• Abstract:

  Distilled water is an extremely important input for the production

  of medicines in the pharmacy of the Health Sciences Center (CCS) at the Federal

  University of Rio de Janeiro - UFRJ, as well as in its research laboratories, given the

  use of 100 distillers that are installed in the CCS building. However, to meet the demand

  for distilled water, these devices dispose of a large amount of water that is used for heat

  exchange. With the efficiency data of each distiller, a potential waste of 1,000,000 liters

  of water per month was estimated. But, a physicochemical and biological analysis of

  the water used by these equipments found its potability according to Annex XX of the

  Consolidation Ordinance No. 05 of Oct / 2017. This waste has been around 50 years

  since the installation of the first distiller in a research laboratory at CCS. However, in

  the present 21st century, when there is a shortage of drinking water in many places

  on the planet, this wastefulness could no longer be tolerated. Thus, the present paper

  reports the effort to contain this “waste”, reduce water consumption and the cost of

  this consumption in the CCS building, which has 120,000 m². The results prove the

  great environmental value of the project by reusing the water discarded by distillers,

  its simplicity and ability to be replicated in other universities, as well as the economic

  return.
