World Water Day: Take Action With Home Water Conservation

In 1993, the United Nations designated March 22nd as an international day of observance for countries and individuals to consider the water conservation issues that impact our lives. Think about whether some of these great water saving measures might be right for your home:

Graywater Recycling: Rethinking Bathroom Design

Imagine a simple design change that could save between 3,650 and 7,300 gallons of fresh water every year in your household alone. That’s the average quantity of water that goes down your bathroom sink’s drain annually. A graywater system, in which waste water is filtered and then reused for the toilet, can save these gallons from being wasted.

Graywater bathroom fixtures are no longer hard to find, but they still tend to focus more on function than on form. There are adapter kits that can change a standard plumbing arrangement and connect the sink to the toilet, but these can be clunky affairs.

However, now there are options that combine style with green features. Integrated toilet and sink fixtures (like the unit pictured above from Spanish manufacturer Roca) are a nice streamlined effort, albeit at a steep price. An automatic cleaning system prevents bad odors and bacteria, while a specialized tap controls the water’s temperature and flow for maximum energy savings.

As these options come down in price and become more available, they’ll make it that much easier for consumers to  green their homes without having to settle for a product they find unappealing. As more green products enter the market, choice will give all consumers more incentive to go green.

Monitoring drought conditions

Saving water is always a smart move as a way of lowering your utility bills. However, for some places in the U.S., drought conditions make water conservation even more important as a part of efforts to preserve and protect our water supplies. Droughts are especially difficult situations for states and localities to handle, since there is often little warning before their onset, and they generally last much longer than other natural hazards like floods or hurricanes.

How can you tell if your area is undergoing a drought? The National Drought Mitigation Center posts regularly updated national drought maps searchable by region and state. The map can be found at this link: http://www.drought.unl.edu/dm/archive.html.

If you are in an area with drought conditions, consider contacting your local Eco-Consultant to learn about water conservation steps you can take, as well as about local water conservation campaigns and programs.

Water Conservation: Little Steps = Big Rewards

Most people don’t think twice about their water bill until they start watering their lawn in the summer.  Compared to other utilities water is very inexpensive for the end consumer compared to their natural gas bill in the winter, or their electric bill in the summer due to running the air all the time.

When it comes to our fresh water from the tap have you ever thought of just how much time, money and energy it takes to deliver that water to you?  Just running your kitchen tap for five minutes can cause your local water treatment plant to use enough energy to light a bulb for 8 hours!

Last year we decided to take a look at our water usage in our home.  First stop, faucets.  We noticed our faucets were running 2 gpm (gallons per minute) or higher.  We swapped those out with 1½ gpm aerators.  Next, the toilet. It is an older model with that runs 4 gpf (gallons per flush), but we never thought about replacing the toilet. Quite honestly, when a toilet breaks it’s usually a trip to the local hardware store and $20 later it’s fixed.

Instead of replacing we decided to give some products a try.  We used the Green Irene Fill Cycle Diverter and the Toilet Tank Bank.  I also had an adjustable flapper that I had purchased previously but never installed.  After installing these toilet items, our toilet now flushes and refills faster than I ever thought possible.

We didn’t replace the showerhead at that time; we couldn’t decide what model to go with.  The next month our water bill came and I couldn’t believe it.  With just $20 and a commitment to ourselves to use our water smarter in our home, we reduced our consumption and waste water by an entire unit!  That’s 800 gallons!  This was during non-watering months so it was probably the best data we could ask for in our test. 

This is just an example of how all the little things add up around your home. On average, over the past year our utility bills are a combined 20% lower just by implementing some Green Irene tactics on top of what we considered already “Green.”

Is Your Yard Permeable?

If you poured a five-gallon pail of water into the middle of your yard, where would that water go? Would it pool up? Would it run towards the street? Ideally, if your yard has the right amount of permeability, the water would slowly soak into the ground.

Permeability refers to how quickly water moves through layers of soil, sand, and rock. For example, consider the hard-packed soil of a playground (or your back yard in a drought!). It’s nearly impervious; water runs off of it as it would from cement. At the other extreme, there is the limestone karst country of southeastern Minnesota. Water rushes down through the cracked and water-worn rock, joining the underground water supply with a minimum of filtration. Karst is highly permeable; contaminated liquids applied to the surface flow directly into the ground water.

