Elliptical Tanks

Elliptical tanks use a combination of circular and rectangular structural designs and are the optimal shape for oxidation ditches and other activated sludge applications. Dutchland precast post-tensioned concrete elliptical tanks use a combination of circular and rectangular structural designs and are the optimal shape for oxidation ditches and other activated sludge applications. Each structure is custom-designed by our experienced engineering team to meet the specific needs of each project. Dutchland elliptical tanks are designed to AWWA D115 Standard and/or ACI 350 Standard and can be constructed as single or multiple interconnected concentric channels to accommodate process needs or site constraints.
