I'm in the same boat.We have on-site septic and (up gradiant) a shallow, spring-fed well.
It's always interesting to see how different parts of the country handle situations which we have exercise control over. Well, unless it's remediating conditions which lead to wildfires. As a country we, the US, do little of that. Then we encourage the homeless to camp out in neighborhoods and areas which are tinder dry. And, the expected result generates in a flurry of expensive fire suppression followed by a lot of hand wringing by the officials charged with the safety of humans.
Interesting to note, wildfires in the Russian Far East are largely caused by broken bottles focusing the sun into the tinder. The highway from Magadan to the airport in summer is usually bracketed on both sides of the road with wildfires. No real forests so the fires move slowly through the brush. Only fires near human habitation are attacked. So, lots of smoke followed by new foliage for the critters. The benefits of wildfires usually outweigh the destruction unless, it's your neighborhood that gets consumed.
Mother Nature has ways of slapping our pee-pees and telling us who is in real control.
