The other thing I do quarterly, is add yeast to the septic tank. We've been in this house for 29 years this year, and I've done this since we moved in. About 15 years ago, we were doing some work (adding on), and had the yard torn up. My DH decided at that time since the yard was a mess anyway, that he would call in the "Honey Wagon" to clean out the septic tank. The "Honey Man" was impressed to find no solids in our septic tank at all. He advised that we should keep doing whatever we were doing, because it was working! My DH was impressed, since he always thought I was kinds "touched in the head" with the yeast thing. (go me!)
In the front cover of Martha Stewarts magazine, she has an organization calendar, and I've been using it to do the "extra stuff" that usually gets forgotten. Try it if you need motivation.
Have a wonderful week, and a blessed NEW YEAR!!!
