The Plonos PL-523 is a 1000-liter rainwater storage tank designed for camping and outdoor applications. This robust water storage solution offers a large capacity for extended outdoor stays, remote locations, or supplementary water storage needs with limited access to municipal water sources. Made from durable, UV-resistant polyethylene, the tank provides reliable protection against environmental influences such as sunlight and temperature fluctuations. Its cylindrical design with integrated mounting brackets allows for secure installation on stable ground surfaces or elevated platforms. The dimensions are approximately 120 cm in height and 110 cm in diameter, with an empty weight of 18 kg. The PL-523 features a threaded inlet with an integrated filter mesh to retain dirt particles, a bottom-side outlet valve with a 1-inch connection for efficient water distribution, and an overflow protection system. The opaque material prevents algae growth by blocking light while maintaining consistent water quality. Suitable for collecting and storing rainwater from roof surfaces via gutter systems, the tank can also serve as a standalone water storage unit when filled from alternative sources. Reinforced ribs on the exterior ensure structural integrity when fully filled and withstand the pressure of 1000 liters (approximately 1000 kg) of stored water. The temperature tolerance ranges from -20 °C to 60 °C, enabling use in various climatic conditions. Installation requires a level ground surface and a suitable support structure for optimal performance. The neutral color blends into outdoor environments, while the smooth interior surface facilitates cleaning maintenance. This water storage solution addresses practical requirements for sustainable water management in camping scenarios, agricultural applications, or emergency preparedness situations where reliable water access is essential.
