NDS FWAS24 50 Gal Flo Stormwater Dry Well System Kit – 3 Side Panels & 1 Cover (Black)

Smart underground drainage that detains and infiltrates excess water

Rain and irrigation can overwhelm landscape areas, leading to standing water, soggy lawns, and erosion. The NDS Flo-Well Dry Well System (FWAS24) sits underground to capture runoff and release it gradually into the soil. The gravel-free interior provides more detention volume than traditional gravel-filled wells, helping reduce surface ponding without bulky fill.

Water collected upstream with a catch basin or channel drain is carried by pipes into the dry well, then seeps out through the open bottom and weep holes as needed. For local stormwater detention and infiltration, the Flo-Well Dry Well System works as a standalone solution or as part of a larger setup. It also pairs well with rain gardens and bioswales to manage flow and absorption from impervious surfaces.

Notable benefits at a glance

• Gravel-free interior offers up to 250% more detention volume than comparable gravel-filled wells.
• Top access and knockout points enable simple pipe connections to 4-inch sewer and drain systems; 12 side-panel knockout points support multiple routing options.
• Underground installation allows burial up to 8 ft deep and supports pedestrian traffic, including lawn tractors.
• Use one dry well or multiple; units can be stacked up to 4 high or spaced 18" apart for scalable drainage in yards, playgrounds, golf courses, wash-down areas, rain gardens, and bioswales.
• Open bottom and weep holes promote infiltration into the ground, aligning with natural drainage processes.

Real-world use in everyday spaces

In residential settings, the Flo-Well helps manage yard drainage near driveways or garden beds, reducing surface ponding after storms. In commercial or public spaces, it offers flexible configurations for larger sites like parks, campuses, or sports facilities where runoff is a concern. The kit includes three side panels and a top cover, with a bottom panel available separately if a sump pump base is needed.

Installation and versatility

Connect to 4-inch sewer and drain piping via the top cover knockout, then use the 12 side-panel knockout points to route water where needed. The unit can be buried or stacked, up to 8 feet deep, and is designed to endure pedestrian use. It functions well as a standalone unit or as part of a multi-unit arrangement, enabling scalable drainage for diverse spaces.

Designed to blend with landscapes and provide a maintenance-friendly option, the FWAS24 kit ships unassembled with a top cover and three side panels, making on-site assembly straightforward for capable DIYers or professionals. The system’s gravel-free interior reduces heavy material handling while delivering robust performance across seasons.
