Input data for ENERWAT-GLOB - Water Treatment

Input data for the 5 arcmin modelling framework calculating the global energy consumption of water treatment technologies (conventional drinking water treatment, desalination, wastewater treatment). Contains the following: 1) global data (folder "global_data"); and 2) inputs related to the various analyzed technologies (folder "water_treatment").

Folder "global_data" contains: 1) 5 arcmin maps of world countries, HydroBASINS, population (total, rural, urban) and Gross Domestic Product; 2) country-level Total Gross Domestic Product and population statistics reported by the United Nations; 3) validation data, i.e. country-level energy consumption data from the U.S. Energy Information Administration for 2015 (primary energy and electricity), country-level estimates of energy consumption from Liu et al. (2016) and validation data compiled from literature reviewed by Chini et al. (2021). 

Folder "water_treatment": 1) folder "desalination" contains DesalData v2019 (edited to show bare country and region information as it is licensed data) and points used to model the increasing energy efficiency of Reserve Osmosis over time (Elimelech et al. (2011) as actual model input and Liu et al. (2016) for validation); 2) folder "dwt" contains data for conventional drinking water treatment in 2015, i.e. 5 arcmin municipal water withdrawals from PCR-GLOBWB 2 (Sutanudjaja et al. 2018) calculated by Wada et al. (2014), 5 arcmin water withdrawal sources modelled by PCR-GLOBWB 2, desalination plants online in 2015 with drinking water purposes from DesalData (edited as above), water access statistics from AQUASTAT (basic water access) and the World Bank (safely managed water access); 3) folder "wwt" contains data for wastewater treatment, i.e. global wastewater treatment plants from HydroWASTE (Ehalt Macedo et al. 2022) supplemented with data on Chinese wastewater treatment plants from Chen et al. (2019), 5 arcmin wastewater production and treatment rates from Jones et al. (2021) and data on energy consumption of 328 secondary wastewater treatment plants from Longo et al. (2016).
