6.2 Water consumption x Available Outflow the water consumption of the property influences in the choice of the device to be implanted, as well as the type of the bomb and the used plumbing. It is necessary to quantify the daily consumption expense in the farm, what it can be made by means of tables or direct measurements. In the property in question, of the demonstrated example, the funny water consumption around 1.000 l/dia, that is the capacity of the reservoir for where the hydraulical sheep stresses, what it is equivalent 0,69 l/min or 0,012 l/s, outflow that is used in the sizing of the sheep, outflow to raise. The reservoir for where wheel d? water stresses has capacity of 200 liters, that it is equivalent the 0,14 l/min and 0,0024 l/s. Adding the outflows of wheel d? water and of the hydraulical sheep gets 0,014 a total outflow of l/s, the 0,78 outflow inside of l/s allowed for in agreement grant the IGAM. Is disrespected it outflow of drive of wheel d? water, therefore this will come back to be integrated to the used stream not having been toward irrigation and nor toward animal or human consumption. 6,3 Heights of Installation of the Devices the unevenness enters the capitation point and the place of installation of the hydraulical device is a considerable factor in the sizing of these devices.

To exist this unevenness and a favorable condition of captation is necessary to make slide bars in the water course (FIG. 8), or to exist a well the superior level of the device. FIGURE 9 – Slide bars in the stream of cachoeirinha. SOURCE: Proper quantity. In the Stream of the Cachoeirinha small slide bars exist, making with that the volume of available water for captation is constant. Beyond this factor, the slide bars propitiates the formation of a secondary canal, which will go to feed the sheep and wheel d? water in a bigger level of what the devices are installed.
