Item Environmental impact assessment for establishment of sewer network at Aa. Ukulhas(2018-01) Wahhab, Mahfooz Abdul; Adam, Ibrahim RashihuThe purpose of this EIA is to critically analyse and assess the potential environmental impacts associated with the establishment of a sewer network in AA.Ukulhas and expose the solutions and preferred alternatives as well as mitigation measures to minimize any negative impacts whilst trying to derive the maximum positive impacts from the project; Existing sewer situation at the aforementioned island are not proper and are subject to cause ground water contamination. In this sewer establishment project, sewer facilities are proposed to be constructed at a location whereby public nuisance could be minimised along with little disturbance to the natural setting of the proposed locations of sewer facility and allied pump stations for the network. All the components of the sewer network will be constructed according to EPA specification complying to both MEE and EPA regulations; Additionally, this study also involved identification of several alternative locations for laying the outfall and selecting the most ideal location based on thorough study of the current patterns, proximity to the public recreational beaches and ease of design effectiveness. The preferred locations were selected based on best met design criteria of EPA and environmental options; The construction works of sewer network presented in this report are not expected to adversely impact the environment if the mitigation measures mentioned in the report are followed. The most important mitigation measures are daily maintenance of machinery, following chemical handling procedures, waste segregation and storage in closed labelled containers until disposal to Thilafushi and most importantly following the EPA guidelines for operation of sewer system; Potential groundwater contamination from damages to sewer network, potential impacts to marine life from discharge of sewerage from the outfall, excavation and dewatering are the most significant environmental impacts associated with the project. Therefore, it is extremely important to follow the proposed mitigation measure, relevant guidelines and regulations and the operation and maintenance manual of the sewer system during the operational phase. Overall, the proposed project is expected to bring in positive outcomes. It is expected that the newly established sewer network will ensure safe sanitation services to islandާ community in addition to greatly reducing further disturbance and contamination of the ground water and surrounding environment; and Monitoring is essential to ensure that environmental thresholds are not exceeded and mitigation measures proposed are working. Ground water and marine water quality monitoring will be done according to the proposed monitoring schedule.Item Environmental impact assessment for development of indoor sports complex, Hulhumale', Kaafu atoll(2017-12) Wahhab, Mahfooz AbdulThe purpose of this EIA is to critically analyse and assess the potential environmental impacts associated with the proposed development of a sports complex at Hulhumale and expose the solutions and preferred alternatives as well as mitigation measures to minimize any negative impacts whilst trying to derive the maximum positive impacts from the project; Hulhumale is an island reclaimed in 2002 for the purpose of relieving the population congestion in Male’. During the first phase a total area of 188 Ha were reclaimed. And in 2004 the first population started living in Hulhumale’. Since then the population of the island had been growing rapidly, now with a population size greater than 65,000. In early 2015 an additional 244 Ha were reclaimed under phase II of the project with the intention of accommodating two thirds of Maldives population in Hulhumale’ with a targeted population size of 240,000. Therefore, it is understood that in order to increase the social well-being of such a huge population, proper social ventures which would cater for the youths are important on this island. A full baseline of groundwater quality was established at the proposed development area as it is anticipated to impact negatively on the groundwater quality. In addition to this, noise level and traffic flow of the area were surveyed. Additionally, this study also involved identification of alternative options in place of the proposed development. The considered options were no project scenario and moving project location, both of which are economically less feasible. Dewatering is the most significant negative impact which would arise due to the project as it is proposed to build a community swimming pool. Additionally, during the operational phase, it is anticipated that poor maintenance of the pool will cause the impacts of highest significance. The socioeconomic benefits during the operations far outweigh the negative impacts. It is expected that the proposed development will provide recreation facilities to the youth, indirectly minimising the social problems faced by the youngsters today. Moreover, the proposed project will also open many job opportunities, especially to the unskilled workers.
