Commercial Client: Metropolitan Atlanta Rapid Transit Authority(MARTA) Lakewood/Ft.Stewart Station Atlanta, Georgia Challenge Harvest water from train stations to supply water for irrigation plant material onsite. Application Prefiltered with WFF 150 Wisy filters 3,100 gallon storage tanks Benefits Promote environmental stewardship Reduce and manage stormwater runoff on site Provide irrigation for grounds without utilizing potable water Client: Nelson County Visitor's Center Challenge Supply water for irrigation needs around the building, while reducing municipal water use. Application Above ground tank for demonstration purposes 3,400 gallon belowground tank to supply irrigation needs Benefits Education Promote environmental stewardship Reduce potable water demands for nonpotable needs Client: Claude Moore Education Complex Roanoke, Virginia Renovation project for infill development on First St. in downtown Roanoke. The completed facility will provide space for teaching kitchens for a culinary arts program offered by the Virginia Western Community College. Challenge Divert water from rooftop system to supply water for flushing toilets. Application Siphonic roof drain system Two 2,500 gallon storage tanks Two vortex fine filters Benefits Reduce potable water demands for nonpotable needs Reduce stormwater runoff Effectively move water from rooftop to storage tanks Client: Non-profit organization White Hall, Virginia Challenge To provide the small non-profit a safe and reliable water source for building and greenhouse needs. Application One 1,500 gallon aboveground storage tank Two downspout filters Benefits Reduce potable water demands for nonpotable needs Have self-sustaining water supply Reuse soft, clean rainwater for greenhouse needs Client: Eggleston Services Eggleston Services, a non-profit organization in Norfolk, Virginia, dedicated to providing work opportunities for people with severe disabilities. Challenge Integrate a rain water-capture system into its new 34,000 square foot laundry facility in order to drive down the cost of water, energy, and chemicals. Application Rain is channeled from an all-rubber roof into a network of drainpipes in the ceiling and into two 10,000-gallon polyethylene tanks located at the back of the facility. Benefits Water from the storage tanks is pumped through three separate filtration systems into the laundry building where it is used as wash water. Rain water is fed into the boilers to partially fuel the steam-heated ironers. The storage tanks fill with one-inch of rain. The harvested rain water provides up to 15 percent of the laundry water requirements. Based on the average rainfall, the system yields 72 days of laundry operation. In a drought, the harvested rain water will last for 3-4 days. The rain water stored in the tanks maintains an ambient temperature of 82 degrees, thus reducing the energy required to heat the wash water. The return on the rain water harvesting system investment was 12 months. Client: IKEA Group IKEA Group, an organization that operates over 100 retail furniture stores around the world had a new retail store in Paramus, New Jersey, scheduled to open in the Fall of 2003. Challenge IKEA has strongly favored the use of siphonic roof drainage for their retail and warehousing facilities in Europe. IKEA wanted the New Jersey store to be the first IKEA store in the United States to utilize siphonic drainage. John Rattenbury is currently the only engineer in the United States capable of providing siphonic roof drainage design services. Application Rain is channeled from 250,000 square feet of roof area at a design rainfall intensity of 5.0" per hour. This system replaces a conventional system of eight downspouts sized at 10" to 12" with only five downspouts sized at 8" and 6". Benefits Siphonic systems are ideal for low-rise buildings with a vast footprint. Such buildings include airport terminals, covered malls, office complexes, warehouses, aircraft hangers, train stations, convention centers and factories. Siphonic piping does not have to be pitched like traditional open channel drainage, the piping system requires no more space than other pressurized mechanical piping systems. Fewer downspouts means fewer chances of interfering with architecture. When operating in siphonic mode, water velocities in the piping reach up to 26 feet per second making the system self-cleansing.
