The largest sanitation company in Minas Gerais, Copasa, has chosen HIGRA products to significantly improve services at its Cataguases plant. At the site, benefits such as a 90% increase in flow rate; low maintenance costs; a reduction in noise levels; major gains in energy efficiency; the complete elimination of equipment burnout caused by floods (thanks to the HIGRA amphibious system) and a constant reduction in corrective maintenance (avoiding system stoppages that jeopardized supply to the city) are already making a difference. The first pump was installed at the beginning of 2013 and the third in March, as well as the backup equipment. “As soon as the installation was complete, the entire old system could be deactivated and the advantages could be seen in practice,” says HIGRA director Silvino Geremia, highlighting a phrase uttered by one of the Copasa workers. “He said… where’s the noise? I can’t believe it, 25 years working here and I never imagined this was possible.” <\/p>\n\n\n\n
