We-Mac

We-Mac was founded in 1962 in Atchison, KS. Our market niche initially was small tanks (under 2,000 gallons) to the rural Midwest. 1966 found We-Mac beginning production of large shop fabricated tanks and later adopting the STI-P3 underground tank technology in 1983. Today we offer a full line of tanks from 50 gallons to 50,000 gallons to serve nearly all industries, both domestic and international.  We are a proud Member of the Steel Tank Institute and licensed to build nearly all of the latest technologies offered through the Institute including: Fireguard fire-rated tanks, Flameshield Tanks, GenTank Generator Base Tanks, and ACT100U Underground Tanks. In addition, we also offer a full line of UL listed tanks, farm tanks, stainless steel industrial tanks, rectagular lube tanks, and portable tanks for all industries.  Our founding partners, Gene McCarty and Gene Harris, established a rock solid foundation for the Company to build upon. The Harris family continues their consistent leadership today, committed to upholding the legacy of our founders.
