ENERWAT-GLOB - Outputs

Output of the modelling framework concerning the global energy consumption of the water supply (ENERWAT-GLOB). Source code is stored at https://github.com/SustainableWaterSystems/ENERWAT-GLOB . ──────────────────────────────────────────────────────────────────────────── output_wtt - Water Treatment Technologies Reference paper: https://doi.org/10.1016/j.watres.2025.123245 Output data of the 5 arcmin modelling framework calculating the global energy consumption of water treatment technologies (conventional drinking water treatment, desalination, wastewater treatment). Contains both model output data and visualization (figures at 300 dpi). Energy consumption of desalination was calculated for 1945-2019, while energy consumption of wastewater treatment and conventional drinking water treatment was calculated for 2015. All technologies were then compared to the year 2015. Energy consumption of desalination and wastewater treatment was calculated at the plant scale, while for conventional drinking water treatment it was calculated at the catchment scale. These outputs were then aggregated to the country level. Model outputs include the following. 1) For desalination: calculated cumulative capacities and energy consumption ranges for technologies, subregions and feedwaters, in addition to plant-level and country-level energy consumption ranges and ratios, and feedwater-level energy efficiency of reverse osmosis (1962-2021). Licensed information from DesalData was removed. 2) For conventional drinking water treatment (folder "dwt"): the calculated 5 arcmin water access (safe, basic and untreated water use), the pixel-scale allocated water withdrawal sources (desalination, groundwater, surface water) and the country-level energy consumption ranges and ratios. Licensed information from DesalData for the allocation of desalinated drinking water was removed. 3) For wastewater treatment (folder "wwt"): the 5 arcmin modelled wastewater flows (from treated wastewater pixel to wastewater treatment plant pixels) and modelled offline plants, in addition to the plant-level and country-level energy consumption ranges. ──────────────────────────────────────────────────────────────────────────── output_ibwt - Inter-basin Water Transfers Submitted for publication Output data of the point-scale model calculating the energy production and consumption of inter-basin water transfer megaprojects. Contains both model output data and visualization (figures at 300 dpi). Discharge, energy production and consumption were calculated for each hydropower plant and pumping station for 33 inter-basin water transfers between 1980-2021. Model outputs include the following: 1) elevation profiles and infrastructure information for each segment (e. g. intake type, hydropower head or pumping lift, bypass length and height of tunnels and aqueducts); 2) discharge timeseries for each involved reservoir, starting from the raw discharge from PCR-GLOBWB 2 at monthly and yearly scale, which was bias-corrected and distributed to each segment; 3) estimates of monthly and yearly of energy production and its water intensity at hydropower plants, energy consumption and energy intensity of water transfer at pumping stations, and energy savings at tunnels and aqueducts, plus country-level aggregations (monthly and yearly total, with yearly percentage contribution to country-level energy production and/or consumption). ────────────────────────────────────────────────────────────────────────────本数据集为供水全球能耗（ENERWAT-GLOB）建模框架的输出成果。源代码存储于https://github.com/SustainableWaterSystems/ENERWAT-GLOB。 ──────────────────────────────────────────────────────────────────────────── output_wtt - 水处理技术（Water Treatment Technologies） 相关参考文献：https://doi.org/10.1016/j.watres.2025.123245 本数据集为5弧分分辨率建模框架的输出数据，用于核算全球水处理技术（常规饮用水处理、海水淡化、污水处理）的能耗。包含模型输出数据与可视化成果（分辨率为300 dpi的图片）。其中海水淡化能耗核算时段为1945-2019年，污水处理与常规饮用水处理能耗核算基准年为2015年，所有技术的能耗均以2015年为基准进行对比。海水淡化与污水处理能耗以厂级为核算尺度，常规饮用水处理能耗则以集水区尺度为核算单位。最终所有输出结果均聚合至国家层面。 模型输出包含以下内容： 1. 海水淡化：核算了各技术、子区域与原水类型的累计产能与能耗区间，同时包含厂级与国家级能耗区间、能耗占比，以及反渗透（Reverse Osmosis）的原水级能效（1962-2021年）。已移除来自DesalData的授权信息。 2. 常规饮用水处理（文件夹“dwt”）：核算了5弧分分辨率的用水可达性数据（安全用水、基本用水与未处理用水）、像素级分配的取水来源（海水淡化、地下水、地表水），以及国家级能耗区间与占比。已移除来自DesalData的淡化饮用水分配授权信息。 3. 污水处理（文件夹“wwt”）：5弧分分辨率的模拟废水流量（从经处理废水像素至污水处理厂像素）与模拟离线水厂数据，同时包含厂级与国家级能耗区间。 ──────────────────────────────────────────────────────────────────────────── output_ibwt - 跨流域调水（Inter-basin Water Transfers） 本数据集已投稿待刊。 本数据集为点尺度模型的输出数据，用于核算跨流域调水大型工程的能源生产与消耗情况。包含模型输出数据与可视化成果（分辨率为300 dpi的图片）。针对1980-2021年间的33项跨流域调水工程，核算了各水电站与泵站的流量、能源生产与消耗数据。 模型输出包含以下内容： 1. 各分段的高程剖面与基础设施信息（例如取水类型、水电站水头或泵站扬程、隧道与渡槽的绕行长度与高度）； 2. 各涉及水库的流量时间序列，数据源自PCR-GLOBWB 2的原始月/年尺度流量，经偏差校正后分配至各分段； 3. 水电站的月/年尺度能源生产量及其水强度、泵站的调水能耗与能耗强度、隧道与渡槽的节能效果估算，以及国家级聚合数据（月/年总量，含对国家级能源生产/消耗的年度占比）。 ────────────────────────────────────────────────────────────────────────────
