AZPW Maintenance Services Experts Answer Your Questions:

Q. Why is pressure washing used by so many industries?

A. Pressure washing is the most efficient, cost effective cleaning method for removing stubborn stains and sterilizing hard surfaces. Hot water, under thousands pounds of pressure with the aid of powerful soaps, degreasers, paint removers and/or muriatic acid is the most widely used method for quick removal of oil, grease, automotive fluids, rust, gum and paints from hard surfaces. Since pressure washers were invented in the early 1950’s, millions of pressure washers have been solid in the U.S. Pressure washing is a very fast growing, market driven Industry. Approximately 700,000 pressure washers are sold each year. There are over 200,000 gas stations, 831,000 fast food service outlets, 126,000 grocery stores, 18,000 multi level parking garages in the United States. These are just a few of the industries that utilize pressure washing equipment and services.


Q. Why can’t you discharge your waste water to the storm drain?

A. One quart of used motor oil contaminates 250,000 gallons of fresh water! Storm drains lead straight to our nation’s waterways, the source of our drinking water. Parker West specializes in the removal of automotive fluids, oil and grease. Depending on the traffic flow and the frequency of cleaning high traffic areas, our wastestreams contain varying concentration levels of contaminants. Also, our wastestreams contain significant levels of copper, lead, cadmium, zinc and chromium, all of which are toxic to humans and aquatic life.


Q. Where are the storm drains?

A. Storm drains are usually on the sites of the properties we clean – You will notice that most paved or cement surfaces at the gas stations, parking garages/lots, fast food restaurants, etc. slope towards a hole that has a metal grate over it. That’s the storm drain. Also, storm drains are the big holes along the gutter’s of most streets. Rain water and if the wastewater generated by pressure washing, is not contained, it washes to the nearest storm drain, along with all the contaminants and soaps drains. The storm drains lead straight to the nearest waterway (creek, river, then ultimately, the ocean).


Q. Why should we clean our outdoor surfaces? The rain washes these surfaces for us.

A. You are right, when it rains, some of the pollutants are washing into the storm drains. That is one of the reasons why over 47% of our waterways are too polluted to drink, fish or play in. Outdoor, high traffic areas need to be cleaned regularly to prevent storm drain runoff pollution.

Pressure washing machines clean contaminants off of hard surfaces much more effectively than normal rainfall. For example – Some of the gas stations we clean have as many as 3,500 cars a day passing through – we clean their locations 2-4 times a year – And – some of the parking garages we clean go years without cleaning before they use our services. You can imagine the build up of contaminants. Remember, we are using hot water (210 degrees), up to 3,500 pounds of pressure per square inch, with the aid of powerful cleaning agents to scrub these surfaces. The level of contaminants in our waste stream is much higher than runoff water from normal rainfall.


Q. Where do I obtain material safety data (MSDS) Information?

A. While the label does give us some information about product hazards, it is not always complete. It is important that you read your Material Safety Data Sheet. A few tips you should know.

All hazardous materials have these specifications. Even not so hazardous materials have them. You can get information about anything from purified water to acetone and alcohols.

All manufacturers using any quantity of hazardous materials are required to create MSDS’s for their products. Sometimes you have to request these sheets, as they are not always provided willingly.

The MSDS is an expanded version of the material label including identity, hazardous ingredients, physical and chemical characteristics, physical hazards, reactivity data, health hazards, precautions for safe handling and use, and control measures.


Q. Why can’t we discharge our wastewater to the sewer without pretreatment?

A. It is illegal to discharge contaminated wastewater into the sewer without meeting Federal, State and Locally mandated pretreatment standards. If high levels of contaminants are discharged into our public owned treatment plants, it can cause them to fail to meet their own discharge requirements. The contaminants end back up in our waterways.

Our wastewater contains significant levels of contaminants that are toxic to humans and wild life. Oil, grease, automotive fluids, chromium, copper, lead, zinc and cadmium. For instance, to legally discharge our waste water, the oil and grease levels typically have to be below 100 parts per million.

