Rainwater HOG tanks have been making waves in the Japanese marketplace since 2010, with help from our distributor in Japan Ito Yogyo Co., Ltd.
Two Rainwater HOG tanks were installed in May 2010 in front of Ito Yogyo Co.’s Osaka storefront.
The two HOG tanks at the Osaka storefront collect 6,868 gallons (26,000 liters) of water annually.
Space for housing is limited to “narrow plots of land” in Japan, explains Mr. Yoshihiro Hagihara of Ito Yogyo, which makes the slim-lined HOG tanks a perfect fit for residential installations.
In fact, Rainwater HOG won the Japanese Kids Design Award in July of 2011. HOG was chosen not only because the HOG tank is an easy way to teach kids about the benefits of re-using rainwater, but also because of its superior, multi-purpose design. The tanks can double as an emergency water supply source, are easy to install, and the slender, architecturally-designed profile allows the modular system to fit into a tight space.
A HOG tanks collects rainwater in city of Ikoma, in the Nara Prefecture.
Garden irrigation and car washing are the primary uses of harvested rainwater for the environmentally conscious Japanese homeowners who have installed HOGs. For example, a homeowner in the city of Ikoma waters the kitchen garden with rainwater collected from one HOG (pictured left). The tank, chosen for it’s narrow profile, was installed in September 2011; it collects 3,434 gallons (13,000 liters) of water annually.
