本文提供了一种维护市政蓄水设施的方法。该程序旨在提供制定具有成本效益的坦克维修计划所需的信息，包括坦克修复资金的最佳使用。本文简要介绍了该程序，以建立对该系统的总体理解。然而，本文的主要重点是介绍一个财务决策程序，以及如何使用它为基于最低总成本而不是最初最便宜的备选方案的决策提供合理的依据。对现有康复考虑因素进行了案例研究，以说明该系统是如何工作的。以下项目是康复计划中的重要考虑事项: 应多久对储罐进行一次评估，评估的详细程度如何；喷砂/重新喷漆的涂层是否在技术上有效且成本效益高；油箱是否需要修复或更换更具成本效益；如果储罐不符合当前标准，哪些翻新项目是强制性的；为了实现最高的成本效益，应该多久进行一次修复？这些考虑与任何规模的供水系统有关，无论是连接超过1500000个的休斯顿市，还是只有几百或几千个连接的小得多的城市。包括桌子。

This paper provides a disciplined method for maintaining municipal water storage facilities. The procedure is designed to provide information needed to develop a cost effective tank maintenance program that includes the optimum use of fundsfor tank rehabilitation. The program is briefly presented in this paper to establish a general understanding of the system. However, the primary focus of this paper is to present a financial decision procedure and how it is used to provide a rational basis for making decisions based on the lowest total cost and not just the initially least expensive alternative. Case studies of existing rehabilitation considerations are presented to illustrate how the system works. The following items are important considerations in the rehabilitation program: how frequently tanks should be evaluated and to what detail; is overcoating inlieu of blast/repaint technically effective and cost efficient; should the tank be rehabilitated or is replacement more cost effective; if a tank doesn't meet current criteria, which renovation items are mandatory; and, how often should rehabilitation be undertaken for maximum cost efficiency? These considerations are relevant to any size water system, whether it be the City of Houston with in excess of 1,500,000 connections or a much smaller city with only a few hundred or thousand connections. Includes tables.
