There are two broad categories of marginal-quality water: wastewater generated by the domestic, commercial, and industrial sectors; and saline water from agricultural drainage systems, surface runoff, or pumped from overexploited aquifers. Millions of small-scale farmers around the world irrigate with marginal-quality water, often because they have no alternative.
