Rain Shout: high volume = high pressure

We curse the sky when there is drought. Then we rejoice, and bathe, and blow kisses to our plants upon the rainfall. Now that we think about it, doesn’t it seem logical to be able to reap the benefits of that oh-so-delightful rainfall for weeks following? Since I’m not here to preach doom and fear, I’m going to tell you that you can lengthen that rainfall benefit, and also why you simply can’t pass up the opportunity to do so. As a result, the environment, your plants, the gutters, and those pipes down at the water treatment plant will thank you!

Maintaining the “perfect” vanity lawn can place a high demand on our environment, our health, and our municipal utility grid. Residential communities tend to guzzle 40% of their water consumption on irrigation in a given municipality. When cities like Chicago processes 1 billion gallons of water every day for general consumption, we wonder how much we could ease this demand if we had an alternative water source for our grass and plants.

All you need to do is divert your gutter to spill into anything that will hold a large volume of liquid over time. The most common way of collecting rainwater is in a rain barrel, which is commonly made from a 50-gallon food drums. The average roof and gutter system has the capacity to fill a 50 gallon drum with only ¼ inch of rainfall.

A good formula to remember: 1 inch of rain on a 1000 sq ft roof yields 623 gallons of water. Calculate the yield of your roof by multiplying the square footage of your roof by 623 and divide by 1000.

For those of you in a city, collecting rainwater on the roof to water your household plants is a great option. I send you forth with the confidence that you will be able to convince your landlord that it is a practical and cost-effective option. It also means that his/her and your water bill is cheaper monthly. The rainwater collection will encourage rooftop gardens, and as a result cool the roof and make cooling your building easier and cheaper. The benefits are never-ending.

For those of you out in the country who might have a few more plants and acres of maintained land, this is a very cost effective option for you as well. It takes lots of water to keep those plants and that lawn healthy. Why not collect it for free and feed them the clean, untreated juice they love and deserve! You might even have the option to install multiple rain barrels on a few corners of your house or estate.

Whether you like it or not (but I think you will like it) collecting rainwater doesn’t just save you money and provide you with good plant drinking water. Rainwater collection eases our demand and impact on the municipal water grid, meanwhile keeping the environment cleaner. Rain commonly travels across our land picking up harmful chemicals from fertilizers and pesticides. After traveling across the land it dissipates to the water table and erodes our rivers, and lakes with water unfit for drinking and often times swimming. Agricultural herbicides are found in 99% of all urban streams sampled. When you think about the fact that 2.1 billion gallons of water move from the Great Lakes to the Gulf of Mexico daily, we are reminded of how much water is constantly traveling through our watershed. Since pollution from city streets, suburban lawns, and factories are of the largest of contributors to water pollution, let’s use our tools to reduce the odds of that not-so-green option.

Additionally, rainwater commonly travels down the street collecting harmful petrol-chemicals from oil and gasoline. When and if this water travels through our sewer system to the water treatment plant, it has to be treated with chlorine, lime, or calcium to restore safety. Not only do we not want to drink these solvents, but these dissolved salts, sediments, and chemicals are not palatable to our lawns and plants. When we intercept water during rainfall, we reduce the impact of all the aforementioned steps. Brilliant!

There is a little family of asexual plants commonly known as duckweed, and otherwise known in the botanical world as lemnaceae. These smallest flowering plants are lean, lime-green, clean, eating machines. Lemna is the most common of this family, and has quite a profound impact for its size. Each plant has one paper thin leaf the size of the tip of an eraser. They thrive in freshwater lakes, streams, and ponds high in nitrogen, ammonias, and phosphorus. As they feed on these “excess nutrients” the tiny plants help remediate the water on which they live atop.

Though these lime-green plants are tiny, there is no need to call them fragile. They can grow in full sunshine or dense shade, and they endure a challenging range of ph levels. They hibernate during the cold months at the bottom of their watershed and, come May, the plant “springs” up and gets to work cleaning its ecosystem. This tiny plant has been known to cover bodies the size of football fields in just a couple months. It goes unsaid that these tiny soldiers are friend and not foe when it comes to water remediation.

