Tips for Residential
Pool, Landscape and
Hardscape Drains
Pool Maintenance
All pool water discharged to the curb, gutter or
permitted pool drain from your property must meet the
following water quality criteria:
The residual chlorine does not exceed
0.1 mg/L (parts per
million).
The pH is between
6.5 and 8.5.
The water is free
of any unusual
coloration.
There is no discharge
of filter media or acid
cleaning wastes.
Some cities have ordinances that do not allow pool
water to be discharged to the storm drain. Check with
your city.
Landscape and
Hardscape Drains
The following recommendations will help reduce or
prevent pollutants from your landscape and hardscape
drains from entering the street, gutter or storm drain.
Unlike water that enters the sewer (from sinks and
toilets), water that enters a landscape or hardscape
drain is not treated before entering our creeks, rivers,
bays and ocean.
Household Activities
Do not rinse spills of materials or chemicals to any
drain.
Use dry cleanup methods such as applying cat
litter or another absorbent material, then sweep it
up and dispose of it in the trash. If the material is
hazardous, dispose of it at a Household Hazardous
Waste Collection Center (HHWCC). For locations,
call (714) 834-6752 or visit www.oclandfills.com.
Do not hose down your driveways, sidewalks or
patios to your landscape or hardscape drain.
Sweep up debris and dispose of it in the trash.
Always pick up after your pet. Flush waste down
the toilet or dispose of it in the trash.
Tips for Residential Pool, Landscape and Hardscape Drains
Do not store items such as cleaners, batteries,
automotive fluids, paint products, TVs, or
computer monitors uncovered outdoors. Take
them to a HHWCC for disposal.
Yard Maintenance
Do not overwater. Water by hand or set
automated irrigation systems to reflect seasonal
water needs.
Follow directions on
pesticides and fertilizers
(measure, do not estimate
amounts) and do not use
if rain is predicted within
48 hours.
Cultivate your garden
often to control weeds
and reduce the need to
use chemicals.
Vehicle Maintenance
Never pour oil or antifreeze down your
landscape or hardscape drain. Recycle these
substances at a service station, a waste collection
center or used oil recycling center. For
locations, contact the Used Oil Program at 1-800-
CLEANUP or visit www.CLEANUP.org.
Whenever possible, take your vehicle to a
commercial car wash.
If you do wash your vehicle at home, do not
allow the washwater to go down your landscape
or hardscape drain. Instead, dispose of it in
the sanitary sewer (a sink or toilet) or onto an
absorbent surface such as your lawn.
Use a spray nozzle that will shut off the water
when not in use.
Do your part to prevent water
pollution in our creeks, rivers, bays
and ocean.
Clean beaches and healthy creeks, rivers,
bays, and ocean are important to Orange
County. However, many common household
activities can lead to
water pollution if you’re
not careful.
Litter, oil, chemicals and
other substances that
are left on your yard or
driveway can be blown
or washed into storm
drains that flow to the
ocean. Over-watering
your lawn and washing
your car can also flush
materials into the storm
drains. Unlike water in sanitary sewers
(from sinks and toilets), water in storm
drains is not treated.
You would never pour soap, fertilizers or oil
into the ocean, so don’t let them enter
streets, gutters or storm drains. Follow the
easy tips in this brochure to help prevent
water pollution.GENUINERECYCLEDPAPER

