2. General Information

   What is Greywater?

   Greywater is untreated water that drains from your clothes washer, bathtub, shower, or bathroom sink. Graywater has low levels of contaminants, but when handled properly, it can be used for non-potable purposes such as landscape irrigation.

   What Types of Greywater Systems Are Eligible for Rebate?

   Only HCD-1 Clothes Washer Systems are eligible.  These systems do not require a permit to complete.  Any other more advanced system will both not be eligible and also require a permit to complete work.

   What is a “HCD-1 Clothes Washer System”?

   HCD-1 Clothes Washer System, more commonly known as “Laundry to Landscape” is a system that uses water from your washing machine to irrigate trees, shrubs, or non-edible plants.

   What are the requirements for the System?

   The system shall adhere to the California Plumbing Code

   1503.1.1 [HCD 1] Clothes Washer System

   A clothes washer system in compliance with all of the following is exempt from the construction permit specified in Section 1.8.4.1 and may be installed or altered without a construction permit:

   1. If required, notification has been provided to the enforcing agency regarding the proposed location and installation of a gray water irrigation or disposal system.
   2. The design shall allow the user to direct the flow to the irrigation or disposal field or the building sewer. The direction control of the gray water shall be clearly labeled and readily accessible to the user.
   3. The installation, change, alteration, or repair of the system does not include a potable water connection or a pump and does not affect other building, plumbing, electrical, or mechanical components including structural features, egress, fire-life safety, sanitation, potable water supply piping, or accessibility.  Note: The pump in a clothes washer shall not be considered part of the gray water system.
   4. The gray water shall be contained on the site where it is generated.
   5. Gray water shall be directed to and contained within an irrigation or disposal field.
   6. Ponding or runoff is prohibited and shall be considered a nuisance.
   7. Gray water may be released above the ground surface provided at least two (2) inches (51 mm) of mulch, rock, or soil, or a solid shield covers the release point. Other methods which provide equivalent separation are also acceptable.
   8. Gray water systems shall be designed to minimize contact with humans and domestic pets.
   9. Water used to wash diapers or similarly soiled or infectious garments shall not be used and shall be diverted to the building sewer.
   10. Gray water shall not contain hazardous chemicals derived from activities such as cleaning car parts, washing greasy or oily rags, or disposing of waste solutions from home photo labs or similar hobbyist or home occupational activities.
   11. Exemption from construction permit requirements of this code shall not be deemed to grant authorization for any gray water system to be installed in a manner that violates other provisions of this code or any other laws or ordinances of the enforcing agency.
   12. An operation and maintenance manual shall be provided to the owner. Directions shall indicate that the manual is to remain with the building throughout the life of the system and upon change of ownership or occupancy.
   13. Gray water discharge from a clothes washer system through a standpipe shall be properly trapped in accordance with Section 1005.0.
