The Bioretention Geek

Ukiah, the city I work in, recently renovated the entire downtown area with new sidewalks, paved road, and all new trees with planter areas. In full transparency, I was involved in aspects of the planning of this project but not the design. When a co-worker of mine made a criticism regarding the new planters at all the street corners, I was excited to actually have some rare insight that I felt was useful in a nerdy sort of way. He complained that the contractor left the planter areas several inches too shallow and made an opening in the curb which will likely flood and dump garbage and dirty water around the new plants just put in. “Exactly the point!” was my response which only made him more confused, and as I presume, makes him not the only one. Let me geek out with you in a science meets nature sort of way.

Most cities and developers are required to reduce storm water pollution to our local waterways as well as promote groundwater recharge. This is all part of the program you may have heard about called Low Impact Development or LID. To accomplish this, many creative designs are integrated into major roadway projects and new developments such as the already mentioned bioretention planters or bioswales.

Bioretention planters are contained areas with walled vertical sides such as a sidewalk curb. These areas are typically a few feet deep with a thick filtration fabric surrounding the walled sides and a natural bottom which keeps water that enters the planter from travelling under adjacent roads or sidewalks but rather goes straight down to recharge the earth. The planter will then be filled with a specialized bioretention soil up to a level just below the gutter height to allow water to enter the area which makes the top of the soil typically 6-8” below the adjacent sidewalk. The design will carefully select a wide variety of plants for these bioretention areas that will stabilize the soil, remove pollutants through physical, biological, and chemical processes, and look aesthetically pleasing especially when surrounded by so much hardscape. These features can even have a positive impact for birds, butterflies, and bees by providing additional habitat and pollinator friendly plants. Stormwater is typically directed to the surface of the bioretention, and pollutants are filtered out as the runoff percolates vertically through the amended soil section. The plants help keep the amended soil section biologically active and help absorb and grab various pollutants before reaching the storm drain system or nearby waterbodies.

During heavy rains, some bioretention planters have a storm drainpipe installed in them with an inlet just above the soil level that will capture excess water that is unable to infiltrate into the soil so it doesn’t flood. The water that has entered or traveled through these bioretention planters has now been significantly cleaned and filtered to remove pollutants, trash and leaves and will keep them from entering or clogging up the storm drains which lead directly to your local creeks and lakes.

Planters can be installed nearly anywhere in the right-of-way, including in the sidewalk, in medians and pedestrian boulevards, or along the property line of residents or businesses. Although there are many new devices people much smarter than myself have invented that filter stormwater, the natural solution of having plants and soil filter the pollutants has typically come out on top as the most efficient. So, if you ever have the opportunity to observe a bioretention planter in the sidewalk and want to flex your knowledge to your friend who thinks it’s just a regular planter, go ahead and geek out.

Enjoy pollinators in your garden, Avoid Neonics

Neonics is a common pesticide that is harmful to bees, butterflies, and other pollinators.

So, what are neonicotinoids?

Neonicotinoids (neonics for short) are one of the most commonly used pesticides for gardens. They are effective against harmful pests, easily applied and relatively safe for humans. However, what you may not know is that they are highly toxic to beneficial non‑targeted organisms such as pollinators, beneficial insects, birds, and other important organisms. No pesticide is risk free, even eco-friendly pesticides. However, neonics pose a greater risk because of their persistence and staying power within the environment.

Neonics are systemic pesticides, moving though all the plant’s tissue, accumulating in the leaves, the flower pollen and flower nectar. Neonics can be applied as soil drenches, foliar sprays, and tree injections. The most common for the home gardener are the soil drench products with the active ingredient of imidacloprid.  These pesticides persist in the plant for months, and even years once applied. They are commonly used on lawns to combat grubs and other lawn pests, on ornamental flowering plants, like roses & perennials to eliminate aphids and other flower pests, and for trees, including fruit trees.  These neonics not only kill the intended problem pest but are also directly linked to pollinator mortality.