Help Prevent Ocean Pollution:
Household Tips
Gardening Activities
�Follow directions on pesticides and
fertilizers, (measure, do not estimate
amounts) and do not use if rain is
predicted within 48 hours.
�Water your lawn and garden by hand to
control the amount of water you use. Set
irrigation systems to reflect seasonal
water needs. If water flows off your yard
and onto your driveway or sidewalk,
your system is over-watering.
�Mulch clippings or leave them on the
lawn. If necessary, dispose in a green
waste container.
�Cultivate your garden often to control
weeds.
Washing and Maintaining Your Car
�Take your car to a commercial car wash
whenever possible.
�Choose soaps, cleaners, or detergents
labeled “non-toxic,” “phosphate free” or
“biodegradable.” Vegetable and citrus-
based products are typically safest for
the environment, but even these should
not be allowed into the storm drain.
�Shake floor mats into a trash can or
vacuum to clean.
�Do not use acid-based wheel cleaners and
“hose off” engine degreasers at home.
They can be used at a commercial facility,
which can properly process the washwater.
�Do not dump washwater onto your
driveway, sidewalk, street, gutter or
storm drain.Excess washwater shouldbe disposed of in the sanitary sewers
(through a sink, or toilet) or onto an
absorbent surface like your lawn.
�Use a nozzle to turn off water when not
actively washing down automobile.
�Monitor vehicles for leaks and place
pans under leaks. Keep your car well
maintained to stop and prevent leaks.
�Use cat litter or other absorbents and
sweep to remove any materials deposited
by vehicles. Contain sweepings anddispose of at a HHWCC.
�Perform automobile repair and
maintenance under a covered area and
use drip pans or plastic sheeting to keep
spills and waste material from reaching
storm drains.
�Never pour oil or antifreeze in thestreet, gutter or storm drains.
Recycle these substances at a service
station, HHWCC, or used oil recycling
center. For the nearest Used Oil
Collection Center call 1-800-CLEANUP
or visit www.ciwmb.ca.gov/UsedOil.

Do your part to prevent
water pollution in our
creeks, rivers, bays and ocean.
Clean beaches and healthy
creeks, rivers, bays and ocean
are important to Orange County.
However, not properly disposing
of household hazardous waste can
lead to water pollution. Batteries,
electronics, paint, oil, gardening
chemicals, cleaners and other
hazardous materials cannot be
thrown in the trash. They also must
never be poured or thrown into
yards, sidewalks, driveways, gutters
or streets. Rain or other water could
wash the materials into the storm

Pollution Prevention
Leftover household products that contain
corrosive, toxic, ignitable, or reactive
ingredients are
considered to
be “household
hazardous waste”
or “HHW.” HHW
can be found
throughout your
home, including the
bathroom, kitchen,
laundry room and
garage.
Disposal of HHW down the drain, on the
ground, into storm drains, or in the trash
is illegal and unsafe.
Proper disposal of HHW is actually easy.
Simply drop them off at a Household
Hazardous Waste Collection Center
(HHWCC) for free disposal and recycling.
Many materials including anti-freeze, latex-
based paint, motor oil and batteries can
be recycled. Some centers have a “Stop &
Swap” program that lets you take partially
used home, garden, and automobile
products free of charge. There are four
HHWCCs in Orange County:
Anaheim: ..................1071 N. Blue Gum St
Huntington Beach: .........17121 Nichols St
Irvine:............................ 6411 Oak Canyon
San Juan Capistrano:... 32250 La Pata Ave
Centers are open Tuesday-Saturday, 9 a.m.-

or under a cover.
When possible, use non-hazardous
products.
Reuse products whenever possible or
share with family and friends.
Purchase only as much of a product as
you’ll need. Empty containers may be
disposed of in the trash.
HHW can be harmful to humans,
pets and the environment. Report
emergencies to 911.

Clean beaches and healthy
creeks, rivers, bays and
ocean are important
to Orange County. However,
many common activities such as
pest control can lead to water
pollution if you’re not careful.
Pesticide treatments must be
planned and applied properly
to ensure that pesticides do
not enter the street, gutter or
storm drain. Unlike water in
sanitary sewers (from sinks and
toilets), water in storm drains is
not treated before entering our
waterways.
You would never dump pesticides
into the ocean, so don’t let it
enter the storm drains. Pesticides
can cause significant damage
to our environment if used
improperly. If you are thinking
of using a pesticide to control a
pest, there are some important
things to consider.

