经过三年的运营，showcase Foothills水处理厂满足了科罗拉多州丹佛大都会区的基本需求，其表现达到或高于预期。利用其位于城市上方的水力优势，电厂的抽水成本最低，电厂的水轮机产生的电力足以运行设施并出售多余的电力。最少的员工可以操作自动控制的流程。该设计使运营商能够根据季节性水质，选择总处理工艺或旁路混凝、絮凝和沉淀，以最大限度地降低运营和维护成本。固体干燥床利用了气候优势，进一步降低了处理成本，1986年的平均成本仅为0美元左右。 每千加仑03加仑。包括表格、数字。

After three years of operation, the showcase Foothills water treatment plant, serving the base needs of the Denver, Colorado, metropolitan area, has been performing at, or above expectations. Taking hydraulic advantage of its location above the city, the plant's pumping costs are minimal and the plant's hydro turbine generates enough power to operate the facilities and sell excess electricity. A minimum staff can operate the automatically controlled processes. The design enables operators to choose the total treatment process or bypass coagulation, flocculation and sedimentation to minimize operation and maintenance costs, depending on seasonal water quality. Solids drying beds take advantage of the climate, further lowering treatment costs, which in 1986 averaged only about $0.03 per thousand gallons. Includes tables, figures.
