Observed and modeled water demand variations in a city's drinking water distribution system. This dataset is not publicly accessible because: EPA cannot release the personally identifiable information regarding the water demand variations and drinking water distribution network information according to the Privacy and the Freedom of Information Act (FOIA). This data set contains information on the distribution network, which is under a signed confidential agreement for homeland security conditions. It can be accessed through the following means: Restricted access may be granted to authorized persons or organizations under a possible legal arrangement. Format: Data are stored in Excel and computer-modeling meta data. This dataset is associated with the following publication: Zhao, Y., J. Yang, Y. Shao, Y. Lee, and T. Zhang. Demand-Driven Spatiotemporal Variations of Flow Hydraulics and Water Age by Comparative Modeling Analysis of Distribution Network. JOURNAL OF WATER RESOURCES PLANNING AND MANAGEMENT.

Operational, financial, and land use data to estimate drinking water treatment cost functions for 2006 calendar year. Data are organized for surface water and groundwater systems. This dataset is not publicly accessible because: EPA cannot release personally identifiable information regarding living individuals, according to the Privacy Act and the Freedom of Information Act (FOIA). This dataset contains information about human research subjects. Because there is potential to identify individual participants and disclose personal information, either alone or in combination with other datasets, individual level data are not appropriate to post for public access. Restricted access may be granted to authorized persons by contacting the party listed. It can be accessed through the following means: US EPA's Office of Water, Office of Science and Technology, Engineering and Analysis Division is the holder of the survey data. US EPA's Office of Water maintains a database of point coordinates for surface water intakes and wells used for public water supply. Format: Our dataset is described in detail in Section 3 of the paper. We include a link to the 2006 Community Water System Survey that excludes the identifiers. Other data are confidential business information. This dataset is associated with the following publication: Price, J., and M. Heberling. The Effects of Agricultural and Urban Land Use on Drinking Water Treatment Costs: An Analysis of United States Community Water Systems. Water Economics and Policy. World Scientific Publishing Co. Pte. Ltd., 5 Toh Tuck Link, SINGAPORE, 6(4): 2050008, (2020).

The following datasets are used for the Water Rights Demand Analysis project and are formatted to be used in the calculations. The State Water Resources Control Board Division of Water Rights (Division) has developed a methodology to standardize and improve the accuracy of water diversion and use data that is used to determine water availability and inform water management and regulatory decisions. The Water Rights Demand Data Analysis Methodology (Methodology https://www.waterboards.ca.gov/drought/drought_tools_methods/demandanalysis.html ) is a series of data pre-processing steps, R Scripts, and data processing modules that identify and help address data quality issues related to both the self-reported water diversion and use data from water right holders or their agents and the Division of Water Rights electronic water rights data.
