Septic tank problems

Finally got the septic guy out to check the backup at the farm house. Good news- the root clog was removed so I can use the bathroom.
Bad news- the side walls of the tank are caving in. Tank was built out of concrete blocks on site in 1966 so I can't complain. However he is already booked up on installations until the first of next year.

Concrete has a way of deteriorating from the gas buildup in tanks which turns to ACID as it reacts , Hydrogen Sulfide turns to Sulphuric Acid  and corrodes concrete . 
Now if blocks are only corroded on one side - still have part left to hold out the dirt    

Here they say every 3 years for pumping / or yearly if a garbage disposal is used .
Now thing also is a Outlet Filter on last tank (they now require 2 tank system and a 3rd tank if pump system .
Other new requirements coming into play in Nitrogen reducing devices to reduce water of dissolved nitrates. 
 Odd as a few years back attended a Septic Workshop for the Trade Organization I belonged to and they had a fellow from University in Washington State who had did tests on water quality in soils of different systems and found at 2 to 3 ft out from a normal drain field - the old systems of trench and rock had as good treatment as so called modern systems using pretreatment and sand or peat filter systems or aeration systems  which were be called the modern alternative .
 other big thing here now is Mound Systems where a artificial sand barrier is built under drain field - and pressure distribution is used to treat full mound area in dosing by controlling pump cycling.   

One of the things I did run into on failing systems was people who were on many medications as the latent effects of many drugs killed the bacteria in the tanks to point things did not break down in tanks .
 The Sludge and Scum layers in tank are the big concern , not the effluent itself as that is treated by drain field absorption of water .
