The 110mm Underground uPVC Square Hopper is a durable surface water collection component designed to capture and channel rainwater runoff from downpipes directly into below-ground drainage networks. Manufactured from robust, high-impact unplasticized polyvinyl chloride, this hopper is engineered to withstand outdoor weathering, UV exposure, and the demands of residential or commercial properties. Its sturdy construction ensures long-term reliability and dependable performance at ground level.
 
Featuring a wide square opening, the hopper provides a generous catchment area to receive water discharging from standard rainwater pipes while helping to minimize splashing and overflow. It serves as a crucial transitional junction between above-ground gutter systems and sub-surface pipes. The integrated outlet connects securely with standard 110mm underground drainage systems or gully adaptors, establishing a seamless and efficient flow path for surface water.
 
Designed for straightforward installation and low maintenance, the square hopper typically accommodates a removable grid or grating to catch leaves, twigs, and larger debris, protecting your underground drainage network from blockages. Whether you are installing a new surface water system or upgrading existing rainwater management around a building, this uPVC square hopper delivers professional-grade functionality and enduring peace of mind.
