Resumen

HAHN-VON-HESSBERG, Christine M.; QUINTERO, Herbert E.  y  GRAJALES-QUINTERO, Alberto. DEVELOPMENT AND IMPLEMENTATION OF A MODIFIED WATERWHEEL AS A PROPOSAL FOR SUSTANTAINABLE WATER CIRCULATION FOR A FISHING STATION.. Luna Azul [online]. 2016, n.42, pp.185-199. ISSN 1909-2474.  http://dx.doi.org/10.17151/luaz.2016.42.12.

There are problems of water supply in the summer and the winter, in the Fishing Station of Universidad de Caldas (Colombia). This article shows how, by means of a water recirculation system, the Station is provided with the liquid persistently, keeping physicochemical parameters fit for fish farming. Changes in land use, such as urban development, have generated impact on the watershed that supplies the Station. Then, a proposal to reuse water through a sustainable model, adapting an ancestral mechanism surges: the Waterwheel. This work was developed in three stages: data collection, monitoring and implementation of the proposal. For the assembly adaption of part of the existing infrastructure of the Station to collect water was required. The design of the waterwheel consists of a water catchment system (cylinder with compartments) that drives a pulley system and in turn to the modified waterwheel with buckets, which capture the water (1.5 l / sec) and then raise it 7 m. The physicochemical parameters (temperature, oxygen and pH) and biological (macroinvertebrate) remained within normal ranges for a crop of tropical fish. The design developed is modular, it does not require electricity or skilled workforce for maintenance, it can be used as an alternative tool in agriculture particularly in the aquaculture sector where water difficulties arise, and it is inexpensive and environmentally sustainable .
