Work: Post Collapse

What sort of work will there be, post collapse?  Translation: as the industrialized nations enter a period of small to large collapses brought on by unmanageable debt and environmental/climate chaos, many systems are no longer going to function properly, if at all.  Scarcity of lots of common goods and services will be the order of the day.  Scavenging will be a requirement for survival.  Producing food, clothing, shelter, protection and some modest medical care will be important.

What are some "jobs" in this post collapse world?

• Banking - Not the old style 9 - 3 traditional banker.  People who can maintain small local banks, protect deposits, lend locally and know the local community quite well.  Flexible people who can deal with alternative currencies, maybe even locally developed ones.
• Sanitation workers - People who can install and service septic tanks, outhouses, ecologically designed in-house toilets.  People who can integrate waste systems into compost piles.  Other skills: water purification (as municipal systems no longer provide safe potable water).  Can you turn compost in fertilizer?  Because once the natural gas becomes unavailable, no more synthetic fertilizer.  Bonus: Can you make natural pesticides?
• Fix-it shop keepers.  People who can repair things, like furniture, cookware, bicycles, fireplaces, roofs and windows.
• Defense - State and county provided law enforcement services are simply going to break down in many areas.  Police cars may not have gasoline available.  Police services and the national guard may not be supportable.  Full or part time local self defense will be a requirement for communities that wish to protect what they care.  Can you make and maintain simple firearms?  What about ammo?
• Lots of part time stuff, like: fire department staff, road, trail maintenance (forget about state and federal road support).  
• Home builders and maintainers: People who can get hold of local mostly materials and use local tools to build and maintain dwellings.
• People who can make and work with glass and insulation and other vital building supplies.  Can you repair a roof, or keep the cold out?  Great!
• Traders - Can you build up relationships with distant suppliers of spices, fabrics, raw materials like cotton, iron, food, building supplies, glass, medicine, medical instruments, small electrical components like light bulbs, lamps, wire, batteries and sockets?  Can you oversee their transport from where they are made/grown to where you will sell them?  Then you'll be that all important trader and middleman.  
• Food growers: Farmers who can grow for their own family and 2 - 8 other families, depending on land and resources.  People who can grow part of what they consume.  Remember: only natural fertilizers, i.e., night soil, yours and the animals.  
• Blacksmiths and small machine shop operators.  People who make lots of different items which are no longer available, especially if they were made overseas.  And horseshoes: Yes, horses will be making a comeback in many areas.  Can you make a plow and a hitch?  Shovels, pliers, hammers, door locks?  What about a fishing rod and hooks?  What about a washing tin and a bath tub?  A wood burning stove?  A water pump? 
• Medical care: Physicians and assistants who can treat people in ways that don't rely on a globalized medical instrument and pharmaceutical system.  Can you make/fix/supply eye glasses?   What about a microscope?  [Forget about contact lenses - far too complex].
• Traditional pharmacists.  People who can make pills and potions from materials available locally and regionally.  Bonus points if you can make anesthesia, antiseptics, antibiotics, aspirin and birth control pills.  What about condoms, band aids?  Can you maintain an X-Ray machine, if electricity is available?
• Refrigeration techs, maybe even ice suppliers.  People who can make low energy consuming systems/boxes that preserve food.  Can you make and maintain an ice house, and deliver the ice?
• Insurance - An idea that's been around for centuries.  Can you develop new ideas about how to create simple forms of insurance that can be funded and supported locally?
• Vets, animal techs and people who can buy/sell/breed horses, chickens, sheep, goats.
• Recyclers - People who can collect old junk - detritus of industrial civilizations - and find ways to use it again, more sustainably.
• Small scale electricity providers and maintainers.  Not clear whether photovoltaics and modern wind generators will survive a collapse of industrial society.  Will it be possible to make PV cells and small windmills and micro-hydropower on a small local scale?  If you can figure this out, you might be able to get rich, whatever rich means in a post-industrial future.  Can you make light bulbs?
