When did the US Economy start to tank?

I do much prefer traditional tank and leach field designs and try to stay away from places with the aerobic (s#$t sprinkler) design which is more costly to keep maintained and much more costly to fix or put in place. 

Of course she just thought I was a heartless shark (obviously she wasn't there when I had a heart and didn't bid against the other family) so she just brushed me off. 

The local economy can tank so completely and far that local rents must be cut because the local economy demands that the rent be cut.

They know that if they let the tank get completely empty, they may be responsible for a service call.

There may be a small leak from your tank to bowl connections. 

For example, replacing a water tank on a $30k house will cost more or less the same as replacing a water tank on a $300k house, though their rent prices will be dramatically different.

You can invest in the entire market, but if the entire market tanks, I still believe my portfolio to be superior to the index because I only try to buy what I believe to be the best companies.

Fish can cause water damage if the tank leaks or breaks.
