For this paper, a computer program was designed and developed to calculate which
turbines could be placed in a water distribution system considering the hydraulic constraints. The
aforementioned turbines are placed in locations where we have unused hydraulic energy, i.e., when
this energy is dissipated by a regulating valve. In our case, what we do is place a turbine to make
use of that excess energy. Once the data has been entered into the program, it provides the type or
types of turbines that can be placed in each location, what power these turbines would be, and how
much they would generate annually. The program offers us two calculation options. In the first, and
simpler, one, it would be done using the net head at the location where the turbine is to be placed.
For this option, it would only be necessary to introduce the flow rate, the net head, and the hours
that the turbine will be in operation to perform the calculation. The second option would be in the
case where we did not have the net head, and, instead, we had the gross head. In this case, we have
to calculate the head losses. Normally, this would be the most used option because there are usually
no pressure drops. To perform the calculation, in this case, it is necessary to know, apart from what is
mentioned in the first option, the characteristics of the pipe (diameter, length, and material).
