Termez State University (TerSU) implements a university-wide water reuse measurement and monitoring system under its Water Reuse and Sustainable Water Management Policy. The system records water volumes collected, treated, transferred and reused for approved non-potable purposes across the university's five campus sites.
The programme is coordinated through institutional water meters, monthly monitoring records, treated-wastewater transfer documentation, reservoir inspections, irrigation records and digital water-management systems.
1. Measured Water Reuse Results (2025)

Treated wastewater constituted approximately 82.5% of total recycled water, while collected rainwater represented 17.5%.
Water Recycling Rate = (44,500 m³ ÷ 86,780 m³) × 100 = 51.3%.
2. Monthly Measurement and Water Reuse Monitoring
TerSU records recycled-water use on a monthly basis to monitor seasonal changes, irrigation demand and the contribution of alternative water sources.

The highest monthly recycled-water volume was recorded in July (6,000 m³), followed by August (5,900 m³) and June (5,600 m³).
This seasonal pattern reflects increased demand for recycled water during warmer months, particularly for campus landscape irrigation and green-area maintenance.
3. University-Wide Measurement Infrastructure
The monitoring programme covers the Rectorate Campus, Main Campus, Northern Campus, Western Campus and Darband Field Training and Research Station.
The university operates the following infrastructure supporting water collection, measurement and reuse:
|

|
Rainwater storage reservoirs |

|
Combined rainwater storage capacity |
143 m³ |
|
Groundwater recharge pits |

Combined infiltration capacity |
47 m³ |
|
Controlled sprinkler irrigation devices |
286 |
|
Drip irrigation coverage |
1.8 hectares |
|
Sprinkler irrigation coverage |
2.4 hectares |
Rainwater is collected through roof gutters, downpipes and drainage channels and transferred into dedicated storage facilities. Treated wastewater is supplied through approved treatment and transfer arrangements.
Recycled water is used for landscape irrigation, green-area maintenance, outdoor cleaning, dust control and selected technical operations. It is kept separate from water intended for drinking, food preparation and other potable uses.
4. Institutional Recording, Verification and Reporting
TerSU's water reuse measurement system includes:
- Monthly water-meter readings: Recording freshwater and recycled-water consumption.
- Treated-wastewater transfer records: Documenting volumes transferred for approved reuse.
- Rainwater collection records: Recording collected and reused rainwater volumes.
- Storage and irrigation monitoring: Reviewing reservoirs, distribution infrastructure and recycled-water applications.
- Digital records: Maintaining electronic monitoring information and water-management statistics.
- Annual reporting: Consolidating monthly measurements into the institutional water recycling assessment.
The university publishes water-management information through its official Water Management Portal at https://water.tersu.uz/.
