(Excerpted from the City of Fort Worth, Texas Water Guidance Document for sizing and installation of grease traps and interceptors - to see the whole document in PDF form, click here).

Where automobiles are washed (including detail shops utilizing hand-wash practices), separators shall have a minimum capacity of 1000 gallons for the first bay, with an additional 500 gallons of capacity for every other bay.

Additionally, wash racks must be constructed to eliminate or minimize the impact of run- off from rain/storm events. Minimum requirements are roofed structures with at least two walls and appropriate grading to prevent stormwater infiltration into the sanitary sewer.
An effluent sampling well is required, per specifications listed in Part 1, Section F, Subsection d.
