This research seeks to determine and analyze the reaction to an increase in the water invoice with the aim of introducing improvements in wastewater treatments. To this end, the purification situation is analyzed and the price elasticities of demand are obtained through Ordinary Minimum Squares. The results show that there are several small noncompliant treatment plants, as well as a complex interaction among consumption, price, and income. In many cases, the results offer small or significant differences without a clear pattern. However, it highlights the number of household members as it is strongly related to consumption and price and not considering it in the elaboration or modification of the water tariff would lead to inefficiencies. A reduction in revenue has also been found due to the strong consumer reaction, so it is necessary to assess in more depth what kind of price change would be most appropriate, as well as whether such measures would be best suited to address the problem.
本研究旨在确定和分析水价上涨的反应，目的是提出改进废水处理的措施。为此，分析了净化情况，并通过普通最小二乘法获得了需求的价格弹性。结果表明，有几个小型的不合规处理厂，以及消费、价格和收入之间的复杂相互作用。在许多情况下，结果提供了较小或较大的差异，没有明显的模式。然而，它强调了家庭人数的重要性，因为它与消费和价格密切相关，如果在制定或修改水价时不考虑这一点，将会导致效率低下。由于消费者的强烈反应，收入也有所减少，因此有必要更深入地评估哪种价格变化最合适，以及这些措施是否最适合解决问题。
