Item Environmental audit of the desalination plant in Gangehi Island Resort, North Ari Atoll(2011-07) SandcaysThis report has been prepared in order to assess the environmental performance of the existing desalination plant for the purpose of registration of the plant according to the requirements of the Environmental Protection Agency. This report focuses only on the desalination plant and no other operations of the resort are incorporated within the context of this report. Environmental Impact Assessment (or Audit) is required for the registration of desalination plant under the Desalination Regulation of the Maldives. Also, desalination plant projects fall within the list of projects requiring Environmental Impact Assessment study under the Environmental Impact Assessment Regulation of the Maldives. However, since the desalination plant in Gangehi (like many other such facilities in the Maldives) has been operational when the Desalination Regulation and the EIA Regulation came into effect, the scope for this Environmental Impact Assessment has been based on that of an environmental audit of the existing facilities, focusing on the environmental compliance and performance of the existing desalination plant. Therefore, this report will include a compliance and performance audit. The compliance audit or review will assess how well the project implementation complies with the existing environmental policies or requirements by the registering authority and the performance audit will assess the actual environmental impacts of the project and how well the impacts have been mitigated during the construction as well operational phase. The performance audit will also include a review of the existing monitoring programme, discussing the deficiencies and suggesting improvements for future monitoring. There have not been any legal requirements for environmental monitoring as there has not been any EIA report for the resort facilities under consideration. Therefore, this report is based on the findings of site investigations carried out by the consultant and necessary information provided by the management and technical staff at Gangehi resort. However, it is noted that the resort has a system in place to monitor environmental performance indicators of which water quality tests undertaken in the recent past by the Proponent have been used in preparing this report. In addition to discussing the findings of the audit, a matrix will be presented which summarises the status of environmental compliance and performance for activities involving the operation and maintenance of the facility. This report will also provide recommendations for further environmental improvements to the desalination plants.Item Item Item Environmental audit report : desalination facilities Thundufushi Island Resort South Ari Atoll, Maldives(2011-04) SandcaysThis environmental audit report addresses the environmental concerns of the existing desalination plant in Thundufishi Island resort. The primary objective of the audit exercise is to renew desalination plant registration. Having an environmental clearance statement is a requirement for the registration of desalination plants. In Thundufushi, there is one seawater desalination plant with daily production capacity 150 m3 in which feed water intake and brine concentrate discharge is on the eastern side of the island. The overall performance of the desalination plant in Thundufushi island resort is adequate and acceptable. However in the audit exercise conducted it was identified that water quality monitoring has not been conducted regularly and water quality records are also not available at plant site. Water quality was tested from four areas which are identified four potential impact areas including feed water intake zone, brine disposal site, groundwater within the plant operation and product water (desalinated water). The electrical conductivity of product water was found at 700μS/cm and no coliforms were detected from product water. The groundwater quality in terms of electrical conductivity was found at 6800μS/cm (considered as measure of salinity), this shows the aquifer is saline compared to freshwater aquifers in other islands across the Maldives. A monitoring programme has been outlined at the end of the report which can be implemented for environmental quality improvement and informed decision making. In particular, water quality monitoring and daily log maintenance at plant site. The overall performance of the seawater desalination facility in Thundufushi is at adequate and acceptable. Key aspects of the operations are in compliance to Desalination Regulations of the Maldives.
