Welcome to the Isle of Palms Water and Sewer Commission

Our mission is to provide superior services and quality products in an efficient and productive manner through continuous improvement in organizational skills and assets, without negative environmental impact, and at the lowest possible cost.

Coming Soon - - Online Bill Paying!

Isle of Palms Water and Sewer Commission (IOPWSC) is pleased to announce our new Online Billing and Payment System scheduled to be released at the end of April.

Our new service will only be accessed through our secure website and will use the highest industry standards for protected processing.

The IOPWSC new service will allow you to:

  • View and receive your bills online
  • Receive reminders and receipts by email
  • Pay online or by text
  • Pay with credit/debit cards
  • Auto-pay your utility bills directly from your bank
  • Schedule your payments online
  • Confirm your payments were received
  • Allow you to go paperless

Do NOT be fooled by any other online bill payment or account management systems; they are not authorized by IOPWSC to collect payment for your utility bill. Using these systems will, at best, result in unnecessary high additional fees to you.

If you have any questions regarding how you currently pay your utility bill please come see us or call customer service at (843) 886-6148.

Freezing Temperatures and Frozen Pipes

When temperatures dip below freezing, exposed water pipes and fixtures are at risk of freezing. Depending on the type of pipes you have, the expansion that occurs when water freezes can cause pipes to break.

Tips to Protect Plumbing


Disconnect hoses from outdoor spigots. It is also a good idea to insulate the spigot with a cover.


Insulate exposed pipes and backflow preventers. Wrap them with towels or blankets, or buy foam pipe insulation at a hardware store. Wrap backflow preventers in plastic, or buy a cover.

Leave Faucet Dripping

If you are home, let an indoor faucet drip overnight. This is ideal for older homes with a crawl space and uninsulated pipes. Flowing water is less likely to freeze. If you have a two-story home, let a faucet on the first floor drip. Make sure the drain is not blocked, and remember to turn off the water in the morning.

Locate Shut-Off Valve

Know where your home's water shut-off valve is and how to use it. For most single-family homes, it is located in the ground near your outdoor spigot, in line with your water meter. It is important to keep the shut-off value clear of overgrowth and easy to access. In the event of a pipe break or other water leak in your home, you can use this valve to turn off the water supply, which will prevent water damage.

Discovering Frozen Pipes

During extremely cold weather, if you have little to no water flow when you turn on the faucet, your pipes may be frozen. Frozen pipes will thaw as daytime temperatures rise, but keep the following in mind:
  • If you are going to be at home, open a faucet and wait until water begins flowing again. Listen for leaks; water expands when it freezes, which can cause leaks in pipes. If you discover a leak, turn off the water supply to your home at the main shut-off valve, and contact a plumber.                          ‚Äč
  • If you are planning to leave your home, turn off your water supply at the main shut-off valve. This will prevent water damage from potential leaks in your plumbing. If you have a leak, contact a plumber.
