No permit, perk test, enforcement officer or engineer drawing here. All those are just for control and money grab. Everybody wants a piece of the pie. I installed mine 22 years ago this month. I did everything. It's been pumped once. The field is a 40' closed H pattern. I can tell it's still working during the summer months--The grass is green over the field.
Ran my own water from the meter (1200'), well (800') and power lines from
my poles too (100',100', 300').
And, while we're at it; Put in my own 1400' driveway and property fencing. This ain't no lot in the city, you know.
