alignment with development progress, supporting overall schedule management and long-term site performance. Wavin partners Integrated Technologies supported the project by facilitating system coordination and purchasing, while SRG Stormwater completed installation of all three detention systems.
