AI use disclosure

City pages are drafted with AI (Claude Sonnet 4.6), reviewed by our editorial team, and published only after passing uniqueness and factual-accuracy checks. One in every ten pages receives full human review.

What we do not do

• Do not publish fake reviews or fabricated contractor profiles.
• Do not claim DSPS POWTS credentials or DNR septage licenses we do not hold (we are a referral directory).
• Do not perform septic work — pumping, inspection, and installation are by independent DSPS-licensed contractors.
• Do not provide POWTS-code interpretation. SPS 383 adoption, county amendments, and AHJ requirements vary across Wisconsin counties; always defer to the county sanitarian or POWTS administrator with jurisdiction over your property.
