Supply stress
The vulnerability is in the source, not the supply volume. West Milton's 2025 CCR states that Troy's wellfield sits above a buried valley aquifer that 'provides limited natural protection' from infiltrating contamination, and that the aquifer supplying Troy is therefore considered highly susceptible to contamination; Troy runs a wellhead…

Sanitary
Village-operated, not county. The village utilities department runs its own wastewater treatment plant 24 hours a day; the February 2026 wastewater RFQ puts the collection and treatment system at roughly 2,200 wastewater customers for a population of about 4,700. A sanitary sewer trunk line replacement is underway and a full WWTP…