The Ocean Beginsat Your Front Door
Responsible
Pest Control
Printed on Recycled Paper
Key Steps to Follow:
Step 1: Correctly identify the pest (insect,
weed, rodent, or disease) and verify that it is
actually causing the problem.
This is important
because beneficial
insects are often
mistaken for pests
and sprayed with pesticides needlessly.
Consult with a
Certified Nursery
Professional at a local nursery or garden center or send a sample of the pest to the Orange
County Agricultural Commissioner’s Office.
Determine if the pest is still present – even
though you see damage, the pest may have left.
Step 2: Determine
how many pests are
present and causing
damage.
Small pest populations
may be controlled
more safely using non-
pesticide techniques. These include removing food sources, washing off leaves with a strong
stream of water, blocking entry into the home
using caulking and replacing problem plants
with ones less susceptible to pests.
Step 3: If a pesticide must be used, choose the least toxic chemical.
Obtain information on the least toxic pesticides
that are effective at controlling the target
pest from the UC Statewide Integrated Pest Management (IPM) Program’s Web site at
www.ipm.ucdavis.edu.
Seek out the assistance of a Certified Nursery
Professional at a local nursery or garden center when selecting a pesticide. Purchase the
smallest amount of pesticide available.
Apply the pesticide to the pest during its most
vulnerable life stage. This information can be found on the pesticide label.
Step 4: Wear appropriate protective clothing.
Follow pesticide labels regarding specific types of protective equipment you should wear.
Protective clothing should always be washed
separately from other clothing.
Step 5: Continuously monitor external conditions when applying pesticides such as
weather, irrigation, and the presence of children
and animals.
Never apply pesticides when rain is predicted within the next 48 hours. Also, do not water
after applying pesticides unless the directions say
it is necessary.
Apply pesticides when the air is still; breezy conditions may cause the spray or dust to drift
away from your targeted area.
In case of an emergency call 911 and/or the
regional poison control number at (714) 634-5988 or (800) 544-4404 (CA only).
For general questions you may also visit www.calpoison.org.
Step 6: In the event of accidental spills,
sweep up or use an absorbent agent to remove
any excess pesticides. Avoid the use of water.
Be prepared. Have a broom, dust pan, or dry
absorbent material, such as cat litter, newspapers
or paper towels, ready to assist in cleaning up
spills.
Contain and clean up the spill right away. Place
contaminated materials in a doubled plastic bag.
All materials used to clean up the spill should
be properly disposed of according to your local Household Hazardous Waste Disposal site.
Step 7: Properly store and dispose of unused
pesticides.
Purchase Ready-To-
Use (RTU) products
to avoid storing
large concentrated
quantities of pesticides.
Store unused chemicals in a locked cabinet.
Unused pesticide chemicals may be disposed of at a Household Hazardous Waste Collection
Center.
Empty pesticide containers should be triple
rinsed prior to disposing of them in the trash.

Tips for Pool Maintenance
When permanently removing large quantities of
soil, a disposal location must be found prior to
excavation. Numerous businesses are available to
handle disposal needs. For disposal options, visit
www.ciwmb.ca.gov/SWIS.
Prevent erosion by planting fast-growing annual and
perennial grasses. They will shield and bind the soil.
Recycle
Use a construction and demolition recycling company to recycle lumber, paper, cardboard, metals, masonry (bricks, concrete, etc.), carpet, plastic, pipes (plastic, metal and clay), drywall, rocks, dirt and green waste.
For a listing of construction and demolition recycling locations in your area, visit www.ciwmb.ca.gov/recycle.
Spills
Clean up spills immediately by using an absorbent material such as cat litter, then sweep it up and dispose of it in the trash.
Immediately report spills that have entered the street, gutter or storm drain to the County’s 24-Hour Water Pollution Problem Reporting Hotline at (714) 567-6363 or visit www.ocwatersheds.com to fill out an incident reporting form.
Home improvement projects can cause significant
damage to the environment. Whether you hire
a contractor or work on the house yourself, it
is important to follow these simple tips while
renovating, remodeling or improving your home:
General Construction
Schedule projects for dry
weather.
Keep all construction debris
away from the street, gutter
and storm drain.
Store materials under cover
with temporary roofs or plastic
sheets to eliminate or reduce
the possibility that rainfall,
runoff or wind will carry
materials from the project site
to the street, storm drain or
adjacent properties.
Building Materials
Never hose materials into a street, gutter or storm
drain.
Exposed piles of construction material should not be
stored on the street or sidewalk.
Minimize waste by ordering only the amount of
materials needed to complete the job.
Do not mix more fresh concrete than is needed for
each project.
Wash concrete mixers and equipment in a
designated washout area where the water can flow
into a containment area or onto dirt.
Dispose of small amounts of dry excess materials in
the trash. Powdery waste, such as dry concrete, must
be properly contained within a box or bag prior to
disposal. Call your local trash hauler for weight and
size limits.
Paint
Measure the room or object to be painted, then buy
only the amount needed.
Place the lid on firmly and store the paint can upside-
down in a dry location away from the elements.
Tools such as brushes, buckets and rags should never
be washed where excess water can drain into the
street, gutter or storm drain. All tools should be
rinsed in a sink connected to the sanitary sewer.
When disposing of paint, never put wet paint in the
trash.
Dispose of water-based paint by removing the lid
and letting it dry
in the can. Large
amounts must be
taken to a Household
Hazardous Waste
Collection Center
(HHWCC).
Oil-based paint is a
household hazardous
waste. All leftover
paint should be taken
to a HHWCC.
For HHWCC locations and hours, call (714) 834-6752
or visit www.oclandfills.com.
Erosion Control
Schedule grading and excavation projects for dry weather.
When temporarily removing soil, pile it in a contained, covered area where it cannot spill into the street, or obtain the required temporary encroachment or street closure permit and follow the conditions instructed by the permit.

