The City is interested in a study answering four (4) questions: 1) what could go wrong - the hazard identification, 2) how likely it could happen - the analysis of frequency, 3) what consequences there could be - the consequences analysis, and 4) - appropriate prioritized measures for risk mitigation. The City is expecting the result of this study to be a customized evaluation of the City’s existing water system facilities and infrastructure, and a comprehensive capital infrastructure plan that outlines the prioritization and total cost of maintenance, improvements, and replacement costs for all infrastructure associated with the water system. The selected firm will be responsible for the following tasks: • Utilizing existing data and information including, but not limited to: o Asset data in Lucity o GIS data (pipe data, water main break data, etc.) o Water meter data and meter reading software o Non-Revenue water reports and leak detection data o Lead service line replacement plan o SCADA system data • Conducting a detailed assessment of the entire municipal water distribution infrastructure system, including but not limited to: o Water mains and appurtenances o Valves o Hydrants o Water services o Water towers o Ground storage reservoirs o Pumps and motors o SCADA system o Meters and meter reading system o Emergency wells o Standby generators o Building facilities o Water facility security and systems related to water distribution • Developing a calibrated distribution system hydraulic model of the distribution system in a professional water modeling package. • Evaluation of the distribution modeling of the entire water system, and plan for risk-based approach in determining distribution system improvements. • Assessing vulnerabilities and potential failure modes considering a risk-based perspective. • Quantifying the potential consequences of failures, including impacts on public health, safety, and service delivery. • Developing a risk matrix using available information to identify any hazards and to estimate the risk for individuals or population, property or the environment. • Recommending short-term (1-3 Years) and long-term (4-10 years) capital improvement projects based on the risk assessment findings. • Providing cost estimates for each recommended project. • Prioritizing recommended projects based on risk of failure.
