Residents and businesses in Granada Hills and Porter Ranch are being urged to conserve tap water while restoration efforts continue.

Meanwhile, parts of Malibu are no longer under a water boil notice, L.A. County Waterworks and State Water Resource officials announced Friday. Testing determined that the water is safe to drink.

Before using your water, officials are asking residents to flus outdoor hose spigots, indoor faucets and fixtures for at least two minutes or until the water runs clear.

These steps will help remove any remaining sediment or discoloration in the line.

What we know

In the Granada Hills and Porter Ranch areas, crews were making repairs at a pump station on Tuesday that connects to a 10 million gallon water tank. But a valve broke, cutting off water flow to the area’s pipes. The L.A. Department of Water and Power urged customers to conserve water Tuesday night, but the tank was drained by the morning.

According to Los Angeles County Public Works, the outage in Malibu was caused by Caltrans construction along the Pacific Coast Highway that prompted a drop in water pressure.

How do I know my water is safe enough to drink?

Water should be boiled for at least one minute and be left to cool before consuming. That includes water used for brushing teeth and making ice cubes.

If you can’t boil it, you can also use unscented liquid bleach, according to LADWP. Here’s how:

  • For clear water, use 8 drops (1/8 teaspoon) of bleach for one gallon of water. For cloudy water, filter through a clean cloth and use 16 drops (1/4 teaspoon) of bleach for one gallon of water. 
  • Mix well and allow it to stand for 30 minutes before using.
  • The water may taste or smell like chlorine — this means disinfection has occurred.