• Stoves, ovens and fireplace maintenance installation and repair.  Forget about electric heat.  There will probably be natural gas until there's a major industrial collapse.  Then people freeze if their dwellings aren't able to get heat from sustainable sources.
• Morticians, gravediggers and cemetery maintainers.  The earth's human population is going to go through a major bottleneck in the 21st century.  If the human race survives, it will almost certainly be at a level far below 1 billion people.  Thus: a lot of dying, probably from diseases, starvation and violence.  Safe disposal of the bodies will be a requirement if the survivors are not to get new diseases from failing to dispose of the dead.  You'll need to work with the sanitation workers to pickup and safely dispose of contaminated corpses.
• Can you make soap and disinfectants?  
• Clothing makers: Can you work with fabric?  Can you turn raw wool into a sweater?  Can you make new clothes from old ones?  
• Fuel supplier: Can you provide firewood and/or other sources of sustainable cooking and heating fuels?
• Ecologists.  People who can develop deep understandings of the natural environment and help promote sustainable human societies that also support a rich diversity of wildlife.
• People who can make/service wagons. carts, bikes, small transports power by horses.
• There will be new religions, or new versions of old religions.  Can you help develop the theology and mythology that will be needed by a civilization in "decline and fall" mode?  Can you lead a funeral service?  Conduct a wedding service?
• Shopkeeper - For small shops like hardware, clothing, simple furniture, groceries, building supplies, mostly from local and regional suppliers.
• Butcher, baker, candlestick maker: Old time craftsmen and women.  We'll almost certainly be restricted to diets with less meat, especially beef, but given human history, it's almost certain that some level of meat consumption will continue.  And we'll all want bread and cakes.  Candles?  We can't count on 24x7x365 grids and backup systems may not be available or charged, but we'll still need lights after dark.
• Soap maker, vendor of cleaning supplies.  
• Electricians and plumbers: There will almost certainly be les electricity available, and much of what is will be locally generated.  Can you maintain these systems and the systems of small businesses and home owners?  Can you work with low voltage DC systems?  Can you install a simple windmill and keep it running?  What about a solar hot water system?  Can you clean out the pipes?  Can you make, recycle and repair batteries?
• Arborist: Can you take care of trees and orchards?  Deal with pests?  Can you manage and sustain a tiny section of forest and supply neighbors with firewood?
• Grape or grain grower: yes, we'll still be drinking wine and beer, and stronger stuff.
• Watch and clockmakers - We'll still want to know what time it is
• Weather forecaster - Can you read the clouds and collaborate with other forecasters to develop accurate predictions?  Without and satellite images?  Local radar may be all you get.
• Experimental scientist - Like Ben Franklin and Galileo.  Can you form hypotheses and test them without federal grants and expensive equipment?  Can you identify diseases based on cell cultures? Can you find a "day job" and do the science "part time"?
• Jack of all trades - People who possess many skills and can undertake new projects and manage existing ones will be valuable.
• Miners - Can you mine metal from mines?  Can you scavenge from junk yards and other detritus piles of industrial civilization?
• Brick and concrete makers: Can you make these from local materials?  What about mortar?
• Newspaper and book publisher: Local papers will be making a comeback.  Can you manage a daily or weekly schedule?  Can you take care of a printing press and do the distribution?  Do you have a source for ink?  Can you recycle the paper?
• Paper makers - Can you make paper?  The newspaper people will need you.
• Toy maker - I hope we live in a world where children still have the "luxury" of playing with toys.
• Beekeeper - Who doesn't like honey?
• Map makers - In a world where energy is expensive, we aren't going to be able to keep making sophisticated GPS satellites or launching them into orbit.  People are going to have to rely on maps for more distant travel.
• Innkeeper - Can you renovate an old hotel, motel or multi-bedroom house cook and clean it and welcome travelers?
• Teacher - Up through high school.  Math, reading, ecology, basic science, vocational skills
• Analysts - This is sort of my little joke that there will be opportunities for people who try to make some sense of what's going on, what the future may hold, and to explain it to fellow citizens.

