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.
