A water drainage pit that eliminates the hard work associated with installing traditional alternative systems has been introduced by plastics innovator RELN.

The Uni-Pit inline drainage system features a vortex interior design engineered to clear unwanted surface water fast from tiled and paved areas around houses, apartments and commercial and industrial buildings.

In addition to clearing water hazards quickly — and having a flush-fitting, non-tripping grate — the Uni-Pit eliminates breeding grounds for mosquitos because it does not allow water to lie in the pit and become stagnant.

The Uni-Pit clears water quickly from the middle of the bottom of the pit, rather than being piped from the side of conventional pits, which still allows water to become trapped in the bottom below the pipe join, leaving water for mosquitoes to breed in.

The easily installed pit fits directly into the stormwater line with PVC glue, eliminating the need for extensive excavations required for traditional pits, as well as the need to cut and fix pipes to the sides.

Made from 100 per cent recycled plastic, the inline drainage system also eliminates the need for risers to the pits because the vertical pipe connecting to the stormwater line can be cut to the required depth.

The flush-fitting grate on the system - which is designed not to catch shoe heels - is available in a black concave version for use under taps and downpipes. It comes in a range of colours, including aluminium, terracotta, Green and sandstone.

Uni-Pit is available in three sizes: Series 200, which is compatible with 230 mm x 230 mm tiles and pavers; Series 300 (343 mm x 343 mm); and Series 450 (567 mm x 567 mm). A cast iron heavy duty civil grate is available with the series 300, and larger sizes are available with Class A and C galvanised grates for driveways, which can accommodate 1 tonne to 15 tonnes.

All Uni-Pit grates have a built-in anti-tamper feature.
