As shown in Table 1, in the year 20

As shown in Table 1, in the year 2006-2007, 159,210,696 KWh of energy was needed to produce 276,170,155 m3 of water from groundwater resources in Tehran, while around 18,291,450 KWh of power was needed to produce 709,266,800 m3 of water from the 4 existing treatment plants.
Therefore an investment of around US$ 1,522,767 is was needed to produce around 2.7 million cubic meters of water per day in Tehran. It is obvious that the application of water consumption management strategies and its optimization, which lead to lesser need for water production, will have a direct impact on the amount of savings and a reduction of energy required to produce and supply water, and subsequently on the costs of energy supply.
If we assume that there is a direct relation between the 19% drop in water consumption and the reduced energy needs, the application of water consumption management measures would lead to approximately 0.513 million m3 of savings in Tehran on the water produced from existing wells and treatment plants.
Consequently the water production requirements would drop to 2.187 million m3 per day.
Considering that 0.76 million m3 per day of water needed by Tehran is produced from well and the rest 1.94 million m3 from treatment plants, the 0.513 million m3 per day reduction caused from consumption management strategies would allow a considerable number of wells to be taken out of the production and distribution circuit.
