| Abstract | ||
| A comprehensive survey has been made of the operational status and potential environmental impacts of Shoha model village’s primary wastewater treatment plant from January to December (2017). For this purpose, four water sources were sampled, namely raw wastewater (pretreatment), effluent discharge (post treatment), catfish muscles and sediment from Negeer Drain (the recipient watercourse of the treated wastewater) and the River Nile (the reference stream with comparatively low pollution regime). Analytical methods and measuring devices indicated that sediment of Negeer Drain which receives effluent discharge of Shoha model village’s primary wastewater treatment plant accumulated greater amounts of heavy metals, organic pollutants, total dissolved solids, bicarbonates, sulphates, chlorides and minerals than sediment of the River Nile. A similar comparative trend was relevant for water and fish muscle between Negeer Drain and the River Nile except for a slight, non-significant increase in Cu and Ni in Negeer Drain. The amounts of heavy metals, TOC, N, P and K accumulated in sediment samples were significantly higher than corresponding levels in water and fish muscles, except for chromium which recorded the lowest level in sediment samples in either habitat. The amount of BOD5 in water sampled from Negeer Drain was significantly higher than corresponding levels in water sampled from the River Nile. Nutrient enrichment, small-sized tanks and limited pumping vehicle, bacterial overload, organic pollution and heavy metals accumulation in Negeer Drain indicated that Shoha Primary Wastewater Treatment Plant is an inefficient treatment tool, in terms of potential environmental hazard and limited treatment capacity, and does not comply with Egypt’s Vision 2030. An integrated wastewater treatment program is highly recommended, including the expansion and/or rehabilitation of the existing plant, expansion of the sewerage network in addition to installation of pumping facility and provision of evacuation vehicles to serve rural area and urban slums which are deprived of access to upgraded hygiene and sanitation systems. The suggested project aims at promoting sustainability of natural resources consumption, upholding pollution prevention and diminishing ecosystem degradation. | ||
