A 1903 railroad town that boomed in the 1970s
Piedmont sits in the northeast corner of Canadian County, with a small piece reaching north into Kingfisher County, about ten miles north of Yukon. Dr. E. H. Long started the townsite in 1903, and the St. Louis, El Reno and Western Railway made it a farm market town with grain elevators and cotton gins until the railroad left in 1924, according to the Oklahoma Historical Society. For decades the town stayed tiny: 146 people in 1960 and 269 in 1970.
Then Oklahoma City commuters discovered the large lots and rural setting. Piedmont jumped to 2,006 residents by 1980 and 7,394 by the 2020 census. The latest five-year Census estimates, covering 2020 to 2024, give a median build year of 2001. Of 2,894 housing units, 1,528 were built in 2000 or later, including 786 in the 2010s alone, and owners occupy about 91 percent of homes.
Newer homes have their own maintenance cycle. Many houses finished in the 2000s are due for their first water heater replacement, and original builder-grade faucets, toilets and pressure regulators are starting to wear. The smaller group of 1970s and 1980s acreage homes brings older supply lines and septic connections into the mix.
Piedmont water: wells, Oklahoma City and a lot of pipe
Piedmont's water comes from two places. The Piedmont Municipal Authority's 2026 water quality report lists three groundwater wells plus water purchased from Oklahoma City through a consecutive connection. The city's January 2024 Water Master Plan Update says most of the supply now comes from OKC, the wells are aging, and the city should add a second OKC connection with a new booster station.
The system is spread thin. The master plan describes roughly 123 miles of mostly PVC water lines across a service area of about 123 square miles, including part of the former Okarche Rural Water District. Its hydraulic model found low pressure during peak hours in the rural water district area and other areas above 100 psi, which the plan calls the pressure that affects customers' equipment, adding that complaints have occurred. It also notes that small water lines throughout Piedmont limit available fire flow, one reason the plan proposes miles of larger mains.
For homeowners, that makes pressure worth measuring. Readings above what your fixtures and water heater are rated for call for a pressure reducing valve, and weak pressure that never improves may point to a leak or restriction on your side of the meter.
Septic country with an older sewer core
Piedmont's public sewer covers only part of town. The city's 2040 Comprehensive Plan says the sanitary sewer serves mainly the downtown and central business areas, the majority of residential development is on septic systems, and most of the collection pipe is 50 to 70 years old. That pipe leads to a lagoon-style treatment plant, and the plan notes that most residents have their septic tanks emptied at that plant every few years.
If you are on septic, slow drains and gurgling toilets can mean a full tank, a clogged line between the house and the tank, or a struggling drain field. Our septic and pressure tank repair work covers the plumbing side of that system. The plan describes nearly flat to rolling plains draining to Deer Creek, Cottonwood Creek and Soldier Creek, with potential floodplain along parts of Deer Creek, so drainage around a tank and its lines deserves attention. Keep vehicles off the tank and lateral lines, and know where the lid is before you need it.
Wind, freezes and Piedmont permits
Open country means wind, and the city even brands itself with a windmill logo and the phrase Winds of Progress. On May 24, 2011, the EF-5 Calumet-El Reno-Piedmont-Guthrie tornado tracked west of Piedmont, and the National Weather Service in Norman reports that a Mesonet station west-northwest of El Reno measured a 151 mph gust during that storm. In winter, the same exposure drives cold air into attics, crawlspaces, garages and pump houses. On February 16, 2021, Oklahoma City dropped to minus 14°F, the second-coldest temperature in its records, according to the Oklahoma Climatological Survey.
Permits run through the Piedmont Community Development Department on Edmond Road NW. Most construction work requires a Piedmont Contractor's License, inspections are booked for the next business day with day-before scheduling, and the city's plumbing inspection list includes ground water and sewer, rough-in, sewer line, gas line pressure tests, gas meter resets and water heater change-outs.
