Creates new provisions relating to public water supply districts

HB 1917 creates a new process for landowners in Missouri to seek detachment from a public water supply district. It allows owners of 50% or more of a land parcel not receiving water service to petition a circuit court for detachment if four conditions are met: no residents live there, no district water infrastructure is present, no district bonds are outstanding, and the land is in a qualifying county (with charter government, multiple water districts, or adjacent to a city in another county). The bill requires petitioners to submit legal descriptions, sworn affidavits, and certified mail notifications to the district and county offices. If county or district authorities fail to respond within 30 days on required checks, the court treats their silence as meeting the condition. This directly affects landowners seeking to exit a water district without service.
