The Civil Pond-Water Tank Synergy: An Integrated Water Management Model

This section highlights RUET's unique and innovative water management system, which integrates the Civil Pond, drainage network, water tank, and groundwater recharge into a sustainable cycle. This system represents a model of integrated water resource management that demonstrates how natural and engineered systems can work together to ensure water security.

The system operates through the following cycle

Rainwater falls on campus buildings, roads, and open surfaces. Instead of being lost as runoff, this water is captured by a carefully planned drainage system that directs it into the Civil Pond. The pond, with its substantial capacity, stores this rainwater, creating a significant water reserve that reduces dependence on groundwater extraction.

From the pond, water follows two pathways. A portion naturally infiltrates through the pond bottom into the ground, recharging the local aquifer and maintaining groundwater levels. This natural infiltration is essential for groundwater sustainability, preventing depletion of this critical resource. The remainder is pumped from the pond to the overhead water tank located immediately beside it. The proximity of the tank to the pond minimizes pumping energy and ensures efficient transfer.

The tank then distributes water across the campus network, serving all academic buildings, administrative facilities, and student halls. As water is pumped from the pond to the tank, and as water naturally infiltrates from the pond into the ground, a balancing relationship is established. Pumping, combined with infiltration, maintains groundwater levels, ensuring the pond continues to receive recharge and the system remains sustainable.

The key features of this integrated system include

The strategic alignment of the Civil Pond and Water Tank creates operational efficiency and minimizes energy consumption. The planned drainage integration ensures that rainwater is effectively captured rather than lost. The pond provides huge water storage capacity, reducing vulnerability to seasonal variations and supply disruptions. Natural groundwater recharge maintains aquifer health and long-term water security. The balancing relationship between pumping and infiltration ensures a sustainable cycle. The continuous cycle ensures reliable water supply for all 7,105 campus users.

This system demonstrates RUET's commitment to innovative, sustainable water management. By integrating natural water bodies with engineered infrastructure, the university has created a resilient water supply system that reduces environmental impact while meeting community needs.
