Operational reliability, energy efficiency, low maintenance and pressure control were some of the advantages of SABESP’s installation of the HIGRA pumping system in American\u00f3polis.<\/p>\n\n\n\n
In 2011, HIGRA installed a pumping system at the pumping station in American\u00f3polis, on the south side of S\u00e3o Paulo. Located in the upper part of the city, at the time the neighborhood accounted for 1\/3 of the number (37,449) of connections in the supply sector, out of a total of 118,900. The previous project had a high loss rate and its obsolescence made pressure control impossible. SABESP, the company responsible for supplying water and collecting and treating sewage in 365 municipalities in the state of S\u00e3o Paulo, acquired three sets of amphibious motor pumps which have been in operation since that date and fully meet the proposed demand. The project led to an increase in the EEA’s operational reliability, with the implementation of a basic reserve group, efficient control of the pumping pressure using frequency inverters and a significant reduction in losses with effective pressure control (35 to 27 mca).<\/p>\n\n\n\n
“We’ve been using the HIGRA system in American\u00f3polis for five years and to date we haven’t had any maintenance problems. HIGRA’s value proposition of generating savings, minimal noise and very low maintenance has really paid off. We have also used HIGRA systems in other locations and have seen the same performance.”<\/p>\n\n\n\n

CURRENT SCENARIO<\/p>\n\n\n\n
– Increased operational reliability of the EEA with the implementation
of a base reserve group;
– Efficient control of the pumping pressure using frequency inverters;
– Significant reduction in losses with effective pressure control
(35 to 27mca);
– Implementation of the Herminia Boo (10 mca pressure drop)
– Reduction in electricity consumption with better performance
of the equipment and reduction in the volume pumped.<\/p>\n","protected":false},"excerpt":{"rendered":"
