The Local Agency Management Program (LAMP) develops minimum standards for the treatment and disposal of sewage through onsite wastewater treatment systems.

The County of San Luis Obispo LAMP is designed to protect surface water and groundwater from contamination while providing flexibility in design criteria in consideration of local conditions.
