What it means
Inlet and outlet baffles slow incoming wastewater and block floating scum and settled sludge from passing into the drain field. Concrete, plastic, or PVC tees perform the same job at the pipe connections.
Broken or missing baffles let solids carry over into effluent lines, which clogs filters, distribution boxes, and soil absorption areas. Inspection during pumping is the best time to check baffle condition.
Why it matters in Santa Cruz County
Older tanks in Santa Cruz County, including pre-1980 rural properties in Bonny Doon and the Summit area, often have deteriorated concrete baffles that need repair during routine maintenance.
Homeowner tip
Request a baffle check every time the tank is pumped and repair damaged tees before they foul the drain field.
