Termez State University (TerSU) implements sustainable groundwater extraction and management practices through regulated artesian wells, water-metering systems, controlled distribution infrastructure, groundwater recharge facilities and water-efficient irrigation technologies.
The university's activities are governed by its Water Reuse and Sustainable Water Management Policy and Water Conservation Programme, covering its five campus sites, including the Darband Field Training and Research Station.
1. Regulated Groundwater Extraction
TerSU operates four artesian wells supplying groundwater for landscape irrigation, household operations and technical purposes.
Special groundwater-use permit issued through the Surkhandarya Hydrogeological Station, providing a regulatory basis for groundwater abstraction.
Its water extraction and distribution infrastructure includes:

|
Total rainwater storage capacity |
143 m³ |
|
Groundwater recharge pits |
5 |
|
Combined recharge capacity |
47 m³ |
Groundwater abstraction is monitored through water meters, monthly readings and technical inspections.
The six water towers and three operational reservoirs support controlled water distribution and pressure regulation, helping prevent unnecessary losses.
2. Measured Reduction in Groundwater Extraction (2022-2025)
|
Indicator |
Measured result |
|
Annual groundwater abstraction, 2022 |
94,000 m³ |
|
Annual groundwater abstraction, 2025 |
42,280 m³ |
|
Reduction compared with 2022 |
51,720 m³ |
|
Percentage reduction |
55.0% |
The reduction reflects the university's combined water-conservation programme, including monitored abstraction, efficient irrigation, water reuse, infrastructure maintenance and demand management.
Monthly groundwater abstraction measurements were recorded throughout 2025, with the highest monthly volume in July (4,160 m³) and the lowest in February (2,870 m³).
3. Groundwater Recharge and Alternative Water Sources
TerSU operates five groundwater recharge pits with a combined infiltration capacity of 47 m³.
The recharge infrastructure is distributed across the following sites:

7 m³ |
|

47 m³ |
These systems facilitate rainwater infiltration, reduce surface runoff and contribute to groundwater replenishment.
The university also operates three dedicated rainwater storage tanks with a combined capacity of 143 m³, providing alternative water supplies for irrigation and technical purposes.
4. Water-Efficient Irrigation and Reduced Extraction Demand
TerSU applies water-efficient irrigation technologies to reduce demand for extracted groundwater.
In 2025,
|
Technology |
Implementation |
|
Drip irrigation |
1.8 hectares |
|
Controlled sprinkler irrigation |
2.4 hectares |
|
Total water-efficient irrigation coverage |
4.2 hectares |
|
Water-efficient sprinkler devices |
286 units |
Drip irrigation delivers water directly to plant root zones, reducing evaporation and surface runoff.
Controlled sprinklers provide more uniform water distribution, while irrigation is scheduled primarily during early morning and evening hours to minimise evaporation.
The reuse of 36,700 m³ of treated wastewater and 7,800 m³ of harvested rainwater in 2025. These alternative supplies reduce dependence on groundwater extraction for approved non-potable purposes.
