• Abstract:

  The Grajau Supply Sector is linked to the South Business Unit (MS), and is supplied by the Guarapiranga Supply System. The average volume available (DV) per billed connection in the period from February 2017 to March 2018 was 20.95 m3 per billed connection.

  The total number of connections in the sector is 144,192, with a population of 343,945 inhabitants and an unbilled water rate of 47.54%, or an Annual Lost Volume (VPA) of 18,174,536,000 liters of water per year.

  This was the scenario at the end of 2017, when we received a visit from the Business Unit's senior management and the perspectives in the best scenarios were to maintain losses at this level, or invest to change levels and create a rupture, really making it count. worth investing to earn in Lost Volume (VP).

  Therefore, it was possible to structure a project and demonstrate how hydraulic modeling, combined with good sectorization proposals, can not only achieve excellent results, but also safely anticipate the values ​​that must be achieved after the execution of the works, thus serving as a benchmark. for the effectiveness of the proposed solutions.
