Popular emblem for hard hats in the USA. The original quote is attributed to Sailor Jack, a famous tattoo artist.

The title for this post is a popular emblem on US hard-hats and was the motto of a famous, WWII era tattoo artist. It’s also at the heart of a divide between the skilled trade unions and the labor movement. Skilled laborers expect to be paid more than unskilled, while the labor movement tends to push for uniform pay, with distinctions based only on seniority or courses taken. Managers and customers prefer skilled work to not, and usually don’t mind paying the skilled worker more. It’s understand that, if the skilled workers are not rewarded, they’ll go elsewhere or quit. Management too tends to understand that the skilled laborer is effectively a manager, often more responsible for success than the manager himself/herself. In this environment, a skilled trade union is an advantage as they tend to keep out the incompetent, the addict, and the gold-brick, if only to raise the stature of the rest. They can also help by taking some burden of complaints. In the late 1800s, it was not uncommon for an owner to push for a trade union, like the Knights of Labor, or the AFL, but usually just for skilled trades for the reasons above.

An unskilled labor union, like the CIO is a different animal. The unskilled laborer would like the salary and respect of the skilled laborer without having to develop the hard-to-replace skills. Management objects to this, as do the skilled workers. A major problem with unions, as best I can tell, is a socialist bent that combines the skilled and unskilled worker to the disadvantage of the skilled trades.

Not all unionists harbor fondness for welfare or socialism.

Also popular. Few workers harbor a fondness for welfare or socialism. Mostly they want to keep their earnings.

Labor union management generally prefer a high minimum wage — and often favor high taxes too as a way of curing societal ills. This causes friction, both in wage-negotiation and in political party support. Skilled workers tend to want to be paid more than unskilled, and generally want to keep the majority of their earnings. As a result, skilled laborers tend to vote Republican. Unskilled workers tend to vote for Democrats. Generally, there are more unskilled workers than skilled, and the union management tends to favor Democrats. Many union leaders have gone further — to international socialism. They push for high welfare payments with no work requirement, and for aid the foreign socialist poor. The hard-hats themselves tend to be less than pleased with these socialist pushes.

During the hippie-60’s and 70’s the union split turned violent. It was not uncommon for unionized police and construction workers to hurl insults and bricks on the anti-war leftists and non-working students and welfare farmers. Teamster boss Jimmy Hoffa, supported Nixon, Vietnam, and the idea that his truckers should keep their high wages at the expense of unskilled. Rival teamster boss, Frank Fitzsimmons pushed for socialist unity with the non-working of the world, a split that broke the union and cost Hoffa his life in 1975. Eventually the split became moot. The war ended, US factories closed and jobs moved overseas, and even the unskilled labor and poor lost.

Skilled workers are, essentially managers, and like to be treated that way.

Skilled workers are, essentially managers, and like to be treated that way.

The Americans with Disability Act is another part of the union split. The act was designed to protect the sick, pregnant and older worker, but has come to protect the lazy, nasty, and slipshod, as well as the drug addict and thief. Any worker who’s censored for these unfortunate behaviors can claim a disability. If the claim is upheld the law requires that the company provide for them. The legal status of the union demands that the union support the worker in his or her claim of disability. In this, the union becomes obligated to the worker, and not to the employer, customer, or craft — something else that skilled workers tend to object to. Skilled workers do not like having their neighbors show them high-priced, badly made products from their assembly line. Citing the ADA doesn’t help, nor does it help to know that their union dues support Democrats, welfare, and legislation that takes money from the pocket of any one who takes pride in good work. We’ll have to hope this split in the union pans out better than in 1860.

Robert Buxbaum, June 5, 2016. I’m running for water commissioner. I’d like to see my skilled sewer workers rewarded for their work and skill. Currently experienced workers get only $18/hour and that’s too little for their expertise. If they took off, they’d be irreplaceable, and the city would likely fall to typhus or the plague.

The chemistry of sewage treatment

6 Replies

The first thing to know about sewage is that it’s mostly water and only about 250 ppm solids. That is, if you boiled down a pot of sewage, only about 1/40 of 1% of it would remain as solids at the bottom of the pot. There would be some dried poop, some bits of lint and soap, the remains of potato peelings… Mostly, the sewage is water, and mostly it would have boiled away. The second thing to know, is that the solids, the bio-solids, are a lot like soil but better: more valuable, brown gold if used right. While our county mostly burns and landfills the solids remnant of our treated sewage, the wiser choice would be to convert it to fertilizer. Here is a comparison between the composition of soil and bio-solids.

