Deterioration of reclamation situation: rising of ground water, land salination

DUV 2/0.005-10 Water Level Sensor

Technique and technology of land reclamation via a system of vertical drainage wells (VDW)

The DUV 2/0,005-10 Sensor was deployed and demonstrated its efficiency in Jambyl and Southern Kazakhstan Regions.  It allowed to visually and in real-time observe the dynamics of water level fluctuations and completely exclude manual operations and subjectivity in the process of taking readings – a relevant task in the environment of transition to market economy.

Water level sensors were installed in 17 hydro-posts in Southern Kazakhstan Region (Maktaaral District).  In Jambyl Region, the same sensors were installed in 3 hydro-posts in Merke District.

Results:

Technical:

a) immediate data exchange on water volume passing through every water lead to the fields of agricultural producers (farms) as well as automatic transfer of this information to stakeholder organizations (branch of “Kazvodkhoz” Republican State Enterprise (RSE), etc.);

b) archiving the data coming from hydro-posts with its subsequent processing in the form of reports.

Technical and economic:

1) “all in one” – all components of DUV 2/0.005-10 are assembled into one unit/casing, do not require any additional modules and adjustments, i.e. it is an out-of-the-box universal tool to execute monitoring of water reserves irrespective of the availability of power supply and other technical and weather conditions.  The simple Sensor’s design facilitates installation and start-up and commissioning, as well as allows minimizing labor costs;

2) DUV 2/0.005-10 is flexible in terms of installation, data transfer methods, measurement subject (water level or hydro-lock position, etc.);

3) the cost of the measuring unit is 3-4 times less compared to currently available alternatives;

4) DUV 2/0.005-10 designed architecture allows increasing the number of controlled points and performing an integrated monitoring of the whole network.

Actions:

A VDW system set up. Prior to its installation, the area was drained via a horizontal open-type drain-age network ineffective as to reducing the mass of salinized land.

Comprehensive VDW efforts significantly enhanced drainage.

However, currently due to the absence of a single organization responsible for VDW operation, maintenance and repair, the VDW systems recon-structed under World Bank and Asian Development Bank projects do not perform as effectively as ini-tially.

Results:

Financial and economic:
Increased cotton yields (from 10-15 up to 30-35 dt/ha).

Technical:
Successful response to land salination in 3 districts: ground water table steadily kept at 2-3 m depth leading to a sharp contraction of salinized land area.

Lessons learnt:

Deployment of the DUV 2/0.005-10 Water Level Sensor led to increased precision of water level and consumption measurements and higher promptness of information collection compared to any known methods.

Using the device in the conditions of water resources deficiency, on the one hand, will ensure objective accounting of water use and, on the other hand, will promote water conservation among water users which will lead to more efficient technological development of agro-industrial complex and higher labor productivity.

Recommendations:

The success of deploying water level sensors in project hydro-posts facilitated execution of measures to disseminate the positive experience of using the device in the water sector.  Their effect will be even more significant as enhanced quantity and quality indicators will ensure effective management of water resources and water conservation with simultaneous development of irrigated agriculture.

Lessons learnt:

In due time, the model proved useful and timely, as the country urgently needed to increase its cotton yields. The practice demonstrated high efficiency of VDW in combatting land salination.

Recommendations:

1. Establish a special VDW System Maintenance and Operation Department;
2. Build personnel capacity:
• Continual training of personnel in the Department and Provincial Hydrogeological and Land Reclamation Expedition;
• Drafting and distribution of training materi-als.