Do you have more ideas?

Here are some jobs that will, post-collapse, be disappearing.  Pretty much any profession that appeared after the middle of the 20th century:

• Software programmer, computer manager, designer.  Solid state electronics requires a globalized economy and very complex, high energy manufacturing.  This isn't going to be sustainable.
• Stock broker.  While there will probably still be stock companies, the degree that country's economic systems will be financialized will be greatly reduced.  
• Ski resort employees.  Probably not much snow and certainly very little discretionary income to travel there and to pay for the electricity to run the lifts, which will be impossible to maintain.
• Car dealer.  Maybe some used cars will still be used and traded, depending on price and availability of petrol.  Learn to raise and sell horses.
• Big Box store owner, manager, employee: These kinds of businesses depend on a fully globalized supply chain and cheap products from overseas.  That's not sustainable.  Learn to be shopkeepers and sell local and regional goods.
• Airline pilot - Commercial aviation will largely be gone by mid 21st century.  
• Web designer.  The Internet will shrink a lot and where it remains, will be much more of a local/regional resource.  People will be too busy earning their daily bread to surf.
• Long haul truck drivers.  To the extent that diesel truck are still in use, they'll mostly be for local and regional deliveries.  Forget about refrigerated ones - too much fuel required.
• Meeting planners, travel agents, cruise ship staff, airline personnel, rental car agency employee.  All of these will be going away as travel become too expensive except for the very wealthy and the very daring.
• Politician, fund raiser - It's impossible to know exactly what kind of post-collapse, post-carbon future we'll end up with.  Probably many different varieties, depending on region size, population size and what is produced.  But only the very largest regions - of which there will probably be few - can support traditional politicians.
• University professor, college student.  Yes, universities have been around for about nine hundred years.  But modern universities are very much the creation of the cheap energy, fossil fuel powered industrial state.  So if you're very bright and very lucky, you may find an new Oxford, probably sponsored by a religious organization, where you can work... If you can find the students.  It's going to be very difficult for any but the children of the wealthiest people to attend any kind of university.  But increasingly, it will be less and less necessary: the kind of jobs that today's universities are preparing people for are disappearing already.

Don't see what you want to do?  What were people doing in 1859 or before, when the first US oil well was drilled?  Maybe you could do something that was common in the mid 19th century or before.

Police and Fire

It's summer in Tahoe now which means there are regular threats of forest fires.  There's also a lot more police work due to the much larger numbers of tourists and weekend visitors.

Modern police work and modern firefighting - the kinds that quickly dispatch qualified, well-trained first responders to dangerous situations - could not happen without fire engines, police cars, ambulances, occasionally helicopters and reconnaissance aircraft, and up to date wide area weather forecasts, not to mention drivable roads.  And every one of these things depends on the ready availability of affordable gasoline, diesel and airplane fuel.

As I write this in 2013, there's plenty of liquid fossil fuels available, mostly at below $4/gallon.  And even in these difficult economic times, our local governments are still able to pay for reasonable numbers of police and fire fighters, plus their training and health care, not to mention upkeep and replacements for all the necessary gear: police cars, emergency equipment, fire defense and suppression tools, an underground network of water pipes and hydrants.  Add to that periodic burns to clear out underbrush and we have a pretty good system of responding to fires, law enforcement emergencies and other first responder situations.

But as we look forward a decade, and perhaps sooner, a few warning signs become visible: We're running out of the easy to find, easy to extract oil that we depend upon for reliable affordable liquid fuels.  We're also starting to "run out" of the long term weather pattern we've grown used to at the Lake: cold winters with lots of snow that last well into summer in the higher elevations.  Instead we're starting to get the occasional bigger storm that is followed by sunny skies and warmer temperatures which melt some of the snow that just fell.  Spring snow melt occurs earlier too.  We're left with hotter, drier summers which can increase the dangers of wildfires.

Fortunately, right now conditions related to fighting fires, law enforcement and emergency response seem acceptable and affordable to the Tahoe region.  We'd be making a mistake if we planned on these conditions continuing for more than a decade or so.  Within that time, it's almost certain that the prices Americans pay for liquid fuels will increase substantially.  We'll also be facing a hotter, drier climate with increased risks of fires.  Whether Lake levels will stay where they are or decrease is too difficult to predict.

It's not too soon to start thinking about how we, as Tahoe dwellers, can plan on getting by with lower levels of police and fire fighter support.  Our lives may one day depend on it.

Road and Pipe Maintenance vs. 400 PPM

Summer season is approaching and Memorial Day is around the corner.  In the Tahoe area, as in many other northern regions of the United States, this means we're enter the the season of road maintenance and water/sewer pipe upkeep.

Anyone who has traveled to or around the Lake in the Summer has almost certainly seen some highway or local street maintenance.  Some of that may be actual road repairs; some may be repairs or replacements of underground water or sewage pipes.  Without well maintained roads and reliable water and sewer pipes, life in the Tahoe area would be almost impossible.  At least it would be impossible for the great majority of "modern" people who now live here, as well as any visitors.

All of these repairs require powerful gasoline or diesel powered equipment.  Road repairs sometimes apply new asphalt or concrete, materials that require fossil fuels to manufacture and transport.

