Summary: Achieving universal access to water and sanitation services in developing countries requires a coherent legal, political, and institutional environment, along with a clear financial strategy. Regionalizing utilities may be crucial for addressing disparities, economic inequalities, and governance challenges. Additional financial support may be required to ensure universal access, and tariff adjustments must strike a balance between cost effectiveness and affordability for families.

Summary: The quality of drinking water in China has shown an upward trend from 2007 to 2018, with urban drinking water qualification rate (85.51%) much higher than rural (51.12%), dry season (56.93%) higher than wet season (50.54%), and tap water (59.88%) higher than waterworks outlet water (55.87%). The regions with low water quality qualification rates were mainly in southern provinces like Yunnan, Guizhou, and Hainan. The lowest qualification rates were for microbiological indicators, all below 85%. Overall, the sanitation status of drinking water in China is unsatisfactory, with microbial pollution posing the biggest risk.

Summary: The concept of multiple deprivation recognizes that individuals, households, and communities often face multiple forms of scarcity. This study found that children who were not vaccinated with the DPT vaccine were more likely to experience other forms of deprivation, with the strongest associations found with maternal education, water, and sanitation.

Summary: This study found that contextual factors have a significant impact on the outcomes of rural sanitation interventions, but the direction and extent of the influence may vary between different countries, requiring tailored intervention measures. By using publicly available high-resolution datasets, interventions for rural sanitation activities can be targeted to the most favorable contexts.

Summary: The provision of potable water is of utmost importance for the health and dignity of individuals, but waterborne diseases pose a significant public health problem in many developing countries like Ethiopia. This study aimed to assess the prevalence and factors associated with Household Water Treatment (HWT) practices in Ethiopia. A comprehensive search of published studies was conducted, and data were analyzed using statistical software. The findings revealed a low overall proportion of HWT practice in Ethiopia, with factors such as education, gender, income, water source, fetching frequency, and water treatment training being associated with HWT practice. The authors recommend strengthened health education and intensive training to improve HWT practices in households.

Summary: This study evaluated the effect of alternative filtering materials and bed aeration on the retention of nutrients and fecal bacteria in woodchip bedded stand-off pads for cows. The results showed that the alternative biofilters were more efficient in removing COD, SS, TN, and NO3-N, while conventional biofilters were more efficient for PO4-P removal. Aeration did not have a significant effect under the tested temperature conditions.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.

Summary: In this study, an electron beam excitation multi-wavelength ultraviolet (EBE-MW-UV) system was established and found to have significantly higher microbial inactivation effects compared to single-wavelength UV-LEDs in water. Mechanism analysis revealed that EBE-MW-UV damaged microbial DNA and proteins, and generated additional reactive oxygen species, leading to microbial inactivation.

Summary: This study focuses on the development of an air-lift bio-electrochemical reactor (ALBER) with a continuous feeding regime to enhance nitrogen removal from synthetic wastewater. The effect of temperature, hydraulic retention time (HRT), N -NH+4 /TN ratio, and current density on the reactor performance was investigated, and the ALBER achieved a maximum TN removal of 73%. The results suggest that the ALBER has potential for treating industrial wastewater at low temperatures.

Summary: The exacerbation of global warming, extreme weather events, and rapid urbanization have led to increased flooding in urban areas. China has adopted sponge city as an efficient means of preventing and controlling urban floods. Using a SWMM-FVCOM model, the hydrological reduction and control effect of sponge city construction (SPCC) within a university campus were evaluated. The study found that implementing SPCC effectively mitigates surface runoff and reduces the severity of urban flooding. However, the efficacy of runoff control decreases with longer rainfall return periods.
