Considering the area’s restriction, it is proposed to construct a combined (block) WWTP with reinforced concrete structures. The treated wastewater will be discharged into different parts of the Dalarik River and also the Hrazdan River, increasing the river water resources and enabling the irrigation of larger agricultural areas. However, it is important to note that allowing different discharge points would generate additional costs, as it would require a system of pipes and valves. Alternatively, all flows could be discharged in the river in one single point.
