Poor technical condition, operation and maintenance of the irrigation system

Water erosion, discharge, uneven distribution of irrigation water, poor yields

MASSCOTE methodology

Technique and technology for irrigation based on Simultaneous Impulse Sprinkling Kit (KSID-10S)

Actions:

Mapping of the system and services depending on canals’ purpose.

Results:

Financial and economic:

economically effective, fair and sustainable water resource management.

Ecological:

integrated protection of key environmental elements, including prevention of raising ground water level and secondary soil salination as well as irrigation-induced soil erosion, etc.

Technical:

improved technical characteristics of municipal water supply to different stakeholders.

Social:

enhanced welfare of farm employees due to increased income.

Actions:

Deployment of the Simultaneous Impulse Sprinkling Kit (KSID-10S) allowing extremely uniform and simultaneous dispersion of irrigation water across all sections of arable pasture or hayfield meadow.  Water expenditure at the impulse device makes 0.05-0.3 l/sec and 0.25-2.0 l/sec in the irrigation pipeline, thus, reducing (3-4 times) the costs associated with the pipeline network installation compared to other sprinkling systems (kits). The pipeline network is built of 15-25 mm diameter pipes easy to transport and assemble in mountainous conditions.

Technical characteristics:

Operation modes: automatic and manual

Irrigated area: 10 ha

Water consumption: up to 100 m³/day

Average sprinkling (rain) intensity: 0.002-0.008 mm/min

EFFICIENCY: 99%

MOC: 98%

Watering automation level: 100%

Results:

• Ensured water supply according to crops requirements with the account of changing weather conditions and moisture deposits in active soil layer;
• Elimination of : 1) water-induced soil erosion, 2) puddling and 3) discharge run-off;
• No need for water recirculation among irrigation sections.

Lessons learnt:

Express assessment based on MASSCOTE methodology allows to improve the planning of upgrading efforts to ensure better servicing of diversified water uses requiring higher supply flexibility and cost reduction.

Recommendations:

It is necessary to widely deploy the MASSCOTE methodology of express assessment of the condition of irrigation systems and enhancing their operation.

Lessons learnt:

The advantages of impulse sprinkling irrigation were confirmed by the research efforts on other test sites of KAZNIIVKh in Jambyl Region that allowed increasing biological productivity of Golden Delicious apple variety by 10.1-36.8%, and commercial productivity – by 16.6-49.4% compared to conventional sprinkling irrigation systems.

Recommendations:

It is necessary to continue application of similar practices in foothill areas in Central Asia subject to power supply shortages.
