Abstract
The reuse of treated wastewater for irrigation is often seen as one way of maximizing existing
water resources in cities. The aim of this study is to evaluate the applicability of treated
wastewater to grass and to evaluate the impacts of continuous use of treated water on soil and
yield. Two plots of grass irrigated with drinking water and treated wastewater were monitored
over a two-year period. The physical and chemical factors in soil and leaf tissues were analyzed.
The plants were irrigated with treated wastewater as it contained the highest sodium content.
There were no negative impacts regarding changes in soil pH but a significant increase in
electrical conductivity and sodium content was observed in wastewater irrigated soils. Treated
wastewater can be used as a resource for agricultural irrigation because it participates to
phosphorous and organic matter. However, it is necessary to take into account that many crops
can be adversely affected by irrigation with wastewater due to the sodium content and this must
be taken into account when using plants, as this is the case in this study. The benefits of
irrigation with treated urban sewage water include the contribution of plant nutrients to the grass
while preserving fresh water, where the paspalum plants were irrigated with several types of
water, namely fresh water, secondary treated wastewater and the mixture among them in a ratio
of 1: 3 for sewage and fresh water and also a mixture In a ratio of 1: 1 for fresh and sewage
water and knowing the impact of water of different quality on plants, soil and irrigation water,
through the following analyzes: 1) chemical, natural and chemical soil 2) chemical analyzes of
plant growth that affect the dry weight of the plant, where it was observed that the highest
proportion The plants irrigated with sewage water had secondary treatment.
