Safe Water Use After a Typhoon: A Guide for Taipei Residents

As a newcomer to Taipei in Taiwan, one might notice a slightly yellow discoloration in the water supply following a typhoon. This is a common occurrence due to sediment, rust, or other contaminants that can enter the water supply during heavy rain and flooding. It is crucial to understand how to handle the situation to ensure the safety of you and your family.

Causes of Water Discoloration After a Typhoon

During and after a typhoon, various factors can contribute to the discoloration of your water:

Sediment and Rust: The heavy rainfall can stir up sediment and rust in water pipelines, leading to a discolored appearance. Contaminants: Flooding events can introduce contaminants such as debris, microorganisms, and chemical pollutants into the water supply.

Steps to Ensure Water Safety

If you notice a slight discoloration in your water supply, follow these steps to ensure its safety:

Avoid Drinking the Water

Do not drink the water until you can confirm its safety. Use bottled water for drinking and cooking to avoid any risks associated with potentially contaminated tap water.

Check Local Advisories

Stay informed by checking any announcements from local authorities or the water company regarding water quality. Updates on whether the water is safe to use can help you make an informed decision.

Run the Tap

If the discoloration is minor, running your tap for a few minutes can help clear the water. However, if the discoloration persists, it is best to avoid using the water until further notice.

Boil Water

Boiling water is an effective method to kill pathogens for cooking or brushing your teeth. However, this step will not remove chemical contaminants present in the water.

Contact Authorities

If you are concerned about the safety of your water supply, contact your local water authority for further guidance and assistance.

Using Water Safely for Everyday Needs

While you should avoid drinking or using the water for rinsing your mouth or brushing your teeth, the water can still be used for other purposes:

Flushing toilets and hand washing with soap are generally fine.

We recommend filtering and boiling water before drinking, especially before a storm or heavy rain. Some residents in Taipei store water in buckets and stainless steel containers to ensure they have a clean supply of water for household needs such as brushing teeth and washing fruits.

Water Filtration Systems

Water filtration systems can be highly beneficial, but it is essential to maintain them properly. Here are a few tips:

Regular Maintenance: Replace filters every 3-4 months to ensure optimal performance. DIY Filters: Consider making your own filter using materials like sand, charcoal, and other suitable resources. Ensure the sequence and cleaning procedures are properly followed.

While a filtered system can help remove many contaminants, it may not entirely eliminate all metal and bacteria. In cases where the water is particularly discolored, like a yellowish color, it is recommended to filter and boil the water to ensure it is safe for consumption.

Urging you to prioritize the safety of your water supply, especially after extreme weather events, is crucial for maintaining your household's health and well-being.
