We have property in Delaware County Oklahoma and need to know what is the smallest size of a lot you can put a septic tank on?
How far does it need to be from your well?
Are there any lot line set backs?
Thanks for your help with this.

In Oklahoma, counties have no sovereignty--no legislative authority. They are strictly administrative subdivisions of state government. As such, they cannot pass ordinances. So, you'll have to go to state law for your answers.

Two places to start are:

Your well and septic systems are governed and permitted by the state. The local power company will do the electrical inspection. Other than that, there are no codes.

As afare as I know, three-quarter acre is smallest size for septic and you must hava a PERK test first before it can be installed.
The well and should must be separated by X feet to keep the water from accidentally being contaminated. Some areas of OK have a lot of clay and rock to drlll through to find water. It can be expensive - but maybe not as expensive as bringing in city water. .

I live in Delaware county and built a house 10 years ago and put in a septic tank. My lot is only 100 feet by 130 feet, much smaller then even 1/2 acre. I remember someone from the county came out and performed the perk test, don't remember anything else that needed to be done.
