Master's thesis of Engineering: Impact of drought and water conservation on H2S formation in sewer pipes

The aim of this research was to investigate the formation of hydrogen sulphide for different sewage characteristics and flow rates. An experimental set-up was developed to simulate a section of a gravity sewer pipe, the set-up comprised of a pipe of 2 m long and 155 mm inside diameter, referred to in this thesis as a laboratory sewer pipe. The first stage of the experimental program involved developing a biological growth rich in sulphate-reducing bacteria inside the laboratory sewer pipe using synthetic sewage.