Bees are extremely sensitive to these pesticides. The pesticide remains present in the pollen and nectar of the flowers. Foraging bees are exposed, which impairs their ability to navigate and damages their immune systems.  Bees in the hive that consume collected pollen containing neonics have reduced reproduction rates, and population decline. For butterflies, the risks are similar. It is documented that Monarch larvae died within 7 days after feeding on leaves of milkweed that had been treated with the neonic imidacloprid per the label’s application instructions. For birds, they are exposed to this lethal pesticide when they consume the seeds from treated plants and when hummingbirds drink the nectar. Ladybugs and other beneficial insects are also killed by the exposure to neonics.

Neonics are designed to be a durable and long-lasting pesticide. They are water soluble which allows them to move through the soil during a rain event, making it possible to be absorbed beyond the area where they were applied, exposing wildflowers and other plants. Neonics make their way into the ground water and waterways.

Continued applications of neonics create a toxic environment to all insects, good or bad, directly weakening the ecosystem in your garden.

A less toxic approach to pest management – Alternatives to Neonics

Proper pest identification is key. If we can’t identify the pest then we won’t be able to correct the pest problem. Once we identify the pest, we want to understand it’s life cycle, perhaps we don’t have to take any action if the pest’s lifecycle is completed.  Get curious to see if there are any beneficial predators around that may be taking care of the pest for us. If we need to use a pesticide, then chose the least toxic possible.

For example, lawn grubs are combated by applying beneficial nematodes to the turf. Beneficial nematodes are non-toxic microscopic worm like organisms that feed on soil dwelling organisms. You can purchase beneficial nematodes at your local independent garden center.  Aphids are easily removed by wiping them off by hand or syringing them off with a spray bottle of water. Insecticidal Soap is the best choice if you are looking for an eco-friendly pesticide.

Creek Week 2021 – Ways to Get Involved with Protecting Our Creeks

September marks several dedicated efforts throughout California that signify the importance of clean water and promote cleanups of local waterways. Pollution Prevention Week, Creek Week, and California’s Coastal Cleanup Day all coincide in the third week of September to encourage public participation in keeping our water free of harmful pollutants, with a primary focus on removing trash from local waterways.

Each September cleanup event is organized to bring volunteers together to clean up trash and debris from beaches, rivers, and creeks, to educate the community on the importance of clean water, and to promote an overall appreciation of our environment, nature and being outside.

Make an impact by participating in Creek Week and Pollution Prevention Week. Here are some of the ways you can make a difference.

  • Join a hosted cleanup event or attend an educational webinar. For a list of events, visit Check regularly for updates.
  • Pick up litter and trash near your home, neighborhood, or local creek. Trash and litter in the environment can end up in our waterways either directly or through the storm drain system. When it rains, trash can enter the storm drain system, which moves water from paved areas to local waterways. By picking up trash you can help prevent trash from ending up in our local creeks, the Russian River, and the ocean. Even if you don’t live near the Russian River or the coast, your efforts will make a difference in protecting our water resource.
  • Start a compost bin. Need help getting started? Check out our RRWA article archive  or watch tutorials at
  • Discontinue pesticide and herbicide use in your garden with safer alternatives. Our Water, Our World helps residents manage their home and garden pests in a way that helps protect our watershed. Learn more here
  • Dispose of unwanted household hazardous waste (HHW) responsibly. Check your local HHW Collection facility for events: Sonoma County Mendocino County
  • Pick up pet waste.
  • Pick up leaf litter and yard waste to prevent it from clogging the storm drain.
  • When washing your car, don’t allow wash water to enter the storm drain.
  • Drop off unused and unwanted medications at a safe medicine disposal location. For location information visit

Show us your impact! As a way to show your participation, log cleanup efforts using a trash collection app.  Some options are Litterati – The Global Team Cleaning the Planet and CleanSwell – A Global Movement to Keep Beaches, Waterways and the Ocean Trash Free. By entering the amount of trash collected and the location collected, you can help us record the success of Creek Week volunteers.

These are just some ideas how you can help protect the environment. For more information on these and other ideas visit the Russian River watershed website at Remember, September signifies the designated month to promote the importance of our local rivers and creeks, but these ideas to protect the environment can be implemented all year long.

