  1. Domestic Cold Water supply from the municipality cold water (metered)
  2. Domestic Cold Water supply from tankers with suitable TDS (quantified)
  3. On site brackish Well Water (estimated through well water pumps runtimes)
  4. Wastewater reuse from treatment plants for irrigation (metered)
  5. Rainwater reuse in some buildings (metered / estimated)
  6. Condensate drain reuse in some buildings (estimated)
