Controlling corrosion, done properly, can help extend the useful life of water infrastructure. Effective prevention or mitigation strategies to control corrosion are appropriate for the material and the environment involved, as well as economically feasible.

The newly revised and renamed Manual M27 presents a logical and well-considered look at
1.How and why corrosion occurs
2.How to evaluate the corrosion potential of an environment
3.How prevention and control measures operate

Updates to this third edition were made to the figures, tables and text, including discussion of the effects of chemicals on pipe materials, pitting and crevice corrosion, common water pipe coatings, and recommended protective methods for specific pipe materials. New or expanded information includes stray current corrosion, microbiologically induced corrosion, oxygen-concentration cells, galvanic corrosion, and stainless steel in aboveground environments. Additionally, lab and field measurements to determine corrosive conditions are emphasized.
