What are washdown and silt separators?

Silt doesn’t seem like much by itself, but it has the potential to cause serious problems for your drainage system. 

As the separator fills with water, the silt settles at the bottom of the tank below the invert of the pipe. When the water level reaches the outlet pipe, it leaves the separator and continues to the drainage system, leaving the silt in the tank. 

The Environment Agency requires that discharge from washdown applications must discharge to a foul drainage system.   

Example applications 

  • car washes 
  • pressure washing facilities 
  • transportation depots 
  • car dealerships 
  • truck dealerships 
  • farm equipment dealerships 

How do washdown and silt separators work? 

Step 1 

Rewatec washdown separator being installed on site

Contaminated water enters the unit where the heavier solids and silt settle to the bottom of the tank. 

Step 2 

The lighter liquids and hydrocarbons will rise to the surface and be retained within the tank. 

Step 3 

Treated water will exit the separator via the outlet.
