No, We bring all the water & electricity that we need. We carry enough water to wash 4 to 10 vehicles. The water is Deionized, Ultrapure Water from our filtration system in our garage. As far as electricity we use a quite inverter style 3200 watt generator. This gives us the 30 amps of electricity needed to run all of our equipment. The only thing that we need is the dirty vehicle and a place to clean it at.
