Hot water Pressure washing with waste water capture and reclamation

Reclamation pressure washing is the process of capturing, containing, and safely disposing of the waste and waste water generated during pressure washing operations.  The reasons for doing this range between environmental considerations and laws, to preventing property damage, to preventing making a larger mess than the original one you were hired to clean up.

We accomplished this task by integrating and marrying standard commercial hot water pressure washer skids to very powerful gas powered vacuum blowers, transfer pumps, sediment separation tanks, bulk water tanks, waste water storage tanks, various live hose reels and adequate valving to ensure that we can do this work without clogging up our equipment with the considerable waste that we remove from the large jobs we undertake.  Our captured waste water is then transported to a suitable waste water treatment facility.

Other very useful applications include the ability to pressure wash indoors with no mess and no flooding using specialized and adapted vacuum attachments.

Environmentally we are able to do quite a bit with these machines when we take on trash compactors that sit next to storm drains that drain out to local creeks.

The tremendous amount of hydrocarbons and heavy metals dislodged from steam cleaning heavy construction equipment are also voided as we capture all the waste water from our work.

These reclamation machines are next evolution of pressure washing as we move into a greener and more ecologically aware future.  Indeed many states and large companies already require their pressure washing vendors to capture and contain their waste water...

  1. Hiring a contractor who has the ability to reclaim used wash water is the best way to avoid costly fines from governmental authorities tasked with enforcing the Clean Water Act.

  2. Waste water reclamation allows the use of hot water which is a far superior method in most cleaning situations.

  3. Unless the project you want your contractor to perform is giant, the cost of reclamation pressure washing is less than the vacuum truck fees incurred when a local inspector requires that a storm drain basin be cleaned out.

  4. Although more expensive to employ, reclamation pressure washing ensures that the used wash water which is usually unpleasant to smell or even to look at, is not discharged to a place where the wildlife present are biologically unequipped to deal with it and remain healthy.

  5. In a developed where the used wash water will run to a storm drain, regardless of the dirt or contaminants you want your contractor to clean up, waste water capture is the only option if you don’t want your waste discharged directly to the nearest stream, river, lake, or the Puget Sound.


  1. Hot water pressure washing uses significantly less water when compared with cold water pressure washing to the same standard of cleanliness. In general it’s about twice as water efficient, however when oil, traffic, and other petroleum based stains or chewing gum are considered, this advantage is compounded many times over. Hot water simply cuts through oil based stains much more efficiently.

  2. Hot water pressure washing dislodges far more surface dirt with less energy and substantially less water when compared with cold water.

  3. Simply heating the water in a pressure washing system is in many ways equal to or better than introducing detergent additives to cold water. A great many detergents available today are not something you want on your unprotected skin, so it’s not a good idea to flush these chemicals out into the natural environment, through municipal storm drains which lead to the “Waters of the State”. These natural waters and water ways are protected by the Clean Water Act, passed into law in the 1940’s and significantly expanded in the 1970’s.

  4. Although not yet heavily enforced, the use of hot water is generally not permitted and not legal, unless a reclamation system is also employed, precisely because it is so much more effective at dislodging and releasing contaminants. To take it a bit further, pressure washing in general, including cold water only, requires the use of a reclamation system. Nothing but natural rain is legally permitted to enter any municipal storm drain.

  5. Without including the added cost of a reclamation system which is usually required when pressure washing, the net benefits of using hot water far outweigh the added cost of fuel used at the burner where the water is heated.

  6. While providing a superior cleaning result, hot water will lessen the amount of time your contractor and his equipment are exposed to your customers or residents.

  7. The use of hot water significantly reduces the cost of waste water transport and disposal because it is generally twice as water efficient.

  8. Since labor, fuel, and water consumption rise so drastically in most cleaning situations when using cold water, generally it is more efficient to just settle for a lesser result.

  9. The most common myth and most common false assumption about hot water pressure washing is that it costs more for the contractor to perform, and thus will cost more for the customer. An experienced pressure washing contractor knows that using hot water actually costs him less resources, in addition to providing better looking results. The equipment is more expensive to acquire initially but ultimately is costs less.
