Manada Construction Company has served the agricultural community for 35 years, excavating sites for dairy, swine, and poultry farmers as well as working with the conservation districts in implementing conservation practices. During this time, as farming operations grew, a demand arose for a better way to store manure than the typical clay or concrete lined earthen manure storage. It was 15 years ago while working with a prominent hog producer on a large sow operation in shaley ground that we first installed an H.D.P.E Liner for animal waste storage.
