Sizing
OI-ST, OI-500, OI-600, OI-700, and WO-500 Series interceptors are sized by flow
rate. For indoor areas, the flow rate can be calculated by adding the maximum
flows from potential water sources, usually wall hydrants or interior hose bibs. For
outdoor areas exposed to rainfall, flow rates should be derived from the square
footage of the area served, and local rainfall rates.
In applications such as a manufacturing environment where a significant volume of
oil is expected, the storage tank holding capacity should also be considered.

Placement and Installation
Install oil interceptors in an accessible location, downstream from drains or other
fixtures receiving oily waste. In areas where the waste stream contains a significant
amount of grit or debris, an appropriate sediment/solids interceptor should be
installed prior to the oil interceptor.
OI-ST, OI-500, OI-600, OI-700, and WO-500 Series interceptors can be installed
on the floor or recessed in a minimum 4" concrete slab. Recessed installations may
require an extension to meet the below grade piping (see Extensions).
A gravity draw-off connection is located on the inside of interceptors with integral
storage tanks, or on the side of interceptors with companion storage tanks.
