Abstract

Descriptive and quantitative statistical analysis methods were used to determine the extent of treated wastewater or non-refined water used in landscape irrigation in new cities as an alternative to drinking water utilization. The results of the study showed that about 65% of the sample, use drinking water and about 35% of the sample use treated wastewater in landscape irrigation. On other hand about 36%, 30%, 28% and 6% of the sample use sprinkler irrigation, mixed sprinkler and drip irrigation, traditional surface irrigation, and drip irrigation system in landscape irrigation, respectively. About 40% of the sample consume more than 20 cubic meters of water per week, where about 22%, 20% and 18% use more than 10-20 cubic meters, more than 5-10 cubic meters and 1 - 5 cubic meters per week to irrigate their landscape, respectively. There is a statistically significant relationship between the water quality used in landscape irrigation at home gardens and irrigation system, home garden area, and plant diversity in the garden. Whereas, the existence of a statistically significant relationship between water quality used, the number of landscape irrigation per week and the quantity of irrigation water used weekly were not proven. About 85% of the respondents prefer to use drinking water, where only 15% prefer to use treated wastewater for economic, psychological and health reasons.
