Due to urban sprawl more and more communities and engineers are taking additional steps to protect and extend the service life of new and existing wastewater structures. A municipality in one such area controls a pumping station that has been degrading slowly over time. The walls of these stations are particularly susceptible to the corrosive environment and will easily deteriorate without protection. As infiltration and the effect of corrosive gases are the two primary causes of deterioration in a collection system, the addition of a corrosion barrier to a new structure will not only ensure a longer service life to the system, it will make the rough concrete surface easier to clean.
