Water Service Outages in Mount Pleasant, South Carolina

If the water is off in Mount Pleasant

1. Ask a neighbor. If they have water, check your own shutoff valve and meter before calling.
2. Report it to Mount Pleasant Waterworks and ask whether there is a main break or planned work on your street.
3. Turn off the water heater if the outage will be long, so an empty tank is not heated.
4. Check for a boil water advisory before drinking tap water after service returns.
5. Flush the cold tap for a few minutes once pressure is back.

Why is the water off in Mount Pleasant?

• Water main break. The most common cause of a sudden outage for a whole street. Crews shut the nearest valves, so homes on both sides of the break lose water until the repair is done.
• Planned work. Pipe replacement, valve work and new connections are usually announced a day or more ahead with door hangers, calls or a notice on the Mount Pleasant Waterworks website.
• Low pressure after a pump or power problem. Pump stations in Mount Pleasant run on electricity from Dominion Energy South Carolina. A long power outage or a pump failure can drop pressure for a whole area, especially upstairs and on higher ground, once backup generators or storage tanks run low.
• A problem only at your address. A closed shutoff valve, a meter replacement, a failed pressure regulator or a billing shutoff affects one home. If neighbors have water, start with these.

Weather and water outages in South Carolina

• Hurricanes and tropical storms. Flooding and long power cuts can knock out treatment plants and pump stations, and boil water notices often follow a storm in South Carolina. October falls inside that season.
• Winter storms. When power fails across a region, utilities without enough backup generators can lose pressure, as happens during long ice storms.

When will the water be back on?

A typical main break repair takes about 4 to 8 hours once the crew is on site, longer for large mains, deep pipes or breaks under busy roads. Planned work notices list a time window, and service often returns before it closes.

After service returns, a boil water notice can stay in place for a day or two. Lab tests for bacteria take about 24 hours, and the notice is lifted only after samples come back clean. Mount Pleasant Waterworks announces when it is safe to drink the water again.

Water outage map, zip code lookup and alerts for Mount Pleasant

We do not run a pipe map. The report count above shows whether other people in Mount Pleasant have reported water problems in the last 24 hours. For the official picture:

• Utility outage or main break page. Many utilities, including Mount Pleasant Waterworks, post active main breaks and planned shutoffs on their website, often on a map by street.
• Text and email alerts. Sign up with Mount Pleasant Waterworks for outage and boil water alerts for your address. It is faster than searching after the fact.
• By zip code. One zip code can be split between systems, so look up outages by street address or neighborhood rather than zip code.
• Local emergency alerts. County and city emergency alert services carry large outages and boil water notices.

Boil water notices in Mount Pleasant

A boil water notice is issued when pressure drops low enough for contamination to get in, after a main break, or when a routine test fails. In South Carolina, notices come from the water system itself, with oversight by the South Carolina Department of Environmental Services.

While a notice is in effect, bring water to a rolling boil for one minute (three minutes above 6,500 feet) or use bottled water for drinking, cooking, brushing teeth, ice and baby formula. What a notice requires, how much water to store and how restoration works are covered in our water outage guide.