Ideally, water seeps slowly into the ground, where it is filtered and cleaned by layers of humus, soil, sand, and gravel. Water that lands on impervious surfaces such as parking lots, roads, and large, flat roofs tends to flow directly into nearby lakes and rivers (usually via gutters and storm sewers), carrying with it a wide variety of contaminants, from motor oil to pesticides.

Between 1986 and 2000, impervious surface in the seven-county metro area increased 60 percent. The more parking lots and developments there are, the more wetlands that are filled in, and the wider our highways become, the more water runs off the land and directly into lakes, rivers, and streams without having any of its impurities removed.

To see for yourself how permeability affects water quality, visit the Minnesota Landscape Arboretum. Water from five mini-watersheds, each using different types of pavement, flows into holding ponds. You can walk by each holding pond and see the difference in water quality.

As people are becoming aware that water should seep into rather than run off of the land, gardening and construction techniques are changing. Rooftop gardens are becoming popular; they absorb rainwater that otherwise would run down drain pipes and into the storm sewer. Some businesses and homeowners are using pervious pavers instead of tar or cement for parking lots and driveways. (Remember city streets made of paving stones? They were much better for the environment!)

Some communities are building rain gardens alongside roadways instead of constructing curbing that funnels rainwater into drains that run to the river. Like wetlands, rain gardens hold and absorb large amounts of run-off, and clean the water before it gets to the river.

What can you do to prevent rain water from flowing out of your yard and down the storm sewer? We’ve talked about a rain garden, but our yard, likemost city lots, is too small. A rain garden needs to be located a certain distance away from one’s basement. However, we could shore up the soil in front of the house, where the lawn slopes down to the sidewalk. We could use mulch to keep garden soil moist, so that less water runs off during a hard rain shower.

I’d like to buy pervious pavers for our driveway. My partner says, “But we already have a permeable driveway.” It’s sad but true. Now that the city inspectors are no longer preoccupied with the hazardous sunflowers we had draped over the back fence, I’m afraid they will notice the healthy crop of weeds pushing aside disintegrating chunks of tarmac behind our garage. Rainwater hitting our driveway doesn’t run off; it sinks through those cracks and gets cleaned and filtered by layers of earth, just like it’s supposed to. But I have to say, that’s one ugly permeable surface!

Next time it rains, grab a raincoat and observe the patterns of absorption and run-off in your yard. Then start thinking of ways that you could encourage rain water to stay in your yard and be absorbed by the soil. Maybe you don’t need that solid cement patio now that the kids are grown. If your driveway is due for a facelift, how about paving stones rather than tarmac?

There are dozens of ways you can insure that rain water goes through your soil rather than directly to the storm sewer. Here are some links:

5 Reasons To Conserve Water

Water has become one of the biggest environmental issues of our time. Over the last few years, it has become more and more clear that water supplies are diminishing and that to secure freshwater for future uses, we must make great strides to conserve water today. Green Irene offers many ways for homes to save water, from simply providing Green Home Makeovers to determine near-maximum to maximum water-saving potential to selling products that can help you dramatically cut water use while saving money.

To further show why we should be doing the most we can to conserve water, check out the 5 reasons we’ve outlined below.

1. Money. As you use water in your home to brush your teeth, shower, or do anything related, you are likely using heat to warm your water. Undoubtedly, this heat costs money, and so it is in people’s interest to save money on water by conserving it.

2. Greenhouse gas emissions. Similarly, when you use energy to heat water, you are likely contributing carbon dioxide emissions as a result of the combustion of natural gas. While there isn’t yet a cost to emitting carbon dioxide, the principle gas that is causing global warming, there will eventually be one as a result of climate change regulation. Conserving water can help reduce carbon dioxide emissions, and in the long-run will also cut costs related to carbon regulation.

3. Wildlife. In water-scarce regions, like the Southwestern U.S., water is a critical resource for the survival of wildlife. For example, wild salmon runs are highly dependent on the availability of water, and high levels of water withdrawals from water bodies can easily threaten the survival of such species. Recognizing that ecosystems need water as well to function well, it is important to conserve water in order to have sufficient water available for wildlife.

4. Recreation. People might take water-related recreation for granted, but there are many recreation areas that confront water problems as a result of pollution and overuse. Many recreation areas depend on available water to ensure adequate quality and provide sufficient quantities for recreational purposes. Conserving water can help ensure that these needs are met as well.

