Two boil advisories in two weeks

The frequency most households don't know about

The American Society of Civil Engineers estimates that a water main breaks somewhere in the United States every two minutes — roughly 700 breaks per day. The majority are repaired without triggering advisories, because pressure loss is contained or the break is isolated quickly. The ones that do trigger advisories are those where pressure across a larger distribution zone drops below the threshold that prevents backflow of ground contaminants into the pipe network.

The EPA tracked approximately 6,000 boil water advisories issued in 2023 across the US — roughly 16 per day on average. Many of these affect small systems; a fraction affect major urban areas. Atlanta's May advisory affected hundreds of thousands of customers. Oakland County's affected tens of thousands. Neither was a predictable or preventable event in the short term — they were the result of infrastructure that was built to a 100-year lifespan approaching the end of its design life.

The American Water Works Association estimated in its 2023 State of the Water Industry report that replacing US water distribution infrastructure — much of it cast iron and asbestos cement pipe installed in the 1930s through 1970s — would require $1 trillion over the next 25 years. That investment is not funded at anything approaching that scale. The reasonable expectation is that advisory frequency will remain elevated, and that major cities are not exempt.

What makes an advisory a crisis vs. an inconvenience

For a household with no stored water and no treatment capability, a boil water advisory that arrives at midnight means an immediate problem: nothing safe to drink, no way to make coffee, no reliable water for the children's morning routine. It means a scramble to buy bottled water from a store that may itself be under the advisory, or that has already sold out because 200,000 other households had the same idea.

For a household with 14 gallons of stored water per adult and a Sawyer Squeeze in a kitchen drawer, the same advisory is an inconvenience. Tap water is treated before use or avoided in favor of the stored supply; the advisory resolves in one to three days; and the household empties a couple of containers that get refilled and dated when service is restored.

The difference in experience between these two households is roughly $50 to $80 in containers and a portable filter — and the hour it takes to fill them.

The infrastructure picture going forward

The bipartisan infrastructure law signed in 2021 included $55 billion for water infrastructure — the largest federal water investment in US history. That funding is being distributed over five years through state revolving loan funds and direct grants. It will replace or rehabilitate meaningful infrastructure in prioritized systems, but it represents a fraction of the total replacement need.

The practical message is not alarm — it is that boil water advisories are a normal part of living on aging water infrastructure in the US, not a sign of exceptional failure. Planning for one, which requires minimal preparation, changes the experience from a crisis into a managed inconvenience.

What to do right now

1. 1 Store a 72-hour water supply minimum. Most boil water advisories resolve in one to three days. At 1.5 gallons per person, that is roughly 4 to 5 gallons per adult — two Aqua-Tainer containers total for a couple. This one step handles the overwhelming majority of advisory scenarios.
2. 2 Keep a Sawyer Squeeze in the kitchen, not in storage. It is useful when the advisory arrives — not when you go looking for it three days later. A filter in the kitchen drawer means water access from any available source, treated appropriately.
3. 3 Sign up for your local emergency notification system. Advisory notifications arrive fastest through direct utility alerts and local emergency management systems — faster than local news, faster than social media. Most utilities offer text and email alerts at no cost.
4. 4 Review the boil water protocol before you need it. The full CDC guidance — what requires boiled water, what does not, what to do when the advisory is lifted — is worth reading once and keeping accessible. See the full protocol in the previous field note.
