Use of water resources

Country: Kazakhstan

Province: South Kazakhstan Region

District: Maktaaral District

Other settlement: Zhanaauyl Rural District

Country: Kazakhstan

Province: South Kazakhstan Region

District: Maktaaral District

The Maktaaral Irrigation Massif has 220 vertical drainage wells (VDW), but currently practically all of them are not operational.   The highest level of ground water occurrence in Maktaaral Irrigation Massif falls on December-February after completion of fall irrigation washings and water-charging.  The beginning of vegetation season (April-May) is characterized by receding ground water table.

The second ground water table rise occurs during mass vegetation watering of main crops, as a rule in July-August.

The vertical drainage system in Maktaaral Irrigation Massif does not operate on permanent basis, but mainly during fall and winter (irrigation washing, water charging) and during the vegetation season at the time of insufficient irrigation water supply.

Rural Water Consumer Cooperatives (RWCC) are located in the tail part of Dostyk and Turkestan Main Canals (TMC)

Deterioration of reclamation situation: raising ground water table and land salination.  Intensified water withdrawal, saving on pipes, reusing ground water for irrigation

Conflicts between water users associated with water distribution;

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

Set of measures to enhance land reclamation condition (rehabilitation of vertical drainage well capacities, fitting them with equipment for pumping ground water via casing column)

• Using casing pipes in wells for water lifting requires application of a special (pipeless water-lifting) device.

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

The pipeless water-lifting device allows fixing the submersible pump at a set depth and dividing the well’s trunk into suction and injection zones.

Water lifting is done via the casing column and not the water-lifting pipe used in traditional well operation technology.

 At the same time:

• metal consumption and total weight of the pumping installation decreases by 60-90%;
• pollution of the water-bearing layer is excluded; assembly and dismantling costs decrease by 40-70%;
• power costs of water lifting decrease by 30%; water return of the water-bearing layer increases; possibility of polluting and/or infecting the water-bearing table is excluded making the suggested technology competitive.

 This technology of pumping underground water renders the possibility of intensifying water withdrawal due to creating vacuum in the pump’s suction zone.

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.

There is a need to perform major repair of vertical drainage system with the aim of ensuring the timely diversion of drainage and waste water from the Maktaaral Irrigation Massif.

It is also necessary to identify the optimal environmental and reclamation conditions to prevent salination of irrigated massifs by way of re-using drainage water for irrigation.

The data on the chemical composition of drainage and waste water (as per reports by Southern Kazakhstan Hydro-Geological Reclamation Expedition) prove that in most cases such water can used for irrigation without the need to dilute it with clean irrigation water.

Required personnel capacity-building:

• continuous training of the staff of the Operational Section of Southern Kazakhstan branch of RSE “Kazvodkhoz” on assembly and dismantling of target equipment used for VDW re-fitting;
• drafting and disseminating training materials (operation recommendations, practical seminars and trainings).

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.

Within the framework of 5039GF/4 Project supported via the financial grant on behalf of the Ministry of Education and Science (MoES) of Kazakhstan, several demo-sites were established in Maktaaral District of Southern Kazakhstan Region to hold trainings and practical seminars for specialists and to promote the new technology of pumping underground water via vertical drainage wells re-fitted with pipeless water-lifting devices.

Observations of ground water level were performed in the irrigation massif; optimal reclamation regime for irrigated land via vertical drainage wells based on the new technology was developed.

Counterpart holds seminars, training courses and programs on effective use of water resources in Kazakhstan with the aim of assisting farmers and other land users in building up their corresponding skills as well as teaching them basic water use principles.  In the course of its collaboration with Counterpart, IWMI analyzed and studied the reclamation condition of irrigated land plots and the technical state of irrigation and drainage networks in Makhtaaral and Turkestan Districts of Southern Kazakhstan Region.
