Results of the study showed that the HPSD [high pressure sap displacement] technology have benefited the adopters through savings generated from treating their own poles rather than buying already treated ones. The technology had other benefits like the development of manpower skills, added income to sellers of raw poles (growers and middlemen) and to the pressure cap fabricator. It was also found out that the cost of treating electric poles through HPSD technology is cheaper than the cost of treating similar size of poles through the vacuum/pressure treatment method. Moreover, the present value of the cost of using HPSD technology treated poles is less than the present value of cost of using vacuum/pressure treated poles. The HPSD technology was also found to have contributed, to some extent, in the electrification program of the government through the delivery of electric power especially to less accessible and far-flung barangays [villages]. Further, the results also showed that in the HPSD technology treatment sites, concentrations of copper and chromium in the soil were greater than those off-sites. Also, the concentrations decreased as the time elapsed after treatment increased. While pressure caps are considered leak-proof, the results of the soil and water analysis did not clearly showed that the technology is less polluting than the vacuum/pressure treatment method. The pollution mitigating capabilities of the technology depend on whether the proper procedures and mitigating practices are observed during and after treatment.
