Am looking at 12+ acres and would need something that could handle, hopefully, several hundred people a day on good days.
This might help:
REQUIREMENTS FOR A PRIVATE SEWAGE DISPOSAL SYSTEM WHEN THE PROPERTY IS NOT SERVED WITH SANITARY SEWER (Tulsa)
Permits for septic tank installations are issued through the Tulsa City/County Health Department,
Environmental Protection (HDEP). A soil percolation test must be performed or obtained from the
Oklahoma Department of Environmental Quality (DEQ). The percolation test can be performed by DEQ, a
Professional Engineer, or a Registered Professional Land Surveyor. DEQ will furnish you a design layout of
your sewage system. A new residence, structure or addition must be staked out prior to the HDEP final
field inspection. The following information needs to be included on the site plans.
1. Plumbing stub out, leading from the house to the septic tank.
2. Directional slope of the lot.
3. Structural landscaping, i.e., large trees, retaining walls, etc.
4. Any structures such as swimming pools, tennis courts, gazebos, driveways, and patios.
5. Number of proposed and/or existing bedrooms in the residence.
6. Automatic lawn irrigation systems.
7. Indicate if any part of the lot is in a flood sensitive area.
8. Street address and legal description of the construction site.
9. The builder's name, mailing address, and telephone number.
The following information must be included with the application.
1. A copy of result of the percolation test.
2. A copy of the final inspection on current systems.
These two items must be obtained from DEQ and brought to the Permit Center at the time of
application. These may be obtained at their office at 3105 E Skelly Dr, Suite 200 between the hours of
8:00 am and 4:30 pm (the inspectors are in the offices only from 8:00 am to 9:00 am). Any questions to
DEQ can be directed to 293-1600 during the hours above.
These two items must also be presented to the Tulsa City/County Health Department, Environmental
Protection (HDEP) for approval.
