FOR PRIVATE SEWAGE DISPOSAL SYSTEMS IN IMPERIAL COUNTY
The permit applicant needs to be aware of the following points concerning permit applications with the Environmental Health Services Section.
A. Applications for installation or repair permits must be accompanied by the following items in order to be deemed complete for processing and issuance:
1. Soil Percolation Report--Soil percolation testing is required to be conducted in the specific location where the proposed disposal field will be placed. Soil percolation testing must be done by a California-registered civil engineer. Percolation reports from other lots or other locations on the same lot will not be accepted.
2. Three copies of a site plan must be provided with sufficient detail and scale to provide the information required on the Site Plan Information sheet. It is to your advantage to verify with your engineer or the Environmental Health Services section what the minimum required disposal field size will be before finalizing your site plan. The disposal field must be accurately portrayed on the plan.
3. For projects having estimated maximum daily flow rates of 2500 gallons or more, the sewage disposal system must be designed by a California-registered engineer of your choice. The engineered design must be submitted to the department in duplicate for review and approval before the permit application will be deemed complete. A plan review fee will be required in addition to the permit fee described under item 5 below. Please contact the Environmental Health Services Section for the current amount of the fee.
4. In addition to the owner?s or contractor?s signature on the application form itself, three signatures from the same individual who signed the application are required on the Declaration Concerning Licensing & Insurance. If you are unsure of the correct places on the form to sign, please contact the Section of Environmental Health Services for explanation.
5. A application fee is required prior to issuance of a permit. Please contact the Environmental Health Services Section for the current amount of the fee.
It is policy that all permit applications be reviewed by the Imperial County Planning/Building Department for projects located in the unincorporated areas of Imperial County. If a disposal system is proposed within an incorporated city or sanitary district, the building/planning/sanitary department of jurisdiction must review the permit application and provide the Section of Environmental Health Services with written authorization before the permit may be issued. No permit will be issued without concurrence from the affected department(s).
