克莱顿县水务局（CCWA）拥有并运营三座地表水生产（WPP）工厂（J.W.Smith、W.J.Hooper和Freeman路），为克莱顿县提供饮用水。CH2M HILL目前正在与三家水厂签订合同，评估、设计和安装先进的消毒设施。这些工厂的产能分别为10（弗里曼路）、12（J.W.史密斯）和20 mgd（W.J.霍珀）。弗里曼路和史密斯工厂从史密斯和浅滩溪水库取水。Hooper工厂接收来自Hooper和Blalock水库的水。除W.J.Hooper WPP外，美国东南部水库的原水水质是典型的，该WPP的原水浊度变化很大。本项目的主要目标是在每个WPP安装先进的消毒设备，以提供额外的病原体保护，并遵守预期的饮用水质量法规。 提供紫外线防护的主要目的是降低紫外线防护的资本和成本。紫外线消毒的实施将基于以下五个阶段的方法:评估和筛选高级消毒的替代方案；制定方案设计和监管协调；编制招标文件和采购紫外线设备；基于所选设备的紫外线设施详细设计；以及全面设施的建设和验证。包括桌子。

Clayton County Water Authority (CCWA) owns and operates three surface water production (WPP) plants (J.W. Smith, W.J. Hooper and Freeman Rd.) that supply drinking water to Clayton County. CH2M HILL is currently under contract to evaluate, design and install advanced disinfection facilities at all three water plants. The Plants' capacities are 10 (Freeman Road), 12 (J.W. Smith) and 20 mgd (W.J. Hooper). The Freeman Road and Smith Plants receive water from the Smith and Shoal Creek Reservoirs. The Hooper Plant receives water from the Hooper and Blalock Reservoirs. Raw water quality is typical for reservoirs in the southeastern U.S. except for the W.J. Hooper WPP which is subject to wide variations in raw water turbidities. The primary objective of this project is to install advanced disinfection at each WPP to provide additional pathogen protection and to comply with anticipated drinking water quality regulations. Ultraviolet (UV) disinfection was recommended due to its lower capital and operation costs and its effectiveness in meeting the primary objective of providing additional pathogen protection. Implementation of UV disinfection will be based on the following five-phased approach: evaluate and screen alternatives for advanced disinfection; development of schematic design and regulatory coordination; preparation of bidding documents and procurement of UV equipment; detailed design of UV facilities based on the selected equipment; and, construction and validation of full scale facilities.
