To prevent environmental degradation and ensure full retention for forecourts, especially in areas where there is a risk of fuel or oil entering the stormwater system from service stations, truck stops, or vehicle parking areas, oil and water separator tanks are employed.

These tanks collect and separate hydrocarbons from water, allowing only EPA-approved distilled water to pass into the wastewater system. This process effectively mitigates the risk of contamination and helps maintain environmental sustainability in such high-risk areas.

The range capacity of tanks constructed from OWS 5-1320 gallons to OWS 50-13200 gallons. This wide range of capacities allows for flexibility in meeting different storage requirements across various industries and applications.
