Water Absorption Infrastructure and Stormwater Management System

HomeWater Absorption Infrastructure and Stormwater Management System
Water Absorption Infrastructure and Stormwater Management System at Navoi State University
Navoi State University has developed an integrated stormwater management and water absorption system designed to maximize rainwater infiltration, reduce surface runoff, and improve groundwater recharge across the campus. The system combines permeable surfaces, water retention facilities, drainage infrastructure, and dedicated infiltration zones to support sustainable campus water management.

1.Permeable Pavement and Infiltration Surfaces
Apart from the green surfaces the university utilizes permeable concrete blocks, gravel surfaces, and open soil zones that allow rainwater to infiltrate naturally into the ground. More than 48,000 m² of campus surfaces are designed to facilitate water absorption rather than direct runoff, helping to reduce pressure on drainage systems during rainfall events.
2. Roof Gutter and Stormwater Collection Network
All major university buildings are equipped with roof gutter systems that collect rainwater from rooftops and direct it toward designated drainage channels, infiltration zones, and retention structures.
The roof drainage network serves as the first stage of the campus stormwater management system by capturing rainwater from building roofs; preventing uncontrolled runoff and soil erosion; directing water toward absorption areas; supporting groundwater recharge; reducing localized flooding risks during heavy rainfall.
The integration of roof gutters with campus drainage infrastructure ensures that rainfall is effectively managed and utilized through natural infiltration processes.
3. Rainwater Retention Structures and Ponds
The university maintains artificial ponds and stormwater retention facilities equipped with protective mesh systems. These structures temporarily store runoff collected from surrounding surfaces and gradually release water into the soil profile. Nowadays, university has 2 rainwater collection units.
The retention facilities increase rainwater infiltration; reduce peak stormwater discharge; support groundwater replenishment; improve overall campus water resilience.
4. Blue Signage for Water Absorption Zones
Special blue environmental signs have been installed throughout the campus to identify dedicated water absorption areas.
More than 30 designated infiltration locations are marked to raise awareness among students and staff about sustainable land management practices and the importance of preserving permeable surfaces.
5. Subsurface Drainage and Infiltration System
A network of underground drainage pipes and filtration channels operates beneath key sections of the campus.
This system serves the following purposes:
Redirects excess stormwater;
Prevents waterlogging;
Controls groundwater movement;
Enhances infiltration efficiency;
Reduces flood risks during intense rainfall events.
The drainage network works together with permeable surfaces, retention ponds, and roof gutter systems to create a comprehensive water absorption infrastructure.
Through the allocation of 87,234 m² (31%) of campus land for water absorption and stormwater management, Navoi State University significantly improves natural groundwater recharge, minimizes surface runoff, reduces erosion risks, and strengthens campus resilience to climate-related water challenges.
