Onsite Treatment

House onsite treatment of grey water and reuse of treated effluent for irrigating crops are increasingly accepted and practiced in Palestinian rural developments as more than 600 units are operational. The main goal of this research was to assess the impact of those systems on the environment, health, and the Palestinian society and economy through field survey in Qebia village where 47 house onsite sanitation systems were recently implemented. The results revealed that the biggest incentive for applying this system is the reuse of treated grey water for irrigation purposes, which is socially accepted. The application of those systems is currently limited and tied to the availability of external funds. The main concerns people have over the constructing of those house onsite systems are health risks, flooding, and odour emission. Accordingly, the concept of house onsite wastewater management systems is very promising, but provision of proper technical solutions is very important.

This paper deals with the adverse effects of domestic wastewater on water utilization occurring as a result of a deteriorating water environment caused by the lack of an adequate domestic wastewater management system in Japan. Available domestic wastewater management systems are summarized from the viewpoints of performance and administration. Further, the factors to be considered in selecting an appropriate domestic wastewater management system for a projected area are discussed, and one typical example of a water environment, conserved well by comprehensive implementation of domestic wastewater management, is given.

Step Procedure

The steps of calibration/confirmation of models in a suggested 11-step procedure for analysis, planning and implementation of integrated urban wastewater management systems is focused upon in this paper. Based on ample experience obtained in comprehensive investigations throughout Europe recommendations have been formulated for design of measuring campaigns. The inclusion of iteration in the overall planning of measuring campaigns is advised and the use of preliminary sensitivity analysis is shown to allow maximisation of information retrieval from experimental efforts. Case studies covering problems related to suspended solids, specific contaminants, hygienic hazards and total pollutant loss illustrate the recommendations presented.

Wastewater-based epidemiology (WBE) is an approach that can be used to estimate COVID-19 prevalence in the population by detecting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA in wastewater. As the WBE approach uses pooled samples from the study population, it is an inexpensive and non-invasive mass surveillance method compared to individual testing. Thus, it offers a good complement in low- and middle-income countries (LMICs) facing high costs of testing or social stigmatization, and it has a huge potential to monitor SARS-CoV-2 and its variants to curb the global COVID-19 pandemic. The aim of this review is to systematize the current evidence about the application of the WBE approach in mass surveillance of COVID-19 infection in LMICs, as well as its future potential. Among other parameters, population size contributing the fecal input to wastewater is an important parameter for COVID-19 prevalence estimation. It is easier to back-calculate COVID-19 prevalence in the community with centralized wastewater systems, because there can be more accurate estimates about the size of contributing population in the catchment. However, centralized wastewater management systems are often of low quality (or even non-existent) in LMICs, which raises a major concern about the ability to implement the WBE approach. However, it is possible to mobilize the WBE approach, if large areas are divided into sub-areas, corresponding to the existing wastewater management systems. In addition, a strong coordination between stakeholders is required for estimating population size respective to wastewater management systems. Nevertheless, further international efforts should be leveraged to strengthen the sanitation infrastructures in LMICs, using the lessons gathered from the current COVID-19 pandemic to be prepared for future pandemics.

Abstract The cesspit septage quality and pollution loads of total nitrogen (TN) and heavy metals (HMs) from 50 cesspits were assessed during various filling periods. The average specific wastewater production, emptied septage and infiltrated septage were 49, 30 and 19 L/c d, respectively. The TN specific loads of septage fractions that were emptied and infiltrated were 8.5 and 3.3 g/c d, respectively. The concentrations of HMs (mg/L) in the septage were Cu (0.24), Ni (0.03), Pb (0.01), Mn (0.47), Fe (12.6), Cr (0.04) and Zn (1.23). The septage content of Cu, Mn and Fe did not comply with the Palestinian regulations for wadi disposal nor effluent reuse in agriculture. The specific TN infiltration from cesspits amounts to 29 kg TN/ha y. There was no relation between the HM and TN content of septage and the desludging frequency. The infiltrated septage contributed to as much as 15% of the total groundwater recharge in the study area. This study confirms that cesspits in Palestine should be replaced with proper wastewater management systems for adequate environmental protection.
