Abstract This study proposed a canal diversion surface flow constructed wetland (CWT) to treat the drainage water in Tala Drain Gharbia Governorate where Nile Rosetta Branch is its outfall. The treated will be used for irrigation purposes. treatment system consists of sedimentation pond, CWT with reed plants, and storage pond. Field data on hydraulic, climatic, influent concentrations were collected. first order P-K-C* relaxed tanks was applied design CWT. results indicated that 2400 m 3 /d discharge, BOD pond area 2600 2 (260 long 10 broad) required one-day hydraulic retention 1.0 depth. controlled by winter four parallel CWTs each one 12,480 , loading rate 0.05 m/d, period (HT) 2.76 days. balance indicates minimum maximum losses 14%, respectively, recorded January June operation discharge are 2482 2741m /d, respectively. rates elimination BOD, TN, TP, FC showed 62, 58.4, 43, 99.8%, respectively indicating good quality uses. still far from drinking standards needs purification. green wastewater region similar regions help decision-makers as primary strategic resource management ecological solution meet United Nations' Water Sustainable Development Goals.