The composition of soil and the composition of bio-solid waste. biosolids are like soil, just better.

The composition of soil and the composition of bio-solid waste. biosolids are like soil, just better.

Most of Oakland’s sewage goes to Detroit where they mostly dry and burn it, and land fill the rest. These processes are expensive and engineering- problematic. It takes a lot of energy to dry these solids to the point where they burn (they’re like really wet wood), and even then they don’t burn nicely. As shown above, the biosolids contain lots of sulfur and that makes combustion smelly. They also contain nitrate, and that makes combustion dangerous. It’s sort of like burning natural gun powder.

The preferred solution is partial combustion (oxidation) at room temperature by bacteria followed by conversion to fertilizer. In Detroit we do this first stage of treatment, the slow partial combustion by bacteria. Consider glucose, a typical carbohydrate,

-HCOH- + O2 –> CO2 + H2O.    ∆G°= -114.6 kcal/mol.

The value of ∆G°, is relevant as a determinate of whether the reaction will proceed. A negative value of ∆G°, as above, indicates that the reaction can progress substantially to completion at standard conditions of 25°C and 1 atm pressure. In a sewage plant, many different carbohydrates are treated by many different bacteria (amoebae, paramnesia, and lactobacilli), and the temperature is slightly cooler than room, about 10-15°C, but this value of ∆G° suggests that near total biological oxidation is possible.

The Detroit plant, like most others, do this biological oxidation treatment using either large stirred tanks, of million gallon volume or so, or in flow reactors with a large fraction of cellular-material returning as recycle. Recycle is needed also in the stirred tank process because of the low solid content. The reaction is approximately first order in oxygen, carbohydrate, and bacteria. Thus a 50% cell recycle more or less doubles the speed of the reaction. Air is typically bubbled through the reactor to provide the oxygen, but in Detroit, pure oxygen is used. About half the organic carbon is oxidized and the remainder is sent to a settling pond. The decant (top) water is sent for “polishing” and dumped in the river, while the goop (the bottom) is currently dried for burning or carted off for landfill. The Holly, MI sewage plant uses a heterogeneous reactors for the oxidation: a trickle bed followed by a rotating disk contractor. These have higher bio-content and thus lower area demands and separation costs, but there is a somewhat higher capital cost.

A major component of bio-solids is nitrogen. Much of this in enters the form of urea, NH2-CO-NH2. In an oxidizing environment, bacteria turns the urea and other nitrogen compounds into nitrate. Consider the reaction the presence of washing soda, Na2CO3. The urea is turned into nitrate, a product suitable for gun powder manufacture. The value of ∆G° is negative, and the reaction is highly favorable.

NH2-CO-NH2 + Na2CO3 + 4 O2 –> 2 Na(NO3) + 2 CO2 + 2 H2O.     ∆G° = -177.5 kcal/mol

The mixture of nitrates and dry bio-solids is highly flammable, and there was recently a fire in the Detroit biosolids dryer. If we wished to make fertilizer, we’d probably want to replace the drier with a further stage of bio-treatment. In Wisconsin, and on a smaller scale in Oakland MI, biosolids are treated by higher temperature (thermophilic) bacteria in the absence of air, that is anaerobically. Anaerobic digestion produces hydrogen and methane, and produces highly useful forms of organic carbon.

2 (-HCOH-) –> CO2 + CH4        ∆G° = -33.7 Kcal/mol

3 (-HCOH-) + H2O –> -CH2COOH + CO2 +  2 1/2 H2        ∆G° = -21.9 kcal/mol

In a well-designed plant, the methane is recovered to provide heat to the plant, and sometimes to generate power. In Wisconsin, enough methane is produced to cook the fertilizer to sterilization. The product is called “Milorganite” as much of it comes from Milwaukee and much of the nitrate is bound to organics.

Egg-shaped, anaerobic biosolid digestors.

Egg-shaped, anaerobic biosolid digestors, Singapore.

The hydrogen could be recovered too, but typically reacts further within the anaerobic digester. Typically it will reduce the iron oxide in the biosolids from the brown, ferric form, Fe2O3, to black FeO.  In a reducing atmosphere,

Fe2O3 + H2 –> 2 FeO + H2O.

