Pluvitec Master Blocks, together with Pluvitec® Nozzles, form the confined flow underdrain system developed by Hidro Solo and are part of the company’s portfolio of innovations for Water Treatment. These high-quality products are backed by technical studies certifying their performance and are currently installed in water treatment plant filters across dozens of locations in Brazil.
Our Blocks are injection-molded from high-impact polystyrene, while the Nozzles feature a housing molded from high-glass-fiber engineering plastic. Their unique geometry and overlapping disc design render them completely crush-proof and collapse-proof, fully eliminating the cost of early filter disassembly for repairs.
The uniformity provided by Pluvitec Blocks is the result of extensive research conducted at Hidro Solo’s laboratory. These studies determined the optimal nozzle density and introduced two calibration points: one in the backwash water inlet channel and another in each individual nozzle. This design allows custom adaptation for every project, regardless of the filter’s shape or size.
