The following table shows GSWSA plus North Myrtle Beach’s 20-year effluent disposal<br />
plan.<br />
c. Biosolids Disposal<br />
<br />
Wastewater treatment produces solids that are rich in natural fertilizers, <strong>and</strong> agricultural<br />
reuse of these treated biosolids provides a beneficial option for disposal. GSWSA has<br />
been treating <strong>and</strong> reusing bio-solids to grow sod at the High Tech Turf Farm in Socastee<br />
for 27 years. The sod is marketed locally <strong>and</strong> sales revenue offsets a significant part of<br />
the cost of solids treatment. About 25% of the Myrtle Beach generated bio-solids are<br />
composted <strong>and</strong> marketed locally with similar benefits. Biosolids are also applied to<br />
GSWSA tree farms to grow trees for harvest <strong>and</strong> sale, <strong>and</strong> to DHEC approved private<br />
farms.<br />
The projected annual biosolids production for <strong>2030</strong> is nearly 7,000 dry metric tons (2,205<br />
pounds/DMT). At 16 pounds of plant available nitrogen per DMT, this makes over<br />
100,000 pounds of nitrogen (PAN) available for reuse <strong>and</strong> recycling. GSWSA will<br />
exp<strong>and</strong> current programs so that all future bio-solids generation will continue to be<br />
reused.<br />
