Underground rainwater tank Carat – effective water management

The Carat underground tank with a capacity of 6500 liters and MAX extension is a solution for those looking for a reliable rainwater harvesting system. It is ideal for both single-family homes and commercial properties, allowing for efficient use of rainwater for watering the garden, washing the car or flushing toilets. The tank's construction is designed for durability and resistance to loads, allowing installation in areas exposed to pedestrian and vehicular traffic (when using an appropriate cover).

Construction and application

The Carat tank is made of durable high-density polyethylene (HDPE), which guarantees its tightness and resistance to corrosion. The MAX extension allows for flexible connection of connections and provides easy access to the inside of the tank for service purposes. The ability to rotate the extension makes it easier to optimally adapt the connections to the existing infrastructure. This tank is perfect for rainwater retention systems, reducing the load on the municipal sewage system and contributing to environmental protection.
