“…Most studies have shown that the operational phase of the life cycle has the largest environmental impact, and that electricity consumption for pumping and treatment is a significant contributor to the system's impacts. Assessments of decentralized and/or source separation systems are less common, but have become more frequent in recent years (Gardels, 2011;Glick and Guggemos, 2013;Lam et al, 2015;Lehtoranta et al, 2014;Lemos et al, 2013;Matos et al, 2014;Shehabi et al, 2012;Thibodeau et al, 2014).…”

The challenges of high quality water for domestic use and particularly for potability must be overcome in its entire ramification for health and ecological environment. The aim of this study is to identify the conditions of domestic water sources in Ado-Ekiti. One water sample was drawn from the two different sources of water, that is, shallow well and Ureje River at Ureje, and two samples from one water source, that is, borehole at Ilupeju and ABUAD in Ado-Ekiti. Water samples were analyzed in the Laboratory. Parameters including turbidity, pH, jar, hardness, calcium hardness and alkalinity were determined. Results revealed that the water samples drawn from borehole were of good quality following WHO reference guidelines, whereas, for water from well in Ureje and from river in Ureje, the concentration of these parameters exceeded WHO reference guidelines. It can be concluded that water obtained from Ureje River and that from well in Ureje are unsuitable for drinking (based respectively on colour, turbidity, odour, jar and hardness as well as pH, jar, turbidity, colour, and odour). However, pH, calcium and alkalinity are good following WHO reference guidelines. Further, well in Ureje contained water which is suitable for drinking and domestic uses. Samples drawn from borehole were the most suitable following WHO reference guidelines. However, further improvement is required. Detailed studies revealing the underlying reason for drop in quality of deep groundwater in the study area are required.

“…Such as, Anagnostopoulos and Vavatsikos (2012) used spatial fuzzy analytic hierarchy process to help with the site selection of wastewater treatment system. Glick et al (2013) combined LCC, LCA, and economic input-output to assess the sustainability of sewage treatment project. Zhou and Liu (2015) studied infrastructure projects from the perspective of micro engineering, with the aim of creating a basic model to analyze sustainable construction and operation of infrastructure projects, and a sewage treatment plant is used as a case study.…”

We conducted a second survey of household latrine based on the first survey study findings of rural facilities that toilet is the most significant influencing factor affecting farmers' satisfaction. The popularity proportion of rural sanitary latrines in China has been low, and the health of rural residents and the environmental sanitation in rural areas have not been effectively guaranteed. Factor analysis and logistic regression models are used to study the current situation of rural household latrines, rural residents' satisfaction and its influencing indicators of Sichuan. This research led to three key findings: 1) the present situation of rural household latrine construction in Sichuan is not ideal; 2) rural residents are relatively satisfied with rural household latrines; 3) rural residents' satisfaction is affected mainly by basic situation of latrines, village committee performance, recovery time, whether the latrine construction is worthy, transparency of village affairs, sources and subsidies of funds, construction participants and construction methods. Results of this study lay a foundation for further research about rural household latrines, and provide a theoretical basis for the construction and reform of rural household latrines in Sichuan.

“…Life cycle processes of wastewater treatment facility, as described previously, produce emissions either directly due to biological processes or indirectly as a result of energy consumption. Assessment of the potential environmental impacts of the life cycle of some wastewater treatment plants had been done in several places using the LCA (Foley et al 2010;Glick et al 2005; Kalbar et al 2013; Snip 2010). Glick dan Guggemos (2013) used the LCA to estimate the environmental impact of the manufacturing, construction, usage and maintenance phase of the facility.…”

Post-harvest handling / processing of fishery commodities requires large amounts of water and energy to overcome their perishable properties. Water is needed as raw/auxiliary material and to ensure that the production process and its environment meet the sanitary and hygiene principles. Meanwhile, large amount of energy is required for the transportation of raw materials and products, cold chain system during the process and operations of processing machines. They contribute towards the environmental impact of fish processing. This study used life cycle assessment to estimate the potential environmental impact of small scale mackerel fish processing. The results showed that the fish processing has contributed to 0.079 kg SO 2 eq acidification potential, 9.66 kg CO 2 eq climate chang-GWP 100, 0.02 kg PO 4 eq Eutrophication-generic, 0.17 kg 1.4 DCB eq human toxicity-HTP inf, and 0.0015 kg ethylene eq photochemical oxidation-high NO x. Wastewater treatment implementation simulation showed elimination of direct emissions that contribute to eutrophication and increasing the potential of other process associated with energy consumption.
