Livestock production in San Andrés is subsistence, there are 2,223 pigs, in 205 farms. This technology generates serious contamination problems. The results of the dimensioning a biodigester are presented, with the BioDigestor© software, from swine manure, with the objective of observing the technical-economic feasibility for the implementation of this technology. The capacity of the biodigester allows the processing of 12.31 t/d of manure, generating 276 MWh/year of electrical energy through the operation of a generator engine that works with biogas. The dimensioning of the biodigester included the calculation of the volume of the feed tank, biodigester, discharge tank, biogas storage, sludge drying bed, collection and conduction systems, heating and biogas utilization. An economic study was carried out which allowed to conclude on the viability of the project. The total cost of the digester amounts to 723,986,263 COP, which is equivalent to 21,925 COP/kW installed.
