Details The Water Service Organization of the Department, coordinated through the Project Planning and Development Group has tasked the Montgomery Watson/Dean Ryan team to develop hydraulic models of the Departmentºs water distribution system, Hydraulic system models have been developed in the Department in the past, with various levels of detail and using a variety of programs. The Department has chosen the H2ONET software because of its ease-of-use, operation within AutoCAD, ability to exchange data with GIS, and because of its open database structure. Dean Ryan staff assisted with the following project tasks: Develop Electronic Facility Books. Various Groups within the Department have already begun setting up electronic information on major facilities. This task will work within existing Department guidelines to assist in the conversion of information from paper to electronic format, integration of information from various databases and information systems, and implementation of tools to allow web-based data retrieval of all water system facilities information. Convert Water Service Maps to GIS Format. The Department has documented procedures for the conversion of the paper Water Service Maps (WSM) to electronic (GIS) format. We will be assisting this effort first in the Pilot Study area and potentially throughout the City. The ultimate goal is for the Department to move to all-electronic data manipulation form the Pipeline Location Reports (PLRºs) through the as-builts. Water Quality Modeling. As part of the Pilot Study, the model will be set-up and calibrated for water quality constituents, as well as for hydraulics. These constituents may include what diameter of pipeline and larger will need to be included in pressure zone models to accurately model water quality. Detailed Demand Allocation Studies. As part of the model development study, we will be refining methodologies for allocating demands based on existing information. We will be working in conjunction with the Department and the Departmentºs AWWARF project in the identification of water duty factors and the evaluation of water use throughout the City. Convert Annual Flow Data Sheets to Electronic Format. The annual Flow Data Sheets will be updated and integrated to information available from the SCADA system. It will then be possible to obtain flow data for any particular region at a glance, including peak hour, annual average, maximum week, and other flow data. Develop Documentation of Models. Detailed manuals will be prepared showing how models were developed and recommended model maintenance procedures, in a step-by-step manner. In addition, standardized model reports will also be developed to enhance the presentation of typical modeling results.
