The ecotube™ effluent filter improves the efficiency of your septic tank or wastewater treatment plant in two ways.

It prevents the occurrence of septic tank outlet blockages and extends the life of the disposal area by filtering out solids.

Septic tank effluent typically separates into three layers. The ecotube™ extracts and filters the effluent from the relatively clean middle layer for discharge to the disposal area further minimising blockages.

You can download the ecotube™ Septic Tank Effluent Filter brochure below for more information.

When you choose an EMS product you are joining the growing number of people who also care – so thank-you – and be sure that will do all we can to provide you with first class advice born from experience, excellent value for money (because we manufacture locally), professional installation (because it is what we do), and ongoing 24/7 support when you need us.