Fe2O3 is the reason leaves turn brown in the fall and is the reason that most poop is brown. FeO is the reason that composted soil is typically black. You’ll notice that swamps are filled with black goo, that’s because of a lack of oxygen at the bottom. Sulphate and phosphorous can be bound to ferrous iron and this is good for fertilizer. Generally you want the reduction reactions to go no further.

When allowed to continue, the hydrogen produced by anaerobic digestion begins to reduce sulfate to H2S.

NaSO4 + 4.5 H2 –>  NaOH + 3H2O + H2S.

I’m running for Oakland county, MI water commissioner, and one of my aims is to stop wasting our biosolids. Oakland produces nearly 1000,000 pounds of dry biosolids per day. This is either a blessing or a curse depending on how we use it.

Another issue, Oakland county dumps unpasteurized, smelly black goo into Lake St. Clair every other week, whenever it rains more than one inch. I’d like to stop this by separating the storm and “sanitary” sewage. There is a capital cost, but it can save money because we’d no longer have to pay to treat our rainwater at the Detroit sewage plant. To clean the storm runoff, I’d use mini wetlands and weir dams to increase residence time and provide oxygen. Done right, it would look beautiful and would avoid the flash floods. It should also bring natural fish back to the Clinton River.

Weird flow calculation

Here is a nice flow problem, suitable for those planning to take the professional engineers test. The problem concerns weir dams. These are dams with a notch in them, somethings rectangular, as below, but in this case a V-shaped notch. Weir dams with either sort of notch can be used to prevent flooding and improve the water, but they also provide a way to measure the flow of water during a flood. That’s the point of the problem below.

A series of weir dams on Blackman Stream, Maine. These are thick, rectangular weirs.

A series of weir dams with rectangular weirs in Maine.

You’ve got a classic V weir on a dam, but it is not a knife-edge weir, nor is it rectangular or compound as in the picture at right. Instead it is nearly 90°, not very tall, and both the dam and weir have rounded leads. Because the weir is of non-standard shape, thick and rounded, you can not use the flow equation found in standard tables or on the internet. Instead, you decide to use a bucket and stopwatch to determine that the flow during a relatively dry period. You measure 0.8 gal/sec when the water height is 3″ in the weir. During the rain-storm some days later, you measure that there are 12″ of water in the weir. The flow is too great for you to measure with a bucket and stopwatch, but you still want to know what the flow is. Give a good estimate of the flow based on the information you have.

As a hint, notice that the flow in the V weir is self-similar. That is, though you may not know what the pattern of flow will be, you can expect it will be stretched the same for all heights.

As to why anyone would use this type of weir: they are easier to build and maintain than the research-standard, knife edge; they look nicer, and they are sturdier. Here’s my essay in praise of the use of dams. How dams on drains and rivers could help oxygenate the water, and to help increase the retention time to provide for natural bio-remediation.

If you’ve missed the previous problem, here it is: If you have a U-shaped drain or river-bed, and you use a small dam or weir to double the water height, what is the effect on water speed and average retention time. Work it out yourself, or go here to see my solution.

Robert Buxbaum. May 20-Sept 20, 2016. I’m running for drain commissioner. send me your answers to this problem, or money for my campaign, and win a campaign button. Currently, as best I can tell, there are no calibrated weirs or other flow meters on any of the rivers in the county, or on any of the sewers. We need to know because every engineering decision is based on the flow. Another thought: I’d like to separate our combined sewers and daylight some of our hidden drains.

Weir dams to slow the flow and save our lakes

3 Replies

As part of explaining why I want to add weir dams to the Red Run drain, and some other of our Oakland county drains, I posed the following math/ engineering problem: if a weir dam is used to double the depth of water in a drain, show that this increases the residence time by a factor of 2.8 and reduces the flow speed by 1/2.8. Here is my solution.

A series of weir dams on Blackman Stream, Maine. Mine would be about as tall, but somewhat further apart.

A series of weir dams on Blackman Stream, Maine. Mine would be about as tall, but wider and further apart. The dams provide oxygenation and hold back sludge.

Let’s assume the shape of the bottom of the drain is a parabola, e.g. y = x2 , and that the dams are spaced far enough apart that their volume is small compared to the volume of water. We now use integral calculus to calculate how the volume of water per mile, V is affected by water height:  V =2XY- ∫ y dx = 2XY- 2/3 X3 =  4/3 Y√Y. Here, capital Y is the height of water in the drain, and capital X is the horizontal distance of the water edge from the drain centerline. For a parabolic-bottomed drain, if you double the height Y, you increase the volume of water per mile by 2√2. That’s 2.83, or about 2.8 once you assume some volume to the dams.

