The situation in the city of Bamenda has obliged the population to resort to doubtful sources and is exposed to water borne diseases despite the multiple water supply systems in the city. The study aimed to assess the state of urban household drinking water in the city of Bamenda. In order to meet the objective, a total of 420 questionnaires were administered to households in the three Sub-Divisions of the city accompanied by interviews. Data was analysed by use of the Statistical Package for Social Sciences (SPSS) version 25, Microsoft excel and Microsoft word 2016. Findings reveal that, multiple water supply sources prevail in the city (pipe borne water 65%, boreholes 18.6%, wells 8.3%, and spring/stream 8.1%) with three major pipe borne water suppliers. Approximately 25% of the study population obtained water from sources located off their premises and an average of 79.9% of the 25% spend over 30 minutes trekking for over a kilometre to fetch water. There is high financial cost in acquiring home water connection with an average rate of 200,000 FCFA (333.26 U.S Dollar). Since 2005 the city population has not met the minimum water of 50 l/p/d. In order to solve the water insecurity within the city, the study proposed that all water providers should ensure transparency, accountability, participation, the development of new water infrastructures and improvement on existing ones and financial support from the state.","PeriodicalId":487198,"journal":{"name":"Environmental Management and Sustainable Development","volume":"46 26","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134901715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its growth demands a large volume of water, encouraging the search for alternative water sources, such as fertigation with cattle wastewater. However, as it is a fecal-origin material, this practice can increase the initial microbial load of the vegetable and affect the efficiency of the sanitation process. Thus, the objective of this study was to evaluate the efficiency of domestic sanitation with sodium hypochlorite solution of lettuces obtained with different dosages of fertigation with wastewater from dairy cattle. After the sanitization, samples of all treatments showed lower number of total Coliforms, Escherichia coli and Aerobic Mesophiles. However, lettuces grown with 200% and 300% of the recommended dose of nitrogen showed microbial counts higher than those declared safe for consumption even after sanitization. There was no development of Salmonella spp. Although the productivity of the vegetable has increased with this irrigation technique, the limit of 100% of the recommended dose of nitrogen must be respected, since higher doses caused the persistence of pathogens at unsafe levels for human health even after the sanitation process. However, fertigation proved to be an outstanding alternative for saving water resources and proper disposal of wastewater.","PeriodicalId":487198,"journal":{"name":"Environmental Management and Sustainable Development","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135265944","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
