Subject: Treated-water quality requirements for irrigation
The CEO, Al-Waha Region Development Authority
Greetings,
Further to your letter on reusing treated water from the East Waha plant for irrigation, the water must meet the tertiary-treatment requirements of the Environment Law’s regulations, with a monthly quality-monitoring plan.
With our kind regards,
Director General, Environmental Compliance
Eng. Rayan Al-Asiri
