可持续的水资源管理依赖于控制运营成本的能力，而运营成本又依赖于对影响这一能力的因素的工作知识。利用国际水和卫生公用事业基准网络（IBNET）在线数据库的数据，研究了水厂的水量对运营成本的影响。对阿尔巴尼亚、摩尔多瓦、巴西、赞比亚、哈萨克斯坦和俄罗斯的供水设施进行了计量经济模型估计。评估提供了相似的定量结果和相同的定性结果。结果表明，预期运营成本相对于水量是无弹性的，运营成本的可变性随着水量的增加而增加。这些发现的含义是：(1)目前世界范围内促进节水的战略可能需要增加供水的预期单位成本；(2)作为短期成本效率激励的政策可能需要认识到在现有产出水平上降低预期运营成本的困难，如果通过扩大产量来追求效率，公用事业管理人员可能会面临控制成本的额外困难。
Sustainable water management relies on the ability to control operating cost which relies in turn on a working knowledge of factors which can affect this ability. The impact of water volume on operating cost is investigated for water utilities using data from the International Benchmarking Network for Water and Sanitation Utilities (IBNET) online database. Econometric models are estimated for water utilities located in Albania, Moldova, Brazil, Zambia, Kazakhstan, and Russia. Estimations provide similar quantitative findings and identical qualitative findings across locales. Results suggest that expected operating cost is inelastic with respect to water volume and that operating cost variability increases with water volume. Implications of these findings are that (1) current world-wide strategies to promote water conservation may necessitate an increase in the expected per unit cost of water supply and (2) policies framed as incentives for short-run cost efficiency may need to recognize the difficulty of reducing expected operating cost at existing output levels and that utility managers may face added difficulty in controlling cost if efficiency is pursued by expanding volume.
