Government environmental standards have increased specifications for stormwater systems. Oil leaking from vehicles and manufacturing facilities can cause hydrocarbons to contaminate rivers, groundwater and soil. Drains in parking garages, vehicle-maintenance facilities and manufacturing plants collect water runoff that may contain oil or sediment. Oil interceptors filter the water and store the oil and sediment.

Business owners install oil separators to prevent environmental pollution and avoid costly fines.

How our oil interceptor works

As the water enters our tank, a baffle plate reduces the flow and turbulence so that oils rise to the surface of the water. Our tank collects oil and sediment and then stores it for later disposal. Clean water passes through to the stormwater/sewer system.

Xerxes oil interceptors

Our oil interceptors are designed for maximum performance in capturing and storing harmful liquids and solids, including hydrocarbon oils. We make our interceptors from durable, non-corrosive fiberglass to keep the environment safe.  The smooth, cylindrical shape of our tanks allows for easier cleaning and removal of oil and sediment sludge.
