Section 17921.5 Of Chapter 2. Rules And Regulations From California Health And Safety Code >> Division 13. >> Part 1.5. >> Chapter 2.
17921.5
. (a) For purposes of this section, "recycled water" has the
same meaning as that term is defined in subdivision (n) of Section
13050 of the Water Code, and is consistent with the recycled water
use criteria specified in Chapter 3 (commencing with Section
60301.100) of Division 4 of Title 22 of the California Code of
Regulations.
(b) (1) The department shall conduct research to assist in the
development of mandatory building standards for the installation of
recycled water systems for newly constructed single-family and
multifamily residential buildings. In conducting this research, the
department shall actively consult with the State Water Resources
Control Board, the State Department of Public Health, and other
interested parties, including, but not limited to, public water
systems, recycled water producers, product manufacturers, local
building officials, apartment and other rental property owners,
California-licensed contractors, and the building industry.
(2) In researching, developing, and proposing mandatory building
standards under this section, the department is authorized to expend
funds from the Building Standards Administration Special Revolving
Fund, upon appropriation pursuant to Section 18931.7.
(3) Research conducted to propose building standards pursuant to
this section shall include, but is not limited to, the following:
(A) Potential outdoor applications for recycled water, consistent
with the recycled water use criteria specified in Chapter 3
(commencing with Section 60301.100) of Division 4 of Title 22 of the
California Code of Regulations.
(B) Potential indoor applications for recycled water, consistent
with the recycled water use criteria specified in Chapter 3
(commencing with Section 60301.100) of Division 4 of Title 22 of the
California Code of Regulations. With respect to indoor applications,
the department shall consider whether to adopt or recommend measures
in addition to the current standards adopted in the California
Plumbing Code in Title 24 of the California Code of Regulations to
ensure the safe installation of indoor recycled water piping or
systems, including, but not limited to, requiring purple pipe or
special markings on recycled water piping that states clearly whether
it is approved for indoor use, or recommending restrictions on who
may purchase or install recycled water piping for indoor use.
(C) The cost of various recycled water systems.
(D) The estimated quantity of water savings under varying levels
of application of recycled water in residential buildings and
building site landscaped areas.
(4) The department may research standards for different types of
water recycling systems, including noncentralized systems, but shall
only mandate systems to the extent that they meet all of the health
and safety standards specified in this section.
(c) (1) The department shall submit for adoption mandatory
building standards for the installation of recycled water systems for
newly constructed single-family residential and multifamily
residential buildings. The department shall submit the proposed
mandatory building standards to the California Building Standards
Commission for consideration during the 2016 Intervening Code
Adoption Cycle, and may propose the amendment or repeal of these
mandatory standards as necessary in future code adoption cycles,
consistent with the recycled water use criteria specified in Chapter
3 (commencing with Section 60301.100) of Division 4 of Title 22 of
the California Code of Regulations.
(2) When developing the application provisions for the mandatory
building standards, the department shall limit the mandate to install
recycled water systems within residential buildings and building
site landscaped areas to only those areas within a local jurisdiction
that have feasible and cost-efficient access to a water recycling
facility, or that have been identified by the local jurisdiction
within a planned service area for the provision of recycled water for
which a specific implementation timeline has been identified by the
public water system in its most recent urban water management plan.
(3) The mandate to install recycled water piping shall not apply
to service areas in which the only recycled water use is for potable
purposes, or in which net nonpotable deliveries are anticipated to
remain level or decrease as a result of the potable reuse project.
(4) The department shall develop the application provisions for
the mandatory building standards required under paragraph (1), in
consultation with the State Water Resources Control Board, public
water systems, recycled water producers, and water research
associations.
(5) A city, county, or city and county, in consultation with the
public water system and recycled water producer, may further reduce
the area for which the mandate to install recycled water piping
applies, if the local public water system or recycled water producer
finds that providing recycled water to an area is not feasible or
cost effective.
