How could you describe your Best Practice?
Water overflowing from the swimming pool and periodically drained in accordance with operational requirements and regulations, and rainwater collected from the building's roof surfaces, are directed to a water distribution point utilizing the existing natural slope of the land. The water collected at the distribution point is primarily used to feed the artificial pond. If the amount of water reaching the distribution point exceeds the pond's storage capacity, the excess water is diverted in a controlled manner to the landscape and green area irrigation system. To prevent flood risks that may occur in the artificial pond due to heavy rainfall or high-flow water inflows, a controlled flood structure has been designed at the pond outlet. Water exceeding the pond's capacity is diverted to the drainage channel through this structure, ensuring the safe and uninterrupted operation of the system.

The effectiveness of the implementation and its fulfilment of the targeted performance criteria are verified through regular monitoring and performance evaluation studies. In this context, rainwater harvesting, recovery of pond flood and drainage water, artificial pond recharge amounts, and the volume of recovered water used in landscape irrigation are periodically monitored.
Monitoring studies show that alternative water sources are being utilized effectively, pond water levels are being sustainably maintained, and the need for mains water for green area irrigation is being reduced.

Is there the potential to exploit/outscale the Best Practice?
The developed integrated rainwater harvesting, pool water recovery, and artificial pond-supported water management system has high potential for replicability and scalability thanks to its modular structure, low operating requirements, and adaptable design to different terrain conditions. The system can be applied in areas with roof surfaces and swimming pools using similar principles. The basic requirements for implementation are the availability of alternative water sources, a distribution point where water can be collected, and storage or usage areas. Scaling the system can be easily achieved by increasing rainwater harvesting areas, creating additional storage volumes, increasing pond capacity, or expanding irrigation areas. Similarly, in smaller-scale projects, the system can be implemented by downsizing or simplifying specific components.

What are the lessons learned from the implementation of your Best practice ?
It has been shown that integrating different alternative water sources (such as rainwater and pool overflow water) into a single system significantly increases water efficiency. Reusing resources traditionally considered waste or excess water offers significant potential for reducing water consumption.
The application also revealed that integrating the land topography into the design process significantly reduces energy requirements and operating costs. Gravity-based water transfer, utilizing the natural slope, provided a low-cost and reliable operating model.
It has been understood that the artificial pond can be considered not only an aesthetic landscape element but also a multi-purpose infrastructure component fulfilling water storage, balancing, and flood control functions. This approach demonstrates that nature-based solutions can be successfully integrated with engineering systems.

Have you any recommendation to add?
Continuous monitoring of water levels, storage volumes, irrigation consumption, and flood discharge amounts via sensors allows for real-time performance evaluation and rapid identification of potential inefficiencies.
To increase rainwater harvesting capacity, additional roof areas can be incorporated into the system, controlled collection of surface runoff from impermeable surfaces can be implemented, and additional storage volumes can be created. This approach will particularly strengthen the system's water supply capacity during drought periods.
To facilitate the replication of the application, it is recommended to prepare an implementation guide containing standard design criteria, operating procedures, and performance indicators. This will enable the faster and more efficient installation of similar systems in facilities of different sizes.
In the rollout process, it is important to regularly report and share the water savings and environmental benefits achieved with stakeholders. Making success indicators visible will encourage the adoption of similar applications by other facilities.