Safe Medicine Disposal Program Update

How do you dispose of your old prescription and over the counter medicines? Not only are there environmental concerns associated with throwing medicine in the trash and flushing them down the toilet, letting them accumulate at home creates opportunities for those medicines to get into the wrong hands. For these reasons, the Russian River Watershed Association (RRWA) enacted the FREE Safe Medicine Disposal Program to safely take back and properly dispose of unwanted medicines.

The Safe Medicine Disposal Program is a partnership between local agencies, pharmacies, and law enforcement offices to safely dispose of unwanted medications, prevent overdoses, and protect the environment. Residents of Sonoma and Mendocino Counties can drop off their unwanted medications at free, discreet, and anonymous medicine take-back locations. These locations accept prescription and over-the- counter pills and capsules, liquid medications, veterinary medications, vitamins, supplements, homeopathic remedies, medical patches, inhalers, and medical samples. Since 2007, the Safe Medicine Disposal Program has collected over 142,100 pounds of unwanted medicines. For more information on the Safe Medicine Disposal Program locations, visit

In addition to the Safe Medicine Disposal Program, Sonoma and Mendocino County residents can use the following free medication disposal programs:

  • The California Drug Take-Back Program is funded by California Department of Health Care Services’ MAT Expansion Project and developed and administered in partnership with the California Product Stewardship Council.
  • National Prescription Drug Take Back Days: Dispose of medications, including controlled substances, at special one-day collection events sponsored by the Drug Enforcement Administration (DEA). The next event is October 23, 2021 – 10AM to 2PM.

Syringes and needles (also known as sharps) have fewer drop-off locations due to safety and regulatory concerns and are not accepted at many of the Safe Medicine Disposal drop-off locations. State law makes it illegal to dispose of sharps in the trash or recycling containers and requires that all sharps waste be transported to a collection center in an FDA-approved sharps container. Please refer to the provided list of certified sharps and needles disposal locations within Sonoma County and Mendocino County to properly dispose of the collected sharps found at Contact your local household hazardous waste facility, local law enforcement agency, public works, or parks department should you need further assistance disposing of sharps.

More sharps disposal information can be found on these websites:

More options for safe and convenient medication and sharps disposal will be available in 2022 with the implementation of the Senate Bill (SB) 212 (Jackson, Chapter 1004, Statutes of 2018). This law is an extended producer responsibility (EPR) law, requiring that pharmaceutical manufacturers manage their products’ waste at end-of-life. To comply with this law, pharmaceutical manufacturers and others in the product chain will design, manage and fund take-back programs to securely collect unwanted medicines and sharps waste from the public and ensure the collected materials are properly managed. More information can be found here: Stay tuned for updates from RRWA on this new statewide program.

Recycling Your Used Motor Oil and Filters Helps Our Watershed!

The Spring and Summer seasons bring us a display of colors and beautiful landscapes. Similarly, these months of hot weather invite us to make improvements in the house, to work in the garden, or in the case of many Do-It-Yourself Oil Changers and auto enthusiast, this is the perfect time to change the oil and filters in their cars. This is an important reminder that an oil change is not finished until the used oil and filters have been properly recycled.

Used motor oil is a hazardous waste that should never be discarded in trash, poured into storm drains, or dumped into the ground. If you do accidentally spill oil on the ground, stop and clean it up before it enters a storm drain. Because there is no treatment system inside the storm drains, everything that enters the storm drain system flows directly into our creeks and the watershed, including used motor oil. A single gallon of used motor oil can contaminate one million gallons of water creating health risks and generating environmental impacts that can affect our entire community. In addition, it is illegal to pour used oil on the ground and you may receive some fines by discarding it incorrectly.

Recycling used motor oil and filters is the only safe way to discard it. It is also easy, convenient, and free. Oil and filters can be recycled at collection centers in Sonoma County, it can be collected on the curb and can also be collected at the Household Hazardous Waste Collection Facility. Choose the option that is the most convenient for you!

