“…These results confirm those obtained by Bourziza et al (2017) who found that high salinity in irrigation water increases the risk of dripper clogging. Also, Zhou et al (2016), and Szekut et al (2020) found in their research work that suspended solids present in the water accentuated the clogging of drippers.…”

In water stressed countries such as Morocco, the use of treated wastewater represents a strategic perspective for sustainable agricultural development. However, technological and management innovations are needed to make it feasible and effective. The main objective of this work is to evaluate the effect of irrigation with treated wastewater compared with fresh water on the growth of two ornamental plants: Rosa Sinensis hibiscus and Lantana Camara. The study also aimed to examine the impact of treated wastewater on the hydraulic performance of different irrigation systems. To carry out this study, irrigation was applied by two irrigation systems: subsurface drip irrigation and surface drip irrigation. Also, two sources of water were compared: treated wastewater from the WWTP of M'zar (tertiary treatment) and well water, each for a duration of 2 months. The results obtained showed that the treated wastewater generally promoted a better development of agronomic parameters such as height, number of branches, leaves, and flowers for both plants. The same observation was also made regarding the esthetical parameter. For the irrigation system effect, the results obtained showed a better development under the subsurface drip irrigation system; thus, the combination of treated wastewater and subsurface drip irrigation provided the best results for both plants. Regarding the hydraulic performance of the irrigation system, no risk of clogging of the distributors was observed in relation to the water quality; the uniformity coefficient and distribution uniformity remained above 90%. It can therefore be deduced that the use of treated wastewater for irrigation of green spaces should be at the heart of water resource mobilization policies. in fact, it represents an excellent alternative for promoting national water management strategies.

“…Adin and Mollie (1991) and Camp (1998) found that emitters with a shorter and wider flow path had better anti-clogging ability. Bo et al (2014) experimentally investigated the clogging of drip irrigation emitters using reclaimed water. These emitters differed simply in the depth of the flow path, which was 0.75, 0.83, 1.01, and 1.08 mm, respectively.…”

The drip irrigation process has been designed to reduce water losses, and to combine irrigation, with the supply of fertilizers. However, in drip irrigation systems, the clogging of emitters is a major problem that significantly reduces the performance of drip irrigation systems. The water used in these systems is generally loaded with suspended matter, which might cause clogging of the emitters. This work was carried out in order to evaluate the clogging rate in three different types of emitters with roughly similar flow rates, tested in an experimental drip irrigation system, using water pumped from the Sebou River. Thus, a compensating‐pressure emitter named E1 and two non‐compensating‐pressure emitters named E2 and E3 were tested. Each dripper was subjected to 112 irrigations, which lasted 397 h and were spread over a period of 2 months. To evaluate the hydraulic performance of the emitters, the following three coefficients were used to measure the effect of clogging: (i) the variation of the flow ratio (Dra), which reflects the degree of clogging; (ii) the emission uniformity coefficient (EU); and (iii) the Christiansen uniformity coefficient (CU). No emitters became completely clogged during the experiment. However, as the clogging rate increased, the average flow rates measured in some emitters at the end of the test had decreased by 89% compared to the initial flow rates. During the experiment, flow fluctuations were observed during the evolution of the clogging, which could come from a partial recovery of flow.

The International Commission on Irrigation and Drainage (ICID) organized four strategy themes in order to realize various missions of ICID: ON-FARM, SCHEMES, BASIN and KNOWLEDGE. The Working Groups (WGs) under the theme ON-FARM deal with the application of water at the farm level and the best way to use it to increase the productivity and impacts of application of irrigation water, including its quality at the farm level.After presenting a review of the recent activities of three WGs under the strategy theme ON-FARM, this report suggests the way forward and recommendations to contribute to addressing ICID's mission as follows: to foster sufficient capacity to the extent that ICID can cope with her mission in the future, it is necessary to foster young professionals (YPs) and to develop their capacity through designating a proper training centre from National Committees (NCs) with the cooperation of donor agency, e.g. UNESCO. In addition, it is important that ICID provide and develop an open international platform to involve all relevant stakeholders of water and agriculture, including the private sector.
