Es ilegal permitir que cualquier otra cosa que no sea agua de lluvia se descargue en un desagüe pluvial.

Power washing creates wash water (wastewater). Washing vehicles, equipment, and infrastructure (such as sidewalks or buildings) in areas where wastewater flows onto surfaces where it cannot soak in, such as in concrete areas, has the potential to be carried into our local creeks and can be harmful to water quality and creek habitats. Residual wastewater can contain high concentrations of oil and grease, detergents, and other pollutants.

Descargar cualquier cosa, incluida agua potable, directamente al sistema de drenaje pluvial es una violación de las ordenanzas federales, estatales y locales. Las personas o empresas que lavan a presión y no impiden que las aguas residuales entren en los sistemas de drenaje pluviales están sujetas a sanciones civiles o penales.


  • Regulations vary, contact the local municipal storm water program or department to determine restrictions and any potential permit requirements.
  • Prior to each use, determine where any runoff will flow.
  • Protect storm drain inlet(s) to prevent discharge from entering storm drain.
  • Minimize water use.
  • Prior to performing any power washing:
    • Sweep, collect, and dispose of debris.
    • Clean all oil spots using dry methods only, prior to power washing.
    • Dispose of all absorbent material, if used, in the trash.
    • Place oil-absorbent boom around storm drain inlet during power washing if oil spots are present.
  • Beware of pressure washing hazardous materials (lead-based paint, oils, solvents, antifreeze, etc). Washing surfaces that have these materials present may require proper hazmat disposal.


  • Chemicals, detergents, soaps, steam, or heated water shall be contained.
  • Utilize a portable wash pit, vacuum recovery unit, or comparable device to collect water for proper disposal.
    • Drain rinsate to a sump or grit trap prior to discharge into sanitary sewer.
  • Manufactured wastewater collection systems may be commercially available for power washing.


  • If permissible, power wash onto a vegetated or gravel surface where wash water can infiltrate into the ground without runoff.
    • Do not wash equipment or vehicles outdoors on saturated ground or on days when rain is probable.
  • Use a portable containment system to catch wastewater. Containment devices for power washing smaller equipment have included portable vinyl swimming pools, plastic 55-gallon drums on casters, and temporary visqueen lined and bermed work areas.


  • Vacuum, sweep, or shovel any sediment and debris caught by bio-bags or other BMP devices and dispose of properly. These materials can generally be disposed of as regular trash, unless it is known that hazardous materials are present (such as lead paint chips, oils, solvents, antifreeze, etc).
  • Saturated oil booms and socks require disposal at an appropriate hazmat recovery site. Call your local County administered Household Hazardous Waste program or collection facility for more information and locations.
  • All BMPs must be removed upon completion.


  • You MUST obtain permission from the governing authority to discharge to the sanitary sewer.
  • Discharges to the sewer should not contain grease, grit, or any material that could clog piping.
  • Discharge to the sanitary sewer may also be required to be within a specific pH range.
  • With permission, the on-site sanitary sewer can be accessed through a building drain, building sewer, industrial sink, private sewer clean-out, private sampling manhole, or any other privately-owned sanitary sewer access point. (City maintained manholes may only be opened by City staff).


If sanitary sewer and landscaping options are not feasible, check with your local municipality if a written variance for approval to discharge to the storm drain is required.


  1. Lea las etiquetas de los productos de limpieza antes de desechar las aguas residuales. Siga cuidadosamente las instrucciones de uso y eliminación.
  2. Comuníquese con el programa local de Residuos Peligrosos del Hogar administrado por el Condado o con el centro de recolección para obtener más información y ubicaciones.

Power Washing activities shall comply with local storm water ordinances. It is the responsibility of the mobile power washing operator to know and follow all local and regional codes, including obtaining proper permits, for all work to be completed.


  • Tenga un plan escrito.
  • Capacite a los empleados anualmente sobre las regulaciones de aguas pluviales, respuesta a derrames, seguridad personal y manejo y eliminación de desechos peligrosos.
  • Tenga materiales de limpieza de derrames en el lugar.
  • Tenga hojas de datos de seguridad para todos los productos utilizados.

Para una emergencia o un derrame que involucre materiales peligrosos o desechos peligrosos, llame al 911 o al Departamento de Bomberos local.

  • For All Non-Emergency / Non-Hazardous Spills To report a Non-Hazardous spill, or for other useful phone numbers, see Spill Numbers informational reference sheet for your local agency contact information or visit:

¿En qué se diferencian los sistemas de drenaje pluvial y alcantarillado sanitario?

El sistema de drenaje pluvial transporta el agua de lluvia a los arroyos, ríos y el océano locales. Este sistema fue creado para prevenir inundaciones dentro de comunidades y hogares.

Toda el agua y los materiales que ingresan al sistema de drenaje pluvial no se tratan.

El alcantarillado sanitario es un sistema de tuberías que transporta el agua usada desde los edificios hasta una instalación de recolección y tratamiento de aguas residuales, donde se trata el agua y las aguas residuales.

Si ve un desagüe al aire libre y no está seguro de su uso, asuma que es un desagüe pluvial y no descargue agua de lavado en él.

Los arroyos limpios son importantes. Proporcionan un hábitat vital para los peces, recreación y se suman a la belleza de nuestra ciudad.
