Why is controlled dosing of effluent to fields better than
traditional trickle fed media beds or leach fields?
When conventional trench disposal fields are constructed it is to a
specified length. Unfiltered effluent from the septic tank is then allowed
to flow into one end of the trench until progressive or creeping failure
occurs due to large unfiltered volumes into small receiving area.
Filtered effluent distributed over an area regularly, and in measured
amounts, has far more long term viability and is less damaging to the
receiving environment than conventional methods of discharging unfiltered
effluent into trenches and hoping gravity and good luck will take care
of the rest.