Recycle Your Used Motor Oil and Filters at a Collection Center

Collection centers are local companies that accept used motor oil and filters during their customer service hours. There are nearly 50 collection centers in Sonoma County, and they accept the used oil and filters for free. Some sites even offer a 40-cent rebate per gallon of used motor oil collected. These sites typically accept up to 5 gallons of used oil and two filters per visit. Collection centers in Sonoma County can be found by visiting and you can visit CalRecycle’s website ( to find locations in Mendocino County.

It is important to remember never to mix the used motor oil with any other material (including water, solvents, or gasoline). These sites will not accept contaminated oil, which causes their used motor oil to become non-recyclable, and it is very costly to clean contaminated tanks.

Take Advantage of the Curbside Used Motor Oil and Filters Recycling Program

This option is only available for single-family homes; apartment complexes do not have this service. Curbside used motor oil and filter recycling is available in all cities and in the unincorporated areas of Sonoma County. You are encouraged to call your local hauler for details and to order this service. Town of Windsor residents can call Sonoma County Resource Recovery at (707) 795‑7470 to get more information. Recology Sonoma-Marin garbage collection provides curbside collection to the rest of the County and unincorporated areas, and they can be contacted at (800) 243‑0291.

When you are ready to recycle your used motor oil and filters using the curbside used motor oil recycling option, pour the used oil inside the container provided by your collection company, and put the drained filter in a Ziplock plastic bag. Then, place the oil container and the filter next to the recycling bin the day of your weekly collection. The hauler that serves your area will collect the used motor oil and filter and will leave you an empty container for you to use for the next oil change.

Recycle Your Used Motor Oil and Filters at the Household Hazardous Waste (HHW) Collection Programs

Zero Waste Sonoma’s Household Hazardous Waste Collection Facility ( is conveniently located at 500 Mecham Road in Petaluma for Sonoma County residents. This site accepts up to 15 gallons of used motor oil per visit and also accepts the filters. This is the only place that can accept contaminated used motor oil, but you should inform the staff when you arrive. Apart from accepting used motor oil and filters, the HHW Facility also accepts other hazardous wastes including fluorescent lamps, paints, solvents, paint thinners, adhesives, pesticides, batteries, and other engine fluids to name a few The facility is open Thursday-Saturday 7:30am-2:30pm for free drop off from Sonoma County residents. Zero Waste Sonoma also provides free HHW Collection Events every Tuesday evening at a different location across Sonoma County and offers an HHW Rover pick-up program for a small fee (

Similar programs are offered to Mendocino County residents by Residents can bring used motor oil and filters to their Household Hazardous Waste Collection Facility at 3200 Taylor Drive in Ukiah and they also provide frequent HazMobile HHW events throughout the county.

If you are one of those Do-It-Yourself oil changers that will be working on the car this summer, please remember that the oil change is not complete until the used motor oil and filters have been recycled. No matter what part of the county you live in, there are convenient and free used motor oil and filter recycling options near you. Visit,, or call Zero Waste Sonoma’s Eco-Desk at 707-565-3375 for more information.

Eight Water Conservation Tips and Tricks

On average, each Californian uses about 85 gallons of water every day, but it depends on the season. In winter months, it’s as low as 60 gallons per day and in summer months, it’s as high as 110 gallons per day. That’s between 12 and 22 of those 5‑gallon water cooler jugs, every day for every person! About a quarter of that water literally gets flushed down the toilet. More than half comes from faucets, showers, and appliances.

Efficient water use is always important, but it’s imperative right now. The drought will pass, and rain will come again, but right now, in this moment, we have a civic duty to do what we can to help. Our local rivers, water suppliers, and various sources of fire protection water need each of us to do our parts to make sure there’s enough of this valuable resource to go around. There are countless ways to easily save water and save money while doing it. Here are some water conservation tips and tricks.

  • Look for and fix leaks. Dripping faucets and worn toilet flappers are common types of leaks found in the home:
    • Check your water meter, wait a few hours without using any water, and check your meter again. If your meter changes, you probably have a leak. Be careful lifting the lid to your meter, as wires can be connected from the lid to the meter that are expensive to replace. Information about your water meter can be found at
    • To find a leak in your toilet, place a few drops of food coloring in the tank and wait 10 minutes. If color shows up in the bowl, you have a leak.
    • Examine pipes and valves under your sinks to check for moisture.
    • Check your irrigation system regularly to look for leaks and make repairs promptly.
    • Don’t forget your
    • garden hose. If it leaks at the spigot, replace the hose washer and ensure a tight connection with pipe tape and a wrench.

