Item Environmental audit for registration of desalination plant at Vilamendhoo Resort, Alifu Dhaalu Atoll, Maldives(2011-04) CDE ConsultingThe purpose of this Environmental Audit report is to fulfill the requirements of Maldives Water and Sanitation Authority guidelines to get necessary environmental clearance from the Environmental Protection Agency to carry out the registration the utility services. The project involves auditing of the existing desalination plant in Vilamendhoo Resort and Spa. Desalination system involves two plants with capacity 200 m3 per day each and two water storage tanks with a capacity of 710 m3. The seawater intake is located on the southern side of the island with a length of 170 m from the desalination plant house. The brine discharge point is located on the northern side of the island at a distance of 130 m from the desalination plant house. The structural integrity of the facilities is considered good. Noise levels are perceived as high for a mixed residential and industrial zone although it must be taken into account that space is limited and location of staff areas near plant house is inevitable. The environmental impacts associated with this project include, increased noise levels and impact on marine environment due to brine discharge. There are indirect impacts associated with consumption of energy for desalination. Power generation has the potential to degrade air quality and contributes to global warming. In addition, fuel handling related to power generation is a potential risk for ground water and soil contamination from fuel spills and leaks. Noise measurements taken during the field visit conforms to international standards while marine water quality tests show normal conditions although there are limitations in the parameters tested due to unavailability of tests at National Health Laboratory. Marine life needs to be further monitored at the brine discharge location to ascertain whether there is a long term impact from discharge of brine. Visual observation identifies no notable damage to existing vegetation around the desalination plant house and no indication of any fuel spills or leaks around the area. Groundwater quality tests that could be conducted shows that the groundwater is in good condition. Mitigation measures that are in place to reduce the environmental impacts associated with the operation of the facility include appropriate distance of brine and seawater pipes from shoreline and installation of sound attenuators to reduce the noise levels from the plant house. In order to protect the environment from potential fuel spills, proper pipelines are established and fuel storage is in bunded areas. A monitoring plan is proposed to observe any changes taking place due to the operation of desalination plant. In the event that monitoring indicates that any environmental quality is deteriorating to unacceptable levels, the proponent will correct operation procedures that are contributing to the problem and/or undertake necessary engineering installations.Item Environmental audit for registration of desalination plant at Royal Island Resort & Spa, Baa Atoll(2011-04) CDE ConsultingThe purpose of this Environmental Audit report is to fulfill the requirements of Maldives Water and Sanitation Authority guidelines to get necessary environmental clearance from the Environmental Protection Agency to carry out the registration of the desalination plant.

The power generation system involves a powerhouse building that houses seven diesel fired generator sets with total capacity of 4585 KVA and a fuel storage facility with total capacity of 240,000 litres. Desalination system involves three plants with a total capacity of 210 tonnes of desalinated water per day and two water storage tanks with storing capacity of 1040 tonnes. The project involves improvements of the existing football ground which is dedicated to the staff purely for their recreational purpose. The major development proposed for this football ground is to level off the ground install drainage system. The structural integrity of the facilities is considered good. Noise levels are perceived as high for a mixed residential and industrial zone although it must be taken into account that space is limited and location of staff areas near powerhouse is inevitable. The main environmental impacts associated with this project include, increased noise levels and other emissions, potential risk for ground water and soil contamination due to fuel spills and leaks, damages to vegetation due to heat and smoke generated from the power house, potential impact on the marine environment due to brine discharge from the desalination process. Visual observation identifies no notable damage to existing vegetation around the powerhouse building and no indication of any fuel spills around the powerhouse area. Marine water quality tests identify no significant contamination. Groundwater quality tests are insufficient to draw conclusions. Improvement to the football grounds is not expected to cause significant adverse impacts. Drainage of water during operation phase will positively affect the groundwater aquifer by contributing to recharging of the aquifer. Mitigation measures that are in place to reduce the environmental impacts associated with the operation of the two facilities include planting of trees in high noise areas and improved maintenance of generator sets.In order to protect the environment from potential fuel spills, fuel storage facilities are bunded to contain any spills and proper pipelines are established for safe fuel transfers. A monitoring plan is proposed to observe any changes taking place due to the operation of powerhouse and desalination plant. In the event that monitoring indicates that any environmental quality is deteriorating to unacceptable levels, the proponent will correct operation procedures that are contributing to the problem and/or undertake necessary engineering installations.Item Environmental audit for the registration of existing desalination plant at Helengili Island Resort, Kaafu Atoll, Maldives(2011-09) CDE ConsultingThe purpose of this Environmental Audit report is to fulfill the requirements to get necessary environmental clearance from the Environmental Protection Agency to carry out the registration of the desalination plant at Helengili Island Resort, Kaafu Atoll.

The environmental impacts associated with this project include, increased noise levels, impingement and entrainment of marine organisms during seawater intake, impact on marine environment due to brine discharge, waste management hazards related to chemicals handling and disposal and beneficial impact of preserving the groundwater. There are indirect impacts associated with consumption of energy for desalination. Power generation has the potential to degrade air quality and contributes to global warming. In addition, fuel handling related to power generation is a potential risk for ground water and soil contamination from fuel spills and leaks. A number of mitigation measures are already in place. Facilities are located in the best area taking into account guest accommodation, staff accommodation and other guest areas. Desalination plant house building is elevated above ground level and attenuated to reduce noise level. Seawater intake is appropriately location and although brine discharge is just within the lagoon at half metre from shoreline. Seawater intake is appropriately designed to prevent/minimize entrainment of marine species. In order to protect the environment from potential fuel spills, proper pipelines are established and fuel storage is in bunded areas. The desalination system is in compliance with Desalination Regulation of Maldives. Source water is from the deep sea. Sedimentation tank is appropriately sized and located. The desalination plant house is located to minimize aesthetic impact. Capacity of desalination system exceeds the demand for water. Brine discharge is within the lagoon and location marine assessment indicates no further investigations needed. Desalination plant house includes channel ways for drainage and is kept clean and tidy with clear pathways. Chemicals are organized with proper labeling. Operation manuals are available and easily accessible. The structural integrity of the facilities are considered good. However, product water indicates presence of total coliform with the probable cause that disinfection is inadequate. One of the main recommendations of the audit is repeat product water quality tests to rule out possible causes. In the event repeat samples show contamination, necessary steps should be taken. Environmental management plan is provided particularly for desalination units, product water quality, fire prevention, chemicals handling and waste management. A monitoring plan is proposed to observe any changes taking place due to the operation of desalination plant. In the event that monitoring indicates that any environmental quality is deteriorating to unacceptable levels, the proponent will correct operation procedures that are contributing to the problem and/or undertake necessary engineering installations.
