Comparison of investment costs in concrete and stainless steel construction at drinking water treatment plant

Turkey is an environmentally developing country and we are going to build increasing number of treatment plants. Finding space for those treatment plants which will supply water by gravity, is becoming a challenging issue. The fact that areas with high elevations are forest land or wooded areas make it necessary to destroy these lands for the construction of drinking water treatment plants which are a compulsory for civilized living. In addition, drinking water treatment plants cover a large area where hydraulic losses increase and extra excavation becomes a must. The construction and mechanical costs of reinforced concrete and stainless steel constructions were compared in the thesis study. Coagulation and flocculation unit distribution structure, settling and filter units of the treatment plants of 10,000 m3 / day, 40,000 m3 / day, 200,000 m3 / day and 350,000 m3 / day capacity treatment plants are designed as reinforced concrete and stainless steel units. Then construction and mechanical equipment costs construction and mechanical costs are compared according to 2017 unit prices. As a result of the study, it has been seen that the total construction and mechanical cost of stainless steel construction structures is reduced compared to that of reinforced concrete structures.