So, what's the problem with fixing our roads and keeping our piping system working?  There's no problem except that these activities require substantial amounts of fossil fuels, and unless we're prepared  instead to employ lots of strong men and women with shovels and have the jobs take far longer, there's no alternative right now.   So what's the problem with that; why can't we just keep repairing roads and pipes the way we've been doing it for the last 50 years?

The short answer is that the concentration of CO2 in the earth's atmosphere just recently crossed 400 PPM, a level not seen for at least 4 million years.  If we continue burning fossil fuels at current rates of consumption (and countries like China and India are increasing their consumption), we'll cross 450 PPM by 2037.  That's the absolute maximum upper limit that climate scientists tell us we can go to still keep the earth's average temperature at not more than 2 degrees C (3.8 degrees F) above historical averages.  2 degrees C isn't safe: It's merely a value that scientists think the human population can tolerate.  There will still be major climate changes: fiercer storms, a rising ocean, melting glaciers, decrease in arable lands, less snowfall, more  drought in drier areas.

So what's that got to do with road and pipe maintenance in the Tahoe area?  We can't be the only ones causing global warming, can we?  Of course we aren't.  Burning fossil fuels, especially coal, is bad wherever it happens.  But unless the United States and China begin quickly reducing their consumption of oil and coal, we'll stay on the track we are on.  And this track leads to blowing by 450 PPM and into the realm of climate disaster... into the realm of making earth a planet that is much less able to support human life.

But we can't stop maintaining our roads and pipes, can we?   We don't really have to do this, do we?  Right now there is little choice.  If we want the Tahoe area to be inhabitable by modern humans, then we need roads and water and sewer infrastructure.  Can the maintenance be done without using fossil fuels?  Right now, it appears not.  The available heavy equipment that does the digging and related tasks is all powered by gasoline or diesel fuel.  There's no alternative, though it may be possible to develop equipment that uses fuel cells or other technologies that are what's called "carbon neutral" - meaning they don't add new CO2 to the atmosphere.

We have a long way to go before we can maintain our local infrastructure in ways that do not destroy the earth's climate.  And we don't have much time to find out how.  So it's vital that we support research and development into projects that can provide affordable, sustainable energy supplies to our homes, business, transportation and life support systems.... and that means roads and water/sewer pipes.

If we can't provide clean water and functional sewage systems, and low pollution ways for people to live and travel in the Tahoe area, then most humans will simply pack up and leave.  And if we do nothing, the earth's climate will make it increasingly difficult to live anywhere, including at the Lake.

The Death of Snow Plows

It's now May in the Tahoe area.  Rains are falling and temperatures are in the 40s - 50s.  So why am I thinking about snow plows?  Because for at least six months of the year, snowfall is a frequent presence, and without plows to clear the roads, motorized travel can be impossible.  Anything over a few inches of fresh snow can make driving, even for those with four wheel drive vehicles, too difficult to attempt.  Without reliable snow plows, we can rule out delivery of food, medical supplies, gasoline, hardware store items.  In less than a week, store shelves would be empty of items critical to survival.

Do we really have anything to worry about?  Aren't we guaranteed that country and state governments will keep the roads clear... forever?   No such guarantee exists.  Global oil production has been essentially flat since 2005.

Why does that matter in the Tahoe area, or anywhere else, for that matter?  It matters because it indicates that we have reached a peak, a somewhat flat peak for now, but that at some point in the relatively near future (probably within a decade or two), global oil production will start its irreversible trend downward.  When that happens, oil prices, and thus gasoline and diesel prices, will rise.  Well, so what, can't the country just pay more for gasoline to keep the snow plows running?  Yes, of course it can, but only in the short term.  As the years go by and oil prices continue to rise, the use of the personal motor car wil decline and less people will travel to Tahoe as a vacation getaway.  That means less highway taxes for governments and less of a motivation to plow every road currently attended to.

At some point, governments will be forced to ask: What are the most critical roads, because those are the only one we can afford to plow?   That leads to even less people being able to spend some of their winter months in the Tahoe area... which puts less cars on the roads, and provides the governments with even less of an incentive to use snow plows.  Sooner or later - unless residents of snowy areas like Tahoe find ways to pay more money for snow plowing - the road conditions could become undrivable after snow storms.  [The other wild card, besides oil prices, is global climate change.  We'll probably see less total snow, and lighter amounts, but still quite enough to seriously clog the roads for the likely future.]