When artist and engineer Viet Ngo established a company back in 1983 called Lemna International that applauds and utilizes the capabilities of these mini soldiers, we weren’t surprised. Ngo, a first-generation Vietnamese immigrant, and his colleagues got a little fame when they designed a carefully engineered art installation in 1990 on Devils Lake, ND. Funded by the EPA, they designed and implemented the beautiful 50 acre, 9 channel, intestine-like system that extracted all detrimental phosphorus, nitrogen, and algae from the wetland before the water reached a bay of Devils Lake. This $50 million project encouraged the group of designers, artists, and engineers to combine the profoundly simple yet complex water remediation technology with other environmental infrastructure problems to clean up the earth. Over 25 years later, the company is managing its success with innovation, consciousness, and integrity.

Lemna International designs environmentally responsible and economical wastewater treatment technologies that naturally clean our polluted waterways. They design for everything form dams to freshwater remediation to drinking water treatment plants, pipelines, and distribution systems. Based in Minneapolis, MN the company has designed and implemented over 300 projects in 16 countries.

The company does not stop at only providing us with clean water. They make sure our water stays clean by removing any harmful waste and either safely putting it in landfills built to international standards, or incinerating it to generate electricity and heat in facilities equipped with air pollution control systems. Their impressive profile of clients ranges from industrial food manufacturers and tire plants to hospitals. They additionally serve a number of cities worldwide.

As the company gained momentum with their patented water remediation technology, they have branched out into additional sectors of environmental infrastructure including transportation, alternative energy, and general infrastructure. Like the lean, lime-green, clean, machines that duckweed are, Lemna International is actively seeking to fix any environmental problem a private or public client might have with an ingenious and unique solution!

Recent headlines have been telling us about a class of chemical detergents or surfactants (nonylphenol ethoxylates, NPE’s) found in many industrial and household cleaners that have been reported to cause male fish to develop female characteristics. This hormone instability is commonly due to foreign “hormone disruptors”. The hormone instability occurs when a foreign chemical is introduced to the body and imitates our natural hormones. The toxins bind to the same sites in our body where natural hormones bind, therein blocking the site from our natural hormones.

This chemical disruption is not going to facilitate spawning! Do we dare to question what these chemicals are doing to us? A World Wildlife Foundation Briefing on the chemical states that "NPEs has been shown to mimic the action of the female hormone oestrogen, and it is a potential factor in the increasing incidence of reproductive organ disorders and decreasing sperm counts in men."

The Sierra Club has asked the Environmental Protection Agency to ban this compound in areas where wastewater treatment plants are not equipped to extract it. The greater question is, how is it getting into our waterways and estuaries and effecting wildlife? In this I respond with: water is the most abundant molecule on earth, it is also referred to as the universal solvent. Combine these two facts and we get a lot of water that is not clean.

The World Wildlife Foundation report on how NPEs are reaching our water environment:

• 37% NPEs via the sewer system
• 46% via sludge spreading on agricultural land

Chemical pollutants that cause hazardous runoff come from lawn fertilizers, industrial pesticides, household cleaners, leaky tailpipes, industrial waste, store byproduct (such as a drycleaners), this runoff is not good. If you take this information inside with the newspaper, you realize that the pollution in your home is due to off gassing from materials you bring in that were treated with chemicals (everything from carpet to magazines) and cleaning products.

So here is the simple solution: just read your labels. We can’t eradicate chemical pollution immediately, but we can start acting consciously by purchasing safe and simple cleaning products, fertilizers, and food. A rule to shop by, if you can’t read it, don’t eat it (remember that 46% of this stuff is spread on our industrial farms-buy organic), and if you can’t pronounce it, don’t spray it on your counter (when you wash your hands this water goes down the drain to the treatment plant…).

One of the scariest commercials on TV right now is for a cleaning company whose products contain compounds we should not come in oral contact with. It shows the mom cleaning the countertop with this product then her child eating cookies from a box that just tipped over onto the same countertop. The mom is relieved because she just cleaned the counter from harmful bacteria, but simultaneously she could have put harmful chemicals on it that are equally as disrupting to her child’s health.

One sixth of the world’s population does not have access to safe drinking water. Most water born problems are due to bacteria that cause them to contract harmful diseases. We don’t need to add chemical hormone disruption to this list. In purchasing safe cleaning products, food, and supporting safe practices we are creating a safer living environment, reducing pollution in our waterways, enabling biodiversity, promoting natural reproduction, and helping to provide safer drinking water for the entire world.
