dc.description.abstract1. The purpose of this EIA is to critically analyse and assess the potential environmental impacts associated with the development of the proposed water production and distribution facility at HDh. Hanimaadhoo 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; 2. Currently, rainwater is widely used in all houses as cooking water and groundwater is used for various other domestic uses. Almost all houses have a rainwater storage tank. Bottled water is now mainly used as drinking water. Nevertheless, the groundwater lens in the islands of Maldives is depleted and highly saline due to over use and polluted in some areas and not fit for use for domestic purposes. Even though rainwater is widely used, it is not a reliable source as rainwater cannot be collected during dry season. Therefore, it is understood that Hanimaadhoo is in dire need of a clean water facility; 3. In the proposed facility the water production system is designed for 15 years whereas the distribution system for 35 years; 4. Proposed project involves installation of an RO plant with a capacity of 100 tonnes per day with three independent drains. Seawater intake is proposed from two bore wells 13 m deep at a site near the desalination plant. In addition to the bore wells, the facility will also incorporate rain water collected from public roofs, hence this is an integrated water resource management facility. Project also includes laying of distribution pipeline to existing household and a fire hydrant system; 5. A full baseline of groundwater quality, seawater quality, vegetation clearance and marine environment was established. It was found that the vegetation need to be cleared from the pump station location. Marine environment study showed that living substrata and fish count at the proposed outfall location was low due to dynamic oceanographic conditions that exist on the eastern side of the island with waves, swells and heavy currents which prevents settlement of new corals. Additionally, it is a high mixing zone; 6. The construction works of new powerhouses 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; 7. Overall, the proposed project is expected to bring in positive outcomes. It is expected that the newly established water production and distribution facility will ensure water security to the population of Hanimaadhoo in addition to greatly reducing health impacts associated with the use of polluted water; and 8. Monitoring is essential to ensure that environmental thresholds are not exceeded and mitigation measures proposed are working. Water quality and marine environment monitoring shall be done as per to the proposed monitoring schedule.en_US
