{"title":"The use of reed plants for wastewater treatment: the Iraq experience.","authors":"A A al-Samawi","doi":"","DOIUrl":"","url":null,"abstract":"The use of plants, especially of species that grow naturally and under harsh environmental conditions, offers a simple and economic method of wastewater treatment. This method has been gaining wide popularity throughout the world over the last decades. Iraq is considered to be a country with environmental conditions favourable for the natural growth of many aquatic plants such as reed (Qassab). The root-zone method of treating wastewater is suitable for Iraq, e.g. because of its economy and the fact that such treatment does not need sophisticated mechanical or electrical equipment, or chemical materials. The most important aspect is that this method makes use of a weed, namely the reed. A mobile test tank for root-zone treatment stationed in the Rustamya sewage treatment plant and run for nearly 34 weeks. A total of 768 samples of the influent and effluent sewage were analysed. Average removal efficiencies for biological oxygen demand, suspended solids, chloride, phosphate and ammonia ranged from 92 to 82%, and chloride was removed with 13% efficiency. These results indicate that the root-zone method is adequate for the treatment of domestic sewage and can compete with conventional treatment methods whose average effluent concentrations for BOD5 and suspended solids are similar. A survey of water quality was conducted on a drainage ditch north-west of Baghdad to assess its natural purification process. The ditch that was chosen was infested with reed plants and other aquatic weeds. The role of the macrophytes was found to be essential in the process of self-purification of the water body. Results of the survey indicate that such ditches and streams could be used as disposal points for domestic sewage and industrial wastes. However, further assessment of their performance particularly for removal of suspended solids, pathogens, phosphate and nitrogen is necessary. The results indicate that reed beds may be suitable particularly for treatment of wastewater from small and remote towns and villages in Iraq.","PeriodicalId":76530,"journal":{"name":"Schriftenreihe des Vereins fur Wasser-, Boden- und Lufthygiene","volume":"105 ","pages":"311-7"},"PeriodicalIF":0.0,"publicationDate":"2000-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21686507","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}

{"title":"Re-engineering the urban drainage system for resource recovery and protection of drinking water supplies.","authors":"B Gumbo","doi":"","DOIUrl":"","url":null,"abstract":"The Harare metropolis in Zimbabwe, extending upstream from Manyame Dam in the Upper Manyame River Basin, consists of the City of Harare and its satellite towns: Chitungwiza, Norton, Epworth and Ruwa. The existing urban drainage system is typically a single-use-mixing system: water is used and discharged to \"waste\", excreta are flushed to sewers and eventually, after \"treatment\", the effluent is discharged to a drinking water supply source. Polluted urban storm water is evacuated as fast as possible. This system not only ignores the substantial value in \"waste\" materials, but it also exports problems to downstream communities and to vulnerable fresh-water sources. The question is how can the harare metropolis urban drainage system, which is complex and has evolved over time, be rearranged to achieve sustainability (i.e. water conservation, pollution prevention at source, protection of the vulnerable drinking water sources and recovery of valuable materials)? This paper reviews current concepts regarding the future development of the urban drainage system in line with the new vision of \"Sustainable Cities of the Future\". The Harare Metropolis in Zimbabwe is taken as a case, and philosophical options for re-engineering the drainage system are discussed.","PeriodicalId":76530,"journal":{"name":"Schriftenreihe des Vereins fur Wasser-, Boden- und Lufthygiene","volume":"105 ","pages":"15-21"},"PeriodicalIF":0.0,"publicationDate":"2000-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21686988","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}

In many developing countries, groundwater taken directly (untreated) from individual springs and wells is the only option available to communities where comprehensive, reliable reticulated supply systems are absent. A common feature of urban groundwater in both developing and developed countries is contamination by sewage. Current and recent research is presented that shows sewer leakage impacts groundwater in developed countries whilst on-site sanitation contaminates groundwater in developing countries. In the latter case, the competing demands of sanitation and groundwater protection must be addressed. Limitations on the usefulness of accepted standard sewage indicator species in groundwater are also highlighted. As sewage contamination of groundwater is usually addressed only if an actual health risk is posed, it is vital both to developed and developing countries to understand the movement of actual pathogens in groundwater in the context of groundwater management. Further research is required on microbial survival and health risks posed by sewage contamination.","PeriodicalId":76530,"journal":{"name":"Schriftenreihe des Vereins fur Wasser-, Boden- und Lufthygiene","volume":"105 ","pages":"179-85"},"PeriodicalIF":0.0,"publicationDate":"2000-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21687337","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}

Though the degree and the cause varied in each country, all the countries investigated had problems arising from contamination of water resources. It was found that there are several sources of water contamination, such as human and animal excreta, solid wastes from nearby houses, graveyards, contaminated river flows, and large-scale landfills for big cities. It was revealed that even when water is clean at the point of production, it could be easily contaminated through broken pipelines or improperly maintained containers. It is still rare to put chlorine into piped water supply and both the inhabitants' and water engineers' understanding of the importance of disinfection should be reemphasised. Although it is urgent to provide piped water supply to those who have only contaminated water sources, such as surface water and dug wells, it is also important to protect these limited water sources from the above-mentioned contamination.","PeriodicalId":76530,"journal":{"name":"Schriftenreihe des Vereins fur Wasser-, Boden- und Lufthygiene","volume":"105 ","pages":"399-404"},"PeriodicalIF":0.0,"publicationDate":"2000-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21688143","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}
