Global population growth and rapid economic development, along with modern goals for creating sustainable communities, render it necessary to focus on fundamental, finite resources such as water and energy. The interdependencies between water and energy are well known, while recently the interest of the scientific and policy communities on their dependency relationship has grown noticeably. On the one hand, water is used throughout the energy industry, while, on the other hand, the water system needs energy for collecting, pumping, supplying and treating water. Considering the latter case, great importance should be given when specifically referring to groundwater resources for the abstraction of which a large amount of energy is generally required. Therefore, minimizing the energy consumed for pumping groundwater is extremely important, and, for this reason, a large number of studies have been conducted in order to address this certain issue. However, most of the studies dealing with pumping cost minimization problems ignore the effect of friction losses on the total energy consumed for pumping and transporting groundwater. Under this perspective, the present paper attempts to highlight the importance of including friction losses in such type of problems by combining a simulation model and an optimization algorithm. Through the formulation of different setups of the same problem, that is the energy cost minimization for pumping groundwater from a system of wells and transporting it through transmission lines, it was found that only when including friction losses in the optimization problem, all managed wells are being used for pumping water, thus resulting in more reasonable and workable solutions.

全球人口增长和经济快速发展，以及创建可持续社区的现代目标，使得有必要关注基本的、有限的资源，例如水和能源。众所周知，水和能源之间的相互依赖关系，而最近科学界和政策界对其依赖关系的兴趣明显增加。一方面，整个能源行业都在使用水，另一方面，水系统需要能源来收集、抽水、供应和处理水。考虑到后一种情况，在具体提及地下水资源时，应给予高度重视，而地下水资源的开采通常需要大量的能源。因此，最大限度地减少抽取地下水所消耗的能源非常重要，而且，出于这个原因，已经进行了大量研究以解决这个特定问题。然而，大多数处理抽取成本最小化问题的研究都忽略了摩擦损失对抽取和输送地下水所消耗的总能量的影响。在这个观点下，本文试图通过结合仿真模型和优化算法来强调在此类问题中包含摩擦损失的重要性。通过对同一问题的不同设置的制定，即从井系统抽取地下水并通过输电线路输送的能源成本最小化，发现只有在优化问题中包括摩擦损失时，所有管理的井都是用于抽水，
