The Lecteasan is a good gadget, though the proliferation of no discharge
zones into the open sea increasingly threatens it. When it is operating
properly the sewage is treated to almost sterile levels and causes no harm
whatever to the environment.
That's not entirely true.
The Lectra-San kills all the bacteria. It does not reduce or break down
the material effluent, which contains nutrients and changes the local
ecological balance.
Is this "damage" to the environment? It is, if you liked what was
growing there before.
It is still a whole lot better than raw sewage. And I suspect that in sea water
where there is a daily tide range of eight feet or more and only
seasonal boating, eutrification is not a major problem, nowhere near the
amount caused by runoff from coastal lands.
Do you suppose that's where our oysters went? By the way, have you ever seen
the effluent from an oyster farm? Eeeyuuu!
