Water containing wastes – aka wastewater – from residential,
commercial and industrial processes requires treatment to remove
pollutants prior to discharge. After treatment, the water is
suitable for nonconsumption (nonpotable) and even potable use.
In California, water recycling is a critical component of the
state’s efforts to use water supplies more efficiently. The state
presently recycling about 669,000 acre-feet of water per year and
has the potential to reuse an additional two million acre-feet
Non-potable uses include:
landscape and crop irrigation
stream and wetlands enhancement
recreational lakes, fountains and decorative ponds
toilet flushing and gray water applications
as a barrier to protect groundwater supplies
from seawater intrusion
wetland habitat creation, restoration, and maintenance
Some facilities may have to test for the presence of per- and
polyfluoroalkyl substances (PFAS) in their wastewater, under a
new strategy from the US Environmental Protection Agency. The

environmentally persistent and toxic PFAS in drinking water
drawn downstream of such facilities as well as in fish and
Though many may not know it, throughout its existence the San
Onofre Nuclear Generation Station has discharged wastewater
that contains very low levels of radiation. All nuclear plants
release some effluents, though the nature and amounts can vary
by plant site and configuration. In the case of San Onofre, the
“liquid batch releases” go right into the Pacific. Southern
California Edison, the plant’s operator, insists the levels are
safe for marine life and the humans who swim and surf at San
Onofre State Beach.
UC San Diego says it detected traces of the novel coronavirus
in five areas of campus over the weekend after it greatly

drawn from dozens of buildings.
Property owners in the Sonoma Valley generally receive property
tax bills in early October, which includes a lengthy list of
percentages levied for various bonds, and direct charges for
district fees such as fire, health care and the Sonoma Valley
County Sanitation District. But for the third time in seven
years, said Sonoma resident Scott Pace, that sanitation
district charge has been inaccurate.

This Wednesday, Nov. 11, the Cloverdale City Council’s lone new
agenda item is a costly one to Cloverdale residents — a
proposed hike in the city’s water and sewage rates. The
increases in both water and wastewater rates … is something
that city officials say is needed to help start capital
improvement projects related to the city’s water and wastewater
There’s some fascinating tension around a proposed wastewater
reclamation collaboration in Southern California. The project,
if it goes forward, would provide some 150 million gallons per
day (~170,000 acre feet per year) of treated effluent. Water
now being discharged into the ocean would instead be available
for aquifer recharge within Southern California.
Napa County has achieved a degree of peace – at least for now –

wastewater treatment capacity to support public health and the
environment in this growing community.
The term “crisis on the border” typically refers to immigration
issues or drugs being smuggled into the country. But it has one
more meaning, as we discovered, when we went to the border in
early February: tens of millions of gallons of raw sewage that
spill every year into the Tijuana River on the Mexican side and
flow across the border right into Southern California,
polluting the land, air, and sea.
The U.S. Environmental Protection Agency on Thursday, May 28,
gave a $196.4 million loan to the Inland Empire Utilities
Agency to expand its wastewater treatment plant in Chino. …

neighboring cities served by the plant add residential and
It’s been more than a decade since discussions began about what
would happen to wastewater if the Lytton Tribe were to have
their lands west of town put into federal trust. At its May 20
meeting, the Windsor Town Council voted unanimously to move
forward to the next step, creating an agreement to have the
wastewater treated in the town’s facility.
In hundreds of cities across the USA, scientists hope
monitoring systems will provide an early warning if coronavirus
infections reemerge as communities in some states cautiously
reopen. These monitors don’t rely on testing patients or
tracing contacts. All that’s required? Human waste.
The nation’s environmental watchdog may investigate federal
enforcement of water policy in California after Democratic

virus and surrogates as well as their potential associations
with residuals, sludge, and biosolids.
The U.S. Environmental Protection Agency has proposed spending
$300 million to address the problem of toxic sewage flowing
across the border into San Diego County, legislators announced
Tuesday. The money would be part of the United
States-Mexico-Canada Agreement Implementation Act, and will be
used for the engineering, planning, design and construction of
wastewater infrastructure at the border, officials said.
As a result of compliance with conservation measures through
lower indoor water use, the amount of wastewater effluent was
reduced. This reduction means less water for recycling and
reuse — a source of water often thought of as drought-proof —
and less water for stream augmentation, with a consequence of
potentially impacting streamflow and downstream water
Scientists across the nation are examining Southern
California’s poop — maybe even yours — with the hope of more
quickly identifying COVID-19 hotspots and better preparing for
future surges. The information could also signal when
stay-at-home orders can be safely eased in specific
The latest testing of raw sewage at Lake County Special
Districts’ four treatment facilities found no presence of the
virus that causes COVID-19 at any of the plants late in April,
despite the fact that samples earlier in the month confirmed
The industry and its advocates … are backing a two-phase plan
to extend a lifeline to water utilities and customers who
cannot pay their bills during an economic crisis, and to invest
for the future. Step one in the plan is the provision of
emergency assistance to both groups. There is still a debate
about the size of an aid package for utilities and the most
efficient and effective way of helping customers. But $1.5
billion in customer assistance is a common starting point in
While wastewater surveillance has been used for years in
developing countries to detect outbreaks of polio, in the U.S.,
it has been used more recently to track opioid use within
communities. A spokesperson for the CDC confirmed that the
agency is eyeing wastewater as part of its response to the
pandemic, though it is not yet doing so.
Researchers say the virus can be detected in untreated
wastewater within days of infection and as much as two weeks
before a person grows ill enough to seek medical care — that
is, if symptoms ever materialize at all.
The Water Environment Federation has published the first of a

