Abstract
The problem of corrosion of sanitary sewer concrete concerns the elements located just behind the expansion well. Evolving odorogenic substances and bioaerosols spread in the sewage system, cause in adverse conditions both chemical and biological corrosion of concrete. The paper presents the results of tests of samples taken from the top concrete circle and from a corroded cast iron hatch of 7 years old manhole located below the expansion well. Well elements were subjected to a strong

Many major cities such as Sydney have extensive networks of water supply pipelines, including major trunk lines that are ageing and increasingly prone to failure. Many of these pipes are made of cast iron. This material is traditional and has been shown to have excellent long-term durability, with many pipes surviving well past 100 years. Others, however, fail much earlier, and often this is through corrosion of the external surfaces of pipes. Such corrosion usually leads to weakening of pipe