To find how this affects residence time and velocity, note that the dam does not affect the volumetric flow rate, Q (gallons per hour). If we measure V in gallons per mile of drain, we find that the residence time per mile of drain (hours) is V/Q and that the speed (miles per hour) is Q/V. Increasing V by 2.8 increases the residence time by 2.8 and decreases the speed to 1/2.8 of its former value.

Why is this important? Decreasing the flow speed by even a little decreases the soil erosion by a lot. The hydrodynamic lift pressure on rocks or soil is proportional to flow speed-squared. Also, the more residence time and the more oxygen in the water, the more bio-remediation takes place in the drain. The dams slow the flow and promote oxygenation by the splashing over the weirs. Cells, bugs and fish do the rest; e.g. -HCOH- + O2 –> CO2 + H2O. Without oxygen, the fish die of suffocation, and this is a problem we’re already seeing in Lake St. Clair. Adding a dam saves the fish and turns the run into a living waterway instead of a smelly sewer. Of course, more is needed to take care of really major flood-rains. If all we provide is a weir, the water will rise far over the top, and the run will erode no better (or worse) than it did before. To reduce the speed during those major flood events, I would like to add a low bicycle path and some flood-zone picnic areas: just what you’d see on Michigan State’s campus, by the river.

A run runs through it

The word ‘run’ appears to be a Michigan dialect for small river. Perhaps Michigan’s most famous run is the Willow run, where the airport is. Currently, almost all of our runs are unrecognizable, they are either trapped in pipes underground, or so dredged out and poisoned that they are more properly called sewers. If I’m elected Oakland county water resources commissioner (drain commissioner) I’d like to free some of these runs, and detoxify them.

These branches of the red run flow beneath the surface of Royal Oak with the main section beneath Vinsetta Blvd.

These branches of the red run flow beneath the surface of Royal Oak with the main section beneath Vinsetta Blvd.

Consider this historical map of Royal Oak. It shows two  river branches, currently under ground. Back in the day, these were known as the north and south branch of the Red run. The south branch is fed by the Washington creek and the small run, now under ground, with the main branch of the run crossing Woodward ave at Catalpa st. These runs only appear above ground in Warren, MI, miles away, as a polluted sewer. But in Royal Oak they should still be clean. If they were partially freed. That is if the channel were exposed to air again to provide small wetlands along the original path — along Vinsetta Blvd, for example. Vinsetta Blvd. already has concrete bridges to show where the run originally ran. The small wetlands would provide habitat for birds and butterflies, and would provide storm relief and some bioremediation as well. After a heavy rain, most of the water would be absorbed into the ground, while the existing pipes carry away the rest.

Thinking the unthinkable

Do you know how you go about thinking the unthinkable?

 

With an ithberg, of course.

 

Robert Buxbaum. April 12, 2016. I thought it was time for another “dad joke.” Besides, the Titanic sank on April 14th. I spend a fair about of time thinking the unthinkable. On a vaguely similar note:

After Boris died, everyone gathered at his funeral.

The minister started to speak: “He was a model husband, a decent man, a terrific father..”

The widow then makes a motion for her son to come to her.

“What is it mother?” he whispers.

“Dear, go check the casket, I think we’re at the wrong funeral…”

Narcissism, a horrible disease except in presidents.

Perhaps the worst sort of employee is a narcissist. A narcissist is in love with an image of himself that he sees, and that he has created. Though his behavior does not match the image — it can not –the narcissist can not, or will not accept the damage he’s caused by insubordination and undercutting. The typical narcissist is always right, and is confident of being right, even when seriously wrong. He can take some (little) advice because he sees himself as humble, but he will not take blame, and thus does not change. He can be charming in his love of you and your ideas. Still, you’ll notice his complete disdain for others and of ideas that (to you) look equally brilliant. And once he accepts your first idea as brilliant, he’s unlikely to change to accept your second, or modified version.

The Great Gatsby created an image of himself, and strove to live it. "He looked at you like the moon and the stars shone out of your eyes."

The Great Gatsby created an image of himself, and strove to live it. “He looked at you like the moon and the stars shone out of your eyes.”

