The main answer is logistical. Building a network of pipes to bring water to houses is a major effort, and most places where that's been done found it extremely expensive. Providing a second set of pipes to bring salt water to houses would probably cost about the same. Except that cities go to considerable lengths to put their water reservoirs above the city ...

Catalina Island does use salt water for toilets. It's a small community, however, and they seem to be shifting towards freshwater due to corrosion issues inherent to salt water utilization. From Catalina Island & Drinking Water: Saltwater used for toilet-flushing and fire suppression purposes is simply filtered as it is not intended to be potable. ...

If you kept the coils clean, filtered the air blowing over them, and captured the water immediately before it had a chance to pool and potentially grow bacteria, then yes, the water is very clean and pure. Probably as pure as distilled water (if not for all of the dust and other contaminants that blow through it). Legionnaires Disease is an example of a ...

Part of it may be the stage in composting. In moving the pile, you had to aerate it well which would speed things up. Remember that much plant material is cellulose and lignan. Cellulose has the same molar forumula as sugar -- it's really just thousands of sugar molecules chained together, so in essence it's CHO. The net reaction is 4 CHO + 3 O2 => 4 ...

I found this page that contains a link to a MSc dissertation on the Pulser pump. The dissertation describes 2 experiments with Pulser pumps and shows that the efficiency is around 1% at best (page 56) and that the author found ...inflow, pumping height and the number of riser pipes to be critical variables. It was also discovered that there is potential for ...

Regardless of where you live, one or more of the following most likely applies: Damaging ecosystems by removing scarce water. If you live in an arid place, the water you waste would have been used somewhere else. Note this may also apply in areas that don't meet the definition of arid, but are experiencing drought conditions. Damaging ecosystems by ...

Life cycle assessment has been done on this! This report is by InSinkErator, so they obviously have some commercial interest. Here's the summary, which (to me) seems sound: http://www.insinkerator.com/en-us/Documents/Disposer/ISE-Life-Cycle-Summary.pdf I will search out the original study report, which will define more of the assumptions they're making and ...

I know that tea tree oil is poisonous when ingested, just like you said, but it is also toxic for animals upon contact. It must go into the blood stream by penetrating the skin. Because it exists in the composition of insect-repellents and plant fungicids, I presume that it is toxic to insects too. There are discussions at the European Union parliament as ...

I was faced with a similar question a couple of years ago. The best solution I could come up with was to feed the grey water into an area occupied by plants that consumed 'large' quantities of water and continuously dropped leaf litter. The leaf litter would layer on top of the particulates in the grey water and provide protection to the micro-organisms ...

It might even be more environmentally friendly to dispense with using flush toilets altogether by switching to using negative pressure toilets. Vacuum toilets are used on planes and also help to remove the unwanted odours as well as prevent the toilet plume aerosol caused by flush toilets. Vacuum toilets are available commercially for domestic use and use ...

Your parents taught you not to "waste water" because they paid the water bills. Thus the negative connotations associated with "wasting water" are purely (or at least overwhelmingly) economic. It does not logically follow that "wa$ting water" is bad for the environment. Your question "why is it bad..." is thus loaded. You've assumed something that ...

If you don't add additional detergent to your wash (nor do additional wash loads because you believe your cloths come out without being cleaned as well) to compensate for any effects (real, imagined, or otherwise) of the added oils then you cannot be wasting detergent. You are using the same amount of detergent whether you add the essential oils or not. ...

Check the TRM for recent, state-specific data Illinois (and probably other states) now requires energy efficiency programs to estimate the energy impact of water supply and discharge -- in Illinois, the value is 0.68 watt-hours per liter (footnote 122 of the Illinois Technical Reference manual). The TRM of the state you're interested in would probably ...

Another strategy with human & animal waste involved is growing algae from the effluent to purify the water, recycling it then cheap and easy, uniits are insulated, LEDs via fiber optics climate controlled for 24x7 growing. This supplies biodiesel to the village, enough for heat & to replace diesel use, vehicles to snowmobiles. Nobody makes the ...

One possible solution would be to construct mulch pits around trees, etc. and then discharge the greywater directly into the bottom of the mulch pits. The mulch pits will help decompose any grease/particles and the phosphates, etc. should help feed the trees. Select soaps that are low in sodium. Sodium can be toxic to plants in high enough concentrations. ...

Navy/Marine ships usually have two systems to handle water, in separate tanks: CHT: Collection, Holding and Transfer tanks (more detail on the standards by the SBIR here) MSD: Marine Sanitation Device tanks Ships use salt water from the fire main for flushing, and to clean out the CHT (shit, which is used when sewage can't be dumped, or to process before ...

I had a painful full-body hives reaction to Tea Tree Oil when applied topically. I suppose this was an allergic reaction or some kind of hyper-sensativity. Also, there has been some research indicating tea tree oil is an endocrine disruptor, even when applied topically, which means it has unpredictable effects on the human hormone system.
