ARSESP RESOLUTION 469, FEBRUARY 3, 2014

It approves, on an emergency basis, the implementation of Sabesp’s Consumption Reduction Incentive Program. Its purpose is to grant a 30% reduction in water and sewage tariffs to the users served by the Cantareira System who reduce their monthly consumption by 20% during the term of the Program.

The Executive Board of the State Sanitation and Energy Regulatory Agency – Arsesp,

Considering that, in accordance to Official Letter P – 0048/2014, of January 31, 2014 and the respective attachment, submitted by SABESP: a) In 2013, only 1,090 millimeters of rainfall were recorded in the four reservoirs that compose the Cantareira System, against a historical annual average of 1,566 millimeters; b) December 2013 had the lowest average rainfall since measurements began 84 years ago and temperatures were 5% above the average, increasing consumption. c) The Cantareira reservoir, which is the main water supply for The Greater São Paulo, serving 9.3 million people, has reached its lowest level in the last ten years; d) It is necessary to recover the Cantareira System’s capacity in order to normalize water supply conditions;
