The costs of maintenance, repair, and replacement of transmission mains and distribution system piping that serve urban and rural areas of the United States is expected to exceed $75 billion over the next two decades to ensure that public water systems are capable of delivering safe drinking water.

Infrastructure Management Systems (IMS) have been developed to assist utilities and decision-makers in planning and resource allocation for infrastructure. In this case study, a tool for prioritizing infrastructure replacement was developed based on using Geographic Information Systems (GIS) to facilitate analysis of the water infrastructure managed by the City of Tampa Water Department (TWD).
