| Abstract | ||||
| This research amid to obtain identify the effect of low-quality water (gray water) (reused water after its nomination in the special filtration stations) on the performance analysis of the turf irrigation system. The Experiment was carried out at ELRhap site, the area under investigation was 450 m², it was divided into 6 plots, and the geometrical has 5 m × 15 m. Investigated variables were gray water and tap water plots were; have been while the investigated parameter was the percentage of the applied amounts of irrigation water with a percent of 100%; 85%; 75%. The response of plant growth landscaping parameters due to irrigation water types were color, length, density and its coverage on the after heads, the effect of gray water and fresh water on the turf irrigation system was compared through the study of (uniformity, Surface roughness, Clogging ratio, flow, pressure), of sprinklers during same the irrigation period. Results of the applied could be summarized as followed. The Accumulative clogging ratio by using gray water was (1.50 – 1.56 – 1.6) % and tap water was (1.22 – 1.25 – 1.28) % at (100% - 85% - 75%) of quantity the water required for the plant. Illustrates in tap water turf quality rate was (8.50 – 8.00 – 8.00) for color, very good quality rate was (8.00 – 8.00 – 7.50) for density also very good ground cover quality rate was (8.00 – 7.50 -7.50). Meanwhile, illustrates in gray water turf quality rate was (8.50 – 8.50 – 8.00) for color, very good quality rate was (8.50 – 8.00 – 8.00) for density also very good ground cover quality rate was (8.00 – 8.00 – 7.50) at (100% - 85% - 75%) of quantity the water required for the plant. Surface roughness in the main irrigation lines was measured after the use of gray water and tap water. The erosion was (17.93– 65.35) Mm and the sediments were (15.48 – 58.22) Mm in gray while the erosion of tap water was (10.45– 34.89) Mm and the sediments were (9.06– 45.22) Mm. | ||||
