Konya Sets Example with Sustainable Network

Konya Metropolitan Municipality continues to lead the way in Turkey with the Purple Network project, which strengthens an eco-friendly and sustainable urban development approach.

Konya Metropolitan Mayor Uğur İbrahim Altay stated that, thanks to the Purple Network implemented by KOSKİ General Directorate as a model for Türkiye, they have so far reclaimed 2,719,301 cubic meters of wastewater.

Highlighting that this recovery equals the same amount of savings in drinking and utility water, Mayor Altay said, “With the Purple Network, the first of its kind in Turkey and now recognized in global literature, we are reusing wastewater as a resource. Thanks to the Purple Network, which stands out as an innovative and eco-friendly practice, we reclaim an average of 210,000 cubic meters of water annually. This corresponds to about 17,000 cubic meters of water per month at a time when water scarcity is a pressing issue.”

The Purple Network enables the reuse of treated wastewater by processing it through coagulation, pre-chlorination, sand filtration, UV disinfection, and final chlorination stages.

The water obtained from the system, which has a capacity of 150 cubic meters per hour, is used to irrigate nearly 2.8 million square meters of green space through a 23-kilometer-long network. The irrigation is carried out by the Konya Metropolitan Municipality Department of Parks and Gardens teams.

The system, whose construction began in Konya in 2011 and was commissioned in 2012 as the first of its kind to enter global literature, had received support after being ranked first among 550 projects in the 2009 project call of the Mevlana Development Agency.
