On September 15, 2022, DEHQ held the first Stakeholder input meeting to introduce the Local Agency Management Program (LAMP) evaluation and revision process. The next step is for our local stakeholders and community to provide thoughts/feedback. Stakeholder can pick from either viewing the Clean Copy version or version with Edits Copy in red lettering. Please use this linked feedback form to submit comments for consideration by December 1, 2022.
This is your opportunity to provide feedback and recommendations based on your real-world experience to support the Regional Board’s consideration of alternative standards for San Diego County.
The LAMP provides alternative standards than those set by the State Water Resources Control Board’s OWTS Policy and must still achieve the same water quality and public health protections. Please consider this Policy requirement when providing your feedback.
If you have any questions regarding the first draft of the LAMP, contact Linda Turkatte at Linda.Turkatte@sdcounty.ca.gov. If you have questions regarding the LAMP feedback form, contact Joann Fang Lee at Joann.Fang1@sdcounty.ca.gov.
A second revision of the LAMP will be issued in the Spring of 2023 for final review and feedback. Additional stakeholder and community engagement sessions will be held at that time.
Thank you for your support of our local program, your feedback is greatly appreciated.
Current Version: Local Agency Management Program
Wastewater Treatment System (OWTS) Policy
The purpose of regulating the design, installation, and maintenance
of onsite wastewater treatment systems (or, septic systems) is
- Ensure that these systems provide a safe and reliable means of wastewater treatment and disposal for properties not served by a sewer system
- Prevent the contamination of groundwater from improperly designed onsite wastewater treatment systems
- Prevent the contamination of surface water from improperly designed onsite wastewater treatment systems
- Prevent premature failure of onsite wastewater treatment systems
Program Services | Useful Information | Types of Systems
- Design review of new onsite wastewater treatment systems and Graywater Systems
- Design review of repairs and modifications to existing on-site wastewater treatment systems
- Installation inspections of onsite wastewater treatment systems
- Maintain design records for properties using onsite wastewater treatment systems
- Respond to citizen complaints of failing onsite wastewater treatment systems
- Provide coordinated review with other agencies for projects that require CEQA (California Environmental Quality Act) or involve the use of onsite wastewater treatment systems
- Provide review of discretionary land development projects that may involve DEHQ related permitting issues
Please note that a Project Issue Resolution Conference is available to applicants for discretionary land development projects processed through the County's Planning & Development Services:
Project Issue Resolution Conference
For land development projects processed through Planning & Development Services, a Project Issue Resolution (PIR) Conference is a meeting that includes an applicant, our Executive Management team, and County Project staff to discuss issues and identify solutions that were not able to be resolved with a County Project Manager due to interpretations of a code or other unique circumstances related to a project. The County is committed to helping customers navigate the land use permit process and ensuring customer satisfaction. The County recognizes land development can be complex and each project is unique. The goal of the PIR process is to help facilitate processing of each permit application in an efficient and timely manner by elevating technical project issues to our Executive Management team. For more information, please see PDS Page.
Currently, DEHQ is approving conventional system and supplemental treatment systems:
- Septic tanks must have IAPMO approval and be approved for use by DEHQ
- Leach lines can be constructed with either rock and pipe or other approved materials that would include plastic chambers
- Horizontal seepage pits are restricted to sites with uniform soil conditions and average percolation rates not exceeding 30 minutes per inch
- Vertical seepage pits are restricted to coastal sedimentary basins that have degraded groundwater caused by salt water intrusion
- Supplemental treatment systems must include percolation testing and a design from a licensed OWTS Professional
- Any site with slopes that exceed 25% must include with the layout a slope stability report or statement from a licensed civil engineer or geologist