5. Wastewater treatment. Finally, one of the hidden costs of using water is treating it once it is used. In most cases, whether the water is clean or not, water goes straight to a treatment plant where it must go through a process to ensure its quality is adequate. The more water that has to be treated, the more homes have to pay through taxes in order to meet that service. As a result, conserving water can help reduce your taxes, making money available to spend on other things.

There are many other reasons why homes should conserve water, ranging from water needed for food production and power plant cooling to water from nonrenewable sources being needed for the future. If you want to learn more about how to conserve water, get in touch with your local Eco-Consultant. Also check out water-conserving products at ShopGreenIrene.

Federal Government Orders California To Cut Water Use

Over the last three years, California has suffered from a prolonged drought that has hurt agriculture and stressed water supplies for major urban areas. In addition, the state’s massive system of dams and pipelines designed to turn desertland into productive farmland has further compounded the problem. This has led to a steep decline in the population of wild salmon, trout, sturgeon, and other fish that normally need adequate amounts of water to survive.

As a result of changes in water supplies and their effects on fish populations, the National Marine Fisheries Service has ordered the state to cut its water use by 5-7 percent for cities and agriculture from major water suppliers. This has prompted the state to either cancal requests for water or begin thinking about how to conserve water. In the long-run, the state will have to devise ways to substantially reduce water use.

Green Irene can help Californians meet that challenge. A Green Home Makeover is a simple way of figuring out how to reduce water use in homes. A Green Irene Eco-Consultant will walk you through simple steps you can take to cut water use right away. Usually, this will also mean saving energy and money. For example, by using low-flow showerheads, you can save nearly half of the water used in the shower. This can translate into thousands of gallons per year for every person.

The state has a goal of cutting water use per capita by 20% by the year 2020. In order to meet this goal, homes will have to play a big role in reducing their water use. Let Green Irene get you on the path to using less water without changing your lifestyle. Find your Local Eco-Consultant today and get a Green Home Makeover to get started. Then browse Green Irene’s line of water-saving products at ShopGreenIrene. Water scarcity represents one of the biggest problems of the 21st century, and your role in helping solve it will be critical to society.

Water-Wise Landscaping

As populations grow and droughts occur more frequently across the country, water supplies are becoming tighter and tighter. This has prompted a closer look at landscape watering. Approximately one-half of residential water is diverted to landscape watering, and much of it is needlessly wasted. Fortunately, there are many simple steps that homeowners can take to reduce water waste and get more from the water they use.

The biggest water user in the home landscape is typically the lawn, so it is the area that offers the biggest opportunity for water savings. Here are a few suggestions:

• Reduce the size of the lawn by adding or increasing the size of planting beds, gardens, and patio areas.
• Use locally-adapted turf grasses that have lower water requirements.
• Water early in the day, when wind and evaporation losses are their lowest.
• Water deeply, with less frequency. This reduces runoff, and encourages deep-rooted, resilient grass plants.
• Water efficiently by limiting over-watering, limiting watering paved areas, and using well-maintained equipment.

The opportunities for water-savings continue beyond the edge of the grass. An increasingly popular option is planting native, or well-adapted, drought-tolerant landscape plants. And you don’t have to go for the desert look to pursue this option (although the desert look can be beautiful). There are a wide variety of plants available in most areas that can get by with little or no supplemental watering. Keeping plants healthy also helps by allowing them to be more tolerant of drought stress.

It’s also important to group the plants according to their habitat needs: dry and sunny, shady and moist, or somewhere in between. This way, you can water the plant groups that need it and avoid those that do not, allowing plants to thrive with the amount of moisture they desire.

As with lawns, water can be saved in planting beds by watering slow and deep, efficiently, and early. Low-pressure drip irrigation systems are very effective at achieving these goals, plus they help avoid disease problems plants can develop with sprinkler irrigation systems.

Another water-saving tip for landscape beds is to use mulch. Mulch, most commonly wood chips or bark, help hold the soil moisture in, plus it moderates soil temperature extremes. As the mulch decomposes, it adds organic matter to the soil, improving water penetration and holding capacity.

The ultimate in water savings is to capture it for reuse later. Options range from the simple 55 gallon drum at the base of one or more downspouts, to more involved high-capacity cistern systems. Either will help you put to good use water that otherwise would be wasted as runoff.

