Comparative analysis of the cost of water supply networks in vertical and horizontal urban sectors

ABSTRACT Due to the high cost of implementing water distribution networks regarding the water supply system, studies related to the impact of this cost become essential. A significant part of this cost refers to the complexity of the network spatialization and the kinds of land use in urban areas. In the present work, the costs of implementing water supply networks in urban sectors of mainly vertical constructions are compared to those of horizontal constructions. For the design of the networks, the EPANET computer model was used, following the necessary discharge and pressure conditions. The costs were based on the National System of the Civil Construction Cost and Index Research. It was observed that the cost of the network implemented in urban vertical areas was 13.4% higher than the one in horizontal areas, but that, at the same time, it supplied water for a number of inhabitants 13 times higher than in horizontal areas.
