Section 18940.6 Of Chapter 4. The California Building Standards Code From California Health And Safety Code >> Division 13. >> Part 2.5. >> Chapter 4.
18940.6
. (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 California Building Standards Commission shall conduct
research to assist in the development of mandatory green building
standards for the installation of recycled water systems for newly
constructed commercial and public buildings, in consultation with the
State Water Resources Control Board 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 commission is authorized to expend
funds from the Building Standards Administration Special Revolving
Fund, upon appropriation pursuant to Section 18931.7.
(3) Research conducted in order 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 commission 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 or systems 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 commercial and public buildings
and building site landscaped areas.
(4) The commission 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 commission shall adopt mandatory building standards
for the installation of recycled water systems for newly constructed
commercial and public buildings. The commission shall consider the
proposed mandatory building standards during the 2016 Intervening
Code Adoption Cycle and may amend 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 commission shall limit the mandate to install
recycled water systems within commercial and public 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 commission 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.
