Your ultimate tool for the separation of silt and sand
Trusted for Safety and Reliability


Sandtraps are your ultimate tool for the separation of silt and sand from water in all wash down areas.  In fact, they’re recommended by most regional councils for all effluent collections areas.  They help to prevent sludge build-up, saving your pond from having to be cleaned out so often.  Plus, the reduction of silt and sand will extend the life of your pumping and irrigation equipment. 
For the best of the best, we recommend going for 1 piece pre-cast construction.  This means no potential leaking from joins, and a faster installation.  1 piece also means added strength and stability. Multiple soft spots provide more flexibility to position your inlets and outlets to provide maximum solids separation performance. Inlets and outlets should be offset to create greater swell movements and slowing water velocity.

In-Line Effluent Filters

In-Line Effluent Filters are designed to eliminate debris that create blockages in irrigation nozzles.  They’re really simple, with liquid flowing through the screen inside the filters body.  All you need to do is open the top of the filter, remove the filtering screen, get rid of the trapped debris, replace the cleaned screen and reassemble the filter.  A real tidy operation!