The narcissist friend or boss is somewhat better. He creates a positive mental image of those around him, usually seeing them as kind, holy, or smart people. The Great Gatsby was a classic example of this. It’s nice to be in his presence, “seen as you’d wish to be seen, as if the moon and the stars shone in your eyes”. It’s an image the narcissist does his best maintain, both of you and of him, even if it kills you and him together. This is still a damaging, false image, but it has a tremendous up-side or two in a friend or boss. It’s nice to work with someone who sees you as God’s gift even if you know it’s false. Besides that, the narcissist usually has some general plan of action or knows how to get one (e.g. hire the best, consult the iChing, build a wall). The plan might not be great, but it’s usually better than having no-plan or waiting to consult the consultants at every turn. And unlike most folks, the narcissist knows he must stick to the plan or he looks like a loser. It also helps that he or she, by force of charisma, has the ability to make others stick to the plan. In times of trouble or confusion, that’s usually far better than hopeless paralysis. Also good is that narcissists tend to collect solid followers — a plus when leading a big organization where decisions are important. The leader can not hope to manage all the details of a big organization, and needs to be able to rely on loyal minions to follow general his orders and get the details right.

There are few bigger organizations than government. Government leadership has seen an uncommon concentration of narcissists, and these have done rather well, considering. In the US and elsewhere the best (and worst) leaders have been narcissists, mostly. Napoleon, FDR, Stalin, Churchill, Christ, Mohammed, Hitler, Bill Clinton, Gandhi, and Genghis Kahn; all narcissists as best I can tell. They all saw themselves as great, behaved accordingly, and got people to follow. They made grand plans and carried them out by convincing others to go along: the others providing the necessary blood, sweat, tears, and death. Their approach may appall when seen in quiet times, but it’s absolutely necessary in troubled times when the normal alternatives are confusion and despair. Jimmy Carter, a more-normal type, folded in times of trouble; he dithered in the face of the Ayatollah and of Idi Amin. Twice he started Iranian rescue operations, then called them off — in both cases at the worst possible moments. People died, friends lost hope. Carter was a normal person in a situation that required a narcissist. Meanwhile, the Ayatollah and Idi Amin did as narcissist do, for better or worse.

It’s been pointed out that Donald Trump is a narcissist (he is, congratulations). I strongly suspect that’s true of Cruz, and Sanders too. Trump’s narcissism is unusually blatant because his vision of himself is unusually brash. Cruz and Sanders, have quieter visions of themselves mixing feigned humility with their firm resolve. I don’t see these visions as better, just more normal-looking. Brash visions can be a negative, of course, both in a US president, and in a corporate president, but to have no vision is worse. Apple computer company seems to have no vision now that Steve Jobs is dead, and it’s floundering. Jeb! Bush, similarly seemed to have had no firm vision, and he ended his run as a washed-up flotsam. As for HRC, I don’t know. Fortunately, the US government has the power to rein in any (I think) narcissist, via the constitution’s balance of power. Congress and the supreme court, if they choose to use it, have the power to stop any excess of a narcissist president. The narcissist will fight, but will eventually will bend to them; the one thing the narcissist does not wish is to see himself as, is as a loser, and they have the power to portray him that way. The US will survive whoever gets elected.

Robert Buxbaum, April 10, 2016. I’m not a psychologist and might be dead wrong here, but how I see things at the moment is that Trump’s narcissism is manageable and perhaps advantageous. Besides, I’ve argued in favor of tariffs for some time, so we have some policy agreement. For April Fools day, last year, I described the duel of a famous narcissist president, Andrew Jackson, with his lawyer.

The map below shows, in white, all the countries that England has not invaded.

The white spots on this map are the countries that England has not invaded.

The white spots on this map are the countries that England has not invaded.

England now controls virtually none of these countries. In most of these, English is the national language, or the language of business, and defeating the British is hailed as the central national experience. Still, many have opted to become part of the British Commonwealth, a loose organization of ex-British states. Generally this requires agreeing to the rule of the Queen, despite having nominally free states. Entering Canada, for example, one finds a picture of Elisabeth II, Queen of Canada, And there are royal colleges where inventions belong to her. The same with Australia and New Zealand. The question to ask, then, the question despots have asked, is how did the English manage it –or perhaps, how can I extend my despotism the same way. Part of the answer, it seems to me, is that England used tall, silly hats: Busbys and Bearskins.

