María Eloisa Meléndez Altieri (born December 26, 1951) also known as Mayita, is a Puerto Rican politician who served as the mayor of the city of Ponce, Puerto Rico, from 2009 to 2021. Meléndez Altieri was elected during the Puerto Rican general elections of 2008, becoming the first woman elected to the office in Ponce's political history. She was also the first mayor of a party other than the Popular Democratic Party in Ponce since 1989, when Rafael Cordero Santiago became mayor. This is Mayita's second candidacy in politics on the island and her first electoral win. In the Puerto Rico's 2004 general election, Mayita presented her candidacy for a senatorial seat representing Puerto Rico's 5th district, but lost in her bid for the position. Meléndez Altieri lost her bid for reelection in the 2020 general elections to Luis Irizarry Pabon from the Popular Democratic Party.

Acueducto del Norte envisions bringing round-the-clock drinking water to the residents of the northern mountainous sections of the municipality. It is expected to serve communities from the easternmost community of Hogares Seguros in the northeastern Barrio of Anón to the northwestern community of Santas Pascuas in the northernmost part of Barrio Guaraguao just south of the border with Adjuntas, and from the southern community of Paraíso in Barrio Machuelo Arriba, to the municipal boundaries with Adjuntas, Utuado and Jayuya. It includes a new water purification plant in the Burenes sector of Barrio Tibes, that would be using water from Río Portugués and Río Inabón in Ponce, and from Río Jauca in the Adjuntas/Jayuya area, and will also use water from four other water purification plants on Guaraguao, Burenes (Tibes), Hogares Seguros (Anón), and Real Anón (Anón).
