An estimate of the willingness to pay for treated wastewater for irrigation in Oman
The volume of Treated Wastewater (TW) produced in Oman is increasing, due to increased connection of houses to the sewage network and increased construction of wastewater treatment plants. Despite 68% of the TW been used for irrigating urban landscapes, 10.3 Mm3 TW has been discharged to the sea in...
