1. What is recycled water?
The California Water Code defines
recycled water as “water which, as a result of treatment of waste, is suitable
for a direct beneficial use or a controlled use that would not otherwise occur.”
Water recycling allows water managers to match water quality to specific reuse
applications. This reduces the amount of potable water required for non-drinking
uses, ensuring that the best and purest sources of water will be reserved for
the highest use — public drinking water.
2. Who
develops the health standards for recycled water?
The California Department of Health
Services (DHS) establishes and enforces the standards for recycled water. DHS
has established water quality standards and treatment reliability criteria for
recycled water. The North Coast County Water District and customers using the
water for irrigation must meet these requirements for recycled water. The
California Regional Water Quality Control Board issues water recycling permits
based on the established DHS standards.
3. Isn’t it a bit risky to experiment with this kind of water in outdoor
landscape spaces?
No. Recycling water is long past
the experimental stage in this country and throughout the world. It is being
used for crop irrigation as well as to water parks, school grounds and other
open spaces from Florida to California. San Jose, Sunnyvale, Santa Clara, Santa
Rosa, Daly City and other Bay Area communities use it on their parks, schools,
median strips, large landscape areas, and golf courses. Recycled water is used
also in office parks, for indoor fire protection and toilet flushing in
commercial buildings, in fountains and car washes. The Water District staff is
licensed through the DHS and is required to receive continuous educational
training. We are certified in all aspects of water analysis and water treatment
in order to insure that our customers receive safe water.
4. Could recycled water get mixed with the Water District's drinking water
supply?
Absolutely not. Pursuant to state
law, the Water District will construct a separate recycled water delivery
system. There will be no direct inter- or cross connections between the two
water systems. Water systems are inspected annually.
5. How will I know if the water I see sprinkling parks and other outdoor spaces
is drinking water or recycled water?
Landscaped areas irrigated with
recycled water are marked clearly with bilingual signs stating the usage of
recycled water.

6. Does
recycled water give our landscape sufficient minerals?
Yes. Recycled water can play a
major role in the successful management of turf grasses in our area. Because
recycled water is produced from municipal wastewater, the large volumes of water
needed to maintain adequate turf growth are readily available even during
periods of water shortage. The higher nutrient content of nitrogen, phosphorous
and potassium in recycled water is beneficial to turf grasses. In many cases,
turf and other landscape plants will be able to obtain from recycled water all
the phosphorous and potassium they require, and a large part of their nitrogen
requirement. Sufficient micronutrients are also supplied by recycled water.
7.
Who is going to pay for the recycled water retrofit connections?
For existing customers, such as
landscape irrigation accounts, the Water District’s proposed project will pay
100% of most of the connection costs. Complex original systems may present
issues that would be looked at on a case-by-case basis. For future new
customers, a connection fee will apply and plans for dual piping for landscape
irrigation will be required. The Water District and the San Francisco Public
Utilities Commission will share the overall cost of implementing the program.
8. Does recycled water smell bad?
It is possible some people may
detect a slight chlorine odor; however, the odor is usually less than a swimming
pool or hot tub.

9. What
chemicals are used to treat recycled water?
The same ones that are used to
treat drinking water.
10. Will the recycled water be safe for children playing in park areas?
Yes. The California
Department of Health Services has determined that tertiary treated water
complying with California Title 22 standards is safe. Park areas have been
irrigated safely with recycled water with no reported cases of people getting
ill.
11. Children play in the parks and sometimes drink from sprinklers. What happens
if a child drinks from a sprinkler?
Just as children may
swallow some water at a beach, they could swallow some recycled water without
getting sick. Adverse health effects from recycled water could appear only if it
were ingested in large quantities over an extended period of time; consequently,
recycled water is not intended for drinking. There are no reported cases of
people getting sick from recycled water.
12. Has anybody
ever gotten sick from recycled water?
No. Recycled water is
commonly used throughout the country, and there are no reported cases of illness
or allergies as a result.

13. What happens if a child falls down in a pool of recycled water and has
an open cut? Will the cut get infected?
No. The cut should be
cleaned just as would be the case after any fall. Getting dirt into the cut
would be more serious than the exposure to recycled water. The treatment process
utilized will allow for the presence of a disinfectant to exist in the recycled
water in order to protect against infection.
14. What happens if a dog or cat drinks from a recycled water puddle?
Just the same thing
that happens when they drink water running down a gutter in the street: no
harmful effects. The water will be safer than if the pet drinks from a ditch or
pond.
15. Does recycled
water cause spots on vehicles?
No. The spots you are
referring to are normally the effects of hard water on smooth surfaces. Any type
of water will spot cars if allowed to dry on the surface, and water that has
more minerals could produce more noticeable spotting. However, irrigation
schedules will occur at night and if cars are in driveways, it is unlikely they
will be impacted with overspray from sprinklers.

16. Does the Water District plan to test recycled water in the community
prior to construction of the project?
Yes.
The Water District, in partnership with the San Francisco Public Utilities
Commission, will conduct a pilot test using recycled water to irrigate a
practice putting green at Sharp Park Golf Course. The objective of the pilot
test is to assess turf sensitivity to recycled water and to develop user &
public familiarity with recycled water in the community.
The
pilot test has been rescheduled to begin in early July and continue through
August 2004.

websites where I can find more information? YES.
