Resource-saving technology of operating vertical drain-age wells based on drainage water re-use in irrigated massifs


Title Resource-saving technology of operating vertical drain-age wells based on drainage water re-use in irrigated massifs
Field of application
  • Use of water resources
  • Use of land resources
  • Re-use of drainage water for irrigation
Usability of practice for adaptation to climate change Moderate
Implemented by Kazakh Scientific Research Institute of Water Economy (KazSRIWE) LLP
Used by

Country: Kazakhstan

Province: South Kazakhstan Region

District: Maktaaral District

Settlement: Zhanaauyl Rural District

Practice also applied in the following localities

Fitting wells with pipeless water-lifting device (PWD) was widely tested and used to lift water from wells in Kazakhstan, Russia, Uzbekistan, and Kyrgyzstan

Local specifics

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.

Problem solved through this practice

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

Tools used in the practice

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.
Description of the practice and its results

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.

Lessons learnt and recommendations made

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).

Brief information on the project

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.

Funding source The technology was deployed under the grant project endorsed by the MoES of Kazakhstan
