Description

Sustainable urban systems require appropriately sized infrastructure. However, when cities face economic and population decline, hardened infrastructure - such as drinking water distribution systems – is difficult and costly to modify. This dataset provides the results of a modeling exercise performed using EPANET (Version 2.2) to examine potential scenarios for rightsizing water infrastructure in a shrinking city. The modeling was performed utilizing a full-scale, calibrated hydraulic model of the drinking water distribution system in Flint, Michigan obtained through a Memorandum of Understanding between the City of Flint and Wayne State University.

For this analysis, in addition to a base model, we evaluate six scenarios involving either only decommissioning of pipes alone or both decommissioning and downscaling replacement of pipes. Model scenarios were run for three weeks (504 hours). The first two weeks (335 hours) were used to stabilize the system. System conditions (e.g., pressure in pounds per square inch (psi) and water age (hours)) at 15,936 locations in the system were recorded every hour, resulting in 168 measurements for each location in the system, a total of 2,677,248 measurements per hour. The minimum and maximum pressure, maximum water age (95th percentile), average pressure, and average water age (50th percentile) are computed during the third week of simulation.

This dataset describes theoretical changes associated with each scenario as well as the pressure and water age resulting from EPANET modeling. Additionally, socio-economic data are also included. This dataset is paired with a second dataset available at https://doi.org/10.22237/waynestaterepo/data/1729036800/a.
