Abstract

Stepwise regression procedure is used to estimate residential water demand in each house as a function of number of fitments, number of occupants, area lot price, and tap water pressure using cross-sectionally metered readings from 50 households in Basrah, Iraq, between January 1977 and February, 1978. A methodological approach is used that provides unbiased estimate of parameters and standard errors, Demand relations are estimated for total residential, summer, winter and sprinkling demands. Sprinkling use per day per customer for a year is estimated by subtracting winter consumption from summer consumption. The number of fitments per dwelling variable explained the largest proportion of the variation in the data in all demand models. Results are reported herein.
