Introduction

  • Background
  • 2012. ONEE 100 MLD SWRO (ABG awarded)

Later, MAPM wanted 150 MLD SWRO

  • ABG joint both parts to create a single plant instead
  • f two, creating synergies: marine intake, stand-by

equipment, etc.

  • Final Plant Capacity : 275.000 m3/day

150.000 m3/day of drinking water 125.000 m3/day of irrigation water

  • Up to 400.000 m3/day in the future, which has

already been considered in the current design

200.000 m3/day of drinking water 200.000 m3/day of irrigation water
