It means the treated effluent meets federal limits for fecal coliform bacteria and suspended solids before discharge.
Ahead Sanitation Systems carries only products that meet or exceed this standard. Whether you’re preparing for a Coast Guard inspection, or outfitting a new commercial build, our ahead tanks are the right specification.
