The use of sacrificial concrete sewers for controlling sulfide related odor from sewers was investigated in this study. For the purpose of this study, three sacrificial concrete sewers were constructed with the intention of alleviating odor problems associated with discharging wastewater from force mains with extended hydraulic retention time. In all three locations, a 50 m long sacrificial concrete gravity sewer have been implemented in sparsely populated catchments. The monitoring campaign reported in this paper covers the first 5-7 years of operation. The results demonstrate the capability of the systems for reducing hydrogen sulfide gas (H2S(g)) concentrations in the sewer headspace. Based on the results of a sewer process model, the service life of the investigated sacrificial sewers were predicted to be several decades.
