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.

Solar water pumping system may be a competitive application for remote and luxurious areas where power costs a lot. One may argue that solar photovoltaic water pumping systems not only comprises an environmentally friendly solution, but also contributes substantially to the satisfaction of remote communities’ water consumption needs. Therefore, the study aimed to manage pump for sprinkler irrigation system operated by solar power in small area of turf. The required hydraulic experiment and measurements were conducted using Direct-coupled photovoltaic pumping system to operating sprinkler irrigation network at the experimental farm of soil and water Research Department, Nuclear Research Center, located at Inshas, Sharkia Governorate, Atomic Energy Authority, Egypt. The essential idea to operate the sprinkler irrigation system and fulfill the water needs of turf area was to use a locally assembled pump-set to match the photovoltaic generator unsteady output. Results indicated that, solar radiation increased during summer (April and July), so the electric power, pump discharge, pressure head, Hydraulic horsepower (hp) and Photovoltaic conversion efficiency are affected as solar radiation changed.    Four mathematical equations has been derived to illustrate the relationship between solar radiation and electric power, pump discharge  pressure head , water hp and Photovoltaic conversion efficiency (PVCE) during the day hours.
