Measures were taken to reduce water consumption, such as: > Installing flow regulators. These fittings for taps and showers re- place the traditional mesh filter and reduce flow by more than 50%, thus saving water. Flow regulators add air into the water, thus pro- ducing millions of microbubbles. This helps reduce water flow by half, without loss of volume. As a result, it feels as though we are using the same amount of water, at the same pressure; > Installing efficient flushes, fitted with water discharge levels; > Regularly controlling the effluent of the Wastewater Treatment Plant to decrease sanitation fees; 50
