Full Description

This paper discusses how assessing the reliability of water reclamation facilities has become a public policy debate of cost versus benefits to health protection. There are no quantifiable outcomes with which to measure success or failure, except for disease outbreaks that are identified after the fact and that may or may not be tied to these projects, or the failure of a particular process or piece of equipment. The conclusion is that public health protection is not a pure economic decision. The paper provides a document titled, "Guidance for the Preparation of Reliability Assessment for Reclaimed Water Facilities", which is intended to be a brief, concise document to be included in the facility's engineering report, and possibly as a stand-alone document produced to document conceptual changes in the design and operations approach for the facilities. It recommends including the following information in the reliability assessment: facility and treatment train description; beneficial reclaimed water quality uses and required water quality and treatment parameters; overall facility reliability concept; identification of critical compoments and equipment; expected treatment by compoments and equipment function; expected time frames for full, uninterrupted operations; critical operating conditions for the treatment system, components; component and equipment operations standards; alarm conditions responses; and, reclaimed water standards specific reliability requirements. Includes appendix.
