Geothermal energy is the best natural, renewable resource through which wastewater can be treated and reused, serving many lives. This study discusses a proposed plan using geothermal energy to treat wastewater in the ORC system. Primary geothermal resources are waterrelated, with a temperature above 120 °C. In UAE, examined the areas through the magnetic survey in Al Ain and Ras AlKhaimah with 120 °C temperature in water samples collected from 3km depth from which 1000 megawatts of electricity can be produced to give off the supply to many residential houses. The temperature rises to 150 °C as we move deeper than 3 km underground. The same sources can be extracted through the planning system and utilized for wastewater treatment. Production well distributed the geo-fluid into a fraction that generates desiccant flow for dryer and remaining feed a small-scale ORC system. The installation of an auxiliary boiler is managed in the absence of a geothermal system. However, electricity is produced from the ORC system, used to supply wastewater to a treatment plant, and pumps the geo-fluid possible with a higher temperature than 150 °C. A thermal dryer and drying processes are used, and a global energy efficiency test is done. Inlet and outlet temperatures were managed, with 5 and 10 °C differences. The efficiency and economic status of the thermal and electric systems were observed and compared briefly in this study. The moisture removal of the sludge is above 90% in the design, as the outlet water content of the sludge is less than 10%. It reduces the mass of sludge by about 73.2%. In the Organic Rankine cycle, 150kW of electricity can be produced that will be used to pump geofluid in the drying section of the sludge and wastewater treatment plant. This can be an excellent alternative for energy efficiency and greenhouse gas reduction from wastewater treatment plants in the UAE.
