    Environmental audit for registration of desalination plant at Mirihi Island Resort, South Ari Atoll
    (2011-05) CDE Consulting
    The 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 project involves environmental auditing of the existing desalination plant in Mirihi Island Resort for registration of the desalination plant. Desalination system involves one desalination plant with a total capacity of 100 tonnes per day and two water storage tanks with a capacity of 180 tonnes and 88 tonnes approximately. The seawater intake is located on the southeastern side of the island with a length of 12 m from the shoreline. The brine discharge point is located at the western side of the island at a distance of 5.8 m from the shoreline. 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. However, live coral cover in the brine discharge area was found to relatively low compared to the ambient environment, which cannot be concluded as the cause for low level of coral cover. 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 conducted is interpreted as a false result as the available conditions and data does not correlate with resultant due to some sort of analysis error. Mitigation measures that are in place to reduce the environmental impacts associated with the operation of the facility include appropriate distance of brine and sweater 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.

    Environmental audit for registration of the existing desalination plant at Kaafu Funadhoo Isalnd, Kaafu Atoll, Maldives
    (2011-10) CDE Consulting
    The purpose of this Environmental Audit report is to fulfill the requirements to get necessary environmental clearance from the Environmental Protection Agency (EPA) to carry out the registration of the desalination plant at Kaafu Funadhoo. The project involves auditing of the existing desalination plant in Kaafu Funadhoo. Desalination system involves one (01) plant with a total capacity of 50 m3 per day. There is one (01) water storage tank with the capacity of 500 metric tons. The seawater intake is located on the South West (SW) of the island with a length of approximately 145 m from the shoreline. The brine discharge point is located West South West (WSW) side if the island extending a length of approximately 0.1 m from the shoreline and into the lagoon region. The facility is under operation from the year 2002. 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. Facility is located considerably the best spot accounting to the lack of land and space. Desalination plant house building is elevated above ground level and attenuated to reduce noise level. Seawater intake and brine discharge are appropriately located from shoreline. Seawater intake is appropriately designed with a copper foot valve at the uptake end. 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 at appropriate, location marine assessment indicates no or less proliferation of biodiversity that needs further investigating. 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 is considered good. 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.

    Environmental audit for registration of the existing powerhouse and desalination plant at Vilu Reef Beach And Spa Resort, South Nilandhe Atoll
    (2011-05) CDE Consulting
    The purpose of this Environmental Audit report is to fulfill the requirements of the Environmental Protection Agency to carry out the registration of the desalination plant at Vilu Reef Beach and Spa Resort, Dhaalu atoll, Maldives. The project involves the existing powerhouse and the desalination plant in Vilu Reef. The power generation system involves a powerhouse building that houses four diesel fired generator sets with total capacity of 2815 KVA and a fuel storage facility with total capacity of 103,155 litres. Desalination system involves three plants with a total capacity of 991 m3 per day and three water storage tanks. The structural integrity of the facilities is considered good. The main environmental impacts associated with this project include, increased noise levels and other emissions, potential risk for groundwater 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. Marine water quality tests identify no increase in salinity due to discharge of brine. 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. Visual observation identifies no notable damage to existing vegetation around the powerhouse building and no indication of any fuel spills around the powerhouse area. Also there is no significant vegetation in and around the vicinity of powerhouse. Groundwater quality tests are insufficient to draw conclusions. Product water quality shows inadequate level of disinfection and needs to be investigated further. 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.
