So long as water is sold at the present low rates, building owners will see no need to install greywater treatment systems, director of the Consumption Management Office at the National Water and Wastewater Engineering Company said.
“Negotiations are underway with the Engineering Council of Iran to encourage builders to install such equipment. But the talks have not produced the desired results largely because the gadgets are costly,” Ali Seyedzadeh was quoted as saying by ISNA.
Seyedzadeh believes that the aversion to greywater recycling systems cannot be overcome unless builders are provided loans.
The concept has not become law in Iran as yet and that is why a subsidy program for households wanting to install greywater reuse systems should be initiated, he said. In Tokyo, greywater recycling is mandatory for buildings since 1997.
