Objective: Insanitary disposal of sewage is a problem that contributes to pollution and impacts negatively on human health. It contributes significantly to the prevalence of diarrhoeal diseases. This study was conducted to determine the knowledge and practice of sewage disposal among selected residents of Abattoir community of Jos South LGA, Plateau State.Methods: A multistage sampling technique was used to select respondents. Semi-structured interviewer administered questionnaires were used to collect data which was analyzed with Epi info 3.5.4. A p-value of < 0.05 was considered statistically significant for this study.Results: A total of 120 adults from selected households were interviewed. A mean age of 31± 2 years was found with a male:female ratio of 1:1.4. Adequate knowledge regarding sewage disposal was found among 94% of respondents. The flush/pour-flush toilet connected to septic tank, simple pit latrine and open defaecation were the methods found in use among them. The choice of sewage disposal type was statistically significantly related to level of education. Other reasons that influenced choice of toilet methods were hygiene, convenience, affordability and ease of maintenance. No cases of diarrhoea were reported in 90% of the households in the 6 months prior to the study.Conclusion: Despite the commendable findings in this community, the community is still at risk due to the poor practices of a few that were persisting in the community. Both government and community efforts are required to ensure that basic toilet facilities are available to all.Keywords: sewage disposal, knowledge, practice, urban community

ABSTRACTThe discharge of sewage to the unique UK coastal environment has been a traditional and cost‐effective means of treatment for many decades. This disposal option is increasingly questioned by professionals with public‐health responsibilities as well as by environmental pressure groups. There are limited firm data on the epidemiological significance of existing disposal practices: the established prospective methods, developed by North American workers in this area, have not provided a scientifically‐robust, epidemiological, research protocol. This leaves a scientific vacuum for those with operational and policy responsibilities in this important and sensitive area of water resource management.

A mathematical model for the design of marine sewage disposal systems in accordance with the criteria of the EU Bathing Water Directive is developed and applied to the design of the outfall of the sewage from Athens, Greece. The model calculates the reduction of fecal coliforms due to initial and subsequent dilutions and die-off due to the effect of solar radiation and predicts the concentrations of fecal coliforms at the bathing area for specific hours and current velocities. A combination of these results with the probability distribution of the velocity of the sea currents results in a frequency distribution of fecal coliform concentrations at the bathing area thus enabling evaluations with respect to conformity to the statistical criteria of the EU Directive. The application of the model to the disposal system for the sewage of Athens shows that conformity, without the use of effluent disinfection, can be achieved for the nearest bathing area, located at a distance of 3.4 km from the outfall, irrespective of the definition of the bathing hours (8 am-8 pm or 24 hrs) and for a sufficiently conservative mortality rate. These results indicate that under Mediterranean or similar conditions, with typical wind induced currents, a sewage field travel distance of a few kilometres is sufficient to ensure bathing areas against infection, without the need for sewage disinfection. It should, however, be stressed that these conclusions are valid on the assumption that the sampling procedures outlined in the EU Directive refer to uniformly distributed sampling throughout the bathing period of the day or season.
