The NDS Flo-Well dry well system is designed for drainage applications. Installation involves excavating a hole and surrounding the Flo-Well chamber with drain rock and soil. The amount of drain rock required is dependent on the dimensions of the excavated hole. Different hole sizes and depths will result in varying water holding capacities. Maintaining a minimum distance between Flo-Wells is also a key consideration during installation.
System Overview
The NDS Flo-Well system provides a method for managing water drainage. The system utilizes a chamber surrounded by gravel and covered with soil to temporarily store and slowly release water into the surrounding ground. The system’s capacity is directly related to the volume of drain rock and the space within the chamber itself. The documentation specifies dimensions for the surrounding rock and soil layers, as well as estimates for water retention.
Hole Excavation and Drain Rock Requirements
The amount of drain rock needed for installation is determined by the size and depth of the excavated hole. According to the provided documentation, a 4 ft. diameter hole that is 4 ft. deep requires a little less than 1.5 cubic yards of drain rock. A 3.5 ft. deep x 4 ft. diameter hole requires a little more than 1 yard of drain rock.
The documentation details specific rock layering requirements. For one installation configuration, approximately 11-1/4 in. of rock is placed below the Flo-Well chamber, with 1 ft. of rock surrounding it, and 8 in. of soil above. Another configuration specifies 6 in. of rock below, 1 ft. around, and 8 in. of soil above the Flo-Well dry well. These configurations impact the overall water holding capacity of the system.
Water Holding Capacity
The water holding capacity of the Flo-Well system varies based on the installation configuration. The installation with 11-1/4 in. of rock below the chamber, 1 ft. of rock surrounding it, and 8 in. of soil above is estimated to hold approximately 165.5 gallons of water. The alternative installation, with 6 in. of rock below, 1 ft. around, and 8 in. of soil above, is estimated to hold approximately 135.5 gallons of water. These figures represent the volume of water the system can temporarily contain before releasing it into the surrounding soil.
Spacing Between Flo-Wells
Proper spacing between individual Flo-Well units is crucial for effective operation. The documentation states that a minimum of 6 in. should be maintained between Flo-Wells. This spacing is necessary to facilitate adequate gravel fill around each unit and to provide structural support for the overall installation. Insufficient spacing may compromise the system’s ability to drain effectively and could potentially lead to structural instability.
Installation Considerations
Installation of the NDS Flo-Well system requires careful consideration of the surrounding environment and soil conditions. The documentation does not provide specific details regarding soil types or groundwater levels, but these factors would likely influence the overall performance of the system. Proper excavation and compaction of the surrounding soil are essential for ensuring long-term stability and preventing settling. The documentation also does not specify any particular tools required for installation.
System Components
The provided documentation does not detail the specific components of the Flo-Well system beyond the chamber itself and the surrounding drain rock and soil. It does not specify materials used in the construction of the chamber, nor does it provide information about any optional accessories or related products.
Maintenance
The documentation does not provide any information regarding the maintenance requirements of the NDS Flo-Well system. Regular inspection of the surrounding soil and drain rock may be necessary to ensure proper drainage and prevent clogging. The long-term durability of the system is not addressed in the provided materials.
Conclusion
The NDS Flo-Well dry well system offers a solution for managing water drainage. Successful installation requires careful attention to hole excavation, drain rock placement, and spacing between units. Water holding capacity varies depending on the installation configuration, with estimates ranging from 135.5 to 165.5 gallons. The provided documentation focuses primarily on installation parameters and does not address maintenance or long-term performance.
