NDS Inc. has announced the launch of its Stormwater Drainage Tools mobile app. Designed for contractors, civil engineers, landscape architects, and DIY homeowners, the Stormwater Drainage Tools app calculates storm water runoff and determines requirements for implementing a variety of drainage solutions.
The app includes NDS’ complete product catalogs for drainage, storm water management, irrigation and flow management. It features a calculator that determines runoff in gallons per minute and cubic feet of water per second as well as required pipe diameter for any given drainage need. It also includes a separate calculator for determining the number of dry wells needed for detaining collected stormwater and the type and size of drainage pipe needed based on area size and surface type, the depth and thickness of gravel backfill, and the slope of drainage pipe. The app also links to Where to Buy information for purchasing products.
The human health costs of poor drainage on a property can be significant:
- Poorly drained runoff from roofs can enter basements or flow inside homes through foundational cracks or leaks where it can warp floorboards and turn finished rooms into messes that can attract insects and rodents
- Outside, inadequate or non-existent drainage from gutter downspouts can also create standing water that can harbor breeding spots for mosquitoes that carry West Nile virus, Zika virus and heartworms
The financial costs of poor drainage can be substantial:
- Drying a basement of toxic water due to poor drainage ranges from $1,000-$10,000, according to the U.S. National Flood Insurance Program
- Repairing damage to a home’s foundation as a result of poor drainage can range from $3,500 to $25,000, according to the National Association of Realtors
- Replacing a landscape washed away from heavy rains averages $7,500 and can run as high as $30,000, according to HomeAdvisor
- Soggy, poorly graded ground spells certain doom for lawns, shrubs and plants, and current estimates are that a home with a major drainage problem or foundation damage can reduce a home’s value by 10-15 percent, according to the National Association of Realtors
Two solutions for drainage problems are French drains and dry wells.
A French drain is a trench filled with gravel, rock or a gravel-free alternative containing a perforated pipe that directs storm water away from a specific area, blocks the passage of excess debris, and collects water over the entire length of the drain instead of one particular spot. NDS offers two French drain products, called EZflow and EZ-Drain, that are all-in-one gravel-free alternatives to a traditional French drain. EZflow is available in 5-foot lengths; EZ-Drain is available in 10-foot lengths. Both products feature a slotted pipe surrounded by a polystyrene aggregate enclosed in a geotextile mesh. The aggregate increases void space for improved water flow and storage while offering more structural integrity than gravel. Both products are ideal for retaining walls, foundation and footing perimeter drains, landscape drains, and sports fields.
Dry wells capture, filter and discharge storm water into the subsoil, reducing pollutants, helping replenish groundwater tables, and managing storm water close to its source. Used independently or as part of a larger storm water management system, dry well units can meet a variety of project needs and accommodate higher volumes of water. NDS offers a dry well product, called Flo-Well, that holds up to 50 gallons of storm water per unit and is a gravel-free alternative to a traditional dry well without requiring heavy equipment for installation, saving time and labor. Flo-Well is a 2-foot round barrel made of 100 percent recycled plastic materials that is assembled and placed into a hole. A lid is then placed on the Flo-Well to prevent dirt from getting inside. The side panels have knockouts that remove to allow for a variety of pipes to be connected.
The NDS mobile app is available for download at the Apple App Store and Google Play.
