ORDINANCE OF THE CITY OF CHULA VISTA AMENDING
CHAPTER 15.28 OF THE CHULA VISTA MUNICIPAL CODE
BY ADDING SECTION 15.28.020, RESIDENTIAL
GRAYWATER STUB-OUT
WHEREAS, on May 3, 2011 City Council approved Resolution 2011-076 in which City
Council adopted the Climate Adaptaton Strategies and approved their implementation; and
WHEREAS, the adopted Climate Adaptation Strategies will help reduce the City's future
risks and costs from expected local climate change impacts; and
WHEREAS, the Implementation Plan for Strategy #4, Local Water Supply and Reuse,
proposed adopting new regulations to incorporate clothes washer graywater plumbing stub-out in
new residential development; and
WHEREAS, the Department of Water Resources and the Department of Housing and
Community Development adopted graywater regulations in the 20]0 Californian Plumbing Code
Chapter 16A, Part I; and
WHEREAS, clothes washer graywater systems constructed according to Chula Vista
Clothes Washer Graywater Pre-Plumbing and Stub-Out for New Residential Construction and
operated according to the 2010 California Plumbing Code Chapter 16A provide a safe method of
reducing potable water demand; and
WHEREAS, a clothes washer graywater system can save a typical single-family dwelling
up to 7,000 gallons of potable water per yeaz; and
WHEREAS, the installation of a stub-out at time of construction greatly facilitates the
use of graywater in residences; and
WHEREAS, the City Council specifically and expressly finds and declazes that adding
section 15.28.020 to Chapter 15.28 is necessary due to local climatic conditions. As a result of
prolonged droughts exacerbated by climate change, it is anticipated that water supplies from
imported sources aze reduced, and furthermore, as a result of population and economic growth,
demand for water is expected to increase. These impacts could limit imported water availability,
lead to higher demand for local water sources and increase utility costs. Requiring single-source
graywater stub-out in new residential development facilitates the use of graywater for irrigation
which in turn helps address these water-related climate change impacts.
