Do this first
Local water and sewer lines.
Both numbers come from the Missouri State Auditor's list of local governments.
- Shut off the water. Shut the main valve where the water line enters the house, or turn off the well pump breaker on a private well, before the water spreads to more rooms.
- Make it safe and document it. Cut power to wet rooms from a dry spot, photograph the damage, then report the claim.
- Start drying within 24 to 48 hours. Floodwater from the Platte River carries mud and sewage. Anything porous it soaked, like carpet pad and drywall, has to come out before drying starts.
