1)If a septic tank sewage treatment system is properly installed, taken care of and the proper information TO DO THIS is distirbuted, to a small community of residents, do you concur that people are intelligent enough to properly maintain and supervise thier own treatment system.
2)Is it enviromentally known that when proper care is taken, that a system can be used efficiently, whereby there is no need to touch said system at all, for at least 15 – 30 years.
1.)Yes if the correct info is give to the owner about the type of system that they have and how to operate and maintain it. 2.)No, it is not know. If you mean that after the owner is instructed as in above that you do not touch the system for 10 to 15 years,no the system will need to be pumped every 3 to 5 years. If the system is the basic septic tank with a D-box and wit pipe in rock laterals, the tank will still need pumped every 3 to 5 years. If there is any kind of secondary treatment after the septic tank, that portion will need to be looked at every 6 months, depending on how unique it is. (Septic tank with an outlet filter, pumping chamber with pump pump controls and alarms for a LPP lateral, ATU, single pass or recirc.sand filter, drip distribution, constructed wetland, rock filter, modified constructed wetland, trickle filter, D-box that can be maintained from the surface, ect.)
