"Production and build-up of sulfide and methane in wastewater collections systems causes several detrimental effects. Sulfide accumulation in sewers causes: i) odour nuisance in sewer surrounding areas, ii) health hazards due to its toxicity, and iii) corrosion of pipes and inlet structures of sewage treatment plants. On the other hand methane is a greenhouse gas with significantly contributing to global warming. Despite these significant impacts, sewer-produced sulfide and methane are yet to be considered in the management of Mediterranean Urban Water Systems. Additionally, detrimental emissions are expected to increase in the Mediterranean region due to predicted climate change and water scarcity scenarios. The current research project aims to study and mitigate the production of sulfide and greenhouse gas emissions from sewers exposed to Mediterranean climate conditions. The project methodology combines extensive experimental work on real sewers with advanced mathematical modelling to provide effective applicable control measures. The objective is to carry out the first quantification of sulfide and methane from Mediterranean sewers and also to create advanced management tools that include control of sewer emissions for optimal operation of urban water systems."