I'm not predicting that "the death of snow plows" will happen any time soon.  But as energy prices rise, and the overall economy contracts, it becomes more and more difficult for governments to provide services.  Priorities will have to be reestablished.  Can we count on snow plows clearing the Tahoe roads indefinitely?   Look at the struggles to repair public schools, provide medical care for those without insurance, care for the elderly, fight foreign wars, keep Social Security, Medicare and Medicaid alive.  It's not hard to see that in an era of contracting economies, many regional government officials may not see snow plows as a top priority.

So what can we do?  It's time to talk about what are the vital streets, how to keep them clear of winter snow as revenues decline, and what backup plans we will need when these streets cannot always be plowed.  If we don't address this issue, then many parts of the Lake Tahoe community become uninhabitable during winter months.... just as was the case a century and a half ago.  Is this what we want?

Transportation

Everyone who lives anywhere near the Lake is at an elevation of at least 6225 feet.  That means, among other things, that our daily temperatures and road conditions limit bicycling to perhaps six months of the year (May - October).  For the rest of the year, we either walk (or trudge, if there's snow) to and from our destinations.  Unless we need travel more than about a mile.  Then we have to rely on either personal cars, public transit or private conveyance (taxis, limos).  All of these run on gasoline, except for most of the buses, which use natural gas.  All of the snow plows, which make road travel possible in the winter, use gasoline.  Every tourist or part-time resident gets here by car, bus, train or airplane, or some combination of these.

While there are some hybrid vehicles and a few all electrics on the road, virtually all of Tahoe's transportation needs are met primarily by petroleum and secondarily be natural gas.  To state the obvious: Neither of these occurs naturally in the Tahoe area.  We have to import all the gasoline, diesel, natural gas (and for that matter, electricity) that we use for transportation.  Making this situation more difficult is that there is very limited public transportation in the Tahoe area.  For example: Try traveling from the SF Bay area by train to Incline Village, or South Lake Tahoe.  This requires either hiring a taxi or taking one or more long bus rides.  Any major increase in oil prices will have a very detrimental effect of Tahoe transportation: both because life becomes more expensive where our visitors life, and because it becomes more expensive and time consuming to get here and travel about while visiting.

There are no simple answers to dealing with the Tahoe area's strong reliance on imported fossil fuels.  In the winter, life would be very difficult if the snow plows and school buses could not easily be fueled.  Many residents would face extreme hardship if they could not easily afford or find gasoline.  Buying food and getting to medical appointments would be very challenging.  People who work in the Tahoe community, but live in Reno or Carson City, would have trouble getting to their jobs.

But because there is no "immediate emergency", it's very difficult to lobby for improved public transportation.  Yet that's what will be needed if, or rather when, the price of gasoline and diesel means that increasing numbers of residents will no longer be able to afford private motor cars.  If we want to keep the Tahoe area as a year round natural resort, retreat and just destination for tourists and vacationers, we need to think much harder about how we can develop and support robust, reliable and affordable systems of transportation.  There is no magic bullet - this is a hard problem.

Renewable vs. Sustainable Energy

In order to establish sane long-term policies about how we, as Tahoe residents, and every other citizen produce, transport and use energy we need to understand the difference between renewable and sustainable energy.  These terms are frequently used interchangeably as if they meant the same thing.  Let's learn why...

Renewable energy is an energy source that exists in forms that are continually, if sporadically, created by nature.  Common examples would include wind, solar, tides.  These supplies are created whenever the wind blows, sun shines or tides come in and go out.  Another well-known renewable energy source is water power, which has been used widely since at least the Middle Ages.  Rivers power water wheels or have water collected behind dams which when released powers electric turbines.  Another energy source, geothermal (thermal energy from beneath the earth's surface) is often consider renewable because it purportedly exists in large "nearly inexhaustible" quantities.

All of these energy sources are considered relatively diffuse - widely distributed around the earth's surface, but concentrated more in some regions than others.   Fossil fuels, on the other hand, are very concentrated forms of energy, which is the main reason humans have found oil, natural gas and coal so valuable.  When first discovered, these fossil fuels seemed inexhaustible.  It wasn't until the mid 1950s that solid evidence indicted this was not the case.  The idea that oil, natural gas, and coal are finite resources and have a rate of extraction that peaks and then declines remains controversial,  One of these versions of the theory, "peak oil," remains politically charged today even though peak oil theory is more of an objective observation than a theory yet to be proved.

