This research aims to study the application of wind turbines for wastewater treatment by coupled to water wheel. The wooden wind turbines were selected to study its performance. The number of wooden propellers are 2, 4, 6, 8 and 10. The test was performed with wind speed in the tunnel at 1, 2, 3, 4 and 5 m/s. After that the water wheel applied to increase oxygen in the water for wastewater treatment were tested with the number of water wheel 2, 3, 5 and 7. It was found that the wind speed is the same as the former tests. The distance of submerge wheel and 0, 1, 2, 3, 4 and 5 cm were also tested to get the performance of the wooden wind turbine and the water wheels. The results showed that the 6 propeller of wooden wind turbines gives the best result, the maximum coefficients at wind speed of 2-3 m/s. which are 0.0461 and 0.0612, respectively. And the appropriate number of the water wheel are 5 turbines which the distance of drowning of water wheel is 3 cm with the speed of 216.5 rpm per second.
