Pires, J.S. (2007), “Consumer Tariffs in Practice: The Portuguese Experience”, presentation made at the OECD Expert Meeting on Water Pricing and Financing, 14-15 November, available at www.oecd.org/water, Herrington, P. (2008), “Portuguese Proposals for Future Household Water Tariffs”, report prepared for the 2007-08 OECD Horizontal Water Programme. The share of disposable income households spend on water supply and sanitation bills ranges from 0.2% (in Korea) to above 1% (in Central European countries: the Czech Republic, Hungary and Poland). For these groups, average representative bills would represent a significant share of disposable income in Mexico and in some Eastern European countries (Hungary, Poland, and to a lesser extent, the Czech Republic).
