The Azerbaijan State Water Resources Agency (ASWRA), in partnership with the Ministry of Economy of Azerbaijan (MOE), has invited expressions of interest (EOIs) from private sector firms for the rehabilitation of the Hovsan Aeration Wastewater Treatment Plant (Hovsan WWTP) and the development of new wastewater recycling facilities in Hovsan, near Baku, under a PPP model. 

Located approximately 15 km east of Baku, the Hovsan WWTP is the largest wastewater treatment facility in Azerbaijan and treats a substantial share of the wastewater generated in the Greater Baku metropolitan area. The Project aims to rehabilitate and modernize the existing wastewater treatment plant and develop a new recycled water treatment facility, thereby improving wastewater treatment, expanding water reuse, and strengthening the country's water resilience as targeted by the “National Strategy for Efficient Use of Water Resources” in the country.

ASWRA and the MOE hereby invite qualified private sector companies or consortium/consortia to submit an EOI for the rehabilitation, financing, operation and maintenance of the Hovsan WWTP together with the design, construction, financing, operation and maintenance of a new recycled water treatment facility under a Design-Build-Finance-Operate-Maintain (DBFOM) scheme.

Completed EOIs must be submitted electronically no later than August 21, 2026, to ppp@economy.gov.az
