Wadi Bandawaya is located 40 km north of Mosul city. On its path through Jabal Dehqan, a narrow valley is suitable for constructing a dam on it for the purposes of harvesting rainwater and feeding water to the valley through several springs located below the foot of Jabal Al-Qoush on the northern side of the mountain. The current study evaluated the quality of water for civil and agricultural purposes in order to complete the data for establishing water harvesting. It was found through chemical analyzes of the main cations (Ca2+, Mg2+, Na+, K+) and anions (HCO3-, SO4=, Cl-, NO3-), as well as measuring the pH, electrical conductivity (E.c.), total dissolved salts (TDS) and total hardness (TH). The valley water falls within the natural limits set by the World Health Organization for drinking purposes through the use of the water quality index (WQI) as well as its suitability for agricultural purposes according to the standards of Sodium Percentage (SSP), Sodium Adsorption Ratio, SAR, and the amount of residual sodium carbonate (Residual Sodium) Carbonate, RSC). As well as, the percentage of magnesium (MAR).
