Dear SIUC Customer,


This letter is to inform you of new water and sewer fees effective January 1, 2023. The sewer base fee increase is 9 % per month for all customer categories. 


                Sewer Base Fee (1 ERU)          $ 49.70      Within Town of Seabrook Island

                                                                    $ 52.00       Kiawah River Estates & Cassique


The water usage rate will increase in January from $ 5.00/1000 gallons to $ 5.50/1000 gallons. This increase includes a pass-through rate increase from St. Johns Water. The water base fee, $ 24.55 per month, will not increase.


The Commission is committed to managing costs, staying efficient and upholding its mission to provide customers safe, reliable potable water and sanitary sewer services. The Commission relies solely on monthly fee collection to cover all the costs for the services it provides. Much time, thought and analysis were performed in this high inflation environment where the utility was exposed to both equipment and consumable price increases as well as significantly increased employee costs.


The additional revenue will not only support rising operational expenses, but also help provide a source for repairing and/or replacing aging infrastructure. Capital projects planned for 2023 include water meter replacement, continued sewer line and manhole condition assessment, and #2 secondary clarifier rebuild.  These rate increases do not reflect future costs driven by new customers coming onto our system.  New customer costs are collected separately by an impact fee paid by customers when they connect to the system.


As a reminder, invoices are issued on the last day of each month and payment is due on the 25th of the following month. SIUC offers auto draft, the worry-free way to pay your utility bill. With this service, the amount of your monthly bill is automatically deducted from your bank account and credited to your utility account. The application can be found on our website siuc.org. The website provides general information, helpful tips, news, and a list of rates/fees. Visit siuc.org and sign up to receive email alerts for service-related issues and utility news.
