Approach

WaterREPEAT framework section

Step 1

Build a complete and reliable inventory of treated wastewater availability using reported data sources and AI-assisted detection.

Compile wastewater treatment plant data from national and institutional sources

Identify gaps in infrastructure coverage and missing attributes

Detect previously unreported treatment plants using AI detection and satellite-data

Estimate treatment capacity and wastewater volumes using analytical models

Step 2

Quantify where and how much water is required across different sectors which treated wastewater can satisfy.

Estimate agricultural and environmental demand using evapotranspiration datasets

Assess industrial demand using spatial and economic data

Map demand intensity and distribution across regions

Step 3

Identify where treated wastewater reuse can deliver the greatest impact.

Overlay wastewater supply with demand hotspots

Identify high-potential reuse zones and corridors

Prioritize opportunities based on impact and feasibility
