Allproof’s round drainage pit is the ideal solution for exterior surface stormwater catchment. This economic and durable pit sump is moulded from 100% recycled plastic. The pit has a cast-iron lid that has been designed to resist heels getting caught in the grate, making it “heelproof.”

With its 35% open area and 700 mm depth, this pit sump has excellent hydraulic performance and capacity. The round design avoids aligning with pavers, walls or street furniture for easier installation. An optional pit riser, easily cut to the desired height, can be added to this robust drainage pit for an extra 200 mm of depth. The riser improves the drainage pit’s total capacity and simplifies the installation process: the pits can be hunched into place, and later, the risers can be adjusted to suit the finished surface.

Features and benefits include:

• Compatible with all exterior surfaces, including pavers, tiles, concrete and asphalt.
• Makes an excellent drain for public areas such as courtyards, pavements, public spaces and corrals, as well as private residential areas like large driveways or patios.
• Can be used in conjunction with Allroof’s linear channel drainage range as a catchment and silt trap before going to the local authorities’ stormwater system.
