Silts are deposited and collected within the channels for removal using normal maintenance techniques and hydrocarbons are bio-degraded aerobically within the channel. When arranged appropriately, Permachannel provides a source control water treatment component that is much more effective and sustainable than conventional silt/oil separators
Permachannel is a combined surface water run-off collection, silt/effluent interception and treatment system. Each channel of the water management system incorporates a gravity separation device ahead of the outlet to prevent silt and oils from progressing beyond the channel into the rest of the drainage system.
