Pinguicula moranensis is a perennial rosette-forming insectivorous herb in the flowering plant family Lentibulariaceae. It is native to El Salvador, Guatemala, Honduras and Mexico. A species of butterwort, it forms summer rosettes of flat, succulent leaves up to 10 centimeters (4 in) long, which are covered in mucilaginous (sticky) glands that attract, trap, and digest arthropod prey. Nutrients derived from the prey are used to supplement the nutrient-poor substrate that the plant grows in. In the winter the plant forms a non-carnivorous rosette of small, fleshy leaves that conserves energy while food and moisture supplies are low. Single pink, purple, or violet flowers appear twice a year on upright stalks up to 25 centimeters long.

Water supply and sanitation in Mexico is characterized by achievements and challenges. Among the achievements is a significant increase in access to piped water supply in urban areas as well as in rural areas between 1990 and 2010. Additionally, a strong nationwide increase in access to improved sanitation was observed in the same period. Other achievements include the existence of a functioning national system to finance water and sanitation infrastructure with a National Water Commission as its apex institution; and the existence of a few well-performing utilities such as Aguas y Drenaje de Monterrey.

The Chapultepec aqueduct was built to provide potable water to Tenochtitlan, now known as Mexico City. Tenochtitlan was the capital of the Triple Aztec Alliance empire. This fresh water was transported from the Chapultepec springs. Two aqueducts following the same route from the springs were built by the Aztecs during the 15th century, the first destroyed by flooding and the second by the Spanish. After the Spanish conquest a colonial aqueduct was built, the ruins of which are located near Metro Sevilla.
Greater Mexico City, a metropolitan area with more than 19 million inhabitants including Mexico's capital with about 9 million inhabitants, faces tremendous water challenges. These include groundwater overexploitation, land subsidence, the risk of major flooding, the impacts of increasing urbanization, poor water quality, inefficient water use, a low share of wastewater treatment, health concerns about the reuse of wastewater in agriculture, and limited cost recovery. Overcoming these challenges is complicated by fragmented responsibilities for water management in Greater Mexico City:
