Abstract

This study investigates the variation patterns of monthly wastewater inflow data collected from the active treatment plants in Kuwait for a time period from 1999 to 2009. An attempt to examine the relation with seasonal population variation is achieved indirectly by correlating monthly-total inflow data with climatological parameters of monthly-average temperature and -total rainfall. The periodograms of the inflow, temperature and rainfall data are also determined. The results reveal two significant periodicities of 6 and 12 months. The reason for the existence of these periodicities is explained rationally and a time series model is developed which can be used to set a management plan securing nonconventional water supply for the country. Keywords: water scarcity; nonconventional supply; periodogram; sinusoidal model.
