A geyser in a stormwater (SW) and combined sewer system (CSS) is a high frequency oscillatory release of a mixture of gas and liquid that occurs at vertical shafts and other relief points. The oscillating jet of gas-liquid mixtures may reach a height of the order of a few to tens of meters above ground level. A considerable number of hypotheses were formulated for the causes of these geysers. Using actual geyser formulations, it is not clear how to predict a large geyser height as observed in actual stormwater and combined sewer systems. This paper describes a new theory on the causes of geyser occurrence and presents a simplified model for quantifying geyser eruption based on simultaneous exsolution of multiple gases. This model was applied to a geysering event in a stormwater collection system in Minneapolis.