What's the difference between renewable and sustainable energy?   A sustainable energy source, which should more accurately be called a sustainable energy system, is capable of indefinitely supplying useful energy to human society while also generating enough energy to cover all the costs of manufacturing, transporting, installing, maintaining and eventually replacing the system.   Using this definition, it's highly unlikely that any existing solar or wind system today would be considered sustainable.  Renewable energy?  Yes.  But are these systems sustainable?  Not unless they produce a good deal more energy than they now yield.

So, if renewable energy systems are not really sustainable, at least today, should we still keep developing them?  Yes, we should because even though they are not currently sustainable, their efficiencies continue to improve and their prices are dropping.  They still need a fossil fuel subsidy (in the form of manufacture, transport, and maintenance) and are therefore quite a ways from being truly sustainable.  But some of solar approaches, especially passive solar (really, just good architectural design) and solar hot water heating show the most potential for becoming sustainable soon.

Can solar (or wind) electric systems ever become sustainable?  Can they ever produce enough electricity to pay for their own manufacture, transport, installation, maintenance and eventual replacement?  It's too soon to know with any certainty, but we have to make this a goal, even if we're not that close today.... unless we're prepared to abandon electricity!  Therefore, the best approach right now is to adopt as many energy conservation techniques as we can afford in order to use as little electricity as we can somewhat comfortably survive on.  Add to that: whenever possible, use electricity that is generated from renewable resources: solar, wind, water power.

In the Tahoe area we have a very good amount of solar energy, but very limited ways that we can turn that into electricity without damaging the natural environment.  The wind energy we have fluctuates a great during over the course of a year, and during each day.  As with solar power, we cannot easily install wind power systems, to capture this wind energy without impacting the natural beauty of the area. So, do we still have any options to use renewable energy, and hope that some day it becomes sustainable?  In fact we do.  They involve purchasing electricity generated by wind or solar sources, at sites that are on the national electric grid, so that we can, in effect, go renewable without installing systems at the Lake.

What else can we do?  We can boost the amount of insulation where we live: more in the walls, more in the ceiling, and as good a set of windows as we can afford.  This cuts down on the heat energy we have to pay for and makes our houses and apartments more affordable in the long term.  And if you're lucky enough to be designing your own new house, go passive!

Water: Supplies and Wastes

"Water, water, every where ... Nor any drop to drink"  - Samuel Taylor Coleridge (The Rime of the Ancient Mariner).   Tahoe residents are very fortunate to have such a wonderful resource as the Lake, which serves as the critical focus for our communities.  The lake is a source of recreation, small amounts of food (fish), and of course drinking water.

But we can't safely drink the lake's water unless it's been purified or otherwise treated to remove dangerous bacteria and any other harmful agents that may have been detected.  Purifying water on a scale to serve the Tahoe communities requires that the towns (water districts) use various chemical additives, including anti-bacterial agents.  None of these chemicals are native to the Tahoe area.  Water purification and delivery to regional homes and businesses requires electricity to run pumps and purifying equipment.  In addition, purified water must be stored in large tanks, generally at higher elevations, so it may flow downhill to where it is used.

The short story is thus: we have plenty of water, but it takes energy and chemicals from sources outside the Tahoe region in order to pump and prepare the water so it's safe for us to drink.  Without safe drinking water coming out of the tap, residents would be required to purchase small purification systems or camping units in order to have access to safe water.  In addition: people would need to be careful not to get shower or bath water into their mouths or eyes.  Tourists would be quite reluctant to visit a region without reliably safe drinking water.

What happens to water when we are done with it?  We excrete it as urine in toilets and send the dish water, cooking water and washing water down the drains.  To the best of my knowledge, all of this waste water is piped away from Tahoe communities to larger urban areas in Nevada or California.  No waste water is recycled, ending up back in the lake.  Piping water away requires expensive periodic maintenance of the sewage systems and installation of components that are transported from distant locations.  It also takes energy to manage the wastes once they end up at a sewage processing facility.

It is considered unlikely that any Tahoe community would seek to build a local wastewater recycling facility "at the Lake".  Even if they did, it's very questionable whether a regional authority like TRPA, or other local communities would support the action.

If the Tahoe region is to become more sustainable in the long run, it will need to make an assessment of how much energy, chemicals and maintenance expense are currently spent on water purification and waste processing.  We would need to decide to what extent these services (safe drinking water, safe waste disposal) can be supported.  Assuming they are high priorities, we need to make sure that our communities generate the economic revenue to support current water and waste processing.  If such support becomes difficult to impossible in the future, we need to be ready to discuss alternative approaches to purifying water and safely recycling human wastes.
