Hiram's water is split: the city serves in and around downtown, and Paulding County Water System serves the rest and runs the backflow program for its customers. Sewer connections go through Paulding County, which also issues plumbing permits. Call the number on this page to be connected with a local plumber in Hiram.

Signs a Hiram business needs a plumber
- A restaurant drain slowing by the end of each day
- Toilets in a shop or office that run between uses
- Wet ground between the meter and the building
- Drains slow across a building that isn't on sewer
- A Paulding County request for a backflow test form

Local conditions in Hiram
Hiram is a small, fast-growing city on the US 278 and GA-92 corridor in south Paulding County; its population grew from 1,361 in 2000 to 4,929 in 2020, and the median home dates to 2004. Most commercial buildings along the corridor are recent.
Water service is split. The City of Hiram provides water in and around downtown, through Public Works at 770-943-3726 ext. 3202. Everyone else is on Paulding County Water System, customer service 770-222-6868, with a 24-hour leak and emergency line at 770-445-2761. Paulding's water comes from Richland Creek Reservoir and treated water bought from the Cobb County-Marietta Water Authority.
For county water customers, Paulding's backflow and grease trap program applies. Testers must be on the GAWP certified tester list and must email current test-kit calibration certificates and completed test forms to the county. The City of Hiram's own requirements for its water customers weren't found in our sources.
Sewer runs through Paulding County too. The city-funded downtown sanitary sewer is owned and maintained by the county, which handles connections and tap fees, and parts of the area are not on municipal sewer. Permits come from Paulding County's Building and Permitting Division in Dallas, 770-443-7571, with inspections scheduled at 770-505-1398.
Cost factors
- Whether the building is on county sewer or a private onsite system
- Grease trap service and drain cleaning for food businesses
- Diagnostic time before the repair
- Off-hours scheduling
- County permit and inspection steps

Shopping center tenants along US 278 should check the lease to see whether the landlord handles the service line and building drain.