Remember, there are hundreds of thousands of businesses that use pressure washers to clean their facilities. For instance, when we clean a multi-level parking structure, we generate up to 65,000 gallons of wastewater in 45 days. There are 18,000 multi level parking garages in the U.S. with 8 million spaces. One quart of used motor oil contaminates 250,000 gallons of fresh water. If we did not contain, collect and pre-treat our wastewater, we would be polluting 30 million gallons of water in 45 days! This figure is based on removing only 3-4 quarts of motor oil from the parking structure per day.


Q. We just discharge our wastewater to the landscaping. Is that O.K.?

A. It depends on what is in the waste water that you are generating. Legally, you need written permission from the owners of the property to discharge to the landscaping. Also, ground water contamination needs to be considered. (See the News Article Archive, posted 2/16/02). A gas station across the street from a school discharged their wastewater generated by pressure washing to their landscaping. The toxic cleaning agent they used, traveled across the street, under ground. The drinking water at the school is now tainted with the toxic chemicals.


Q. Who is responsible for your service provider’s wastewater discharges?

A. The person or company hiring the surface cleaning services, as well as the company performing the service, share equal responsibility to ensure the work is performed in an environmentally safe and legal manner. The surface cleaner must be in compliance with the local mandates in each city where the service is being performed. Every city municipality has it’s own rules and permitting guidelines for acceptable waste water handling and sewer disposal. If you have questions about the best management practices for proper handling and disposal of the waste water generated from a particular cleaning activity, contact you’re local city municipal waste water handling facility. Protect yourself. Ask your service provider for a copy of their written sewer discharge permit.


Q. Do we need to manifest our wastewater and have it hauled as hazardous waste if we aren’t pre-treating?

A. Only if your wastewater is considered hazardous. Most of the profiles of our untreated wastewater are classified as hazardous, due to the high level of oil, grease, automotive fluids and trace metals. If you are not pre-treating the wastewater on site of each cleaning operation, so that you can legally discharge to the on site sewer, you will be required to collect, store, manifest , haul and dispose of wastewater as hazardous waste. The law requires you to obtain a hazardous waste haulers license in each city you are hauling. The disposal cost of the untreated wastewater averages $1.00-$3.00 a gallon. PROTECT YOURSELF – If your service provider is hauling your wastewater off site, be sure to ask for a written MANIFEST so have written proof of proper disposal. Remember: The property owner, management hiring the service, as well as the service provider are all legally responsible for proper wastewater management and disposal.


Q. What does Parker West do with the contaminants that have been removed from the waste water?

A. The second most unique aspect of the patented Parker West System™ is that our treatment process separates and permanently FIXATES the contaminants in on step within minutes, which eliminates the cost and liability of hazardous waste disposal. The contaminants we remove from our waste steams will never leach back out into the environment again. Our service includes hauling the solid waste back to our shop where we decant it by 50%. Then, we dispose of it properly as a non hazardous Class II solid for approximately $70.00 a ton.


Q. What type of waste water treatment technologies are available for mobile service cleaners?

A. A variety of affordable, water processing equipment exists that is effective for specific types of cleaning applications. Multi stage filtration, ozonation, and mechanical oil water separators make it possible to comply to the local municipal sewer discharge requirements, if a pressure washer is providing services such as removing cooking grease or washing fleets of vehicles.

The Parker West System has been designed to handle more complex waste streams that contain significant levels oil, grease, automotive fluids metals and/or paints. The unique aspect of the PW System is that on site of each cleaning operation, in one step, within minutes, all the contaminants in our wastewater are immediately removed and permanently fixated, rendering a non hazard solid waste. Clean water is discharged to the on site sewer.


Q. How do you know what type of waste water from pressure washing activities needs to be collected and processed?

The wash water generated from cleaning activities that contain, cleaning agents, oil, grease, automotive fluids or paint removal should never enter into the storm drains. This wash water should always be collected, cleaned and disposed according to the guidelines set forth by the local governing agencies. Contact your local city municipal wastewater treatment facility to obtain information regarding proper means of disposing your wastewater.


