Gray water, also spelled as grey water, is water that already has
been used domestically, commercially and industrially. This
includes the leftover, untreated water generated from clothes
washers, bathtubs and bathroom sinks.
This 25-minute documentary-style DVD, developed in partnership
with the California Department of Water Resources, provides an
excellent overview of climate change and how it is already
affecting California. The DVD also explains what scientists
anticipate in the future related to sea level rise and
precipitation/runoff changes and explores the efforts that are
underway to plan and adapt to climate.
As the state’s population continues to grow and traditional water
supplies grow tighter, there is increased interest in reusing
treated wastewater for a variety of activities, including
irrigation of crops, parks and golf courses, groundwater recharge
and industrial uses.
The 28-page Layperson’s Guide to California
Wastewater is an in-depth, easy-to-understand publication
that provides background information on the history of wastewater
treatment and how wastewater is collected, conveyed, treated and
disposed of today. The guide also offers case studies of
different treatment plants and their treatment processes.

This water source is a common way to recycle water and stretch
urban water supplies. As part of this, gray water ‘harvesting’
(the collecting of gray water from sinks, showers, etc.) is
increasingly popular, especially as a way to flush toilets.
