Detailed Narrative Description of Project:
The Amu Zang Irrigation System is located in Surkhandarya Province and comprises a cascade of pumping stations and the network of irrigation canals conveying water from the Amu Darya River to a command area of 96 800 ha. Water from the Amu Darya River is pumped into the canals through three main pump stations (PS) – Amu Zang I PS (5 pumps with total capacity of 125 m3/sec. and 37,6m head), Amu Zang II PS (with 8 pumps and total capacity of 125 m3/sec., H=43m) and Babatag PS (8 pumps with total capacity of 32 m3/sec and 78m head)., which form a cascade system of pumping. The system was built in 1973 and was at the end of its useful life. High sediment levels in the pumped water damaged the pumping equipment. Before the project, a large amount of sediments in canals and drains reduced their capacities and increased the operation and maintenance (O&M) costs. Due to this and high level of seepage, only about 50% of water reached farmers’ fields. If this project was not completed successfully, some of the key components of the main system could have collapsed in less than 5 years, which in turn could have devastating effects on a large number of the rural population directly dependent on the system.
The Project goal was to maintain and improve agricultural productivity and farm income on sustained basis. The Project objectives were to (i) increase the reliability, efficiency, and sustainability of the water supply of Amu Zang irrigation system; and (ii) facilitate and accelerate the ongoing agriculture sector reforms in the project area. All of these objectives are fulfilled. The Project had the following components: (i) rehabilitation of Amu Zang irrigation system (Rehabilitation / reconstruction of irrigation canals(88 km main canals, 102 km of inter-farm canals and 250 km of drainage collectors , rehabilitation and improvement of the pump stations and replacement of pumps-all 8 pumps in Babatag PS, 12 temporary pumps in Amu Zang II PS and 2 main pumps 25 m3/second each in Amu Zang I PS)): (ii) support to improve irrigation management; (iii) support to private farm development; and (iv) project management, monitoring and evaluation. The Project will also facilitate the on-going policy and institutional reforms by promoting and alternative procurement quota systems for cotton and grain and introducing water delivery fees in the project area; any by assisting the Government to develop the national cost recovery policy and improve the operational guidelines for WUA development. The achieved key project outputs are: (i) more reliable and efficient Amu Zang irrigation system that allows yield increase, (ii) enhanced management capacity for water management systems, resulting in conversation of irrigation water, and (iii) better access to agricultural inputs (farm machinery, fertilizers, seeds), together with introduction of modem farming technologies, which enhances incomes.
