Rican prisons, since 2012 the statistics of the CAI La Reforma show a steady decrease in the prison population. E.2.2. Regarding drinking water 107. On August 14, 2012, Mr. Rojas Madrigal filed a writ of amparo dated August 5, 2012, 139 before the Constitutional Chamber, alleging the consumption of non-potable water and water shortages at the CAI La Reforma, which allegedly could last for several days. On September 14, 2012, the Constitutional Chamber declared the appeal admissible 140 based on reports of the National Water Laboratory of the Costa Rican Institute of Aqueducts and Sewerage (Instituto Costarricense de Acueductos y Alcantarillados, AyA) of August 19, 2010, July 12, 2011, September 6, 2011 and September 3, 2012. The Chamber concluded that the water in this prison facility “is not potable and is a high risk for the health of consumers” 141 and ordered the prison administration to take steps to ensure a continuous supply of water within three months, as well as its potability within one month. It also ordered the Deputy General Manager of the Costa Rican Institute of Aqueducts and Sewerage to coordinate with the National Water Laboratory “in order to carry out water potability tests on the prison’s water supply” and to submit a report on the matter. 142 E.2.3. Regarding access to medical care 108. On June 26, 2006, Rafael Rojas filed an incidental plea of illness with the Sentence Execution Court of the first Judicial Circuit of Alajuela, in which he reported that he had been diagnosed with diabetes in 2001, prior to being incarcerated in the CAI La Reforma. He stated that after his transfer to that prison facility in 2002, he requested a meeting with the Prison Director to request medical follow-up for this illness, but the prison was unable to provide such treatment. He also mentioned other physical ailments, such as blindness and a hernia aggravated by his work in the prison and asked to be transferred to a facility with appropriate medical care for his condition. 143 On March 27, 2007, the court declared the motion inadmissible based on the report of the prison’s medical director, and stated that there was no evidence of “negligence, neglect or arbitrariness on the part of the prison’s medical authorities that would in any way harm [Mr. Rojas’] right to life or health.” 144 109. On December 18, 2006, the Constitutional Chamber ruled on the motion of habeas corpus filed by Mr. Rojas on December 12, 2006, in which he alleged that it was impossible for him to receive medical care as an inmate at CAI La Reforma, due to the existence of maximum weekly quotas since there was only a single health care professional. He added that the Director of cellblock Area C sent him a letter asking him to withdraw the motion, to which he agreed because “he was going [to be] transferred.” 145 In view of this, the Cf.
