      In economics, demand is not simply want or need. It is defined as the willingness to pay for a certain product. Traditional economics (by Adam Smith) also further sub-divide demand into: Absolute Demand and Effectual Demand. Absolute Demand is our desire or need for certain goods (like food, water, transportation, etc), but absolute demand does. the water and sewage bill may amount to 10% of their monthly income, which is more than the World Bank recommendation of 3% (World Bank, ). This reduces the willingness to use as well as pay. Moreover, the water charges are, at present, flat, regardless of water consump-tion and high water cost reduces willingness to use the.

      Ability to pay can also be important in determining effective demand. For example, a consumer’s demand curve may indicate at a price of £10, he is willing to buy 3 CDs. But unless he has sufficient income the demand curve remains only theoretical. Effective demand means the consumer has the ability to pay. Ability to pay and discretionary income. Safe water supply is one of the important Millennium Goals. For development of market water supply services, the willingness of consumers to pay is essential. The consumers’ willingness to pay (WTP) for piped water supply using the contingent valuation (CV) method with different starting point bids was investigated for the Pavlodar Region, Kazakhstan.
