1975 I did my parents septic system in a lake community. Back then the Health Department was the go to source for info and inspections. I drew up a simple diagram showing property lines, house and the proposed system. The H.I. said I'm impressed with the detailed drawings most waltz in here with a cocktail napkin drawing and expect that to fly. I told the H.I. I was renting a back hoe on the weekend and dragging friends into this project. The H.I. told me not to back fill it in as he needed to inspect and take photos on Monday. , I reminded him that I was renting the back hoe the H.I. says to me I'm sure you have Polaroid camera, just take a few photos and that will be fine, I would never get away with that these days . That project was the last thing I did with my dad, he passed 5 weeks later.
