Sa 4 S.r.

About Sa 4 S.r.

The primary purpose of Sa 4 S.r. is tailings. Tailings dams contain waste material from mining operations — typically a slurry of finely ground rock left over after valuable minerals have been extracted. These structures require ongoing monitoring because tailings can contain heavy metals and other contaminants. The dam is owned by Pcs Phosphate (private). It impounds the Suwanne River near White Springs.

The dam stands 32 feet tall and stretches 26,306 feet across, creates a reservoir covering 880 acres, has a maximum storage capacity of 21,500 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1968, the structure is well into its service life at over 50 years old.

This dam has a low hazard potential classification, meaning that failure would cause minimal damage, limited primarily to the dam owner's property, with no expected loss of life. An emergency action plan is in place for this dam. The most recent inspection on record was 09/07/2005. That was over 20 years ago.

At 32 feet, this dam is taller than 76% of dams nationwide.