For the most part, these steps are not difficult or complicated. Taking these steps will allow you to have an attractive, diverse landscape on a low-water budget.

Is Your Water Filter Getting All The Bad Stuff Out? A Green Irene’s Story

In New Jersey American Water’s 2008 report for Somerset County and surrounding counties, drinking water met all standards. Unlike in 2007 (see my previous blog post) there was no detectable tetrachloroethylene and only 0.6 ppb of tricholoroethylene. NJAW reported levels of manganese and sodium higher than the MCL, though this is not generally considered a health issue, as our bodies need these nutrients. NJAW also sampled 51 homes. In one home, they found excessive levels of lead, and in one they found excessive copper (both from plumbing in the home).

After reading the 2007 water quality report, I was concerned. I ordered a water testing kit online. I sent in water samples and got my water analysis report within a couple of weeks. The test detected acetone in my water, at a level of .08 mg/L. There is no national standard for the amount of acetone allowed in drinking water, so NJAW does not have to report it. Low levels of chloroform and bromodichloromethane were also detected, but these were at acceptable levels. The test also detected acceptable levels of minerals, and determined that we have hard water (which I already knew).

Trichloroethylene, tetracholorethylene, and acetone are VOCs (volatile organic compounds). Given all of these questions about the quality of my water, I decided that I needed to upgrade my water filter to make sure that it removes all VOCs! Note that our local hardware stores do not carry good VOC filters. The only VOC filter I found locally was at Home Depot, and it was expensive and only worked for 60 gallons of water! I found my VOC filter by looking on my water filter system for the brand of the system, then searching the internet to find the model number for their VOC filter, then searching for that filter. A good option was Green Irene’s sink-top water filter, which filters out VOCs plus many other harmful chemicals.

Last week, peer-to-peer network CurrentTV invited us to participate in their Earth Week special, where they asked their readers to pose their most burning eco-questions to a handful of savvy bloggers. We’ve been thinking a lot about the state of the world’s water lately, so this question stood out to us:

It’s always considered a major no-no to waste water. But how is water used in a household wasted? Isn’t it all just processed and reused?

I understand that there is energy spent in processing and there are possible chemical issues in the cleaning process but I’m really just interested in the whole concept of “wasting water”.

What percentage of water that goes down the drain is actually lost forever?

– Jakebot

Great question, Jake. We want to answer this question for you in two parts: simple and not so simple. First, the simple answer to your question is zero. Zero percent of water that goes down the drain is actually lost forever because, according to the law of conservation of mass, matter cannot be created or destroyed.

But what you want to know, then, is, ‘why is wasting water is such a big no-no?’ The answer to that is cost and location. In the United States, most people get their water from wells or from municipal systems. Once they’ve used it, most people send their “waste” water down the drain to either the wastewater treatment plant or to a septic system. It is costly — in terms of both money and energy — to transport water from its source to our houses, and to treat it once it leaves our houses.

Location is a big deal when it comes to water. If you live in Seattle, like we do, it’s plentiful enough that we don’t need to worry too much about wasting it because there is always enough for all of us to use as we please. But in most places, water still goes through a natural cycle — either evaporating or soaking into the ground — before being taken back into the municipal system. So in cities that suffer from drought, there is not enough water in the public system for everyone to use all they want, all the time, and it becomes even more apparent why sourcing water from a reservoir many miles from your home, and flushing it to a location just as far away, is a massive dedication of resources for a system that could be handled more locally.

The costs of operating these systems are growing every year. As Carol Steinfeld, author and founder of Ecovita told us (we asked for her input to help answer your question), “we have more people on the planet, each using more and more water, than ever before in human history.” So, to provide the basic human right of clean water for all, it becomes imperative that we get more efficient at using our water. When you think about it that way, it seems very wasteful to use clean drinking water to wash our cars water plants, or spray the sidewalks — when water re-used once, twice or even three times from relatively clean places like the shower, the sink or the washing machine, would work just as well without requiring nearly as much energy.

Making our water systems more efficient means we need to implement some of our more innovative solutions to reusing and treating our water at the source, such as the super-treatment facilities in San Diego, home rainbarrels, or even Steinfeld’s waterless toilets. If we can get better at cutting the external cost of providing clean water — treatment and transport — then we can build a system where water isn’t waste, but a resource.
