Concrete sludge mixing and storage tanks in wastewater treatment plants can be exposed to corrosive environments. Protective linings are the best solution to this problem. But, there are a number of design considerations based on this author’s experience that are not readily obvious at the outset. This paper will present a number of important design considerations based on lessons learned which can avert lining performance problems and ensure appropriate lining material selection. Specific examples from a number of sludge tank lining projects will be used to illustrate these design considerations.