each day in the river.
From Stanford to the University of Arizona, from Australia to
Paris, teams of researchers have been ramping up wastewater
analyses to track the spread of SARS-CoV-2, the virus that
causes COVID-19. Initial studies show that sewage monitoring,
or “wastewater-based-epidemiology,” could not only tell us how
much the virus might actually be spreading in a community — but
also when the virus has finally gone away.
The EPA has been too busy responding to the deadly coronavirus
to work on its long-awaited proposal to manage huge volumes of
pathogen-infested sewage and stormwater during heavy rains, the
agency’s top wastewater official said Wednesday.
While most of the Earth has been singularly obsessed with an
invisible virus from a foreign land, in this California beach
town, it’s a “crisis on top of crisis’. Not only dealing with
the creepy disease we can’t see, but a river of toxic waste
from a foreign land that we can see, but chose to ignore.
A new poll by the Value of Water Campaign released today shows
that 84 percent of American voters want state and federal
leaders to invest in water infrastructure. The near-unanimous
support amid the COVID-19 pandemic reveals that voters value
water and want elected officials to prioritize investing in
infrastructure — specifically, drinking water and wastewater
Ten Bay Area counties, coordinated by the East Bay Municipal
Utility District, are giving samples of sewage water to
researchers at Stanford for testing. The scientists have
received samples once a week for about the past two months, and
results are expected soon.
The Court decision introduces the concept of a “functional
equivalent of a direct discharge” as a guideline for when a
point source discharge must obtain a permit. It cites the case
of an injection well receiving pollutant discharge that then
travels a few feet through groundwater into navigable waters as
a clear case of “functional equivalent” to direct discharge.
Most businesses across the country and certainly in the
Coachella Valley are dealing with the fallout from the
coronavirus crisis on a daily basis. Beverli Marshall, however,
believes her business might not feel the sting of the
coronavirus for months yet — ultimately, about the same amount
of time it’ll take something that shouldn’t be flushed down a
toilet or rinsed down a drain to make it through the waste
water system of Valley Sanitary in Indio.
The Supreme Court ruled on Thursday that the Clean Water Act
applies to some pollutants that reach the sea and other protected
waters indirectly through groundwater. The case, County of Maui
v. Hawaii Wildlife Fund, No. 18-260, concerned a wastewater
treatment plant on Maui, Hawaii, that used injection wells to
dispose of some four million gallons of treated sewage each
For the April 15th collection systems webinar, we asked
attendees if their agency is experiencing INCREASED maintenance
because of wipes? 64% of the 165 agencies represented said yes
they are experiencing O&M problems due to more wipes in the
system. … Another startling finding was 77% of 191 agencies
surveyed said they are struggling to find PPE supplies. The
most common items those agencies are looking for are face
masks, hand sanitizer and gloves.
Utilities are reporting in industry surveys that they are low
primarily on the specialized N95 masks that block viruses and
other tiny particles. If the virus rampages throughout a
utility’s work force the way it has in meat-processing
facilities in Colorado, Iowa, and South Dakota, it could
jeopardize the treatment and delivery of drinking water and the
proper handling of sewage and stormwater.
Two bipartisan draft water infrastructure bills unveiled this

cause cash flow problems within the next two months or more.
That’s one of the takeaways from a survey of more than 500
water utilities conducted at the end of March by the American
Water Works Association
Southern California Edison, the operators of the San Onofre
Nuclear Generating Station, is still investigating what caused
the release of 7,000 gallons of sewage into the ocean last
month but it appears the culprits were a blockage in the
facility’s sewage treatment plant and a worn out pump switch.
Californians reuse treated wastewater as a water supply, to
irrigate crops, and to support freshwater ecosystems. To get

If you’re a Central Valley farmer and haven’t yet been hit up
by someone about reusing crummy water for irrigation — just
wait. Companies are springing up all over with the latest gizmo
they believe will take nasty, salty water, mostly from shallow
aquifers on the valley’s west side or oilfield produced water,
and make clean “new” irrigation water.
On this episode of our podcast, Parts Per Billion, we speak

The effluent is hauled ashore on barges, hit with a dose of
disinfectant, then deposited into a huge East Bay Municipal
Utility District sewer main called the Alameda Interceptor.
From there, the material joins the underground river of
everything else that’s been flushed down local toilets and
flows to the agency’s wastewater treatment plant at the foot of
the Bay Bridge.
In an alert to state regulators, Southern California Edison,
which operates the power station, said an unexpected surge of
wastewater led to an “upset” at the treatment plant that

could turn off the pumps.
States around the country say they won’t penalize water and
wastewater utilities for failing to meet Clean Water Act permit
requirements due to delays caused by the deadly coronavirus if
those delays are justified and documented. Delays, for example,
could be caused by utility staff who test and monitor water
quality—or lab workers who analyze it—being quarantined with
A sudden influx of water at the sewage treatment facility at
the San Onofre Nuclear Generating Station early Wednesday
morning led to about 7,000 gallons of partially treated
