Department of Public Utilities

What Department of Public Utilities does

The Department of Public Utilities (DPU) is the wholly owned municipal utility enterprise of the City of Orangeburg, South Carolina, delivering four regulated utility services — electricity, natural gas, water, and wastewater — to residential, commercial, and industrial customers across roughly 340 square miles of electric service territory and 260 square miles of water service territory. DPU owns and operates 22 electric substations (with voltages from 115KV down to 480V for large industrial customers) monitored through a fiber-optic dispatch network, 323 miles of natural gas distribution mains sourced via Carolina Gas Transmission, the John F. Pearson Water Treatment Plant (30 MGD capacity, drawing from the North Fork Edilo River, in operation since 1937), and a wastewater system serving approximately 10,700 customers through gravity lines, force mains, 19 pump stations, and a treatment plant featuring a 1997-installed biosolids dryer producing Class A "EQ" biosolids.

The customer base spans nearly 24,000 multi-utility accounts, over 60,000 water customers (including the Bull Swamp Rural Water Company territory acquired January 2024), and approximately 10,000 gas customers, with anchor commercial and industrial accounts including Husqvarna, GKN Aerospace, Zeus Industrial, SI Group, Okonite, Bimbo Bakeries, Gulbrandsen, SC State University, and MUSC of Orangeburg. Distribution is exclusively direct-to-consumer through owned infrastructure: customers can interact via a main-office drive-thru, three self-service kiosks, a 24-hour night depository, online bill pay (Invoice Cloud), 24/7 phone payments, mail payments, a Budget Billing program, and natural gas appliance rebates of $90-$250 to incentivize conversion from electric or propane.

Revenue is generated through subscription, monthly-billed recurring rate schedules organized into 20+ rate codes across the four services (including small/medium/large general service, demand-based, time-of-use, interruptible, EV charging, net metering, fire protection, wholesale, and rural classes). DPU's accounting function processes nearly $100 million in annual receipts and over 250,000 customer payments per year, with the utility claiming the lowest water/wastewater rates in the Southeastern U.S. and the lowest gas prices in South Carolina. Operational scale includes a fleet of roughly 110 on-road vehicles, nearly 12,000 invoices processed annually, and a 200-person regular full-time workforce organized into Administrative, Electric, Natural Gas, Water, Wastewater, and Fleet Maintenance divisions under Manager Warren Harley and a board of five Directors.
