Project Description

EBRD intends to support the Gabes Wastewater Treatment Plant Project under its PPP Preparation Window. Currently the sanitation system’s coverage in the Grand Gabes region of Tunisia is approximately 90 per cent. The sanitation system is connected to an Existing WWTP  built in 1995 that  does not meet the minimum technical, social and environmental requirements; and its capacity and efficiency has not kept pace with the expansion of the governorate of Gabes.

In order to improve the quality of sanitation services for the inhabitants and protect the environment of the region, a new wastewater treatment and reuse system is proposed in line with Sanitation Master Plan of Gabes published by National Sanitation Office (ONAS) in 2017. The Master Plan includes a strategic objective of 100% reuse of treated wastewater for agriculture and/ or industry which is consistent with Tunisia’s National Water Resources Strategy for 2030. The Project proposed by plan is to rehabilitate, reconfigure and extend the existing wastewater collection and transfer network and develop two new WWTPs in the north and south of the Wadi Gabes bypass channel i.e. the North Gabes WWTP and South Gabes WWTP, as a PPP. (Project)

The ONAS, which was setup in 1974, is a financially independent public body overseen by the Ministry of Environment. It is responsible for collecting and treating wastewater by developing and operating sanitation infrastructure. Since 1997, ONAS started developing and operating the sanitation infrastructure with the involvement of private sector by outsourcing services for three to five years under public procurement regulations. With the implementation of acts relating to the PPP contract, there is a further impetus to leverage private sector expertise and resources for developing infrastructure projects under the PPP model including this Project.

The Project aims to improve sanitation services in the Gabes region as well as overcome water availability and quality issues in the city of Gabes and its surrounding areas. It is also expected to encourage reutilisation of treated wastewater from the Project for agriculture and industrial purposes.

Access to Information Policy (AIP)

The AIP sets out how the EBRD discloses information and consults with its stakeholders so as to promote better awareness and understanding of its strategies, policies and operations following its entry into force on 1 January 2020. Please visit the Access to Information Policy page to find out what information is available from the EBRD website.

Independent Project Accountability Mechanism (IPAM)

If efforts to address environmental, social or public disclosure concerns with the Client or the Bank are unsuccessful (e.g. through the Client’s Project-level grievance mechanism or through direct engagement with Bank management), individuals and organisations may seek to address their concerns through the EBRD’s Independent Project Accountability Mechanism (IPAM).

IPAM independently reviews Project issues that are believed to have caused (or to be likely to cause) harm. The purpose of the Mechanism is: to support dialogue between Project stakeholders to resolve environmental, social and public disclosure issues; to determine whether the Bank has complied with its Environmental and Social Policy or Project-specific provisions of its Access to Information Policy; and where applicable, to address any existing non-compliance with these policies, while preventing future non-compliance by the Bank.

Please visit the Independent Project Accountability Mechanism webpage to find out more about IPAM and its mandate; how to submit a Request for review; or contact IPAM  via email to get guidance and more information on IPAM and how to submit a request.
