It's important to note that irrigation accounts require you to install a backflow prevention device and have it tested annually by an approved tester. A certified plumber or contractor can install a backflow preventer for you. The cost will depend on the type of device required and the installation labor.
Tap and impact fees cover the cost for the Charleston Water System distribution system to install and connect the new meter. A $30 account origination fee is also charged for creation of the new account. This fee is nonrefundable and nontransferable.

Most customers see a payback on the up-front cost of installing the irrigation meter in 4 to 5 years. For a savings and payback period estimate, call (843) 727-6800, or email us. One important thing to consider is how getting an irrigation meter will affect your domestic sewer bill if you live in a single family home. You won't pay any sewer charges for water use through an irrigation meter, but your sewer bill for your residential account will increase slightly because your domestic sewer charges will be calculated based on 100% of your domestic water usage instead of 95%.
Additionally, our backflow requirements must be met before we will activate the irrigation service. We require irrigation accounts to have a backflow prevention assembly in order to protect our water system against contamination from backflow.
Charleston Water System does not install or test backflow preventers. Customers are responsible for installing backflow preventers in accordance with our requirements and having them tested annually.
