Siwa Oasis Development Project

Restoring the water and environmental balance of Siwa Oasis through the development of irrigation and drainage systems, rationalizing water use, and protecting agricultural land and local communities.

EGP 3 Billion

Total value of the development works

3 Phases

For developing the irrigation and drainage system

Siwa Oasis

An oasis of environmental, agricultural, and tourism importance, Siwa has faced challenges over the past decades related to rising agricultural drainage water levels, water salinity, and excessive groundwater abstraction.

5 Villages

The oasis includes five villages and their surrounding settlements.

320 km

Approximately southwest of Marsa Matrouh.

Water Balance

Improved management of water resources and drainage levels.

Project Objectives

Lowering Water Levels

Lower agricultural drainage water levels in Siwa and Bah El-Din Lakes.

Protecting Agricultural Land

Reduce the impact of rising groundwater levels and salinity on agricultural land.

Water Conservation

Achieve a balance between water abstraction rates and safe water levels.

Oasis Sustainability

Protect the oasis’s water and environmental resources for future generations.

Water Management System

Integrated solutions combining wells, irrigation networks, pumping stations, and drainage systems

Deep Water Wells

Drilling deep wells to produce freshwater and improve the utilization of available water resources.

Water Distribution Networks

Developing irrigation water distribution networks and connecting them to new water sources.

Drainage System

Conveying agricultural drainage water away from agricultural lands and areas affected by rising water levels.
