1995年，科罗拉多州柯林斯堡的士兵峡谷过滤厂加入了安全饮用水项目伙伴关系，是美国第16家获得美国环境保护局局长认可证书的工厂。然而，自1989年以来，污水处理厂的优化一直在进行中。当时，员工和管理人员都认识到了提高工厂绩效的必要性。优化涉及工厂改进的建设、工厂员工的升级、工厂管理结构的变化，以及管理人员和员工态度和理念的变化。本文记录了这些变化，并试图展示已经取得的进步。

In 1995, the Soldier Canyon Filter Plant in Fort Collins, Colorado, joined the Partnership for Safe Drinking Water program and was only the 16th facility in the nation to receive the Director's Certificate of Recognition from the US Environmental Protection Agency. However, optimization of the treatment plant has been an on-going process since 1989. At that time, the need to improve the plant's performance was recognized by the staff and the administrators. The optimization has involved the construction of improvements to the plant, upgrading of the plant staff, changes in the plant management structure, and changes in the attitude and philosophy of the administrators and staff. This paper documents those changes and attempts to show the improvements that have been achieved.
