Amending local surface water runoff system authority.

HB 180 requires cities and towns in Wyoming to address surface water runoff systems established before April 1, 2026. By July 1, 2027, these systems must either be reorganized into a drainage utility (with voter approval) or operated using only city funds without user fees after April 1, 2026. If cities fail to comply by the deadline, they must refund all fees collected before April 1, 2026 to users by September 1, 2027. The bill also allows fees for other services (like water or trash) but prohibits new fees for runoff systems after 2026.
