Abstract: Deterioration of Sewage pipes and Sewage treatment plants (STP) is of major concern due to
difficulty in maintenance and high cost of replacement in the future. Most of these systems
undergo degradation due to Biogenic sulphuric acid (BSA) attack. Since most of Waste water
treatment system are underground, detection of this deterioration remains hidden. This paper
presents a literature review, outlining the mechanism of this attack focusing on critical
parameters of BSA attack, along with available models and software to predict the
deterioration due to this attack. This paper critically provide focus on various steps and
equation in various models of sulphate degradation, some detail on working of different
software are also highlighted in this paper. The paper also focuses on the service life design
technique available through various codes and method to integrate the servile life design with
BSA degradation. In the end, various methods to enhance the resistance of structure against
Biogenic sulphuric acid attack are highlighted. It may be concluded that the effective
modelling for degradation phenomena may bring positive economic and environmental
impacts. With current advance computing capabilities integrated degradation models
combining the various durability aspect are must for a sustainable society.
