"All along the U.S.-Mexico border, about 840,000 mostly low-income, immigrant Latinos have settled in colonias – cheap plots of land outside city limits without basic infrastructure such as water and sewage systems, electricity and paved roads."
"YUMA, Ariz. – Nestor Alaniz didn’t get a permit to build a well in his mother’s backyard, and he didn’t get it inspected.
In fact, he didn’t even know how to dig a well. He learned by watching tutorials on YouTube while his brother, a construction worker, helped him drill the 25-foot-deep hole.
They built the well after the old one dried up for the fourth time. Their mother, who lives in a “colonia” – an unincorporated community – of about 400 residents outside of Yuma, Arizona had gone without water to her home for a year."
