Water wells in Harrah, OK
Harrah, along the North Canadian River in far eastern Oklahoma County, still asks about wells on its paperwork: the City's residential building permit form has owners check either city water or private well (Harrah residential building permit form). Outside the water mains, new homes on acreage usually mean a new well.
River land versus upland
Lots near the river bottom and on higher ground can behave differently. Casing must rise at least 24 inches above ground where flooding is known, instead of the usual 12 inches (OAC 785:35-7-1). Ask your driller which applies to your site.
Depth and price range
For Oklahoma County as a whole, OWRB records show a 200-foot median depth, and the modeled cost of a complete well with pump and tank is $12,000 to $20,000 (OWRB-based cost index). Statewide guides put drilling at roughly $25 to $55 per foot (WellDrillingCosts.com, Oklahoma).
Harrah checklist
- Mark "private well" on the building permit if that is your supply, and ask the City what it needs from the driller.
- Test new water for bacteria and nitrate before the family drinks it (OSU Extension: Well Water Basics).
- Plan the well and septic layout together; a 20-foot surface seal is required when a level or downhill well is only 50 to 75 feet from a septic tank (OAC 785:35-7-1).
Older farm wells
Older Harrah properties may still have hand-dug or shallow wells from decades ago. If an old well will no longer be used, OWRB rules make the driller and owner responsible for proper maintenance, plugging and capping (OAC 785:35-7-1). An open, abandoned casing is a direct path for surface water into the aquifer, so plugging it is worth pricing alongside the new well.