Fixing household leaks can save you about 10 percent on your water bill. While you’re at it, see if you can find a leak at work and report it to maintenance staff. If you see an irrigation leak around town, report it to the local utility.

  • Fix the flush. In general, the older your toilet is the more water it uses. Toilets built before 1982 use 5 to 7 gallons per flush. Toilets built between 1982 and 1993 use about 3.5 gallons per flush. Newer toilets use 1.6 gallons of water or less. For the average flusher with an old commode, that’s a savings of about 20gallons per day or 600 gallons per month per person! Look inside the tank of your toilet for a date stamp either on the inside of the tank near the top or on the underside of the tank’s top. Try flushing less. “If it’s yellow, let it mellow. If it’s brown, flush it down.” Never use a toilet as a garbage can.
  • Take shorter showers, or fewer showers. You probably aren’t THAT dirty anyway. Challenge yourself to take a 5-minute shower. Replace your showerhead. There are many low-flow options out there for just a few bucks. The average family could save 2,700 gallons per year by installing more efficient showerheads. Hot water savings reduce demands on water heaters, saving energy dollars too!
  • Save water at the faucet. Replacing faucets with low flow options can reduce water use by as much as 30 percent or more without sacrificing performance. Not ready to replace a faucet? Try adding a low flow faucet aerator. They’re small, inexpensive, easy to install and can reduce faucet flows to 1.5 gallons per minute. A family can save about 700 gallons of water per year by installing an aerator. Turn off the water while you brush your teeth, wash your hands and shave. Use a machine dishwasher if you have one and avoid pre-rinsing dishes. Machine washing generally uses less water, energy, soap, and time. If you must manually wash dishes, always use a basin to soak and scrub dishes and be quick with rinsing. Try not filling up the basin. Rinse out recyclables in the dishwasher, with dirty dishwater or wipe them clean with a gently used napkin. Reducing demands on hot water saves energy too. If you’re in the market for a new appliance, toilet, faucet, showerhead, or faucet aerator look for the WaterSense label. This is a distinction earned by meeting EPA water efficiency criteria without compromising the quality of your fixture experience.
  • While you wait for water from your bathtub and sinks to warm up, try catching it in containers like milk jugs or buckets. Use the water you collect to water plants and make coffee. You can also use it to flush the toilet by dumping water into the bowl with one quick pour into the bowl to create a strong flush.
  • Generate less laundry by wearing clothing multiple times if they’re not dirty and reuse your bath/shower towel for an entire week. Only run appliances when you have a full load for washing. Try air drying dishes instead of using a dishtowel.
  • Let your lawn go brown. Or even better, explore alternative landscaping and irrigation options like rock gardens, native and drought tolerant plants, rainwater harvesting and other long-term options. Add 2” -3” of mulch to help retain soil moisture. If you must irrigate, do it at night or in the early morning to minimize evaporation. Make sure you have a garden hose nozzle with an auto-off lever so you can target plants and avoid spraying everywhere. Landscaping should survive, not thrive in a drought. Use a broom or blower to clean surfaces instead of hosing them off.
  • Don’t wash your car. If you can’t stand a dirty ride, wash your car at a commercial carwash. Many facilities recycle their wash water, but even if they don’t, car washing equipment is much more water efficient than your garden hose. Avoid washing your car at home.

Keep Our Cars and Our River Clean

Clean Car, Dirty Creek

Common sense tells us that you can’t get something clean without getting something else dirty. Depending on how you wash your car, you may be trading a clean car for a dirty creek. The dirt, oil and grease that flows off your fresh clean car often flows into the street, storm drains and then into our creeks. This water does not get treated at the local sewage treatment plant. When we wash our cars in our driveways, the dirt, oil and grease from our cars hitch a ride with the water and soap and flow into street gutters. Eventually, all those pollutants reach the Russian River.

