Green and Pretty: Build a Barrel rain reservation systems can be built in any shape to meet owners’ needs. The barrels are a product of Rain Reserve in Mansfield, which is helping home owners reuse rain water.

Rain. When your convertible is parked outside with the top down, it’s a real headache. When the heat has been relentless, it’s a welcome relief. A local company is offering another way to look at rain—as a valuable home resource.

Rain Reserve (802 N. Hwy. 5, Mansfield, 417-429-1356, is the invention of Enginuity, LLC, an environmentally conscious manufacturing company located in Mansfield. In 2007, Rain Reserve partnered with a Madison, Wisconsin, community program to build a rain collection system. The benefits, for both people and the environment, were obvious.

According to the James River Basin Partnership, a 1-inch rainfall drops 600 gallons of water on an average home with a 1,000-square-foot roof. With the help of Rain Reserve, a lot of this water can be reused for flushing toilets, gardening, washing the car and in water features. As a bonus, Rain Reserve President and Design Engineer Omar Galal says rain water is environmentally better than other sources. “When rain falls it collects a lot of nitrogen and phosphates,” Galal says. “City water has chlorine, which kills biology in the soil.” And the temperature of rain water is better for gardening. “If you’re using it on a 100-degree day, you’re using 100 degree water,” Galal says. “Cold water can shock your plants.” 

Galal says Americans use an average of 50 gallons of water a day. “Once someone starts saving 50 gallons of water, they’ll learn the value of that water and how much they’ll save,” he says. Fortunately, saving water doesn’t have to cost a ton of money. Galal says a person can start reserving water for $100. “If you’re trying to go green, or if you want to get off the grid, it’s a great way to start, because it’s not a big investment, but you get a lot of value out of it,” Galal says. 

Down the Spout: Rain Reserve's diverter kits attach to a home's downspout. While the rain water flows to a storage container, leaves and debris flow out of the spout. 

Rain Reserve uses a diverter kit attached to a home’s downspout. As water comes down, hydrostatic tension keeps fluid on the walls and debris in the center. Water is diverted into a hose that flows to a storage container, and leaves and other debris flow out of the spout. In addition to the diverters, Rain Reserve has a new rainwater storage option called Build a Barrel. Galal says the idea came from watching his 5-year-old son, Sharif, play with Legos. The containers, like Legos, can be built into any shape. This offers a variety of location options, whether under a deck, below bushes or even configured as a bench. Some people even grow plants on top of their Build a Barrel. Inside the containers, water is sealed, making it mosquito-proof.

All of Rain Reserve’s products are made locally. “I refuse to go to China to make parts,” Galal says. “Everything is made in the United States. The closer the better, but America for sure.” 

Build a Barrel systems start at 50 gallons and can be as large as 10,000 gallons. People can start small and add on according to their needs and budget. To learn more or to purchase a rain reserve kit, visit the store in Mansfield or go to Custom installations are also available for $3 to $6 per gallon.