The Queen of Canada reviews her troops. She's wearing a Busby; he's in a bearskin.

The Queen of Canada reviews her troops. She’s wearing a Busby; he’s in a bearskin.

The Bearskin hat is perhaps the silliest hat in worldwide military use, and certainly the largest. The bearskin is made of the complete skin of a black or a brown (grisly) bear dyed black, The skin is shaped over a wicker frame to stand 16″ tall (a black bear skin is used for enlisted men, and a grisly bear for officers). It is heavy, quite fuzzy, and completely non-aerodynamic and protects the head not at all. As best American military experts have found, it only makes the person wearing it a better target for being shot. And yet, Britons have striven to be given the honor of wearing this thing. There is also a slightly shorter, slightly fuzzier version of the Bearskin worn by officers. It’s called a Busby, and it’s made from beaver skin. Even in this day of social correctness, skins are found for this use, and “harvested”, mostly in Canada.

The front-line British soldiers in the American Revolution wore these hats when they marched in ranks to attack the colonials at Lexington and Concord, and again at Bunker Hill, and again, in the war of 1812 at New Orleans. It made them slow, impressive, and dead. Because of their weight, these hats are often worn with a leather collar to help support them. The collar makes it hard for soldiers to look down, a plus for soldiers on parade, but a minus when walking over uneven ground, e.g. when attacking Bunker Hill. You’d think the British would have given up on these weird hats long ago, but the British won in many conflicts and have come to dominate many countries. They seem to credit the hat, I’m beginning to think it deserves more attention than it’s gotten.

The hat they wore through the war of 1812, through the Crimean war and the Boer war; in the heat of the Indian revolts, in Africa, and to this day for show makes British soldiers look taller, and more elegant. It makes them stand straighter than most, and gives guards an other-worldly appearance. American soldiers uniformly reminisced how hard it was to shoot someone who marched so elegantly. The Queen likes them, and she, after all is nothing if not elegant. Perhaps the unworldly elegance of the bearskin give soldiers the courage to invade countries and die in the name of a sovereign who reigns by Devine right as expressed through the sword Excalibur ‘of pure Semite’, whatever that is. It’s a story that not one adult Britain believes, yet they die for (why?) Perhaps it’s the honor of mass craziness. Perhaps, because they see simple folks are impressed by soldiers wearing the tall funny hats (I guess thats why some US marching bands use them). And then again, it might be pure luck, superstition, and stupidity. The method of science would be to ask if other countries or team bands do better while wearing the silly hats. I suspect not, but it deserves statistical analysis.

Follow the feces; how to stop the poisoning

4 Replies

In Oakland county, we regularly poison our basements and our lake St Clair beaches with feces — and potentially our water supply too. We have a combined storm and sanitary sewer system that mixes feces-laden sanitary sewage with rainwater, and our pipes are too old and small to handle the amount of storm water from our larger rains. A group called “Save Lake St. Clair” is up in arms but the current commissioner claims the fault is not his. It’s global warming, he says, and the rains are bigger now. Maybe, or maybe the fault is wealth: more and more of the county is covered by asphalt, so less rain water can soak in the ground. Whatever the cause, the Commissioner should deal with it (I’m running for water commissioner, BTW). As the chart of toxic outfalls shows, we’ve had regular toxic sewage discharges into the Red Run basically every other week, with no exceptional rainfalls: only 0.9″ to 1.42″.

Toxic outfalls into lake St Clair, Feb 20 to Mar 20, 2016. There were also two outfalls into the Rouge in this period. These are too many to claim they are once in hundred-year events.

Toxic outfalls into lake St Clair, Feb 20 to Mar 20, 2016. There were also two outfalls into the Rouge in this period. These are too many to claim they are once in hundred-year events.

Because we have a combined system, the liquid level rises in our sewers whenever it rains. When the level is above the level of a basement floor drain, mixed sewage comes up into the basement. A mix of storm water comes up mixed with poop and anything else you and your neighbors flush down. Mixed sewage can come up even if the sewers were separate, but far less often. Currently most of the dry outfall from our old, combined sewers is sent to Detroit’s Waste Water Treatment plant near Zug Island. When there is a heavy rain, the pipe to Zug is overwhelmed. We avoid flooding your basement every other week by diverting as much as we can of the mixed storm water and septic sewage to lake St. Clair. This is poop, barely treated, and the fishermen and environmentalists hate it.

