    crucial to allocating scarce resources to hardware and management While using an asset management framework for centralized wastewater system management has become common in some countries asset management has not been used in the decentralized field One of the main barriers to using asset management in the decentralized field has been information about the reliability of decentralized wastewater treatment systems and their components Understanding the performance of the elements of decentralized wastewater systems and having the capacity to evaluate that performance against engineering ecological public health and socioeconomic goals will help realize the use of asset management to evaluate the effects of different management approaches on performance and to choose the least cost way of meeting performance goals Developing a framework though which a practitioner may select appropriate asset management and reliability assessment tools and then understanding the tools available to practitioners represent the critical elements of this project A handbook will be developed to allow for the results of this work to be easily incorporated into the decision making of communities regulators and the design community A list of future research needs data needs and potential additional useful tools will be incorporated into the handbook as well The research

    research Test centers and demonstration projects have been and continue to be initiated throughout the country without a comprehensive assessment and national consensus regarding how much and what quality of data is necessary for decision making regarding what constitutes a proven technology At the same time states and provinces are remaking their entire rules into more performance based approaches The growing environmental focus in on site wastewater is causing a shift in emphasis from the traditional disposal aspect to more of the treatment aspect in rule revisions The onsite wastewater program arena is rich with many existing data sources including test center testing organizations university test facilities vendor sampling state county local monitoring and other sources However the program is lacking the assembly of valid quality data into unified sets needed to confirm statistical trends and relationships Understanding these statistical relationships will optimize field testing protocols reduce unnecessary and costly testing help predict field performance levels and allow for more uniform acceptance of new technology by States Counties and Local onsite oversight and implementing agencies This project will develop these statistical relationships provide a decision support system that integrates test center and field data to correctly predict field performance and

    01 45 DESCRIPTION In the context of on site decentralized wastewater treatment systems a cluster system consists of two or more individual residences or other facilities that have a common collection network and place of re use or re use dispersal at or near the point of wastewater generation This project will create a manual on the Evaluation of Approaches to Planning and Management of Cluster Wastewater Collection and Treatment Systems The objective of this Cluster Manual is to help overcome existing barriers to widespread implementation by presenting factual information on how cluster systems can be planned and implemented including case studies and examples of cluster system successes and unmet challenges Examples of techniques that can both realize synergies with existing regional infrastructure planning efforts and streamline the path to optimized sustainable community wide comprehensive plans will be provided The project will address Methodologies for determining existing wastewater needs and future decentralized wastewater capacity Management and institutional issues constraints Viable technologies and technology options The project will focus on cluster system development for the following types of cluster systems Small cluster systems under 2 000 gpd Medium cluster systems 2 000 10 000 gpd Large cluster systems 10 000 50

    WU HT 01 34 DESCRIPTION The feasibility of a decentralized wastewater treatment plant in the former Hunters Point Naval Shipyard redevelopment area intended to supply effluent to a storm water treatment wetland during the dry months and to satisfy other recycled water needs of the area will be studied The study will be conducted by a consultant and managed by the Public Utilities Commission in cooperation with community and environmental groups represented by the Alliance for a Clean Waterfront Oversight and review will be provided by the San Francisco Public Utilities Commission s technical review committee which includes academic experts in alternative treatment technologies including George Tchobanoglous and David Jenkins The project will begin with the solicitation of public input Projected wastewater flows and recycled water demands will be quantified and characterized Issues concerning siting of the plant and treatment technology will be identified and addressed and a cost benefit analysis will be completed Detailed explanations of the technical aspects of the approach will be provided and the financial regulatory management and community concerns and their roles in the evaluation of alternatives will be described It is anticipated that this work will serve as a template for future work to
