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

Conflicts between water users associated with water distribution;

Loss of water from canals (due to filtration and discharge)

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

• Survey among stakeholders,
• Microsoft Excel computer-based planning of water use,
• Seminars to train water users on computer-based technologies and water accounting

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.

Actions:

Based on the location of RWCCs and with the account of recommendations by akimats (local governance bodies), 8 RWCCs were selected to conduct a survey based on specially prepared questionnaires. Survey results showed that the main issues in target rural areas were water distribution among consumers and drawing up water use plans (WUP) for RWCCs. The proceeding trainings seminars focused on exactly these themes. At the end of the year, the monitoring of the introduction of new water distribution methods was conducted.

Results:

Application of this water distribution practice allowed to sharply reduce the quantity of conflict situations as well as nearly eliminate water losses due to filtration at the canals’ headworks and discharge.

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.

Lessons learnt:

Hourly water distribution allows more flexibility in the context of water deficit. After the trainings for water users and WUAs personnel on hourly water distribution, the number of corresponding conflicts decreased.

Recommendations:

Considering the high turnover of RWCC staff, the trainings should be repeated on annual basis. Hourly water distribution schemes should be used in locations/periods of acute water shortage.
