根据马萨诸塞州环境保护部（MADEP）关于遵守地表水处理法规的命令，马萨诸塞州加德纳市选择了一种创新的处理方案和一种替代的交付方法来应对这一挑战。膜和臭氧是两种处理技术，随着工艺性能的不断完善、设备成本的下降，以及客户和监管机构对具有多种微生物屏障的优质水的需求，这两种技术在美国饮用水处理中得到了广泛接受。该行业的另一个增长趋势是使用替代项目交付方法，如设计/建造/运营（DBO），因为这些方法具有独特的优势。本文介绍了加德纳如何有效地利用州政府- 先进的处理技术和DBO项目交付，以加快进度向客户提供最高质量的水和服务，同时将项目交付的风险转移给DBO承包商。包括表格，数字。

Under orders from the Massachusetts Department of Environmental Protection (MADEP) to comply with surface water treatment regulations, the City of Gardner,Massachusetts selected both an innovative treatment scheme, and an alternativedelivery approach to meet this challenge. Membranes and ozone are two treatmenttechnologies that are gaining widespread acceptance in the United States fordrinking water treatment as process performance continues to be refined,equipment costs are falling, and customers and regulators demand higher qualitywater with multiple microbial barriers. Another growing trend in the industry isthe use of alternative project delivery approaches, such as design/build/operate(DBO), because of the unique advantages these approaches offer. This paperpresents how Gardner effectively employed state-of-the-art treatment technologiesand DBO project delivery to bring the highest quality water and service tocustomers on an accelerated schedule, while shifting the risks of the projectdelivery to the DBO contractor.