The Power of One, Multiplied

If you’re thinking that washing your car couldn’t possibly hurt the fish in our waterways by itself, you’re probably right. But with the nice weather, you won’t be the only one making your ride gleam; lots of neighbors will be washing their cars too. All the dirt, oil, grease and soap will collect in the storm drains and wait for the next rainstorm. These pollutants do not evaporate, so they can collect all Summer long. When Winter returns, an entire Summer’s worth of pollution is flushed into our creeks and the Russian River all at once.

Take a BreakThe good news is that there are things you can do to reduce the environmental impact of washing your car. If you hand wash at home, try washing your car on an unpaved part of your yard and let your landscaping clean the wash water for you. When you wash your car on your lawn or other unpaved area, the pollutants you rinse off your car will saturate into the soil. The soil, gravel, and vegetation act as filters for the soap and grime.

The easiest way to wash your car is also the most environmentally friendly; have your car washed at a professional car washing facility. Most professional car wash facilities collect and re-use their rinse water. When done, they then discharge their dirty water to the sanitary sewer where it gets treated. Professional car washes also reduce water usage and support local jobs. You can take a break from washing your car and give our creeks a break too. A list of the “greenest” car washes in Sonoma County is available here:

Fundraiser Car Washes

A community car wash is a traditional way to earn money for scouts, schools, or sports programs. Unfortunately, it also concentrates a lot of dirt, oil and grease in one location and then puts it all into storm drains (and eventually creeks) at once. If you are a planning a community car wash on a paved area, plan to block the storm drains receiving the rinse water and pump the accumulated rinse water into a sanitary sewer inlet, or direct the water to a landscaped area where it can soak in. Before planning a fundraising car wash, please call your local municipality for the latest requirements and guidelines.

With a little effort, we can each keep our cars gleaming while protecting our creeks. Clean cars don’t have to mean dirty creeks.

D.I.Y. pesticides…. Are they safe?

I was on a call with a friend the other day. She just happened to mention how she has been spraying newly developing weeds growing in the cracks of her walkway with the widely popular vinegar, dish detergent and salt recipe. Wonderful that she was getting a jump start on the young weeds, since the best time to manage them is when they are newly sprouted. However, unfortunately, this internet recipe that has been trending does more harm than good.

Don’t get me wrong. I appreciate the sincere intentions to reduce pesticides, but this recipe is a huge concern and very much misunderstood.  Here’s the deal:

  1. Dish detergents are not true soaps. The only true soap on the market is castile soap, under the brand name of Dr Bronner’s and the Whole Foods 365 brand. I’m sure there are a few more, but not always easy to find. Unlike true soap, dish detergents contain many harmful additives, such as:
    • Methylisothiazolinone: is highly corrosive and found to be toxic when ingested or inhaled, it also causes skin irritation/allergies/damage, and causes acute aquatic toxicity
    • 1,4-Dioxane: is listed as a likely human carcinogen, and a groundwater contaminant
    • Ethanolamine: is listed as harmful if swallowed, including respiratory effects, general systemic/organ effects, chronic aquatic toxicity, nervous system effects, skin irritation/allergies/damage.
    • Triclosan: is listed as causing developmental/endocrine/reproductive effects, cancer, immune system effects, circulatory system effects, nervous system effects, skin irritation/allergies/damage, digestive system effects, and having acute aquatic toxicity

And that’s not all, many have words like ‘natural’ on the label but have added scent and coloring that are chemicals showing health concerns. So, when we use these types of dish detergents as an additive in our D.I.Y. weed killer or aphid spray, we are doing more harm than good, contaminating our soils, our plants, and even ourselves.

