1. Septic waste needs additonal processing. Dedicated filtration installations remain.
Factually correct, and totally irrelevant. Yes, septic waste is processed. So is sewer sewage. The difference is that septic waste is cheaper, faster and less labor intensive to process. Yes, filters need to be replaced. That happens when the pumping service is done, typically every 3 to 5 years. The pumping process takes about 30-45 minutes, and filter replacement is a trivial 5 minute thing to do. There are youtube videos of this.
2. Sewers are needed to prevent floods, by carrying away rainwater. No sewers, no gutters.
You have no clue what you're talking about.
http://en.wikipedia.org/wiki/Street_gutterA street gutter is a depression running parallel to a road designed to collect rainwater flowing along the street and divert it into a storm drain."http://en.wikipedia.org/wiki/Storm_drain"A storm drain...is designed to drain excess rain and ground water from paved streets, parking lots, sidewalks, and roofs.""Storm drains are separate and distinct from sanitary sewer systems."There's no relationship between these two systems. Combined systems have existed in the past, but they've not been in common use since the 1930s. Gutters and storm drains are simple pathways, generally paved with concrete to direct the flower of water. A sewer system connects houses to purification plants via pumping stations. To say that there can be no gutters to direct water without sewer purification and pumping systems is completely ridiculous.
3. Septic tanks require drainage fields.
-Large (Impossible in cites and some surburban areas)
-Effects on water table if used en masse. A septic tank can last so long by filtering out all the water.This water is slightly polluted. (phosphates and other things. Comparable with overuse of fertilizer).
-If the water table is too high (after rains, or because everyone is using them), the system backfires and the tank floods.
Yes, it's not a good solution for
some areas. I'm tired of linking this but here it is again:
Perfect Solution fallacy.
Yes, there are some places where septic systems don't work very well. I've acknowledged this several times. It's completely stupid to reject a solution because there are specific cases where it doesn't work. Use it where it works, don't use it where it doesn't. The goal here is to increase efficiency and reduce workload. Septic systems have a lower work requirement than sewer systems. In environments where it's suitable, use the more efficient system.
4. Everyone has to use biodegradable products or the internal filtration process
fails and polluted water is dumped into the drainage field.
...what?
After reading that several times I can only assume that what you're trying to point out is that septic systems are not designed to handle non-biodegradable materials. Yes, if you dump cigarette butts and tampons and things into the system, that will create problems. The solution is...
don't do that. You may as well object to people having cars with combustion engines because if you don't change the oil and replace the filter occasionally, they tend to break. It's a stupid argument.
Incidentally, guess what? You're
not supposed to flush those things down a toilet even if you're on a sewer system either, because they clog that up too. You just don't
see it and somebody else from the city has to deal with it, paid by you indirectly via tax money.
But, since you bring it up, the repair issue is actually a point in
favor of septic systems. While they can break if you mistreat them, they're
cheaper to fix when they do break.
Average septic repair cost is $285, and absolute worst case when a septic system breaks, you dig it up and put a new one in for a couple thousand dollars. If you simply treat the systems well and maintain them properly you won't have these problems, and if you do, that's as bad as it gets.
Whereas when a sewer system breaks, that can run
$20,000 even for just a break under one house, and
BILLIONS of dollars in event of major breakage.
$12 Billion sewer repairPopulation of Miami-Dade is 408,75012 billion / 408,750 is a cost of $29,357 per person. That
can't happen with a septic system. You could completely rip up from the ground, throw away and replace 408,750 septic systems and it wouldn't cost that much.
Again, I've said this multiple times, it bewilders me that anyone needs it spelled out...a septic tank is basically a couple-thousand-gallon metal drum with some filters on it that you install on a house, and give a simple, cheap maintenance to every couple years. A sewer system requires interconnecting subterranean pipe systems beneath
hundreds of square miles of a town or city, plus pumping stations, plus purification centers, all of which must be staffed and maintained every single day.
Common sense should tell you that a septic system would be less labor intensive, and the numbers I've given, linked and sourced again and again demonstrate that septic systems are cheaper.
