“…Indeed, this sewer network has a short length and features almost exclusively gravity pipes (98%), hence only 2% of the network is pressurised (rising mains pipes). As reported in the literature, in-sewer H 2 S and CH 4 production occurs primarily in anaerobic rising mains with long hydraulic retention times (Hvitved-Jacobsen, 2002;Sutherland-Stacey et al, 2008). In general, longer pressurised rising mains networks with longer retention times and more pumping stations are expected to generate more GHG emissions (Gutierrez et al, 2009).…”

This study aims to propose a holistic, life cycle assessment (LCA) of urban wastewater systems (UWS) based on a comprehensive inventory including detailed construction and operation of sewer systems and wastewater treatment plants (WWTPs). For the first time, the inventory of sewers infrastructure construction includes piping materials and aggregates, manholes, connections, civil works and road rehabilitation. The operation stage comprises energy consumption in pumping stations together with air emissions of methane and hydrogen sulphide, and water emissions from sewer leaks. Using a real case study, this LCA aims to quantify the contributions of sewer systems to the total environmental impacts of the UWS. The results show that the construction of sewer infrastructures has an environmental impact (on half of the 18 studied impact categories) larger than both the construction and operation of the WWTP. This study highlights the importance of including the construction and operation of sewer systems in the environmental assessment of centralised versus decentralised options for UWS.

“…Sulfide concentrations during the 8-h cycle were continuously monitored using an S::CAN UV-visible light (UV-VIS) sepcitro::lyser (Messtechnik GmbH, Austria), as previously described by Sutherland-Stacey et al (18). In addition, samples were taken from the reactor before and after each pumping event and also at 2.5 h, 5 h, and 6.5 h for the analysis of dissolved methane, sulfate, total COD (tCOD), sCOD, and VFAs, using methods described by Jiang et al (3).…”

bSimultaneous production of sulfide and methane by anaerobic sewer biofilms has recently been observed, suggesting that sulfate-reducing bacteria (SRB) and methanogenic archaea (MA), microorganisms known to compete for the same substrates, can coexist in this environment. This study investigated the community structures and activities of SRB and MA in anaerobic sewer biofilms (average thickness of 800 m) using a combination of microelectrode measurements, molecular techniques, and mathematical modeling. It was seen that sulfide was mainly produced in the outer layer of the biofilm, between the depths of 0 and 300 m, which is in good agreement with the distribution of SRB population as revealed by cryosection-fluorescence in situ hybridization (FISH). SRB had a higher relative abundance of 20% on the surface layer, which decreased gradually to below 3% at a depth of 400 m. In contrast, MA mainly inhabited the inner layer of the biofilm. Their relative abundances increased from 10% to 75% at depths of 200 m and 700 m, respectively, from the biofilm surface layer. High-throughput pyrosequencing of 16S rRNA amplicons showed that SRB in the biofilm were mainly affiliated with five genera, Desulfobulbus, Desulfomicrobium, Desulfovibrio, Desulfatiferula, and Desulforegula, while about 90% of the MA population belonged to the genus Methanosaeta. The spatial organizations of SRB and MA revealed by pyrosequencing were consistent with the FISH results. A biofilm model was constructed to simulate the SRB and MA distributions in the anaerobic sewer biofilm. The good fit between model predictions and the experimental data indicate that the coexistence and spatial structure of SRB and MA in the biofilm resulted from the microbial types and their metabolic transformations and interactions with substrates. Sewer biofilms comprise complex multispecies microflora with a typical thickness of only about 1 mm (1). Depending on the electron donors and electron acceptors present in the wastewater, different carbon transformation processes can occur in close proximity in the sewer biofilms. Domestic wastewater normally contains a significant concentration (ca. 100 to 1,000 M) of sulfate but negligible nitrite and nitrate concentrations (2, 3). Therefore, under anaerobic conditions (which normally occur in pressure sewers fully filled with wastewater), sulfate reduction carried out by sulfate-reducing bacteria (SRB) could be an important terminal electron-accepting process in the sewer biofilms. The sulfate reduction activity in anaerobic sewers is important, as the production of sulfide can be transferred to the gas phase of partially filled gravity sewers and cause extensive corrosion of concrete sewer pipes (4, 5). Also, the emission of sulfide from sewers can cause odor problems for the surrounding area and pose health risks to sewer workers (6, 7). Apart from sulfate reduction, methanogenesis caused by the respiration of methanogenic archaea (MA) could also be a key terminal process in anaerobic sewer biofilms (8, 9). Guisasola and ...

“…Recent development of the UV-vis spectroscopy technology allows the simultaneous monitoring of dissolved sulfide and nitrate [67,68]. Another sensor has been developed more recently, which is able to measure dissolved sulfide and dissolved methane simultaneously with the use of an automated stripping chamber and gas-phase hydrogen sulfide and methane sensors [69].…”