  1. Salt is bad news for your garden! Salt in the soil absorbs water, reducing the plants ability to take up water, increasing root dehydration. You might think this is exactly what those weeds need! However, keep in mind that if you ever want to plant in that soil, you may see your plants struggle, even die because of this salt build up. Let’s look back at our history books, remember how the Romans, and other invading armies, would burn a village down, then salt their fields to prevent them from growing crops again? Avoid adding salt to your soil if you want to grow lovely plants (this includes using synthetic fertilizers, which are very high in salts. Feed your plants organic fertilizers for optimum health).
  2. Vinegar, here’s the deal: Household vinegar is diluted to about 5% acetic acid vs horticultural vinegar which is around 20% acetic acid, which is pretty strong. Understand that 11% acetic acid can burn skin and cause eye damage, while concentrations of 20% or higher can cause blindness and are corrosive to metals. This is no joke! Something else to understand is when vinegar is used as a weed killer/herbicide, it is working as a ‘top kill herbicide’, killing the top ‘leafy’ portion of the plant tissue. This is why when using many of the eco-herbicides that are sold on the market, is it is best apply when the weeds have just sprouted so that the root will not be able to recover and sprout new growth.

Our Water Our World logo

So, what is the best way to kill weeds? Hand pulling weeds, using weeding tools, and sheet mulching (layers of overlapping carboard with 3” of mulch on top) can’t be beat for best ways to manage weeds. However, if you are still wanting to use a D.I.Y. method then I’ll share a little trick, you can kill many weeds with boiling water! That’s right, boiling water! So, boil up a kettle of water, grab your oven mitt, use caution to not burn yourself and douse those weeds. Just like the D.I.Y. recipe, you will most likely need to repeat this as needed, but without the cost or the potential harm.

Save Water As If Your Life Depends On It

“Every drop counts.”
“Use water wisely.”
“There’s never enough to waste.”
“Our future in every drop.”
“Save water, rain or shine.”

Those of us in the water industry are always looking for new ways to ask our customers to save, conserve, and never waste water. And we do that for good reason. We live in a region prone to regular periods of drought, punctuated by sudden and catastrophic floods. Last year we had a very dry year, and this water year is off to a very dry start as well. Sonoma Water, which supplies drinking water to 600,000 residents in Sonoma and Marin counties, relies on rainfall to fill our reservoirs and consecutive years of below-average rainfall are always cause for concern. Will this be a two-year dry spell, or the beginning of a multi-year drought?

Given the current conditions (as this is being written in January) there is a good chance you’ll be hearing from the Sonoma-Marin Water Saving Partnership this winter and again in the spring and summer about your water‑saving habits. It could also happen that by the time you read this we will have been drenched with a series of soaking storms and all the hand-wringing about a second dry year and low reservoirs will be a moot point. But what if it’s not?

This is the dilemma local water managers face on a regular basis. We live in a place prone to drought, sometimes long and painful droughts. We’ve experienced enough dry years to know that we can’t wait too long to sound the water-saving alarm.

Complicating the issue in the Russian River watershed are the threatened and endangered fish species, and the requirement to coordinate releases from our two reservoirs, Lake Mendocino and Lake Sonoma, to provide enough water for migrating salmon. It’s a complex equation that adds another layer of peril to the balancing act. Our water scientists are adept at navigating an array of requirements and demands, both political and regulatory, in order to balance the needs of many competing interests.

On a more positive note, a team of scientists from Sonoma Water, the Center for Western Weather and Water Extremes at Scripps Institution of Oceanography, U.S. Army Corps of Engineers, National Oceanic and Atmospheric Administration, U.S. Geologic Survey, U.S. Bureau of Reclamation and the California Department of Water Resources, have successfully proven the viability of a program that allows more winter rain to be stored at Lake Mendocino using advanced weather forecasting. The program, known as Forecast Informed Reservoir Operations (FIRO),balances the water supply and flood control purposes of the reservoir and is being considered by other water agencies in the state. FIRO holds great promise as a new tool for preserving our water supply while reducing flood risk.

The wild card in this discussion is climate change and the profound changes it is expected to have on our water cycle. Will it lead to longer droughts and more intense storms? Probably. Will we have warmer temperatures and increased pressure on water supplies? Probably. Will this mean that water will become even more precious and the need to save water and use it wisely even more critical? Certainly.

Our local water systems are complex and rife with uncertainty. One thing that we do know for certain, however, is that we cannot afford to waste water. Our lives really do depend on it. So, when we ask our customers to save water – no matter which words we use – we mean it.
