To ensure consistency in supply of water there is the need to ensure that a main power supply is available to either continue the treatment operation or to maintain the pumping of water to storage. Depending on the nature of the water treatment works, generally the treatment process will operate with a limited power supply. The major demand for electricity is either river abstraction, borehole pumps or the high lift pumping from works to storage reservoirs.
The Lagos Mega City Water Supply Programme Draft Report dated March 2006, indicates that the use of diesel powered generators was proving to be prohibitive in costs partially due to extended use in preference to the intermittent main power supply. Natural gas generators were indicated as a preferred option with an appropriate supply close to the Iju waterworks.
To make the most cost effective option it is necessary to equate the whole distribution system to the use of power. For example, the use of a small number of large storage reservoirs may require the transfer of large volumes of water over considerable distance. The layout of strategic storage placed relative to topography may produce a more flexible overall system. The potential for power outage will be a major element in the calculation of this option.
