Sustainable Living – One Step At A Time: Water Conservation - Part II

In light of the current drought in California, I have revisited this issue since the last time I wrote about it.

Water conservation must be one of the easiest things we can do. According to an article posted by the Sierra Club, the three biggest sources of water consumption are: 
  1. The toilet (26.7 %)
  2. The clothes washer (21.7%)
  3. The shower (16.8%)
The article mentions that there is huge variability of course, and it is not clear what is used as a base line here (a 1.6 gal/flush toilet or something with higher consumption, what kind of clothes washer, and what showerhead etc.).

At any rate, changing out a toilet can cost anywhere between $200-$500. Changing out a decent clothes washer can run anywhere from $700-$2000 for high-end clothes washers. A showerhead, however, will at most cost about $80 for which you will get a luxury showerhead while having the potential of cutting the water usage more than half!

So they are affordable compared to replacing a toilet or washing machine, but in addition to water savings, they have two other ways in which they pay for themselves:

1.) Cutting down on hot water usage cuts down on natural gas usage or electricity depending on how you heat your water.
2.) Some places charge for the amount of sewage water produced which you will also be able to cut down.

And this brings me to today's topic:

Showerheads

In the search for ever more efficient showerheads compared to the current standard (2.2 gpm), I have over the past 6 years tried out the Niagara showerheads. The first showerhead I bought was the Earth 1.5 gpm showerhead from Niagara. It's a solid choice saving you 32% of hot water each time you shower compared to a 2.2 gpm showerhead. Wanting to push the boundaries, I also tried the Earth 1.25 gpm showerhead from Niagara. The latter was really hard to find back then, and it turns out that there is a reason for it.  In the words of a roommate:"That showerhead felt like a little sprinkler on half on." I wouldn't put it quite like that but, the performance felt borderline anemic for me as well. I have also had the pleasure of trying out the 1.75 gpm and 2.2 gpm version of this showerhead. Not too surprising, this is the order I would rate those showerheads:

Earth 1.25 gpm (borderline underperforming < <Earth 1.5 gpm (feels like a full shower) < Earth 1.75 gpm (feels luxurious) ~ Earth 2.2 gpm (not much of a difference compared to the 1.75 gpm version).

So why am I mentioning this? Up until recently, I thought that then 1.25 gpm consumption in showerheads was the furthest you could push it -  that is until I tried a couple of showerheads from Bricor. Bricor has a number of showerheads, I have tested the following:

- Eco-Fit: This shower head uses 1.25 gpm instead of 2.5 gpm - a savings of ~50%.
- Eco-Miser: This is a variation of the Eco-Fit using only 1.0 gpm which saves ~60%.
- A modded B125 Supermax: I tried the version that only uses 1.0 gpm.

I am happy to report that all showerheads are workable. Both the Eco-Miser and modded B125 Supermax perform slightly better than the Niagara 1.5 gpm showerhead. One big difference is that the showerhead from Niagara sprinkles water out in a circular pattern leaving a big cold hole in between that makes you feel longing for more water. All showerheads from Bricor cover that central part. The Supermax even allows for adjustment of the water stream which is really satisfying. As for the Eco-Fit, it is amazing that a 1.25 gpm showerhead can feel like a strong 2.5 gpm showerhead.

If I had to give out recommendations, I would say that the 1.0 gpm showerheads will be satisfactory for anyone who feels good using an otherwise 1.5 gpm showerhead and wants to maximize water savings. I would recommend the Eco-Fit without any reservations to anyone who wants to have a strong stream and save water. The price for these showerheads is really affordable. So for just $30-40 you can cut your shower water consumption by %50-60 which overall will save about 8% of water consumption in the entire house. That's efficient!

Focus on Algae - Part I: Bioremediation

After spending the last few blog posts on different aspects of dissimilatory bacteria, I want to switch the focus to a different class of organisms I have been interested in for a long time now. These are the algae. Algae comprise a large diversity of "sea weeds" and an even larger variety of single-celled organisms that mostly are capable of doing photosynthesis. They include the ordinary sea-weed, and make up a portion of the green slime found around the edges and the bottom of a pond. More exotic types of algae can live symbiotically - that is together with another organism in a mutually beneficial way. Lichens are an example of symbiotic relationship between algae and fungi. More information about the evolution and lineage of algae can be found in this wiki article.

Typically, these organisms are either not mentioned at all or only in conjunction with toxic algal blooms. But lately, algae, of course, have been in the news recently because of the promi…

Sustainable Living: One man's trash...

Since Earth Week is starting tomorrow, I wanted share with you some concrete ways of how individuals like you and me can make an impact on a wider scale. I then also wanted to use this example to challenge everyone to think creatively about the larger context.

So you know how the saying goes: "One man's trash is another one's treasure." Today, I want to talk to you about garbage. Plastic garbage specifically. Plastic is quite a wondrous material. Made from oil by man with just a few additives can turn this polymer into so many different sorts of plastics with so many different properties from thin and flimsy plastic bags, to the carpet on which I am standing, to this plastic bottle from which I am drinking.
