Thankyou! Im not real sure, going to do some asking around before buying the mat. In a residential area where i would be washing at someones house, i dont think it would be a big deal, but in a business parking lot i think it would be a concern.
This is something I have been stressing out about here in Florida.
After pricing the mats... I really can't afford one yet

-I too have been scoping out businesses with large parking lots in high traffic areas hopeful to do enough basic car washes to build a client base from a 'fixed' location, but don't want the hassle of being busted for violating any laws, naturally.
However, from what I have gathered each car might account for maybe 10-15 gallons of water (max), so if 10 cars is a practical goal to shoot for, that's only 100 - 150 gallons of water per day... and IMHO trying to reclaim such a small amount is total bs!!! After all, I have pressure cleaned commercial properties using tons of water and they don't reclaim any of the water used in my experience.
Like you Ryan I am a bit concerned, as I currently have the extended van, PW, Gen, 250 gal tank, vacuum, most cleaning supplies, and planned to have a lic/ins before I touch a vehicle. Being I am just now getting the 12v pump and plumbing done this week, I was hoping to have basic lic/ins by March 1st and be rolling.
If I don't find a 'location' to jump-start the business with basic car washes, it could severely impact my future goals of offering a full mobile detailing service. Worst case scenario, I imagine they (*whomever controls the spice) would issue a warning before slapping someone with a fine... but with my luck, that wouldn't be the case.
On the generator, mine is pretty loud (*Troy-Bilt 3550 watt cont w/ B&S motor)), but I have been looking into getting a 2000 watt power inverter, a secondary marine battery (*like a 750 cold cranking amp) and a battery charger to re-charge the battery at night for a quieter operation, and less gas usage.. Another option is to boost the alternator size and run the inverter from the existing battery... but I don't really like that idea.
