At least three southeast Louisiana parishes are asking residents to conserve water during the current cold snap.

Plaquemines Parish is facing a "drastically reduced" water supply and reduced water pressure because of freeze-caused leaks, the parish's Office of Homeland Security and Emergency Preparedness said in a Facebook post.

While residents were asked to refrain from using water for non-essential uses, the report recommends leaving a slow drip from one faucet to keep water lines from freezing.

St. John the Baptist and St. James Parishes also asked residents to conserve water until the freezing weather passes. Officials offered these water conservation tips:

• Turn off the water when brushing teeth; use cup of water to rinse with.

• When shaving, place water in basin or sink rather than having it run continual.

• Use your dishwasher and clothes washer for full loads only.

• Minimize use of kitchen sink garbage disposal units.

• When washing dishes by hand, do not leave the water running for rinsing.

• Do not let the faucet run while you clean vegetables.

• Keep a bottle of drinking water in the fridge.
