Amended by AB 1406:

Water Code §13553

Recycled water, instead of potable water, may now be used indoors in condominium projects created on or after January 1, 2008, subject to all of the following conditions.

Before recycled water can be used indoors in any condo project, the agency delivering the recycled water to the condo project must file a report with the appropriate regional water quality control board and receive written approval of the report from the State Department of Public Health. The report must include, but is not limited to, all of the following:

  • that the potable water service to each condo project will have a backflow protection device approved by the State Department of Public Health to protect the agency’s public water system, and that the device will be annually inspected and tested by a person certified in the inspection of these devices;
  • that any plumbing modifications in a condo unit or any physical alteration of the project will be done in compliance with state and local plumbing codes;
  • that each condo project will be tested by the recycled water agency or the responsible local agency at least once every four years to ensure the condo projects potable and nonpotable water systems do not cross; and
  • that the recycled water lines will be color-coded consistent with current law.

The recycled water agency or the responsible local agency must maintain records of all texts and annual inspections.

The condo’s declaration, which are part of the governing documents, must:

· state that the laws and regulations governing recycled water apply;

· state that no exceptions to those laws and regulations will be permitted;

· include the report to the appropriate regional water quality control board noted above; and

· include the following statement:


This property is approved by the State Department of Public health for the use of recycled water for toilet and urinal flushing. This water is not potable, is not suitable for indoor purposes other than toilet and urinal flushing purposes, and requires dual plumbing. Alterations and modifications to the plumbing system require a permit and are prohibited without first consulting with the appropriate local building code enforcement agency and your property management company or homeowners’ association to ensure that the recycled water is not mixed with the drinking water.”

This is effective January 1, 2008.