can lead to water pollution
if you’re not careful.
Fertilizers, pesticides and
other chemicals that are left
on yards or driveways can
be blown or washed into
storm drains that flow to the
ocean. Overwatering lawns
can also send materials into
storm drains. Unlike water
in sanitary sewers (from sinks

Printed on Recycled Paper
Tips for Landscape and GardeningTips for Landscape & Gardening
Never allow gardening products or
polluted water to enter the street, gutter
or storm drain.
General Landscaping Tips
Protect stockpiles and materials from
wind and rain by storing them under
tarps or secured plastic sheeting.
Prevent erosion of slopes by planting
fast-growing, dense ground covering
plants. These will shield and bind the
soil.
Plant native vegetation
to reduce the amount
of water, fertilizers, and
pesticide applied to the
landscape.
Never apply pesticides
or fertilizers when rain is
predicted within the next 48 hours.
Garden & Lawn Maintenance
Do not overwater. Use irrigation
practices such as drip irrigation,
soaker hoses or micro spray systems.
Periodically inspect and fix leaks and
misdirected sprinklers.
Do not rake or blow
leaves, clippings or
pruning waste into
the street, gutter
or storm drain.
Instead, dispose
of green waste by
composting, hauling
it to a permitted
landfill, or recycling it through your
city’s program.
Use slow-release fertilizers to
minimize leaching, and use organic
fertilizers.
Read labels and use only as directed.
Do not over-apply pesticides or
fertilizers. Apply to spots as needed,
rather than blanketing an entire
area.
Store pesticides, fertilizers and other
chemicals in a dry covered area to
prevent exposure that may result
in the deterioration
of containers and
packaging.
Rinse empty
pesticide containers
and re-use rinse water
as you would use the
product. Do not dump rinse water
down storm drains. Dispose of empty
containers in the trash.
When available, use non-toxic
alternatives to traditional pesticides,
and use pesticides specifically
designed to control the pest you are
targeting. For more information, visit
www.ipm.ucdavis.edu.
If fertilizer is spilled, sweep up the
spill before irrigating. If the spill is
liquid, apply an absorbent material
such as cat litter, and then sweep it up
and dispose of it in the trash.
Take unwanted pesticides to a

Why You Should Pick Up After
Your Pet
It’s the law!
Every city has
an ordinance
requiring you
to pick up
after your pet.
Besides being
a nuisance, pet
waste can lead to water pollution, even
if you live inland. During rainfall, pet
waste left outdoors can wash into storm
drains. This waste flows directly into our
waterways and the ocean where it can
harm human health, marine life and
the environment.
As it decomposes, pet waste demands
a high level of oxygen from water.
This decomposition can contribute to
killing marine
life by reducing
the amount of
dissolved oxygen
available to
them.
Have fun with
your pets, but
please be a
responsible pet
owner by taking
care of them and the environment.
Take a bag with you on walks to pick
up after your pet.
Dispose of the waste in the trash or in
a toilet.