Q. Are mobile wastewater processing systems expensive?

A. Cost for water processing equipment varies – ranging from $2,500 to $15,000. For instance, the equipment to process wash water for permitted sewer disposal, generated from cleaning restaurant equipment and/ or fleets of vehicles, is approximately $2,500. If a company wishes also to steam clean surfaces such as parking lots, gasoline stations and engines, the water processing equipment is more expensive and complex. It must be capable of removing oil, grease , as well as the trace metals from their waste stream to meet on site sewer discharge requirements. It costs us about $25.00-$50.00 per day per machine operating.


Q. Is the cost for services more if we use an environmental pressure washer?

A. Pricing Survey for our industry indicates that conventional pressure washers who do not contain, collect and process their waste water – charge 5 – 25 cents a square foot. AZPW Maintenance Services Co., Inc., charges 6-15 cents a square foot.


Q. How do you know if your service provider is in compliance ? How do we protect ourselves?

A. Consult with your locally owned public waste water treatment authorities to determine their rules for proper handling and disposal of the wastewater that will be generated from the type of cleaning activities you wish to perform. In Texas, within most jurisdictions, it is required that all pressure washers obtain a written sewer discharge permit from each and every jurisdiction that they provide their services. The sewer discharge requirements vary from jurisdiction to jurisdiction through out the State.


Q. What about dry clean-up methods?

A. Cleaning with dry chemicals usually cost two to three times more than pressure washing. Dry Cleanup products are normally used for cleaning up automotive fluid spills as a quick cleanup method, in between pressure washing. These absorbents should never be left on the surface being cleaned. Be sure to sweep up the agent and dispose of it properly. Don’t put the residual in your garbage dumpster. Our landfills are not set up to deal with hazardous waste. The contaminants can leak back out of the absorbents at the landfill and pollute our groundwater sources.

Beware: There are some products available that require the cleaning agent to be left on the surface being cleaned. It is reapplied each time there is a spill, layer upon layer. Over time, the automotive fluid stains fade. The MSDS clearly states not to mix the cleaner with water. So, it should not be used when it is raining. It is also illegal for a pressure washer to wash this cleaning agent into our storm drains or sewers. The pH (12) of the product is way too high. It does not re mediate metals (lead, cadmium, chromium, copper, mercury, zinc) which found in automotive fluids. The concentration of the absorbent builds up on the surface being cleaned. When it rains, the product washes into the storm drain along with the metals found in automotive fluids, which are all toxic to humans and wildlife.


Q. What is Nonpoint Source Pollution (NPS)?

A. Sources of water pollution can be categorized in two ways. One is contamination which originates from an identifiable point, for example, the end of a pipe or channel. The other is non point sources which affect water quality in a more indirect and diffuse way, such as agricultural or urban runoff.

With point sources of pollution firmly entrenched in the regulatory scheme, the Environmental Protection Agency (EPA) is stepping up its activity to address non point sources: a challenge with significant water quality implications. It is estimated that as a result of gains made in controlling point sources, non point sources now compose over half of the waste load borne by the nation’s waters. The EPA recently released a draft strategy for strengthening non point source management and intends to dramatically pick up the pace in non point source control. The initial focus is on runoff. Storm water is posing an increasing problem as runoff transports pollutants, such as sediment, fertilizers, pesticides, hydrocarbons and other organic compounds and metals, such as lead, into water bodies. In addition, gravity collection systems often overflow and back flow during storms. As a result, flow is only partially treated at the wastewater plant or is bypassed to the nearest stream or river. Increased volumes of runoff also negatively affect groundwater elevations and lessen the volume of water percolating through the soil thereby lessening the dilution of contaminants entering groundwater. Overflows carry untreated pollutants into water courses and back flows can affect the homes of collection system customers.

According to a recent EPA report which is used to establish infrastructure priorities, the U.S. needs nearly $140 billion over the next 20 years to meet wastewater treatment requirements. This includes nearly $45 billion for controlling combined sewer overflows, $44 billion for wastewater treatment in general and $22 billion for new sewer construction. In addition, the EPA estimates $10 billion for upgrading existing wastewater collection systems, $9 billion for non point source control and $7 billion for controlling municipal storm water.
