automatic zero discharge - closed loop wash water recovery system. The units remove all physical particles twenty microns and larger in size as well as absorbing petroleum hydrocarbons. It collects the wash water using a Vacuboom system, filters the water and returns the clean water to the main water tank. Water recovery units are in compliance with current wastewater regulations and requirements. GPC also utilizes graffiti removers depending on the surface to be cleaned. All removers are biodegradable and non- hazardous. The removers will clean the graffiti without causing damage to the underlying surface. The media used for soda blasting is baking soda. Baking soda is FDA approved, non- toxic, and contains no free silica. It is also non- sparking, non - flammable, non - hazardous, and environmentally safe. Proper clean-up and disposal is performed at each site. Natural surfaces that are repeatedly tagged may require the application of an anti - graffiti coating. These projects will be performed on a case by case basis under the City's direction. Equipment to be provided daily within contract GPC trucks for the City of Santa Ana will be a mix of new or late model long bed heavy duty pick -ups. All tricks are fully equipped and self - contained for all aspects of graffiti removal. Graffiti locations often require multiple techniques of hot water cleaning, chemical removal, and painting. Therefore, each of our trucks are equipped with 3,000 psi 5gprn hot water pressure washers, water tanks, water recovery units, .75 -gpm gas powered airless paint sprayers, ladder, baking soda blaster attachments, and pressure washer hose reels. CPC's equipment is of the highest quality and all the trucks are specifically customized and designed for GPC graffiti removal techniques. GPC currently has all the equipment needed to fulfill this contract. Mounted on the trucks are dual strobe lights and arrow sticks. The tricks possess a "Men Working" flag sign as well as enough cones to comply with WATCH handbook requirements. Inside the trucks are caution tape, respirators, first aid kits, MSDS sheets, safety equipment, and tools for repairs. All GPC trucks for the City will always be fully equipped for all types of graffiti removal as stated above. There will be no need or delay for additional equipment. GPC has immediate access to a bucket truck; however the need in Santa Ana for a bucket truck has been virtually non- existent.
