Yes, HYDRASEP, Inc. also offers the HYDRAPASS Bypass Basin for large area surface run-off applications such as parking lots, airport tarmacs, and equipment storage. Facilities that have a low probability of oil spills will gain the economy of design and installation when the collected oils are washed off with the first flush. The separator can be sized to handle the first flush event, and all run-off greater than that may be safely by-passed.
