Technical Report
Environmental impact assessment for proposed water production and distribution facility at Naifaru Naifaru, Lhaviyani Atoll, Maldives
(2017-01-01) Zuhair, Mohamed; Fathah, Mariyam Shujaa Ath A.; Shareef, Mohamed
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 Lh. Naifaru 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 for cooking and drinking whilst 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 residents of Naifaru are in great 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 180 tonnes per day with three independent drains. Seawater intake is proposed from two bore wells 30 m deep at a site inside the desalination plant. Project also includes laying of distribution pipeline to existing household and a fire hydrant system; 5. A full baseline of seawater quality, vegetation clearance and marine environment was established. Marine environment study showed that living substrata and fish count at the proposed outfall location was low; 6. The construction works of new RO plant 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 Naifaru 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 the proposed monitoring schedule.
Technical Report
Environmental impact assessment for proposed costal protection works in S. Hulhudhoo, Addu City, Maldives
(2017-02-01) Zuhair, Mohamed; Fathah, Mariyam Shujaa Ath A.; Shareef, Mohamed
1. The purpose of this EIA is to critically analyse and assess the potential environmental impacts associated with the construction of revetment at the eastern coast of S. Hulhudhoo and associated dredging of burrow area 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. The study area, Hulhudhoo, lying on the outer reef of the southernmost Atoll of Maldives, is exposed to southern swell waves and refracted south west monsoon sea waves. As a result of the swell waves, a large area of the shoreline on the eastern side in Hulhudhoo has been eroded. The extend of erosion is about 1 km north of the existing seawall. This seawall was constructed in the year 2008 and is in need of repair. Evidently, shoreline protection on this island is required immediately, especially since human settlement area is very close to this affected area. The closest residential area to the eroded area is only about 50 ft. 3. Proposed project involves dredging of a lagoon area at the western side of this island at the access channel area to source fill material for the revetment construction and for back filling purposes; 4. A full baseline of seawater quality and marine environment was established at the proposed burrow area as well as the revetment area. Marine environment study showed that both the areas were abundant with seagrass communities; 5. Dredging of burrow area is expected to cause degradation of the marine environment due to sediment stir up and loss of marine habitat whereas impacts on the revetment area is mainly due to reclamation/backfilling works; 6. Proposed mitigation measures include 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 revetment will bring an end to erosion of eastern coast of Hulhudhoo and improve shore zone configuration as well; 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 the proposed monitoring schedule
Technical Report
Environmental impact assessment for proposed water production and distribution facility at Guraidhoo Guraidhoo, Thaa Atoll, Maldives
(2016-12-01) Zuhair, Mohamed; Fathah, Mariyam Shujaa Ath A.; Shareef, Mohamed
1. 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 Th. Guraidhoo 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. Although groundwater on this island is in a good condition, excessive use of this water runs the risk of depletion of groundwater lens similar to other inhabited islands of Maldives. 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 residents of Guaridhoo are in need of an alternate 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 80 tonnes per day with three independent drains. Seawater intake is proposed from two bore wells 30 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. Marine environment study showed that living substrata and fish count at the proposed outfall location was low; 6. The construction works of new RO plant 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 Guraidhoo; 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 the proposed monitoring schedule.
