California Odha Zertuche Díaz

California Odha Zertuche Díaz (1923–1991) was a Mexican civil engineer and is credited as the primary developer of the drinking water and sewerage system in Ensenada, Mexico.

[1] She is cited as the first woman to graduate from the UNAM School of Engineering,[2] in 1954, with a thesis titled Project of sewerage of the Ensenada population.

Zertuche Díaz worked in the Secretariat of Hydraulic Resources[4] where she became the main developer for the installation of Ensenada's water infrastructure.

The municipality has four bodies of water, which contribute to the drinking water: the Hidden Lagoon, the Emilio López Zamora Dam fed by the Valle Verde stream, the Hanson lagoon, located within the Constitution Park of 1857 and La Lagunita, north of the Ciprés military air base.

For each woman, a portrait and a small biography are displayed on a wall of the la Sala de Mujeres Forjadoras room in the Legislative Power building of the State Congress.