The beaches along Lake St Clair are closed every other week: whenever the pipes to Detroit start getting overwhelmed, whenever there is about 1″ or rain. Worse yet, the sewage is enters the lake just upstream of the water intake on Belle Isle, see map below. Overflow sewage follows the red lines entering the Clinton River through the GW Kuhn — Red Run Drain or through the North Branch off the River. From there it flows out into Lake St. Clair near Selfridge ANG, generally hugging the Michigan shore of the lake, following the light blue line to poison the metro beaches. it enters the water intake for the majority of Oakland County at the Belle Island water intakes, lower left.

Follow the feces to see why our beeches are polluted. It's just plain incompetence.

The storm water plus septic sewage mix is not dumped raw into lake St. Clair, but it’s nearly raw. The only treatment is to be spritzed with bleach in the Red Run Drain. The result is mats of black gunk with floating turds, toilet paper and tampons. This water is filtered before we drink it, and it’s sprayed with more chlorine, but that’s not OK. We can do much better than this. We don’t have to regularly dump poop into the river just upstream of our water intake. I favor a two-prong solution.

The first, quick solution is to have better pumps to send the sewage to Detroit. This is surprisingly expensive since we still have to treat the rain water. Also it doesn’t take care of the biggest rains; there is a limit to what our pipes will handle, but it stops some basement flooding, and it avoids some poisoning of our beaches and drinking water.

This is our combined sewer system showing a tunnel cistern (yuk) and the outflow into the Red Run. We can do better

A combined sewer system showing a tunnel cistern. Outflow goes into the Red Run. We can do better.

A second, longer term solution is to disentangle the septic from the storm sewers. My approach would be to do this in small steps, beginning by diverting some storm runoff into small wetlands or French drain retention. Separating the sewers this way is cheaper and more environmentally sound than trying to treat the mixed flow in Detroit, and the wetlands and drains would provide pleasant park spaces, but the project will take decades to complete. If done right, this would save quite a lot over sending so much liquid to Detroit, and it’s the real solution to worries about your floor drains back-flowing toxic sludge into your basement.

The incumbent, I fear, has little clue about drainage or bio-treatment. His solution is to build a $40MM tunnel cistern along Middlebelt road. This cistern only holds 3 MM gallons, less than 1/100 of the volume needed for even a moderate rain. Besides, at $13/gallon of storage, it is very costly solution compared to my preference — a French drain (costs about 25¢/gallon of storage). The incumbents cistern has closed off traffic for months between 12 and 13 mile, and is expected to continue for a year, until January, 2017. It doesn’t provide any bio-cleaning, unlike a French drain, and the cistern leaks. Currently groundwater is leaking in. This has caused the lowering of the water table and the closure of private wells. If the leak isn’t fixed , the cistern will leak septic sewage into the groundwater, potentially infecting people for miles around with typhus, cholera, and all sorts of 3rd world plagues.

There is also an explosion hazard to the incumbent’s approach. A tunnel cistern like this blew up near my undergraduate college sending manhole covers flying. This version has much bigger manhole covers: 15′ cement, not 2′ steel. If someone pours gasoline down the drain during a rainstorm and if a match went in later, the result could be deadly. The people building these projects are the same ones who fund the incumbent’s campaign, and I suspect they influenced him for this mis-chosen approach. They are the folks I fear he goes to for engineering advice. If you’d like to see a change for the better. Elect me, Elect an engineer.

Stories of Jewish charity

Before Passover this year, an individual went to the rabbi of our town for a private meeting to tell him about the problems facing various people. He said, there was one particularly pathetic case where a family could lose their house. They had borrowed $5000 from a particularly nasty lender who would throw them out in the cold if they didn’t pay up soon.

Our rabbi was touched, and said he would do what he could to raise the sum. He would even contribute $100 of his own. As the fellow left, he had just one question, ‘How do you come to know this is going on? Are you a relative, or particularly close friend?” “No,” said the guest, “I’m the lender.”

 

Another story of Jewish charity: a neighbor of ours takes incredible care of her husband, She spends quite a lot, regularly to get his nails done professionally. She says it’s worth it to know that his coffin is secure.

Finally, I must admit that I’d wanted to marry my ex-wife, who I had divorced previously — sort of an act of kindness. But she would have none of it. My ex said I was only marrying her for my money.
