Summary:   The potable water industry makes significant use of concrete structures, especially tanks. Though frequently marketed by fabricators as “maintenance-free” concrete assets need to be a part of an ongoing sustainable asset management program, of which coatings are an integral part. Currently, the vast majority of these structures are uncoated. Concrete, a heterogeneous material, often has a variety of inherent defects including porosity, drying-shrinkage cracks, bug holes, honeycombing, and cracks. Over time, spalling and additional crack formation may lead to structural issues potentially endangering the asset. The very nature of uncoated concrete creates an environment where significant water quality and compliance issues associated with biological fouling may exist. In order to determine the magnitude of biological fouling and mineral deposition on uncoated vs. coated concrete a study was conceived and carried out under laboratory conditions. The results of the study will be discussed herein. Additionally, an overview on the basics of concrete, concrete in water systems, and problems associated with concrete will be presented. A discussion on maintenance to protect the asset, NSF approval of materials, and improved water quality will allow the Owner to easily see the benefits of coating existing and new concrete structures. Lastly, several examples of ‘before and after’ projects will be discussed. In summation this presentation provides compelling evidence for coating concrete structures in the potable water industry.
