Technical Advisory Services for the Arta Irrigation Network Upgrade

Consortis, leveraging its extensive experience in the maturation and design of complex land reclamation projects, was engaged by the Ministry of Infrastructure and Transport to provide technical consultancy services regarding the development of studies related to irrigation networks within the Arta plain. 

The contract entails the execution of a large-scale initiative spanning 20 irrigation zones, collectively covering an area of 16,200 hectares. Through its expertise in hydraulic engineering, geotechnical analysis, environmental permitting processes (including Natura 2000 areas), and operational management of associated authorities, Consortis demonstrates both reliability and advanced sectoral knowledge.

The Problem

The central Arta plain, encompassing 19,100 hectares, is regarded as one of Greece’s most productive agricultural regions, supporting the cultivation of citrus fruits, kiwifruit, olives, and livestock farming. The irrigation network, in operation since 1937, has experienced significant efficiency decline and currently operates at only 30% capacity. For every cubic meter of water delivered to crops, an estimated 2.5 cubic meters is lost, substantially exceeding the statutory limit of 10%.

Technical consultancy services and preparatory studies were undertaken to address a complex framework, reviewing numerous studies and projects spanning from 1990 to 2024. Within this scope, deficiencies were identified, design parameters were reevaluated, and an implementation strategy was developed with consideration for environmental legislation, Natura 2000 requirements, ongoing Public Power Corporation (PPC) projects, and the needs of local authorities.

The Solution

Consortis provided comprehensive technical documentation encompassing the physical, hydrological, geological, and socio-economic parameters of the plain, completing the project in two distinct phases. The report included:

• Complete agroeconomic assessment.
• Prioritizing zones based on weighted evaluation criteria.
• Cost estimation of projects and studies for each of the 20 zones.
• Proposal to group projects into five distinct phases to optimize economic efficiency.

An updated water supply strategy has been implemented: the utilization of the Louros River for zones 12–20 has been deemed feasible, ensuring a steady summer flow of approximately 10 m³/sec without the need for artificial regulation. This method decreases reliance on unfinished PPC projects in "Pournari II" area and accelerates the initiation of construction activities.

Benefits

The project adopts a holistic methodology, providing a strategic framework for rural redevelopment in the Arta Regional Unit. By implementing the outlined initiatives, the anticipated results are as follows:

• Annual local agricultural revenue is expected to rise from approximately €33 million to €54 million.
• It is anticipated that irrigation will extend to 16,000 hectares, thereby supporting efforts to maintain population levels within the region.
• Investment and opportunities for certified production are expected to increase.
• Additional potential includes integrating photovoltaic systems at pumping stations to reduce operational costs and conducting specialized studies on the introduction of new crop types.

Consortis demonstrates expertise in managing technical, legal, environmental, and financial dimensions of intricate projects. Its ability to provide precise, up-to-date, and practical documentation establishes its reputation as a leading technical consultant.
