- W2625961455 abstract "The majority of developing countries are currently facing a lack of renewable fresh water resources, especially in rural communities, threatening agricultural productivity. These communities’ agriculture currently depends solely on precipitation, resulting in low crop productivity and erosion of the land. The objective of this study was to analyze the San Pedro River as a water source for a communitarian irrigation project, based on water quality analysis and water demand estimation for irrigation purposes. The analysis determined that the San Pedro River could not be used as irrigation water without prior treatment, since parameters such as potassium, fecal coliforms and total suspended solids exceeded the national standards for irrigation water, presenting concentrations of 12 mg L-1, 8000 UFC 100 mL-1 and 353 mg L-1, respectively. The biological analysis revealed ABI index values between 3 and 14, determining that the river is highly contaminated. In order to treat and reduce the concentration of these parameters between 75 and 90% a horizontal sub superficial flow wetland treatment was proposed. The irrigation water demand for the 226 ha of the agricultural land of the Lumbisi Community was estimated to be of 0.05 m3 s-1 based on crop evapotranspiration and it was used as the design flow rate for the system. The proposed wetland design presents a retention time of 2.2 days and a superficial area of 9495 m2. The estimation of effluent pollutant concentration shows that the proposed treatment would allow the San Pedro River´s water to meet national standards for irrigation water except for potassium." @default.
