The Mahaweli Water Security Investment Program (MWSIP) is a comprehensive initiative undertaken by the government of Sri Lanka, specifically under the Ministry of Irrigation. The program aims to improve water security, agricultural productivity, and resilience to climate change in the dry zone regions of the country by enhancing the efficiency and reliability of irrigation systems and water resources management.

Key Components of MWSIP

1. Objective:
   • The primary goal of the MWSIP is to provide sustainable irrigation facilities by channeling water from the Mahaweli River Basin to the dry zones. This is intended to boost agricultural production, ensure water availability, and mitigate the effects of climate variability.
2. Funding and Partnership:
   • The program is funded by the Asian Development Bank (ADB) and the government of Sri Lanka. It is a part of a larger national development strategy aimed at ensuring food security and promoting rural development.
3. Project Scope:
   • Irrigation Infrastructure: The program includes the construction of new canals, reservoirs, and tunnels, as well as the rehabilitation of existing irrigation systems.
   • Water Distribution: It focuses on the equitable distribution of water resources across several districts, particularly in the Northern, North Central, Eastern, and North Western Provinces.
   • Climate Resilience: The program integrates climate change adaptation measures, ensuring that the irrigation systems are resilient to extreme weather events.
4. Major Components:
   • Upper Elahera Canal Project: One of the key projects under MWSIP, this involves the construction of a major canal system to transfer water from the Mahaweli River to the North Central Province.
   • North Western Province Canal Project: This project aims to channel water to the North Western Province to support agriculture and other needs.
   • Minipe Left Bank Canal Rehabilitation: This component focuses on enhancing the existing irrigation infrastructure in the Minipe region.

The Mahaweli Consultancy Bureau (MCB) plays a significant role in MWSIP, primarily through its expertise in environmental management. MCB is responsible for preparing and providing Initial Environmental Examinations (IEE) reports for various components of the program. These reports are essential for assessing the potential environmental impacts of the proposed infrastructure projects and for recommending mitigation measures. By ensuring that these projects comply with environmental regulations and standards, MCB contributes to the overall sustainability and success of the MWSIP.

Impact and Benefits:

• Enhanced Agricultural Productivity: The improved irrigation systems will lead to increased agricultural output in the dry zones, boosting food security.
• Water Security: The program is designed to secure water resources for agriculture, domestic use, and industry in the targeted regions.
• Rural Development: By providing reliable water supplies, MWSIP supports the economic development of rural areas, reducing poverty and improving living standards.
• Environmental Protection: The incorporation of environmental assessments and climate resilience measures ensures the sustainable management of natural resources.

In summary, the Mahaweli Water Security Investment Program is a vital initiative by the Ministry of Irrigation, aimed at transforming the water management landscape of Sri Lanka’s dry zones. The involvement of MCB in preparing environmental assessments is a key aspect of ensuring the program’s sustainability and compliance with environmental standards.
