Lawrence Water Transmission Main MS22-003 HDR (ArcGIS Hub)

Lawrence Water Transmission Main MS22-0035 The City has proactively performed condition assessment and collected operation and maintenance (O&M) data on the transmission main system since at least 2008. The project is aimed at planning and executing condition assessments to extending the useful life of assets as well as developing future condition assessments and/or rehabilitation recommendations for 14-inch and larger water transmission mains in the Operation Areas of “Central Service” and “West Hills”. GOAL: This HUB is for data review and communication for model prioritization and inspection results for the transmission main project. Process and Approach Iterative The first step in the process is to create a prioritization model that is iterated as data is created, reviewed and collected. This includes an initial first draft based on existing data, a second draft after review, and subsequent drafts as condition assessment or field inspection data is collected. Risk Model The risk model is an essential process for prioritization. Selected criteria factors such as deterioration or impacts to service, utilizes data to assess individual pipe risk for comparison across the targeted 30 miles of metallic mains. These factors and scoring are iterated across the project with various review to produce an established risk priority. Decision Logic To aid in prioritization for condition assessment, inspection or renewal selections a decision logic tree is produced. Mains are assessed according to each criteria decision points (diamond boxes). The Logic helps in providing a starting point as well as consistent and defensible decisions applied to each transmission line. The logic is separated into specific paths with the emphasis on renewal or inspections. Assessment Options Various assessment and renewal options are available for transmission mains. Some methods include external inspections such as field corrosion investigations used to identify high deterioration areas within the system. Other internal methods are utilized to provide individual pipe condition information to aid in planning for cost-effective operational and maintenance and renewal program.
