Corrosion in Wastewater Treatment Plants (WWTP) has always been a problem. As systems increase in size, corrosion of materials in certain areas of the plant can become more serious. Concrete is the primary material used in WWTPs, and it can be severely corroded by the environment in a WWTP.

This paper discusses some of the more common types of WWTP corrosion, which occur in both concrete and metallic structures. Corrosion caused by poor design will be discussed also. Examples of corrosion will be described and practical solutions for restoration of corroded surfaces will be presented. The advantages and disadvantages of various restoration methods will be compared and alternative construction methods and design changes will be offered. These alternatives will improve the corrosion performance of common construction materials.
