Septic Tank Companies in Louisiana
107 septic service companies across 65 cities — approximately 18% of Louisiana homes use septic systems
Louisiana's onsite wastewater systems are regulated by the Louisiana Department of Health (LDH) through the Office of Public Health's Sanitary Engineering Section, under the Louisiana State Sanitary Code (LAC 51:XIII). The state's unique geography — vast areas of swampland, bayou country, and Mississippi River alluvial plain — creates some of the most challenging conditions for septic systems anywhere in the United States. Extremely high water tables, often within 12 inches of the surface in parishes like Terrebonne, Lafourche, and St. Bernard, have led Louisiana to widely adopt alternative systems including mound systems and low-pressure dosing systems that function where conventional gravity drain fields cannot.
