"Winkelman's Environmentally Responsible Construction (WERC) company is a division of Eco-Domes LLC. Eco-Domes LLC is a newly formed company building on the Environmentally Responsible Construction success previously engaged in as part of The WATER Foundation.

In 1988, we began producing and syndicating educational network radio programs featuring Do-It-Yourself conservation tips. Starting with a few stations in 1989, we have grown to air on over 2000 radio stations in America, the World Wide Christian Radio (WWCR), and the Armed Forces Radio Networks (AFRTS) around the world. Among our radio properties are Natural Ways™, Outdoor Trivia®, Ocean Planet Trivia, Frog Friendly® Tips, and Eco-Auto® Tips. Our award-winning programs have the largest audience of any conservation program on radio today, measured by Arbitron to be over 10,000,000 adult listeners (ages 25-54). Our primary topics are: Water, Energy, Nature, and Health. Our state of the art production studios house the capability to produce our educational vignettes and distribute them to our network of 2000+ radio affiliates.

As the radio syndication gained momentum, listeners began requesting information, installation and service on conservation technologies described in our radio tips. In 1996-97 we built an environmentally responsible headquarters building near Brainerd, MN to display and demonstrate more of the technologies. As the interest and orders for technology began to increase, TWF organized a team of consultants, engineers and contractors to help its customers.

TWF personnel travel to locations in the five state Midwest area for consulting/planning meetings, workshops, constructing and servicing select projects as necessary to make our business flourish. TWF also has associations with Energy/Water/Building technicians, educators and professional installers in many areas of the country. Our track record and national business base will show that we are capable of handling needs for both small and large projects.
