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 (heel-proof). With a 35% open area and 700mm depth it has excellent hydraulic performance and capacity. The round design avoids aligning with pavers, walls or street furniture making install a lot easier.

This robust drainage pit has the option of adding a pit riser, the riser can add up to an extra 200mm depth and be easily cut to the desired height. The riser improves the drainage pits total capacity and installation as the pits can be hunched into place easily and risers adjusted to suit the finished surface later.
