Tax payers finance about 55% of total water expenditure. Given the strong increases in federal budget for water supply and sanitation programmes, the federal government is currently financing close to 40% of all water expenditures that are currently tracked. State and municipal governments represent an additional 15% of water expenditures.8 Water users finance over 45% of total water expenditures through water and sanitation tariffs (MXN 27 billion from households, commercial and industrial users), water resources charges (MXN 6 billion mostly industrial users), bulk water tariffs (MXN 2.2 billion mostly from urban water users) and investments, operation and maintenance of irrigation infrastructure (MXN 4.3 billion from agricultural users).
